High bass speaker monomer and a high bass earphone structure

A high bass speaker monomer comprises a framework, a magnetic air loop component and a vibration membrane. The frame work is disposed at a central position of the frame work. A hollow structure is formed on the framework and around the magnetic air loop component. An isolation ring formed on the framework divides the hollow structure into at least one high tone region and bass region respectively located near and far away from the magnetic air loop component. The vibration membrane is disposed on the framework and covers the magnetic air loop component and the two regions. The high bass speaker monomer is disposed in a casing body to construct a high bass earphone structure. The isolation ring separates the high tone from the low tone to prevent them from mixing. Therefore, the sound of the earphone is more stable and the quality of the sound is better.

TECHNICAL FIELD OF THE INVENTION

This invention relates to a speaker, particularly to a high bass speaker monomer and a high bass earphone structure.

DESCRIPTION OF THE PRIOR ART

Generally, a conventional earphone can be divided into a moving coil type, a moving iron type, an electrostatic type and an isodynamic type according to the transduction form. The earphone can also be divided into a half-open type and a closed type according to the structure. The earphone can be divided into a plug-in type, an ear-hanging type, an in-ear type and a headband type according to the carrying form.

A conventional earphone structure mainly includes a body, an interior of which forms a chamber. A speaker is mounted in the chamber. In use, sounds coming out from the speaker spread outwards, and the spread of the sounds is around a sound source. The volume of the place located nearest the sound source is the loudest. The volume of the place where the sounds spread around is gradually down. The conventional earphone only has one sound room, i.e. the chamber, which causes the high tone and the low tone to enter the same sound room and surround and thus causes the high tone to mix with the low tone. Thus, the sound of the conventional earphone is not stable and the sound quality is not good as well.

SUMMARY OF THE INVENTION

The object of this invention is to overcome the problems of the conventional structure presented supra and provide a high bass speaker monomer and a high bass earphone structure which solve the conventional problem of the unstable sound and bad sound quality of the earphone caused by mixing the high tone with the low tone in one sound room.

To obtain the above object, the technique of this invention is described as follows:

A high bass speaker monomer in accordance with this invention comprises a framework, a magnetic air loop component and a vibration membrane. The magnetic air loop component is disposed at a central position of the framework. A hollow structure is formed on the framework and around an outer periphery of the magnetic air loop component. An isolation ring is formed on the framework. The isolation ring divides the hollow structure into at least one high tone region and at least one bass region. The high tone region is located near the magnetic air loop component. The bass region is located far away from the magnetic air loop component. The vibration membrane is disposed on the framework and covers the magnetic air loop component, the high tone region and the bass region.

Preferably, this invention further comprises a cover plate. The cover plate is fixed to the framework and disposed above the vibration membrane so that the cover plate covers the vibration membrane. A set of sound holes is formed on the cover plate.

Preferably, the set of sound holes comprises a first sound hole and a second sound hole. The first sound hole communicates with the high tone region. The second sound hole communicates with the bass region.

Preferably, a plurality of first sound holes and a plurality of second sound holes can be formed on the cover plate. The first sound holes and the second sound holes are circumferentially arranged. The second sound holes are arranged around an outer periphery of the first sound holes.

Preferably, this invention further comprises a division covet. The division cover is connected to a lower portion of the isolation ring and located below the magnetic air loop component.

A high bass earphone structure in accordance with this invention comprises a casing body and the high bass speaker monomer as aforementioned. A chamber is enclosed by an interior of the casing body. The high bass speaker monomer is mounted within the chamber.

Preferably, the casing body includes a rear casing and an annular baffle fixed to the rear casing. The annular baffle and the rear casing are combined to form the chamber. The high bass speaker monomer is embedded in an inner wall of the annular baffle.

Preferably, an annular ear cap is fixed to a surface of the annular baffle.

Preferably, the high bass speaker monomer further comprises a division cover connected to a lower portion of the isolation ring and located below the magnetic air loop component. The division cover is disposed within the chamber to divide the chamber into sound rooms for receiving sounds with different audio frequencies. The sound rooms comprise a first sound room and a second sound room. The second sound room is disposed around an outer periphery of the first sound room for surrounding the first sound room.

