## Background
BACKGROUND
1. Technical Field
The present disclosure relates to a speaker module, and particularly relates to a speaker module used in an electronic device.
2. Description of Related Art
Electronic devices, such as a mobile phone, include a speaker module for playing sound. The speaker shape, which may be rectangular or oval, always have pins arranged symmetrically on a same side of the speaker module, such as from left to right or from up to down. The space for mounting speaker module inside the electronic device is very limited, thereby the speaker module is compact and the distance between pins is close. The pins are configured to be soldered to pads set on a printed circuit board (PCB) of the electronic device. Since the distances between the pads and the pins are close, dislocation and misalignments between pins and pads are common. Thus, errors in assembling the speaker module easily occur and the performance and the reliability of the speaker module may be adversely affected.

DETAILED DESCRIPTION
The present disclosure, including the accompanying drawings, is illustrated by way of examples and not by way of limitation. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean “at least one”.
FIG. 1 shows a speaker module 100 of an exemplary embodiment of the present disclosure. The speaker module 100 is used for portable electronic devices, such as mobile phones, personal digital assistants, and tablet computers, for playing sound.
FIG. 2 shows the speaker module 100 including a bracket 10, a speaker 20 held by the bracket 10, and a pair of pins 30 for assembling the speaker module 100 to a PCB 200 (shown in FIG. 4) and electrically connecting the speaker 20 with the PCB 200.
The speaker module 100 is cubic in shape. The bracket 10 includes a top surface 11 and a peripheral wall 12 surrounding the top surface 11. The peripheral wall 12 includes two oppositely positioned sidewalls, and defines two receiving grooves 142 towards the ends of each sidewall. That is, the bracket 10 has four receiving grooves 142 arranged approximately on four corners of the peripheral wall 12. Each receiving groove 142 is recessed towards the top surface 11 of the bracket 10.
The speaker 20 is received in and held by the bracket 10, and includes a diaphragm 201 exposed through an opening defined in the top surface 11, and a bottom surface 202 positioned opposite to the diaphragm 201. The bottom surface 202 faces the PCB 200 when the speaker module 100 is assembled to the PCB 200. The peripheral wall 12 protrudes a predetermined height from the bottom surface 202.
FIG. 3 shows the pins 30 arranged diagonally on the bracket 10 and configured for being soldered to pads 220 of the PCB 200 to electrically connecting the speaker 20 with the PCB 200. During manufacturing, the pins 30 are easily attached to the pads 220 of the PCB 200 since the distance between the two pins 30 is substantial. The size of the speaker module 100 is still compact since only the manner of arrangement of the pins 30 is changed.
In addition, when the pins 30 are assembled to the speaker module 100, the speaker module 100 can be installed with a rotatable tool (not labeled), the two pins 30 can be assembled in one orientation, or the tool rotated through 180 degrees and the two pins 30 assembled in a reverse orientation.
Each pin 30 is a protruding portion of a conductive bent elastic metal element 32. One end of the metal element 32 is received in the receiving groove 142, while the other end extends towards the corner of the peripheral wall. The end portion of each metal element 32 near the corner of the peripheral wall 12 is bent and projects a predetermined height from the peripheral wall 12, and thus forming the pin 30. The pins 30 support the speaker module 100 at a predetermined height above the PCB 200, which facilitates the dissipation of heat generated by the speaker module 100.
The pins 30 can also be pads arranged on two diagonally-opposite corners of the peripheral wall 12. Due to the peripheral wall 12 projecting from the bottom surface 202, when the speaker module 100 is assembled on the PCB 200, the peripheral wall 12 supports the bottom surface 202 at a certain height above the PCB 200, which facilitates heat dissipation from the speaker module 100.
The pins 30 can also be needle shaped pins projecting from the corners of the peripheral wall 12. The pins 30 are inserted through the pads 220 of the PCB 200 and are soldered on the PCB 200, which can firmly assemble the speaker modules 100 more firmly on the PCB 200.
The speaker module 100 can also be oval in shape. The pins 30 are arranged diagonally on the peripheral wall 12 across the oval.
The speaker module 100 includes two pins 30 on diagonal corners, thus the distance between the pins 30 is enlarged to facilitate assembly of the speaker module 100 to the PCB 200, while the size of the speaker module 100 remains compact. Therefore, the speaker module 100 has advantages in convenience for assembly, less mistakes when assembly, and good reliability after being assembled.
Even though numerous characteristics and advantages of the embodiments have been set forth in the foregoing description, together with details of the structure and function of the embodiments, the present disclosure is illustrative only, and changes may be made in detail, especially in the matters of shape, size, and arrangement of parts within the principles of the embodiments to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
