Supporter and electroacoustic transducer device

A supporter for use in an electroacoustic transducer device including a housing and an electroacoustic transducer mounted to the housing using the supporter, the supporter including: a truncated conical shaped body including: a first portion configured to be held in contact with the electroacoustic transducer at a first position; and a second portion configured to be held in contact with the housing at a second position, wherein the second position is disposed spaced from the first position along an axial direction of an axis of the truncated conical shaped body.

BACKGROUND

Technical Field

The following disclosure relates to an electroacoustic transducer device, such as a microphone or a speaker, configured to convert between a sound and an electric signal representing a waveform of the sound, and relates to a supporter used in the electroacoustic transducer device.

Description of Related Art

Noise may be generated in an electroacoustic transducer device if a vibration is transmitted to an electroacoustic transducer that converts between a sound and an electric signal representing a waveform of the sound. The electric signal will be hereinafter referred to as “sound signal” where appropriate. One example of the noise is handling noise generated in a handheld microphone. The handling noise is generated when a vibration is transmitted from a hand holding the microphone to a housing of the microphone and then to the electroacoustic transducer supported in the housing, and a sound signal containing a vibration component is thereby output.

To reduce the handling noise, a structure for supporting the electroacoustic transducer with respect to the housing has been proposed. In this structure, an insulator (hereinafter referred to as “supporter” where appropriate) formed of an elastic material such as rubber is interposed between the electroacoustic transducer and the housing. For instance, Patent Document 1 (Japanese Examined Utility Model Registration Application Publication No. 7-9506) discloses using, as the supporter, a rubber ring in which a plurality of holes (or grooves) are formed in a circumferential direction of the rubber ring.

SUMMARY

In a case where the handling noise is reduced using the supporter, the handling noise is more effectively reduced with an increase in an area of the supporter in which the supporter undergoes shear deformation. This is because a resonance frequency of a vibration generated in a head portion of the microphone is shifted toward a lower frequency side with an increase in the area that undergoes shear deformation, so that the handling noise can be shifted toward a lower frequency side that is lower than a lower limit of a band used for the microphone. In the rubber ring indicated above, the area that undergoes shear deformation may be increased by increasing a ring width in plan view while decreasing the thickness of the rubber ring. It is, however, difficult for the rubber ring incorporated in the handheld microphone for vibration damping purpose to have an increased ring width due to limitation in size in the radial direction. It is noted that noise may be generated in a stationary microphone as experienced in the handheld microphone, due to the vibration transmitted to the electroacoustic transducer via the housing of the electroacoustic transducer device. Further, such noise may be generated not only in microphones but also in speakers.

Accordingly, one aspect of the present disclosure is directed to a technique of enhancing an effect of reducing the handling noise without involving an increase in size in the radial direction of the supporter that supports the electroacoustic transducer with respect to the housing of the electroacoustic transducer device.

In one aspect of the present disclosure, a supporter for use in an electroacoustic transducer device including a housing and an electroacoustic transducer mounted to the housing using the supporter includes: a truncated conical shaped body including: a first portion configured to be held in contact with the electroacoustic transducer at a first position; and a second portion configured to be held in contact with the housing at a second position, wherein the second position is disposed spaced from the first position along an axial direction of an axis of the truncated conical shaped body.

In another aspect of the present disclosure, an electroacoustic transducer device includes: a housing; an electroacoustic transducer; and a supporter mounting the electroacoustic transducer to the housing. The supporter including a truncated conical shaped body includes: a first portion held in contact with the electroacoustic transducer at a first position; and a second portion held in contact with the housing at a second position, wherein the second position is disposed spaced from the first position along an axial direction of an axis of the truncated conical shaped body.

DETAILED DESCRIPTION OF THE EMBODIMENTS

There will be hereinafter described embodiments of the present disclosure.

A. First Embodiment

FIG. 1is a partial cross-sectional view of a microphone1A according to a first embodiment. The microphone1A is a handheld microphone having a substantially cylindrical shape.FIG. 1is a cross-sectional view of a head portion of the microphone1A, taken along a plane including a central axis of the microphone1A (i.e., a central axis of the cylindrical shape). As illustrated inFIG. 1, the microphone1A includes: a housing10; a microphone capsule20; a supporter30A supporting the microphone capsule20with respect to the housing10; and a windshield40covering the microphone capsule20.

