Embodiment Construction

[0009] The technical solutions in the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0010] refer to figure 1 As shown, it is a hardware configuration diagram of the automatic volume adjustment device 10 in one embodiment. The automatic volume adjustment device 10 is applied to some electronic devices such as mobile phones, fixed phones, computers, etc. that can realize two-party voice communication, and automatically adjusts the volume of the other party's voice output by the electronic device according to the ambient noise during the two-party conversation. In this embodiment, the automatic volume adjustment device 10 is composed of the following parts: a storage unit 150 , an input unit 120 , an analog / digital conversion unit 130 , and a processing unit 100 .

[0011] The storage unit 150 is used to store a comparison table (not shown) of noise intensity and volume adjustment, the noise intensity is t...

Abstract

The invention discloses an automatic volume adjustment method. The method comprises the following steps of: recording external sound by an input unit; converting the external sound into a digital signal; identifying whether the digital signal is ambient noise or user language; if the digital signal is the ambient noise, judging the intensity of the ambient noise; acquiring volume adjustment corresponding to the intensity of the ambient noise from a comparison table of noise intensity and volume adjustment, wherein the comparison table defines that the volume of received sound of the other party of a call is turned up along with the increase of the intensity of the ambient noise; and adjusting the volume of the received sound of the other party of the call according to the acquired volume and outputting the sound. The invention also provides an automatic volume adjustment device. By using the automatic volume adjustment device and the automatic volume adjustment method of the invention, a user can receive the audio frequency of the other party of the call without manually adjusting the volume.

Description

technical field [0001] The invention relates to a device and a method for automatically adjusting volume, in particular to a device and a method which can recognize environmental noise and automatically adjust the volume according to the magnitude of the noise. Background technique [0002] In modern life, mobile phones, landline phones, computers and other electronic devices that can realize voice communication between the two parties generally have to manually adjust the output volume of the electronic devices. However, there are many defects in this method of manually adjusting the volume. . For example, when the user is in a noisy environment, in order to hear the voice of the other party clearly, he often needs to turn up the volume, and then when entering a quieter environment, he will feel uncomfortable because of the high volume. The volume needs to be turned down again. For another example, when the user needs to adjust the volume in some special environments, suc...
