Such an electronic device may include various elements, for example a sound output module, camera module, and battery that provide various functions.
However, in order to improve portability, there is a desire for an electronic device having a reduced thickness. The reduced thickness makes it difficult in recent electronic devices to secure mounting space of elements to provide the foregoing various functions. Therefore, necessity to provide an electronic device having a reduced thickness while including various elements is desired.
Currently, in order to provide various audio performances, a recent electronic device includes a sound output module (e.g., a speaker module). For example, in a mobile phone (e.g., a feature phone or a smart phone), portable music player (e.g., an MP3 player or a Samsung Galaxy PlayerTM), portable camera (e.g., a Samsung Galaxy CameraTM), and tablet PC (e.g., a Samsung Galaxy TabTM, a Samsung Galaxy NoteTM), a sound output module provides various audio reproduction functions as well as a speaker phone function.
Particularly, the sound output module needs resonant space enough to secure a performance of an audio performance, particularly medium and low frequency band sound. However, as an electronic device has a reduced thickness, it is difficult to secure resonant space of a sound output module of the electronic device.
Accordingly, an electronic device including a sound output module that may secure resonant space of a sound output module and a housing for the electronic device is desired.
The above information is presented as background information only to assist with an understanding of the present disclosure. No determination has been made, and no assertion is made, as to whether any of the above might be applicable as prior art with regard to the present disclosure.

An electronic device according to an embodiment of the present disclosure includes a sound output module and may be a mobile communication electronic device, smart phone, Personal Digital Assistant (PDA), tablet Personnel Computer (PC), hand-held PC, and portable multimedia player (PMP).
As described above, in the electronic device, in order to secure an audio performance, particularly a performance of medium and low frequency band sound, a sound output module (e.g., a speaker module) needs resonant space. However, as the electronic device has a reduced thickness, it is difficult for the electronic device to secure resonant space of the sound output module (speaker module).
Hereinafter, various embodiments of the present disclosure suggest a configuration that may solve such a problem.
FIGS. 1A and 1B are a perspective view and an exploded perspective view illustrating a general electronic device according to an embodiment of the present disclosure.
Referring to FIGS. 1A and 1B, an electronic device 1 may be formed in a quadrangular bar type, as illustrated in FIG. 1A. Such an electronic device 1 may include a front case 10, rear case 20, and battery cover 30, as shown in FIG. 1B. In the front case 10 of the electronic device 1, a display unit (not illustrated) and a protective window (not illustrated) may be mounted. For this, in the front case 10, a first opening portion 11 that exposes the display unit and the protective window may be formed. Further, in the front case 10, a receiver hole 12 and a home key hole 14 may be further formed. The rear case 20 may be coupled to the front case 10. In the rear case 20, a second opening portion 21 that mounts a battery and a first speaker hole 31a that emits a sound signal to the outside may be formed.
The battery cover 30 is detachably coupled to the rear case 20 and prevents a battery (not illustrated) from separating. In the battery cover 30, a second speaker hole 31b that emits a sound signal to the outside may be formed. The second speaker hole 31b may formed to correspond to the first speaker hole 31a. 
FIG. 2A is an exploded perspective view of an electronic device according to an embodiment of the present disclosure, and FIG. 2B is a cross-sectional view taken along line A-A′ of the electronic device of FIG. 2A according to an embodiment of the present disclosure.
Referring to FIGS. 2A and 2B, the electronic device according to the present embodiment may be formed in a quadrangular bar type. However, various embodiments of the present disclosure are not limited thereto. For example, the electronic device according to the present embodiment may be formed in a folder type and a slide type. Such an electronic device may include a first case 100, second case 200, cover case 300, sound output module 400, support member 500, and battery 600. The first case 100, second case 200, cover case 300, and sound output module 400 may be coupled through at least one of mechanical coupling (e.g., screw coupling and hook coupling), chemical coupling (e.g., one-part bonding liquid and two-part bonding liquid), a thermal fusion-bonding method, a supersonic wave fusion-bonding method, and an epoxy hardening method.