The housing10is a cylindrical member formed of resin or metal. When using the microphone1A, a user holds the housing10such that the windshield40faces vertically upward. The windshield40is formed of metal mesh, for instance. The windshield40allows sounds having arrived from the outside to pass through the windshield40to an inner space defined by the windshield40and the housing10. As illustrated inFIG. 1, the microphone capsule20is supported by the supporter30A (as one example of “supporter”) in the inner space.

The microphone capsule20is a substantially cylindrical member having a diameter smaller than that of the housing10. The microphone capsule20includes: a diaphragm formed of synthetic resin or metal; and an electroacoustic transducer configured to convert a vibration of the diaphragm caused by sounds having arrived from the outside, to sound signals and output the sound signals. InFIG. 1, illustration of the diaphragm and the electroacoustic transducer is omitted. The electroacoustic transducer may have a configuration similar to that of an electroacoustic transducer of conventional microphones. Specifically, the electroacoustic transducer includes: a voice coil connected to the diaphragm; and magnets and a yoke that generate a magnetic field interlinked with the voice coil.

The supporter30A is a cylindrical member having an inverted truncated conical shape and formed of an elastic material such as fluororubber. That is, the supporter30A is formed in a hollow, inverted truncated conical shape having a circumferential wall with a predetermined thickness. The supporter30A has opposite end faces orthogonal to a central axis of the supporter30A (i.e., a rotation axis of the inverted truncated conical shape). In the following description, one of the end faces having a radius smaller than that of the other of the end faces will be referred to as “first end face”, and the other will be referred to as “second end face”. The supporter30A further has a circumferential wall315A connecting the first end face and the second end face.

As described above, the microphone1A of the present embodiment is held by the user such that the windshield40faces vertically upward. In this state, the supporter30A is attached to the housing10such that the first end face is oriented in a vertically downward direction, namely, in a direction indicated by an arrow X inFIG. 1. The first end face of the supporter30A has an inside diameter that is substantially equal to an outside diameter of the microphone capsule20. An inner circumferential portion of the first end face is held in contact with the microphone capsule20and functions as a first portion310that supports the microphone capsule20. The second end of the supporter30A has an outside diameter that is substantially equal to an inside diameter of the housing10. An outer circumferential portion of the second end face functions as a second portion320that is held in contact with the housing10. The second portion320is held in contact with an inner circumferential surface of the housing10, whereby the supporter30A is supported with respect to the housing10. In the microphone1A of the present embodiment, the first portion310and the second portion320are located at mutually different height levels in the axial direction of the supporter30A. In a state in which the microphone1A is held by the user such that the windshield40and the microphone capsule20face vertically upward and the central axis of the supporter30A extends in parallel with the vertical direction, the first portion310is located at a height level lower than that of the second portion320. The circumferential wall315A extends from the first portion310to the second portion320and is shaped such that an inside diameter of the circumferential wall315A increases in a direction from the first portion310toward the second portion320.

An area in the supporter30A at which the supporter30A undergoes shear deformation is the circumferential wall315A. By increasing the size of the supporter30A in the central axis direction, namely, by increasing the height of the truncated conical shape, the area that undergoes shear deformation can be increased without involving an increase in size in the radial direction. Thus, as compared with a configuration in which the electroacoustic transducer is supported by a flat, ring-shaped supporter, the supporter30A of the present embodiment ensures an enhanced effect of reducing the handling noise without increasing the size of the supporter in the radial direction.

In the first embodiment, the first portion310is located at a height level lower than that of the second portion320in a state in which the central axis of the supporter30A extends in parallel with the vertical direction (i.e., the X direction inFIG. 1). The configuration may be modified such that the supporter30A is attached upside down to the housing10and the second portion320is located at a height level lower than that of the first portion310. This modified configuration can also enhance the effect of reducing the handling noise without increasing the size of the supporter in the radial direction, as compared with the configuration in which the electroacoustic transducer is supported by the flat, ring-shaped supporter. It is noted, however, that the position of the center of gravity of the microphone capsule20(the electroacoustic transducer) with respect to the housing10is lower and the stability of the microphone1A is higher in the configuration of the embodiment in which the first portion310is located at a height level lower than that of the second portion320, as compared with the modified configuration in which the second portion320is located at a height level lower than that of the first portion310. Thus, the configuration according to the present embodiment is preferable.

