Abstract

The invention discloses a sound output method and a terminal device. The terminal device comprises a boosting module, an audio amplification module and an exciter. The boosting module is electricallyconnected with the audio amplification module and the audio amplification module is electrically connected with the exciter. When the terminal device is in an output sound state, According to the corresponding relationship between the noise volume value and the output voltage value of the booster module, the output voltage of the booster module is adjusted to be the output voltage value corresponding to the noise volume value of the current environment, and when the exciter is in an on state, the exciter outputs sound with the volume value corresponding to the output voltage value. The invention can reduce or even avoid the electric sound perception of the user, and improve the experience of the user in using the sound output function.

Description

technical field

[0001] The present invention relates to the technical field of communication, in particular to a sound output method and a terminal device. Background technique

[0002] The traditional handset structure generally needs to open holes on the glass cover of the terminal device to function. However, with the advent of the era of mobile intelligence, full-screen display screens (referred to as full screens) are more valued by consumers. With the expansion of the ratio, the bottom of the glass cover has been basically occupied by the display screen, and there is no longer the condition for opening holes. Therefore, the traditional earpiece structure is no longer suitable for terminal devices with full screens.

[0003] In related technologies, in order to cope with this situation, an exciter is generally used to replace the traditional receiver to realize the earpiece function. Its working principle is to transmit sound through vibration, which can meet the demand...
