Problems solved by technology

Different models of mobile phones have different judgments on this state. For example, Apple’s iphone6 ​​interprets this state as a headset without a microphone, thereby enabling the built-in microphone of the mobile phone, and the mute is invalid, resulting in poor applicability and stability of the headset.

Embodiment Construction

[0032] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0033] Such as figure 2 Shown, be the mute circuit of the microphone on a kind of earphone of the present invention, comprise:

[0034] Toggle switch, the microphone and ground resistance R1 set on the earphone; the toggle switch is a single-pole double-throw 1P2T toggle switch;

[0035] Wherein, the first end of the 1P2T toggle switch is grounded through the ground resistance R1;

[0036] The second end of the 1P2T toggle switch is connected to the audio signal MIC signal of the earphone audio jack Audio Jack;

[0037] The third end of the 1P2T toggle switch is connected to the first end of the microphone;

[0038] The second end of the microphone is grounded.

[0039] The second end of the 1P2T toggle switch is the common end of...

Abstract

The invention discloses a mute circuit and method for a microphone on an earphone. The mute circuit includes: a toggle switch, a microphone provided on the earphone and a ground resistance; wherein, the first end of the toggle switch is grounded through the ground resistance; the second end of the toggle switch is connected to the earphone The audio signal MIC signal of the audio jack Audio Jack is connected; the third end of the toggle switch is connected to the first end of the microphone; the second end of the microphone is grounded; the second end of the toggle switch is a dial The common end of the toggle switch is such that when the first end and the second end of the toggle switch are connected, the audio signal MIC signal of the audio jack of the earphone is grounded with the resistance to ground. The invention can stably realize the mute function of the microphone.

Description

technical field [0001] The invention relates to a mute technology of a terminal earphone, in particular to a mute circuit and method for a microphone on the earphone. Background technique [0002] Currently, headsets that work with phones have a microphone-mute feature. The usual microphone mute circuit is to insert a toggle switch in series in the microphone signal line, and disconnecting the signal means that the microphone is muted. [0003] figure 1 It is a microphone mute circuit in the prior art. When the 2-3 pins of the toggle switch are turned on, the microphone works normally; Cause different models of mobile phones to misread this state. [0004] That is to say, when the toggle switch is turned off in this circuit, the microphone signal line on the mobile phone side is suspended. Different models of mobile phones judge this state differently. For example, Apple's iphone6 ​​interprets this state as a headset without a microphone, thereby enabling the built-in mi...