B. Second Embodiment

FIG. 2is a perspective view illustrating an external appearance of a supporter30B according to a second embodiment, andFIG. 3is a plan view of the supporter30B viewed on a second-end-face side of the supporter30B. As illustrated inFIGS. 2 and 3, the supporter30B differs from the supporter30A of the first embodiment in that the supporter30B has holes (slots or cutouts)330formed on a circumferential wall315B. Specifically, three holes330each extending in the circumferential direction of the circumferential wall315B are formed on the circumferential wall315B such that a planar shape of the supporter30B viewed in the central axis direction has three-fold rotation symmetry (i.e., 120-degree rotation symmetry) about the central axis. The three holes330are formed so as to be shifted relative to each other in the circumferential direction of the circumferential wall315B and so as to partly overlap each other in the circumferential direction. That is, a range in the circumferential direction of the circumferential wall315B over which one of the three holes330is formed partly overlaps each of ranges in the circumferential direction over which are respectively formed two of the three holes330that are adjacent to the one of the three holes330in the circumferential direction. Thus, the three holes330are formed such that a line segment AB drawn in the radial direction in a planar shape of the circumferential wall315B when the supporter30B is viewed in the central axis direction extends inevitably across at least one of the three holes330. In other words, the three holes330are formed such that, in the planar shape of the circumferential wall315B when the supporter30B is viewed in the central axis direction, the line segment AB, which indicates the shortest path on the circumferential wall315B from a point on the first end face (i.e., the first portion310) to a point on the second end face (i.e., the second portion320), extends inevitably across at least one of the three holes330at any position in the circumferential direction of the circumferential wall315B.

Each of the three holes330includes: a first-diameter hole section330B1(as one example of “first formed portion”) extending in the circumferential direction of the circumferential wall315B; a second-diameter hole section330B2(as one example of “second formed portion”) extending in the circumferential direction of the circumferential wall315B; and a cutout330B. The first-diameter hole section330B1is a part of the hole330. The first-diameter hole section330B is formed at a first-diameter region of the circumferential wall315B having a first diameter larger than the inside diameter of the first portion310(the first end face). The three first-diameter hole sections330B1are disposed so as to be equally spaced apart from each other in the circumferential direction of the circumferential wall315B. The second-diameter hole section330B2is a part of the hole330. The second-diameter hole section330B is formed at a second-diameter region of the circumferential wall315B having a second diameter larger than the first diameter. The three second-diameter hole sections330B2are disposed so as to be equally spaced apart from each other in the circumferential direction of the circumferential wall315B. The cutout330B3is a part of the hole330. The cutout330B3is disposed between one end of the first-diameter hole section330B1and one end of the second-diameter hole section330B2to connect the one end of the first-diameter hole section330B1and the one end of the second-diameter hole section330B2. As illustrated inFIG. 3, the three first-diameter hole sections330B1and the three second-diameter hole sections330B2are shifted relative to each other in the circumferential direction and partly overlap relative to each other in the circumferential direction. That is, a range in the circumferential direction of the circumferential wall315B over which one of the three first-diameter hole sections330B1is formed partly overlaps each of ranges in the circumferential direction of the circumferential wall315B over which are respectively formed two of the three second-diameter hole sections330B2that are adjacent to the one of the first-diameter hole sections330B in the circumferential direction. In this configuration, the three first-diameter hole sections330B1and the three second-diameter hole sections330B2are formed such that, in the planar shape of the circumferential wall315B when the supporter30B is viewed in the central axis direction, the line segment AB drawn in the radial direction extends inevitably across a) one of the first-diameter hole sections330B1, b) one of the second-diameter hole sections330B2or c) one of the first-diameter hole sections330B1and one of the second-diameter hole sections330B2. In other words, the three first-diameter hole sections330B1and the three second-diameter hole sections330B2are formed such that, in the above-indicated planar shape of the circumferential wall315B, the line segment AB that indicates the shortest path from the point on the first end face (i.e., the first portion310) to the point on the second end face (i.e., the second portion320) extends inevitably across a) one of the three the first-diameter hole sections330B1, b) one of the three second-diameter hole sections330B2or c) one of the three the first-diameter hole sections330B1and one of the three second-diameter hole sections330B2, at any position in the circumferential direction of the circumferential wall315B. In other words, the plurality of slots are arranged so that a line extending in a radial direction of the truncated conical shaped body, in a view taken along a planar elevational view, intersects at least one of the plurality of slots. In the present embodiment, the supporter30is constructed as illustrated inFIGS. 2 and 3for the following reasons.

