[0016] Please refer to Figure 1 ~ Figure 2 , figure 1 A system block diagram of the mobile phone 100 according to the first embodiment of the present invention is shown, figure 2 A schematic diagram showing the handset and microphone. The mobile phone 100 includes a microphone 30 , a filter unit 50 , an adjustment unit 70 , an earpiece 90 , an analysis unit 40 , a recording unit 60 , a detection unit 80 and a communication unit 20 . The microphone 30 is used for receiving the input audio signal Vin. When the user speaks into the microphone 30 , not only the user's voice enters the microphone 30 , but also the sound generated by the background enters the microphone 30 . Therefore, the input audio signal Vin is composed of the user audio signal Vuser and the background audio signal Vbg. In a quiet environment, when the user speaks into the microphone 30 , almost only the user's voice enters the microphone 30 . Therefore, the microphone 30 can only receive the user voice s...

Abstract

The invention relates to a mobile phone and a sound volume adjusting method thereof. The sound volume adjusting method for the mobile phone comprises the following steps: providing the frequency range of the voice signal of a user; from a microphone of the mobile phone, receiving an input sound signal which comprises a user voice signal and a background sound signal; Filtering the user voice signal in the input sound signal according to the frequency range of the voice signal of the user, so as to obtain the background sound signal; adjusting the sound volume of an output sound signal played in an earphone of the mobile phone according to the sound volume of the background sound signal.

Description

technical field [0001] The invention relates to a mobile phone and its volume adjustment method, and in particular to a mobile phone capable of automatically adjusting the volume of an output sound signal played by an earpiece and its volume adjustment method. Background technique [0002] In recent years, mobile phones have become the hottest commodities. Driven by the concept of combining high-tech development with humanization, it means that mobile phones need to be used in a humanized way. [0003] However, the environment is highly developed now, such as traffic noise, roadside construction, MRT trains, aircraft sounds, and noise caused by trains are ubiquitous, so that when using a mobile phone, it is impossible to clearly identify what the other party wants to convey through the handset due to noise interference. voice message. [0004] Therefore, how to automatically adjust the volume of the voice message to be conveyed by the earpiece is an urgently needed researc...
