Embodiment Construction

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and in conjunction with specific embodiments.

[0022] Before describing the present invention, a brief description of the principle of a mobile phone for realizing a call is made first. like figure 2 As shown, it shows the principle of a mobile phone with a sidetone function to realize a call. The so-called side tone refers to: if people speak in the wilderness, they will feel that the surrounding is very empty, this is because the voice of the people in the wilderness cannot form an effective echo; if people are speaking in a room, the walls, furniture , decorations, etc. will feed back the sound to the speaker, which sounds more natural. In order to enable the user to make a call in any place, the mobile phone will transmit the voice information received by the microphone to the receiver of the mobile phone, which produces the same effect as the indoor echo....

Abstract

The invention discloses a method and a device for realizing a hearing aid function at a mobile terminal. The mobile terminal comprises a center processor unit, a sidetone audio frequency amplifier, a voice audio frequency amplifier and a codec. The realizing method comprises the following steps: 1. a parameter setting unit responses to an input setting operation and generates a corresponding setup parameter according to the input setting operation; 2. the center processor unit sets a corresponding hearing aid parameter for the sidetone audio frequency amplifier and the voice audio frequency amplifier according to the setup parameter in the step 1 and switches an audio frequency channel to an earphone channel; 3. the sidetone audio frequency amplifier and the voice audio frequency amplifier process the exterior voice according to the hearing aid parameter under the control of the center processor unit and then the center processor unit sends the processed exterior voice to an earphone by the earphone channel. The realizing device comprises the center processor unit, the sidetone audio frequency amplifier, the voice audio frequency amplifier, the parameter setting unit and the earphone. The method and the device of the invention realize the hearing aid function at the mobile terminal.

Description

technical field [0001] The present invention relates to the field of mobile communications, and in particular, to a method and device for realizing a hearing aid function on a mobile terminal. Background technique [0002] With the maturity and development of mobile communication technology, mobile terminals (mobile phones) have more and more functions, such as mobile phone audio, mobile video, mobile Internet access, etc. High-efficiency social needs are well received by users. People have gradually regarded mobile phones as one of the necessities of life. At the same time, they also hope that mobile phones will develop in the direction of integrating more and more powerful functions. [0003] On the other hand, people with hearing impairment currently cannot hear the small sounds of the outside world due to their own limitations. Most of them must rely on hearing aids to amplify the voice information before they can communicate effectively with others. Therefore, hearing a...