In the first case 100, a display unit 130 may be mounted. Further, in the first case 100, a protective window 150 to protect the display unit 130 may be mounted. Such a first case 100 may become a front case of the electronic device. A first case 100 according to another embodiment of the present disclosure is a display module and may have a structure formed in a module. In the first case 100, an opening 110 that enables the display unit 130 to be exposed to the outside, a receiver hole 101 to discharge sound of a communication speaker (not illustrated) to the outside, and a home key hole 102 that may insert a physically formed home key (not illustrated) may be formed.
The second case 200 may be coupled to the first case 100. Further, the second case 200 may be coupled to the detachable cover case 300. That is, the second case 200 may be disposed between the first case 100 and the cover case 300. The second case 200 may be referred to a rear case, rear cover, rear cover case, back cover, back case, or rear housing of the electronic device. The second case 200 according to the present embodiment includes a mounting area of the battery 600 in an opening 210 and a mounting area of the sound output module 400.
The cover case 300 may be detachably fastened to the second case 200 and prevents the battery 600 from separating. That is, the cover case 300 may be a battery cover. The cover case 300 may have a speaker hole 310 to emit an audio signal output from the sound output module 400 to the outside. FIGS. 2A and 2B illustrate that the cover case 300 covers the entire second case 200, but various embodiments of the present disclosure are not limited thereto. For example, the cover case 300 may be formed to cover only a mounting area of the battery 600 of the second case 200 or only a mounting area of the battery 600 and the sound output module 400.
The sound output module 400 outputs an audio signal and may be formed with a first sound output module 400a (i.e., a carrier) and a second sound output module 400b (i.e., a speaker). In this case, internal space of the first sound output module 400a is used as resonant space of the second sound output module 400b (i.e., speaker). The sound output module 400 may be referred to as a speaker module or a sound carrier module. The sound output module 400 may be fastened to the second case 200. Particularly, when the battery 600 is mounted, the sound output module 400 according to the present embodiment may be fastened to the second case 200 so that one side surface contacts with the battery 600 or is adjacent to the battery 600. Specifically, the sound output module 400 may form one side wall of mounting space to mount the battery 600. That is, mounting space of the sound output module 400 may be formed so that at least a portion of one side surface of the battery 600 is exposed at mounting space of the sound output module 400. In this way, in the present embodiment, a structure (e.g., a portion of the second case 200) does not exist between the sound output module 400 and the battery 600. That is, the battery 600 may be received at space defined according to the second case 200 and the sound output module 400. Therefore, in the present embodiment, resonant space of the sound output module 400 may be fully secured in a length direction (a Y-axis direction).
Further, the sound output module 400 includes a first surface (e.g., an upper surface) facing the cover case 300, and the first surface may contact with the cover case 300 or may be adjacent to the cover case 300. For this, mounting space of the sound output module 400 included in the second case 200 may be formed so that at least a portion of the first surface is exposed from the cover case 300. That is, a structure (e.g., a portion of the second case 200) does not exist between the first surface of the sound output module 400 and the cover case 300. Therefore, in the present embodiment, resonant space of the sound output module 400 may be extended in a thickness direction (Z-axis direction). The sound output module 400 further includes a second surface facing the opposite side of the cover case 300, and at least a partial area of the second surface may contact with the first case 100 or may be adjacent to the first case 100. In this case, another partial area of the second surface of the sound output module 400 may contact with the support member 500 or may be adjacent to the support member 500.
Such a sound output module 400 may be coupled to at least one of the second case 200 and the support member 500 through at least one of mechanical coupling (e.g., screw coupling or hook coupling), chemical coupling (e.g., one-part bonding liquid, two-part bonding liquid), a thermal fusion-bonding method, a supersonic wave fusion-bonding method, and an epoxy hardening method. Thereby, in the present embodiment, strength of the second case 200 that may be weakened by removing the second case 200 between the battery 600 and the sound output module 400 may be reinforced.
