A microphone integrated with an infrared sensing function

Abstract

The invention relates to the technical field of electronic equipment,in particular to a microphone integrating an infrared sensing function. The method is characterized in that the microphone comprises a microphone body, the microphone body is provided with an acoustic through hole, an infrared transmitting device and an infrared receiving device are arranged at the positions, corresponding to theacoustic through holes, in the microphone body; the infrared transmitting device and the infrared receiving device are respectively connected with a circuit processing unit, the transmitting direction of the infrared transmitting device faces the acoustic through hole, and the receiving direction of the infrared receiving device faces the acoustic through hole. According to the invention, by designing the microphone integrated with the infrared sensing function, the distance of an object can be calculated through the delay of near-infrared receiving judgment time, and pressing misjudgment ofa non-human body can also be avoided through the pressure sensor.The device is simple in structure, easy to operate and suitable for various devices.

Description

technical field [0001] The invention relates to the technical field of electronic equipment, in particular to a microphone integrated with an infrared sensing function. Background technique [0002] In the existing micro-devices such as true wireless stereo bluetooth earphones and hearing aids, switches are required. There are generally two options for setting switches for micro-devices. One is the traditional mechanical switch. The advantage of the mechanical switch is that it is not easy to misjudge. It is easy to be damaged, but its large size cannot meet the requirements to achieve precise control; another option is capacitive type, the surface is touch type, which must be touched by the human body, such as a finger, which is costly, and it is easy to accidentally touch it when it comes into contact with the human body. Contents of the invention [0003] The object of the present invention is to provide a microphone with integrated infrared sensing function to solve th...

[0002] In the existing micro-devices such as true wireless stereo bluetooth earphones and hearing aids, switches are required. There are generally two options for setting switches for micro-devices. One is the traditional mechanical switch. The advantage of the mechanical switch is that it is not easy to misjudge. It is easy to damage, but the volume is too large to meet the requirements to achieve precise control; another option is capacitive, the surface is touch-type, and the human body must be touched by the human body, such as a finger, which is costly, and it is easy to accidentally touch with the human body