By forming the holes on the circumferential wall of the supporter having the inverted truncated conical shape illustrated in the first embodiment, the circumferential wall of the supporter more easily undergoes shear deformation, as compared with the first embodiment. The applicant of the present disclosure has conducted experiments for examining a relationship between: the number, the size, and the position, of the holes formed on the circumferential wall of the supporter having the inverted truncated conical shape; and frequency response of the supporter.

Specifically, the applicant measured the frequency response for: a supporter (case1) not having holes on the circumferential wall like the supporter30A of the first embodiment; and supporters (cases2-4illustrated inFIG. 4) having the holes on the circumferential wall. As illustrated inFIG. 4, the supporter of case2has three holes disposed in rotation symmetry, the supporter of case3has six holes disposed in rotation symmetry, and the supporter of case4has twelve holes disposed in rotation symmetry. The holes of the supporters of cases2-4have the same length D in the radial direction. Each hole of the supporter of case3has a length L′ in the circumferential direction that is half a length L in the circumferential direction of each hole of the supporter of case2. Each hole of the supporter of case4has a length L″ in the circumferential direction that is half the length L′ in the circumferential direction of each hole of the supporter of the case3. In the supporters of cases2-4, the holes are thus arranged for allowing an area of a portion of the circumferential wall at which the holes are not formed to be the same among the supporters of cases2-4. Further, the holes are disposed in rotation symmetry in each of the supporters of cases2-4for preventing the microphone capsule20from being inclined when supported by the supporter.FIG. 5indicates measurement results of the frequency response in the supporters of cases1-4. It is to be understood from the measurement results ofFIG. 5that the resonance frequency of the vibration generated in the head portion of the microphone is shifted toward a low frequency side, namely, shear deformation more easily occurs, owing to provision of the holes on the circumferential wall of the supporter. It is to be further understood that the amount of shift in frequency does not depend on the number of holes if the total area of the holes is the same among the supporters.

The applicant of the present disclosure measured frequency response for supporters of cases5-7illustrated inFIG. 6. In each of the supporters of cases5-7, three holes are disposed in rotation symmetry. The holes of the supporters of cases5-7have the same length L in the circumferential direction. However, the length D of the hole in the radial direction is made different among the supports of cases5-7, i.e., cases5-7: D<D′<D″ as illustrated inFIG. 6.FIG. 7indicates measurement results. It is to be understood from the measurement results ofFIG. 7that the resonance frequency of the vibration generated in the head portion of the microphone is shifted toward a lower frequency side with an increase in the length of the hole in the radial direction.

As illustrated inFIG. 8, the applicant of the present disclosure measured frequency response for supporters (cases8-10). In the supporter of case8, three pairs of holes are disposed in rotation symmetry, two holes in each pair being arranged in the radial direction and extending in the circumferential direction. In the supporter of case9, the two holes arranged in the radial direction are shifted relative to each other in the circumferential direction by 30 degrees. In the supporter of case10, the two holes arranged in the radial direction are shifted relative to each other in the circumferential direction by 60 degrees.FIG. 9indicates measurement results. It is to be understood from the measurement results ofFIG. 9that the resonance frequency of the vibration generated in the head portion of the microphone is shifted toward a lower frequency side with an increase in an amount by which the holes arranged in the radial direction are shifted relative to each other in the circumferential direction, i.e., a shift amount. Here, by shifting the positional relationship of the holes arranged in the radial direction, the resonance frequency of the vibration generated in the head portion of the microphone is shifted toward a lower frequency side for the following reasons.

