Embodiment 1

[0075] figure 1 It is a flow chart of the sound effect control method according to Embodiment 1 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, detect 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, a tablet computer, a notebook, etc., to make a hands-free call such as a voice hands-free call or a video hands-free call, the mobile terminal can detect whether the hands-free call channel is blocked. For example, when a user uses a mobile phone to make a hands-free call, the mobile phone can detect whether its own microphone and / or its own speaker are blocked, for example, the microphone of the mobile phone is blocked by the user or the platform, and the speaker of the mobile phone is blocked by the user or the platform Wait.

[0078] Step S120, when i...

Embodiment 2

[0086] Figure 2a It is a flow chart of the 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. Such as Figure 2a as shown, Figure 2a The shown method is mainly a method of 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, when F is detected 1 -F 2 ≥F 3 , it is determined that the microphone is blocked, where F 1 Indicates the sound pressure of the microphone in the first period, F 2 Indicates 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 are many ways to detect the change of the sound pressure of the microphone of the mobile terminal...

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. Such as 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 exampl...

Abstract

The present invention relates to a sound effect control method and apparatus, where the sound effect control method includes: when a hands-free call is performed for a mobile terminal, detecting whether a hands-free call channel of the mobile terminal is shielded; and adjusting a configuration of the hands-free call channel of the mobile terminal and / or outputting an alarm signal to inform a user that the hands-free call channel is shielded, when it is detected that the hands-free call channel of the mobile terminal is shielded. According to the sound effect control method in embodiments of the present invention, when a hands-free call is performed for a mobile terminal, whether a hands-free call channel of the mobile terminal is shielded is detected; when the hands-free call channel of the mobile terminal is shielded, a configuration of the hands-free call channel of the mobile terminal is adjusted and / or an alarm signal is output, which can effectively improve quality of the hands-free call of the mobile terminal.

Description

technical field [0001] The 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 handsfree to make a call. The existing echo suppression scheme can improve the effect of hands-free calling and solve the voice problem when using a mobile phone for hands-free calling. [0003] However, when the mobile phone is making a hands-free call, the microphone (Mic) or speaker (Speaker) of the mobile phone may be blocked. For example, the microphone or speaker of the mobile phone may be blocked by the user's hand, or by other objects, or the microphone located on the back of the mobile phone may be blocked when the mobile phone is placed on a table. [0004] Existing hands-free audio solutions are mainly aimed at echo suppression in the scenario where the user normally holds the mobile phone, and cannot be applied to the above-...
