<p>A communication device is disclosed by the present invention. The device includes an upper housing and a bottom housing connected to each other, a master Printed Circuit Board (PCB) for realizing a communication function, a speaker and a keypad assembly. The master PCB board is arranged on the bottom housing, wherein the upper housing includes a front housing and a front cover, the keypad assembly is arranged between the front housing and the front cover; the speaker is arranged under the front housing, the keypad assembly is connected to the master PCB board by a flexible circuit board which passes through the front housing; voice spreading holes connecting to the front cavity of the speaker are correspondingly arranged on the front cover, the keypad assembly and the front housing; the joints among the front housing, the keypad assembly, the front cover and the speaker are waterproof. Application of the front housing by the present invention, the keypad PCB board is separated from the speaker, and it is convenient for the waterproof process. The design of timely drain on the front housing can prevent the water in the front cavity of the speaker from a longtime accumulation, which influences the voice effect. At the same time, application of the waterproofing manner such as traditional mesh fabric waterproofing can pre-performance of the whole device, and reaching the waterproofing level of IP67 level after verified.</p> |