As for the supporter of case8illustrated inFIG. 8, the shortest path AB (i.e., the shortest path that does not pass across any holes330) along the circumferential wall from the microphone capsule20to the housing10is equal to a line segment drawn in the radial direction along the circumferential wall, as illustrated inFIG. 10. As for the supporter of case10illustrated inFIG. 8, a line segment drawn in the radial direction extends inevitably across at least one of the plurality of holes. That is, in the supporter of case10illustrated inFIG. 8, the shortest path AB (i.e., the shortest path that does not pass across any holes330) along the circumferential wall from the microphone capsule20to the housing10is larger, as compared with that of the supporter of case8. Thus, the supporter of case10includes, along the shortest path AB (i.e., the shortest path that does not pass across any holes330), a narrow width portion in which the width is locally small, as indicated by a portion enclosed by dashed line inFIG. 11. Owing to the narrow width portion, shear deformation is allowed to occur easily in the circumferential direction in the supporter of case10, as compared with the supporter of case8, so that the resonance frequency of the vibration generated in the head portion of the microphone is shifted toward a low frequency side. As illustrated inFIG. 11, a supporter30B2of the present embodiment corresponding to the supporter of case10includes three first holes330B12(each as one example of “first formed portion”) extending in the circumferential direction of the circumferential wall315B and three second holes330B22(each as one example of “second formed portion”) extending in the circumferential direction of the circumferential wall315B. Like the first-diameter hole section330B1ofFIG. 3, each of the three first holes330B12is formed at the first-diameter region of the circumferential wall315B having the first diameter larger than the inside diameter of the first portion310(i.e., the first end face). The three first holes330B12are disposed so as to be equally spaced apart from each other in the circumferential direction of the circumferential wall315B. Like the second-diameter hole section330B2ofFIG. 3, the three second holes330B22are formed at the second-diameter region of the circumferential wall315B having the second diameter larger than the first diameter. The three second holes330B22are disposed so as to be spaced apart from each other in the circumferential direction of the circumferential wall315B. One of the three first holes330B12and a corresponding one of the three second holes330B22are shifted relative to each other in the circumferential direction of the circumferential wall315B. The three first holes330B12and the three second holes330B22are shifted relative to each other in the circumferential direction and partly overlap relative to each other in the circumferential direction. That is, a range in the circumferential direction of the circumferential wall315B over which one of the three first holes330B12is formed partly overlaps each of ranges in the circumferential direction of the circumferential wall315B over which are respectively formed two of the three second holes330B22that are adjacent to the one of the three first holes330B12in the circumferential direction. In this configuration, the three first holes330B12and the three second holes330B22are formed such that, in the planar shape of the circumferential wall315B when the supporter30B2is viewed in the central axis, a line segment AB drawn in the radial direction (similar to that inFIG. 3) extends inevitably across a) one of the three first holes330B12, b) one of the three second holes330B22or c) one of the three first holes330B12and one of the three second holes330B22. In other words, the three first holes330B12and the three second holes330B22are formed such that, in the above-indicated planar shape of the circumferential wall315B, a line segment (similar to that inFIG. 3) that indicates the shortest path from a point on the first end face (i.e., the first portion310) to a point on the second end face (i.e., the second portion320) extends inevitably across a) one of the three first holes330B12, b) one of the three second holes330B22or c) one of the three first holes330B12and one of the three second holes330B22, at any position in the circumferential direction of the circumferential wall315B.

The amount by which the first hole330B12and the second hole330B22arranged in the radial direction are shifted relative to each other is not limited to 60 degrees. The shift amount may be determined to allow the shortest path along the circumferential wall from the microphone capsule20to the housing10to be as long as possible. In other words, the shift amount may be determined to allow the line segment drawn in the radial direction in the planar shape of the supporter to extend inevitably across at least one of the plurality of holes formed on the circumferential wall of the supporter.

In view of the above observation, as illustrated inFIG. 3, the supporter30B according to the present embodiment includes three pairs of the holes330B1,330B2disposed in rotation symmetry, the two holes330B1,330B2in each pair being arranged in the radial direction and extending in the circumferential direction. In addition, the supporter30B according to the present embodiment includes the cutouts330B3(one of which is indicated by a portion enclosed by dashed line inFIG. 3). Each cutout330B3connects corresponding holes330B1,330B2arranged in the radial direction so as to allow the two holes330B1,330B2to function as one hole. The cutout330B3is one example of “connecting portion”. The cutouts330B3allow shear deformation in the circumferential direction to occur as easily as possible. It is considered that shear deformation in the circumferential direction occurs more easily in a supporter30B3illustrated inFIG. 12in which two holes3303, each including a first-diameter hole section330B13and a second-diameter hole section330B23, are disposed such that a planar shape of the supporter30B3viewed in the axial direction has two-fold rotation symmetry about the axis. However, the stability with which the microphone capsule20is supported is lower in the supporter30B3ofFIG. 12than in the supporter30B ofFIGS. 2 and 3. This is because the supporter30B ofFIGS. 2 and 3can support the microphone capsule20at three points in accordance with the symmetry of the supporter30B as a whole (three-fold rotation symmetry) whereas the supporter30B3ofFIG. 12supports the microphone capsule20at two points. It is thus preferable to employ three-fold rotation symmetry illustrated inFIG. 2andFIG. 3.

