Mobile terminal

Abstract

The present invention provides a mobile terminal, comprising a back shell, a horn and a front shell, wherein a first sealing body is arranged around the end face of the horn, a groove is formed in the inner wall of the back shell, and at least two positioning necks are formed in the inner wall of the front shell; the horn is arranged in the groove of the back shell, the front shell is hermetically covered on the back shell, and the positioning necks of the front shell and the end face edges of the horn are hermetically clamped by the first sealing body, so that a back sound cavity formed among the inner wall of the groove of the back shell, the side wall of the horn and the inner wall of the front shell is separated from a front sound cavity formed between the end face of the horn and the inner wall of the front shell; and a sound outlet hole is formed in the bottom of the front shell, and a sound outlet channel is formed between the front sound cavity and the sound outlet hole. Therefore, the front and back sound cavities do not need to be sealed by dispensing to separate from each other. Accordingly, if the horn is damaged, only the horn needs to be changed, and thus the maintenance cost is lower.

Description

technical field [0001] The present invention relates to the technical field of terminals, in particular to a mobile terminal. Background technique [0002] Generally, there are two ways to output the sound from the speaker of the terminal: the back side sounding way and the side sounding way; compared with the side sounding way, the back sounding way is prone to affect the sound effect when the terminal is placed to block the sound hole. Therefore, the user The contralateral pronunciation method is becoming more and more popular, and the proportion of terminals adopting the side pronunciation method in the terminal market is also increasing. [0003] figure 1 It is a partial left-view structure schematic diagram of a traditional side-talking device. Such as figure 1 As shown, in the traditional side-firing technology, in order to realize the sound output channel A of the front sound cavity indicated by the arrow, the lower edge of the end face of the speaker B cannot be p...

AI Technical Summary

Problems solved by technology

like figure 1 As shown, in the traditional side-firing technology, in order to realize the sound output channel A of the front sound cavity indicated by the arrow, the lower edge of the end face of the speaker B cannot be provided with foam, and there is usually a gap D between the speaker B and the front shell C, resulting in There is continuity between the front sound chamber E and the rear sound chamber F; in order to seal the gap D between the speaker B and the front shell C to isolate the front and rear sound chambers, usually at the midpoint of the gap D between the speaker B and the front shell C Glue, so that the speaker B and the front shell C become an inseparable whole

It can be seen that if the horn is damaged, the horn and the front shell need to be replaced, so the maintenance cost is relatively high
