specific Embodiment

[0038] Such as figure 1 As shown, the present invention provides a method for adaptively adjusting the volume of a call terminal. The call terminal is provided with a distance sensor at the position of the pickup. Specifically, the distance sensor can be set in or adjacent to the installation position of the pickup; Distance sensor, also known as displacement sensor (such as optical displacement sensor, linear proximity sensor, ultrasonic displacement sensor, etc.), uses components to detect the physical change of the object, and measures the distance from the sensor to the object by converting the change into a distance. Machines with distance displacement. There are related applications in mobile phones, for example, to prevent misoperation of the face on the touch screen when making a phone call.

[0039] The methods include:

[0040] Step S1: When using the calling terminal to make a call, collect a first distance value from the user's face through the distance sensor. ...

Abstract

The invention provides a call terminal and an adaptive volume adjustment method and system thereof. The method comprises the following steps: when the call terminal is used for making a call, acquiring a value of a first distance between the call terminal and the face of a user through a distance sensor of the call terminal; calculating a value of a second distance between a sound pickup and a sound source according to a predetermined calculation rule and the acquired first distance value; and correspondingly adjusting a gain of the sound pickup according to the change of the second distance value. The phenomena that an answering person cannot hear due to an over low volume, or damage is caused to ears of the answering person due to an over high volume, and the like since the distance between the user and the sound pickup varies under different postures of the user are avoided, thereby improving the call experience of the user.

Description

technical field [0001] The invention relates to the technical field of call terminals, in particular to a call terminal and a volume adaptive adjustment method and system thereof. Background technique [0002] The reason why a mobile phone can make a call is because there is a huge system behind it supporting it. In my country, the analog mobile phone belongs to the analog network or ETACS system, and the GSM digital mobile phone belongs to the GSM digital network or the GSM system. Each channel of the analog ETACS system has a different frequency. When the base station sends a signal to instruct a mobile phone to transmit a specified frequency to access the Internet, the user occupies this channel, and other users cannot occupy the same channel; GSM system The TDMA site selection method is adopted. The channel of the same frequency is divided into 8 time slots, which can be occupied by different users at different time periods. The signals between users are distinguished b...