The sound output module 400 may occupy a volume of the entire electronic device, for example a volume of about 5%, 10%, 15%, 20%, 25%, 30%, 35%, or 40% or a volume within a range which two values of previously listed values are determined as a maximum value and a minimum value. For example, the sound output module 400 may occupy a volume of about 10-40% of the entire electronic device. However, various embodiments of the present disclosure are not limited thereto and an occupying volume of the sound output module 400 may be variously changed according to a specification of the electron device.
The support member 500 is positioned between the first case 100 and the second case 200 to maintain strength (or rigidity) of the electronic device. For this, it is preferable that the support member 500 may be made of a metal material (e.g., magnesium, aluminum, stainless). Such a support member 500 may become a bracket. The sound output module 400 may be mounted on the support member 500. That is, the support member 500 may support the sound output module 400.
Further, in the support member 500, a protrusion 501 that supports the battery 600 is formed. The protrusion 501 may have a height lower than that of the battery 600. For example, the protrusion 501 supports the battery 600, and when an impact occurs in a Y-axis direction, the protrusion 501 may be formed in a minimum height that may prevent damage in which the battery 600 gives to the sound output module 400. For example, the protrusion 501 may have a height of about 30% to 60% (e.g., 30%, 35%, 40%, 45%, 50%, 55%, or 60%) of a height of the battery 600. However, various embodiments of the present disclosure are not limited thereto and a height of the protrusion 501 may be variously formed according to a designer's intention.
Referring to a cross-sectional view of FIG. 2B, in an electronic device according to the present embodiment, because a structure (e.g., a portion of the second case 200) does not exist between the sound output module 400 and the cover case 300 and between the sound output module 400 and the battery 600, resonant space of the sound output module 400 may be fully secured by a size of reference numeral 700. By securing the resonant space, the electronic device of the present embodiment may have an improved performance of a speaker.
Further, in a description in relation to FIG. 2B, it has been described that resonant space of the sound output module 400 is secured in a Y-axis direction and a Z-axis direction, but when resonant space of the sound output module 400 is extended only in a Y-axis direction, in the present embodiment, the electronic device may have a small thickness by a removed thickness of the second case 200. That is, the electronic device of the present embodiment may secure a performance of a speaker while having a small thickness.
Although not illustrated in FIGS. 2A and 2B, the electronic device may further include a printed circuit board in which a plurality of electronic elements are mounted, camera module to photograph an image or a moving picture, vibration motor to generate a vibration, and antenna to transmit and receive a wireless signal.
FIG. 3A is a cross-sectional view illustrating an electronic device according to another embodiment of the present disclosure.
Referring to FIG. 3A, the electronic device according to the present embodiment may include a first case 100, second case 200, cover case 300, sound output module 400, support member 500, and battery 600. The first case 100 may house a display unit 130 and a protective window 150.
The support member 500 may be formed with a first support member 500a positioned at a bottom surface of the battery 600 and a second support member 500b positioned at a bottom surface of the sound output module 400. The electronic device according to the present embodiment has the same configuration as that of the electronic device according to the foregoing embodiment of the present disclosure, except for such a difference. Therefore, a detailed description of other elements of the electronic device according to the present embodiment is omitted.
FIG. 3B is a cross-sectional view illustrating an electronic device according to another embodiment of the present disclosure.
Referring to FIG. 3B, a sound output module 400 of the electronic device according to the present embodiment further includes an antenna pattern 800 at least partially housed to be adjacent to an outer side surface (e.g., a first surface facing the cover case 300). That is, in the electronic device according to the present embodiment, the sound output module 400 and the antenna pattern 800 are integrally formed. As described in relation to FIGS. 2A and 2B, in the present embodiment, in a Z-axis direction, a size of the sound output module 400 may be increased. That is, in an electronic device according to another embodiment of the present disclosure, a separation distance between the antenna pattern 800 and electronic elements increases, compared with an electronic device. Thereby, in the electronic device according to the present embodiment, an influence in which noise of electronic elements has the antenna pattern 800 may be reduced. Therefore, in the electronic device according to the present embodiment, a radiation performance of an antenna may be improved. The electronic device according to the present embodiment has the same configuration as that of the electronic device according to the foregoing various embodiments of the present disclosure, except for such a difference. Therefore, a detailed description of other elements of the electronic device according to the present embodiment is omitted.