As explained above, as compared with the conventional configuration in which the electroacoustic transducer is supported with respect to the housing of the electroacoustic transducer device by the flat, ring-shaped supporter, the supporter in the present embodiment enhances the effect of reducing the noise without increasing the size of the supporter in the radial direction. Moreover, the supporter in the present embodiment ensures a higher effect of reducing the noise than the supporter of the first embodiment.

In the first embodiment, the microphone1has only one supporter30A having the inverted truncated conical shape. The microphone capsule20may be supported by a plurality of the supporters30A.FIG. 13is a cross-sectional view of a head portion of a microphone1C in which the microphone capsule20is supported by the two supporters30A. By supporting the microphone capsule20by the plurality of the supporters30A, the stability with which the microphone capsule20is supported is higher in the third embodiment than in the first embodiment or the second embodiment in which the microphone capsule20is supported by the single supporter having the inverted truncated conical shape.

In a case where the microphone capsule20is supported by a plurality of supporters having rotation symmetry similar to that of the supporter30B of the second embodiment, rotation symmetry need not be the same among the plurality of supporters. Further, even in a case where the plurality of supporters have the same rotation symmetry, the planar shapes of the supporters need not overlap when viewed in the central axis direction. For instance, two supporters each having two-fold rotation symmetry (i.e., line symmetry) may be disposed such that symmetry axes (axes of line symmetry) of the respective two supporters are orthogonal to each other to support the microphone capsule20. This configuration ensures the stability in supporting the microphone capsule20while enabling the two supporters to more easily undergo shear deformation, as compared with the configuration in which is used only one supporter having three-fold rotation symmetry.

There have been explained above the first through third embodiments of the present disclosure. The embodiments illustrated above may be modified as follows. (1) In the second embodiment, the plurality of holes330are disposed such that the planar shape of the supporter30B viewed in the axial direction has three-fold rotation symmetry about the axis. The plurality of holes330may be disposed such that the planar shape has four- or more-fold rotation symmetry. In short, the plurality holes330are disposed in N- or more-fold rotation symmetry. Here, N is a natural number greater than or equal to 3. This configuration enables the supporter to more easily undergo local shear deformation while enabling the electroacoustic transducer to be supported without being inclined, by keeping the symmetry of the supporter as a whole at N-fold rotation symmetry about the axis of the inverted truncated conical shape. The supporter30B of the second embodiment has the planar shape illustrated inFIG. 3. The supporter30B may have the planar shape of any of the supporters of cases2-10illustrated above. This is because, as long as the holes that extend in the circumferential direction are formed on the circumferential wall, it is considered that shear deformation in the circumferential direction occurs more easily, as compared with the supporter30A of the first embodiment.

(2) In place of the holes330of the second embodiment, there may be formed third portions each having a thickness smaller than that of other portion of the supporter30B. This configuration also enables the circumferential wall of the supporter having the inverted truncated conical shape to easily undergo shear deformation, as compared with a configuration in which the supporter has neither the holes330(as described in the first embodiment) nor the third portions each as the portion having a thickness smaller than that of other portion of the supporter. Thus, the effect of reducing the noise can be enhanced. The supporter30B of the second embodiment has the hollow, inverted truncated conical shape. Instead, the supporter30B of the second embodiment may be shaped like a disc, for instance. The disc-like supporter may have the holes330or the third portions330similar to those in the second embodiment.

(3) The supporter in each embodiment is formed of an elastic material such as fluororubber. Thus, the supporter has elasticity owing to material. The supporter may be formed of resin. This is because the area of the supporter that undergoes shear deformation can be ensured owing to shape if the supporter has the holes as in the second embodiment or the supporter has the third portions in place of the holes as in the modification (1).

(4) Though the principle of the present disclosure is applied to the handheld microphone in the illustrated embodiments, it may be applicable to stationary microphones because the sound signal that includes the noise arising from the vibration transmitted via the housing is output from the electroacoustic transducer in the stationary microphones. The principle of the present disclosure may be applied to speakers, thereby making it possible to reduce noise emitted due to transmission of the vibration to the electroacoustic transducer via the housing of the speakers. In short, the vibration is prevented from being transmitted to the electroacoustic transducer via the housing and the noise due to the vibration is thereby prevented from being generated in the electroacoustic transducer device including the housing and the electroacoustic transducer, by providing the supporter formed in the inverted truncated conical shape and including the first portion held in contact with the electroacoustic transducer and the second portion held in contact with the housing, the first portion and the second portion being positioned at mutually different height levels in the axial direction.
