Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art without creative labor it is obtained it is all its
His embodiment, shall fall within the protection scope of the present invention.
It should be noted that in the absence of conflict, the feature in embodiment and embodiment in the present invention can phase
Mutually combination.
The present invention will be further explained below with reference to the attached drawings and specific examples, but not as the limitation of the invention.
Because itself has microphone on micromodule equipment, it is therefore contemplated that whether can multi-use, in recent years using micro electronmechanical
The integrated MEMS microphone of system process start by batch application to mobile phone, laptop, wireless Bluetooth headsets,
In the electronic products such as hearing aid, encapsulation volume is smaller than traditional electret microphone, therefore is produced by most of microphone
The favor of quotient.
As shown in Figure 1, a kind of microphone of integrated infrared sensing function, comprising:
One microphone body 1, is arranged acoustics through-hole 2 in microphone body 1, opposite with acoustics through-hole 2 in microphone body 1
An infrared launcher 3 and an infrared receiving device 4 is arranged in the position answered, and infrared launcher 3 and infrared receiving device 4 are distinguished
It is connect with a processing of circuit unit 5, towards acoustics through-hole 2, infrared receiving device 4 connects the direction of the launch of infrared launcher 3
Debit is to towards acoustics through-hole 2.
In preferred embodiments of the present invention, microphone body includes: an Acoustic sensor 6 and specific integrated circuit processing
Unit 7, specific integrated circuit processing unit 7 are connect with Acoustic sensor 6, and user can press acoustics through-hole 2 by finger
It is operated, when finger presses acoustics through-hole 2, Acoustic sensor 6 is just equivalent to a pressure sensor, work as finger
When pressing acoustics through-hole 2 arrives certain pressure value, microphone switch is opened.It thus can be avoided non-human by holding up
Sentence.
In preferred embodiments of the present invention, processing of circuit unit 5 is according to transmitting infrared moment of infrared launcher 3 and red
Infrared receiving device 4 receives the infrared moment and determines time delay, and obtain exterior object close to distance.Near infrared emission device 3
By acoustic aperture 2 to external emission infrared ray, after infrared ray touches object, infrared ray is turned back to be received by near infrared ray back and be filled
4 receptions are set, show that the distance between object and microphone body 1 are more from the received time is emitted to by calculating near infrared ray
It is few to open microphone switch.
In preferred embodiments of the present invention, the acoustics through-hole 2 of microphone body 1 is provided with an Air Filter, passes through Air Filter
1 built-in space of microphone can be fallen into avoid biggish dust and particle sundries, the function of microphone 1 is impacted.
