Embodiment Construction

[0044] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0045] see Figure 1-6 , the volume gain adaptive device provided by the present invention includes

[0046] The sound transmission device is used to receive and output the external sound signal S1;

[0047] The volume gain control device is used to receive the sound signal S1 output by the sound transmission device and process the sound signal S1 to obtain and output the second sound signal S2;

[0048] A sound receiving device, configured to receive the second sound signal S2 output by the volume gain control device;

[0049] When the sound signal S1 is greater than -15 decibels and less than 0 decibels, the sound signal S1 is attenuated to obtain a second sound signal S2, and output to the sound receiving device;

[0050] When the sound signal S1 is less than -15 decibels and greater than -40 decibels, the sound signal S1 is increased to obtain a ...

Abstract

The invention relates to an adaptive volume gain device and an adaptive volume gain method. The device comprises a voice transmitting device, a volume gain control device and a voice receiving device, wherein the voice transmitting device is used for receiving a voice signal S1 from outside and outputting the voice signal S1; the volume gain control device is used for receiving the voice signal S1 output by the voice transmitting device, processing the voice signal S1 to obtain a second voice signal S2 and outputting the second voice signal S2; the voice receiving device is used for receiving the second voice signal S2 output by the volume gain control device; and when the voice signal S1 is more than -15 decibels and less than 0 decibel, the voice signal S1 is attenuated to obtain the second voice signal S2 and the second voice signal S2 is output to the voice receiving device. Through the device and the method, the condition that the voice signal received by a voice signal receiver is unstable can be automatically improved according to the magnitude of the voice signal sent by a voice sender.

Description

technical field [0001] The invention relates to a volume gain adaptive device and method. Background technique [0002] With the development of wireless communication, there are more and more mobile phone users around the world. The requirements of users for mobile phones are not only satisfied with calls, but also to be able to provide high-quality call effects. Especially the current development of mobile multimedia technology, the mobile phone Call quality is even more important. [0003] At present, when a user makes a call with a mobile phone, because the signal is good and bad, sometimes big and small, or the answerer moves the phone away from or close to the head, the voice of the answerer will be loud and soft, which will affect the quality of the call. . [0004] Therefore, it is necessary to provide a volume gain adaptive device and method, which can automatically adjust the size of the sound received by the receiver according to the size of the transmitted sound...