Referring to FIG. 4A, an electronic device 410 includes the sound output module 400 according to the present embodiment. The sound output module 400 may be positioned at an upper end portion of the second case 200. In other words, mounting space of the sound output module 400 may be formed at an upper end portion of mounting space of the battery 600. In this case, the sound output module 400 may be positioned so that one side surface of the sound output module 400 contacts with the battery 600 or is adjacent to the battery 600. That is, the sound output module 400 may form an upper end side wall of mounting space of the battery 600. In this case, housing space of the sound output module 400 of the second case 200 may be closed space.

In other words, mounting space of the sound output module 400 may be formed in an upper end portion and a lower end portion of mounting space of a battery 600. In this case, one side surface of the first sound output module 400a and the second sound output module 400b may contact with one side surface of the battery 600 or may be adjacent to one side surface of the battery 600. That is, the first sound output module 400a may form an upper end side wall of mounting space of the battery 600, and the second sound output module 400b may form a lower end side wall of mounting space of the battery 600. Mounting space of the first sound output module 400a may be space of a closed form, and mounting space of the second sound output module 400b may be space of a form in which one side surface (opposite surface of the battery) is opened. However, various embodiments of the present disclosure are not limited thereto. For example, mounting space of the first sound output module 400a may be formed as space of an opened form, and mounting space of the second sound output module 400b may be formed as space of a closed form. Alternatively, mounting space of the first sound output module 400a and the second sound output module 400b may be formed as space of a closed form or space of an opened form.

Referring to FIG. 7A, an electronic device 710 includes a sound output module 400 that may be formed in various shapes. For example, the sound output module 400 may be formed in ‘U’ shape to enclose a portion of a lower end portion and the lateral side of a battery 600. That is, the sound output module 400 of FIG. 7A may form a portion of a lower end side wall and a lateral side wall of mounting space of the battery 600. When the sound output module 400 of the ‘U’ shape is positioned at an upper end portion of a second case 200, the sound output module 400 may form a portion of an upper end side wall and a lateral side wall of mounting space of the battery 600. In other words, mounting space of the sound output module 400 may be formed so that a portion of a lower end portion and a lateral portion of the battery 600 is exposed or so that a portion of an upper end portion and a lateral portion of the battery 600 is exposed.

The electronic module may be an antenna module, camera module, vibration motor module, and pen module. For example, an electronic device according to another embodiment of the present disclosure may include a first case that exposes a display unit and a second case coupled to the first case and including mounting space of a battery and an electronic module. Mounting space of the electronic module may be formed so that at least a portion of one side surface of the battery is exposed at mounting space of the electronic module.
As described above, an electronic device including a sound output module according to various embodiments of the present disclosure may effectively secure a size (or a volume) of the sound output module within given mounting space. Therefore, the electronic device may secure resonant space of a speaker and thus a configuration of the electronic device may improve a performance of the speaker.
Further, by removing a second case between the sound output module and a cover case, the electronic device may have a small thickness.
Further, in various embodiments of the present disclosure, by coupling a sound output module, first case, second case, and support member through mechanical coupling or chemical coupling, strength of the electronic device may be enhanced.
Further, when an antenna pattern is mounted at an outer side surface (a surface facing a cover case) of the sound output module, due to increase in a thickness of the sound output module, a separation distance between the antenna pattern and an electronic element relatively increases. Thereby, a radiation performance of the electronic device is improved.
While the present disclosure has been shown and described with reference to various embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present disclosure as defined by the appended claims and their equivalents.
