Embodiment Construction

[0016] Such as figure 1 Shown is the operating environment diagram of the volume adjustment system of the present invention. In this embodiment, the volume adjustment system 10 runs in the mobile phone 100 and is used to adjust the volume of the earpiece 20 of the mobile phone 100 . In this embodiment, the mobile phone 100 further includes a microphone 30 , an analog-to-digital converter (Analog-Digital Converter) 40 , a memory 50 and a processor 60 .

[0017] In this embodiment, the microphone 30 is the rear microphone of the mobile phone 100, and is used to pick up the noise of the background environment of the mobile phone 100 and convert it into an analog quantity of voltage when the mobile phone 100 is in a call state. The analog-to-digital converter 40 collects the analog voltage of the ambient noise from the microphone 30 and converts it into a digital voltage. In this embodiment, the volume adjustment system 10 adjusts the volume of the earpiece 20 according to the v...

Abstract

A mobile phone receiver volume adjusting method comprises the steps of presetting a standard volume adjusting table which defines different noise voltage value ranges to correspond to different volume levels; reading a voltage value of the environmental noise acquired by an analog-to-digital converter of a mobile phone according to a preset reading frequency, wherein the analog-to-digital converter acquires the analog quantity of the voltage of the environmental noise from a microphone of the mobile phone and transforms the analog quantity into the digital quantity of the voltage; calculating an average voltage value of N environmental noise voltage values after the N environmental noise voltage values are read, and taking the obtained average voltage value as a voltage reference value; when M continuously obtained voltage reference values are all within a noise voltage value range defined by the standard volume adjusting table, adjusting the volume of a receiver of the mobile phone as the volume level corresponding to the noise voltage value range. The mobile phone receiver volume adjusting system and the mobile phone receiver volume adjusting method of the present invention enable the volume of the receiver of the mobile phone to be adjusted automatically according to the environmental noise voltage value.

Description

technical field [0001] The invention relates to a volume adjustment system and method of a mobile phone earpiece. Background technique [0002] Mobile phone users usually need to constantly adjust the volume of the earpiece during a call. For example, if the ambient noise is very loud, the user usually manually turns up the volume of the earpiece, and when the ambient noise becomes small, the user manually turns down the volume of the earpiece to adjust the earpiece volume to a level suitable for calls. The disadvantage of this receiver volume adjustment method is that the user needs to manually adjust it every time, which is inconvenient for the user to use the mobile phone. Contents of the invention [0003] In view of the above, it is necessary to provide a handset volume adjustment system for automatically adjusting the volume of the handset. [0004] In view of the above, it is necessary to provide a method for adjusting the volume of the earpiece of the mobile phon...
