[0051] In the first embodiment of the present invention, a method for processing ambient sound during a call, such as figure 1 shown, including the following specific steps:

[0052] In step S101, when the user is talking through the earphone inserted into the mobile terminal, the ambient sound signal is collected.

[0053] Specifically, step S101 is implemented in the following three situations:

[0054] When the earphone is a single-listening earphone, the microphone on the mobile terminal is used to collect the ambient sound signal;

[0055] When the earphone is an earphone with a microphone, the microphone on the mobile terminal is used to collect the ambient sound signal, or the microphone of the earphone is used to collect the ambient sound signal;

[0056] In the case that the mobile terminal has the main microphone and the auxiliary microphone at the same time, use the main microphone and / or the auxiliary microphone to collect ambient sound signals.

[0064]The second embodiment of the present invention is a method for processing ambient sound during a call. Steps S201-S202 of this embodiment are the same as steps S101-S102 of the first embodiment. The difference is that, as figure 2 As shown, the method of this embodiment also includes the following steps before step S201:

[0065] Step S200, before collecting environmental sound signals, acquire the location of the mobile terminal, and when the location of the mobile terminal is outdoors or belongs to a place set by the user, step S201 is executed.

[0066] Specifically, the location of the mobile terminal may be acquired through a GPS positioning method or a base station positioning method. Because when the mobile terminal user is outdoors, it is likely to be in a road or a public place, the user can set a public meeting place with a loudspeaker, a railway crossing, a crossing where traffic accidents occur frequently, etc. as the place set by the user. Applying the tec...

[0067] In the third embodiment of the present invention, a device for processing ambient sound during a call is located on a mobile terminal. The device is as follows: image 3 shown, including the following components:

[0068] 1) The collection module 100 is used to collect environmental sound signals when the user is talking through an earphone inserted into the mobile terminal;

[0069] Specifically, the acquisition module 100 is implemented in the following three situations:

[0070] When the earphone is a single-listening earphone, the acquisition module 100 uses the microphone on the mobile terminal to collect the ambient sound signal;

[0071] When the earphone is an earphone with a microphone, the acquisition module 100 uses the microphone on the mobile terminal to collect the ambient sound signal, or uses the microphone of the earphone to collect the ambient sound signal;

[0072] In the case that the mobile terminal has both the main microphone and the auxiliary m...

Abstract

The present invention proposes a method and device for processing ambient sound during a call. The method includes: collecting an ambient sound signal when the user is talking through an earphone inserted into a mobile terminal; When the key sound signal is received, the voice volume of the other party is reduced, and the key sound signal is superimposed and played through the earphone. The device includes: a collection module and a processing module. The invention can effectively prevent accidents caused by missing key voice information in the surrounding environment when the earphone is used for answering and calling.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for processing ambient sound during a call. Background technique [0002] When the mobile terminal is plugged with an earphone for the user to make and receive calls, the sound heard by the human ear is the sound on the earphone channel. I don’t understand some key voice information of the surrounding environment, and it is easy to appear when listening to music or making a phone call with headphones outdoors: 1) A traffic accident occurs at a traffic intersection; 2) When people around ask for help or call my name, etc., I don’t hear it. 3) Missing the emergency warning information played by the broadcast, etc. [0003] How to effectively prevent the occurrence of the above-mentioned situation when using earphones to answer and make calls is a problem to be solved urgently in this field. Contents of the invention [0004] The technical problem to b...