By comparison with the conventional structure, this invention has following advantages and effects:

1. By the isolation ring formed on the framework, the isolation ring divides the hollow structure into at least one high tone region and at least one bass region to separate the high tone from the low tone and prevent two tones from mixing together, whereby the sound of the earphone is more stable and the quality of the sound (timbre) is better.
2. By the division cover connected to the isolation ring, the division cover divides the chamber into at least two sound rooms to allow the high tone and the low tone to enter different sound rooms respectively, thereby increasing the sound quality of the earphone.
3. By arranging multiple first sound holes and second sound holes which are circumferentially arranged on the cover plate and arranging the second sound holes around an outer periphery of the first sound holes, high tones enter from the first sound holes into the first sound room evenly, and low tones enter from the second sound holes into the second sound room evenly. Therefore, the homogeneity and stability of the sound of the earphone can be increased.

The advantages of this invention over the known prior arts are more apparent to those of ordinary skilled in the art upon reading following descriptions in conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

FIGS. 1-4show a preferred embodiment of this invention which comprises a casing body10and a high bass speaker monomer20.

The high bass speaker monomer20comprises a framework21, a magnetic air loop component22and a vibration membrane23. The framework21is formed in a disc shape. A hollow opening201is defined at a central position of the framework21. The magnetic air loop component22is disposed at the central position of the framework21and located in the hollow opening201. A hollow structure is formed on the framework21and around an outer periphery of the magnetic air loop component22. An isolation ring211is formed on the framework21. The isolation ring211divides the hollow structure into at least one high tone region202and at least one bass region203. The high tone region202and the bass region203are sector-shaped grooves. The high tone region202is located near the magnetic air loop component22, whereas the bass region203is located far away from the magnetic air loop component22. The vibration membrane23is disposed on the framework21and covers the magnetic air loop component22, the high tone region202and the bass region203.

The high bass speaker monomer20further comprises a cover plate24. The cover plate24is fixed to the framework21and disposed above the vibration membrane23so that the cover plate24covers the vibration membrane23. A set of sound holes is formed on the cover plate24. In this preferred embodiment, the set of sound holes includes a first sound hole204and a second sound hole205. The first sound hole204communicates with the high tone region202. The second sound hole205communicates with the bass region203. Furthermore, a plurality of first sound holes204and a plurality of second sound holes205can be formed on the cover plate24. The first sound holes204and the second sound holes205are circumferentially arranged. The second sound holes205are arranged around an outer periphery of the first sound holes204.

A chamber101is enclosed by an interior of the casing body10. The high bass speaker monomer20is mounted within the chamber101. A division cover30is connected to a lower portion of the isolation ring211, and the division cover30is located below the magnetic air loop component22. The division cover30is disposed within the chamber101to divide the chamber101into at least two sound rooms for receiving sounds with different audio frequencies. In this preferred embodiment, a first sound room102and a second sound room103are included. The second sound room103is located around an outer periphery of the first sound room102to surround the first sound room102.

Specifically, in this preferred embodiment, the casing body10includes a rear casing11and an annular baffle12fixed to the rear casing11. The chamber101is enclosed by combining the annular baffle12with the rear casing11. The high bass speaker monomer20is embedded in an inner wall of the annular baffle12. An annular ear cap40is fixed to a surface of the annular baffle12. The annular ear cap40is in direct contact with human's ears.

In use, sounds coming out from the high bass speaker monomer20spread outwards. The spread of the sounds is around a sound source. The volume of the place located nearest the sound source is the loudest, whereas the volume of the place where the sounds spread around is gradually down. Because the first sound hole204is located nearest the sound source, the high tone enters from the first sound hole204into the first sound room102and surrounds. Because the second sound hole205is located farthest from the sound source, the low tone enters from the second sound hole205into the second sound room103and surrounds.

This invention takes advantage of at least one division cover connected to the speaker to divide the chamber into at least two sound rooms and arranges sound holes communicating with the sound rooms on the speaker, thereby allowing the high tone and the low tone to enter different sound rooms and prevent the high tone from mixing with the low tone. Therefore, the sound of the earphone is more stable and the quality of the sound is better. Further, there can be multiple first sound holes and second sound holes formed on the cover plate. The first sound holes and the second sound holes are circumferentially disposed, and the second sound holes are arranged around an outer periphery of the first sound holes whereby high tones enter from the first sound holes into the first sound room evenly and low tones enter from the second sound holes into the second sound room evenly. Therefore, the homogeneity and stability of the sound of the earphone can be increased.

While the embodiment in accordance with this invention is shown and described, it is noted that further variations and modifications may be made without departing from the scope of the invention.
