Mobile terminal and sound outlet switching method

Abstract

The invention discloses a mobile terminal and a sound outlet switching method. The mobile terminal comprises a frame body and an opening for the frame body to extend or retract. The frame body is internally provided with a sound cavity, a telephone receiver, an optical device module, and a first sound outlet and a second sound outlet which are communicated with the sound cavity, and the telephonereceiver is communicated with the sound cavity. The mobile terminal further comprises a first sound guide channel, a second sound guide channel and a telescopic mechanism. Under the driving of the telescopic mechanism, the optical device module can at least partially extend out of the opening or completely retract into the mobile terminal through the opening, so that one sound outlet is communicated with the corresponding sound guide channel, and other sound outlets are separated, and the problem that the thickness of the mobile terminal is thickened or the length of the mobile terminal is toolong due to the fact that a plurality of receivers are arranged does not need to be considered. Meanwhile, the problems of poor tone quality, small volume and the like caused by simultaneous sound output of other sound outlets are effectively avoided, and the tone quality and the volume of the sound transmitted by the sound outlets can be guaranteed under the condition that the stacking space ofthe mobile terminal is allowed.

Description

technical field [0001] The invention relates to the technical field of mobile terminals, in particular to a mobile terminal and a method for switching sound outlets. Background technique [0002] Nowadays, there are more and more double-sided screen mobile phones on the market. The design scheme of the double-sided screen mobile phone also requires that the sound can be heard from the sound outlets located on the front and back of the mobile terminal. At present, the design schemes in which the sound can be heard from the sound outlets on both sides of the mobile terminal include the following two types: the first scheme is to set two earpiece devices in the mobile terminal, and the two earpiece devices can be overlapped together. It can also be placed side by side, using the front of the two earpieces to produce sound, and the rear sound cavity is closed; the second solution is to use one earpiece, using the front and back sides of the same earpiece to produce sound at the ...

Problems solved by technology

[0003] However, in the first scheme, two earpiece devices are used, and the cost of the earpiece components is relatively high, so the cost of the mobile terminal produced by the first scheme is relatively high; in addition, the space size of the mobile terminal often does not allow Setting two earpiece devices, especially overlapping the two earpiece devices, greatly increases the thickness of the mobile terminal; and the technical solution of sharing one earpiece device on both sides of the mobile terminal, regardless of mobile needs, the mobile terminal The front sound outlet or the back sound outlet is the sound output, and the earpiece device is open to output sound, so there will be problems such as distortion and low volume, and the subjective sound quality is poor

[0004] In summary, there is a lack of a technical solution for double-sided sound output that allows stacking space and has better sound quality in the existing technical solutions.
