Microphone assembly and a portable electronic device using the microphone assembly

A microphone assembly (10) using in a portable electronic device includes a fixing component (12) detachably fixed to a housing (30) of the portable electronic device, and a main microphone body (14) latched to the fixing component (12). The microphone assembly (10) may be conveniently detached and increases reliability of the housing (30).

BACKGROUND

1. Field of the Invention

The present invention relates to a microphone assembly and a portable electronic device using the microphone assembly.

2. Description of related art

Currently, electronic devices, such as mobile phones and personal computers are often equipped with microphones. Users can transfer sound information through the microphone to receivers.

In mobile phones, the microphone is usually accommodated in the phone housing. A receiving slot is defined in the housing. The microphone can be fixed in the receiving slot by bonding or welding methods.

When the microphone is damaged, the damaged microphone needs to be removed from the housing to be replaced with a new microphone. If the shape or dimension of the new microphone is different from that of the damaged microphone, the receiving slot also needs to be changed for fitting the new microphone. However, such process is complicated and may cause damage to an inner structure of the housing thereby reducing the housing's reliability.

Therefore, there is room for improvement within the art.

DETAILED DESCRIPTION OF THE EXEMPLARY EMBODIMENTS

FIGS. 1 and 2show two different views of a microphone assembly10and a housing30for a mobile phone. The housing30includes a bottom plate31. The bottom plate31has a receiving chamber32adjacent to an end of the bottom plate31. The receiving chamber32includes a first sidewall322and a second sidewall323facing each other. The second sidewall323defines two grooves324, and the first sidewall322defines two notches326.

The microphone assembly10includes a fixing component12and a main microphone body14. The fixing component12can be made of flexible material, e.g., rubber.

The fixing component12includes a connecting arm122and two protruding portions124extending from ends of the connecting arm122. The protruding portions124and connecting arm122define a receiving opening126. Two end walls1262adjacent to the receiving opening126have two blocks1264respectively positioned thereon. The connecting arm122includes two latching portions1222positioned on an opposite side thereof facing away from the protruding portions124. The latching portions1222can be respectively latched into the notches326. Two clasps1242are respectively positioned on an end of the protruding portions124orienting away from the connecting arm122. The clasps1242can be respectively latched in the grooves324.

The main microphone body14is substantially rectangular, and has two hooks16respectively positioned on two opposing ends thereof. Each free end of the hooks16is flexible and has a latching surface162and an inclined surface164positioned at an opposite side to the latching surface162. When a force is applied to the inclined surface164, the hooks16undergo elastic deformation. When the force is removed, each of the hooks16may recover its original state.

Referring toFIG. 3, the fixing component12is fixed in the receiving chamber32with the latching portions1222and clasps1242respectively engaging in the notches326and grooves324. Furthermore, the fixing component12and the second sidewall323enclose a concave slot (not shown). Secondly, the main microphone body14is aligned with the concave slot and pressed downward. Therefore, the blocks1264respectively resist the inclined surface164of the hooks16, and each of the hooks16undergo elastic deformation to latch with the blocks1264.

When the microphone assembly10is to be disassembled, a force is applied to the fixing component12and the latching portions1222and clasps1242respectively deviate from the notches326and grooves324, so the fixing component12can be removed from the receiving chamber32. Furthermore, the hooks16deviate from the blocks1264to remove the main microphone body14from the receiving chamber32.

It is to be understood that the fixing component12can be a closed frame structure defined an opening. The main microphone body14can be fixed in the opening. By having the microphone assembly include the fixing component12and the main microphone body12, microphone bodies can be replaced with microphone bodies of different sizes without affecting the structure of bottom plate21.

It is to be understood that the latching portions1222have the same structure as the clasps1242. The latching portions1222and the clasps1242can be viewed as a block fixing component. Meanwhile, the notches326can also be taken as the grooves324.
