Embodiment 1

[0075] figure 1 It is a flowchart of the sound effect control method according to the first embodiment of the present invention, such as figure 1 As shown, the sound effect control method may include:

[0076] Step S100, when the mobile terminal performs a hands-free call, it is detected whether the hands-free call channel of the mobile terminal is blocked.

[0077] Specifically, when a user uses a mobile terminal, such as a mobile phone, tablet computer, notebook, etc., to conduct a hands-free call, such as a voice hands-free call or a video hands-free call, the mobile terminal can detect whether its hands-free call channel is blocked. For example, when a user uses a mobile phone for a hands-free call, the mobile phone can detect whether its own microphone and / or its own speaker is blocked, for example, the mobile phone's microphone is blocked by the user or the platform, and the mobile phone's speaker is blocked by the user or the platform. Wait.

[0078] Step S120, when ...

Embodiment 2

[0086] Figure 2a It is a flowchart of a sound effect control method according to the second embodiment of the present invention.

[0087] Step S100 in the first embodiment above may include: detecting whether the microphone of the mobile terminal is blocked. like Figure 2a shown, Figure 2a The method shown is mainly a method for detecting whether the microphone of the mobile terminal is blocked, and the method may include:

[0088] Step S200, detecting the change of the sound pressure of the microphone;

[0089] Step S220, after detecting F 1 -F 2 ≥F 3 When , it is determined that the microphone is blocked, where F 1 represents the sound pressure of the microphone in the first period, F 2 represents the sound pressure of the microphone in the second period, the first period is before the second period, F 3 represents the first threshold.

[0090] Specifically, there can be various methods for detecting the change of the sound pressure of the microphone of the mobi...

Embodiment 3

[0103] image 3 It is a flow chart of the sound effect control method according to the third embodiment of the present invention.

[0104] Step S100 in the first embodiment above may include: detecting whether the speaker of the mobile terminal is blocked. like image 3 as shown, image 3 The shown method is mainly a method of detecting whether the speaker of the mobile terminal is blocked, and the method may include:

[0105] Step S300, detecting the change of the acoustic resistance of the speaker;

[0106] Step S320, when R is detected 2 -R 1 ≥R 3 , it is determined that the speaker is blocked, where R 1 Indicates the acoustic resistance of the speaker at the first moment, R 2 Indicates the acoustic resistance of the speaker at the current moment, the first moment is before the current moment, R 3 Indicates the second threshold.

[0107] Specifically, according to the characteristics of the speaker, when the sound outlet of the speaker is blocked by, for example, ...

Abstract

The invention relates to a method and device for controlling the sound effect. The method for controlling the sound effect comprises the step of detecting whether a hands-free call channel of a mobile terminal is sheltered or not when the mobile terminal executes hands-free calls, and the step of adjusting the configuration of the hands-free call channel of the mobile terminal and / or outputting a warning signal to prompt a user that the hands-free call channel is sheltered when the hands-free call channel of the mobile terminal sheltered. According to the method for controlling the sound effect, when the mobile terminal executes the hands-free calls, whether the hands-free call channel of the mobile terminal is sheltered or not is detected, and when the hands-free call channel is sheltered, the configuration of the hands-free call channel of the mobile terminal is adjusted and / or the warning signal is output, and therefore the hands-free call quality of the mobile terminal can be effectively improved.

Description

technical field [0001] The present invention relates to electronic communication technology, in particular to a sound effect control method and device. Background technique [0002] When using a mobile phone to make a call, the user can turn on the hands-free to make a call. The existing echo suppression solution can improve the effect of the hands-free call, and solve the voice problem when the mobile phone is normally used for the hands-free call. [0003] However, when the mobile phone makes a hands-free call, the microphone (Mic) or speaker (Speaker) of the mobile phone may be blocked. For example, the phone's microphone or speaker may be blocked by the user's hand, or by other objects, or when the phone is placed on a table, the microphone located on the back of the phone is blocked. [0004] The existing hands-free sound effect solutions are mainly aimed at echo suppression solutions in the scenario where the user normally holds a mobile phone by hand, and cannot be ...
