FIG. 1 is a schematic view of the present invention;

reference numerals: the microphone comprises a microphone type handpiece 1, an intelligent touch control body 2, a screwdriver head 3, a hollow microphone shell 4, a microphone 5, a hollow shell 6, a touch screen type switch 7, a sensing area 8 of the hollow microphone shell, a sensing area 9 of the hollow shell and an electronic display screen 10.

Detailed Description

So that the manner in which the above recited features of the present invention can be understood and readily understood, a more particular description of the invention, briefly summarized above, may be had by reference to embodiments, some of which are illustrated in the appended drawings, wherein:

a microphone type electric screwdriver, as shown in fig. 1, which comprises a microphone type handpiece 1, an intelligent touch control body 2 and a screwdriver head 3.

Wherein, microphone aircraft nose 1 includes cavity microphone casing 4, the integration is used for speech recognition based on embedded speech recognition chip and be used for controlling the screwdriver just reversing based on control chip MCU's speech control module and based on microphone 5's audio acquisition module, and the user is when using speech recognition to awaken up the function, and the host computer sends the order that starts speech recognition and awaken up the function and gives speech control module, and speech control module will follow the audio data that microphone 5 gathered convert corresponding identification data into through embedded speech recognition chip, pass back through communication interface and give control chip MCU, and control chip MCU outputs corresponding electric signal control screwdriver just reversing the operation.

Specifically, with the development of technology, the traditional mechanical button operation cannot meet the needs of people, and a more convenient, more natural and more humanized man-machine interaction mode becomes the pursuit of people. The hearing based man-machine interaction approach is undoubtedly one of the most interactive friendly approaches. The embedded voice interaction is a mature electronic technology at present due to simple structure and convenient construction. Compared with the existing intelligent voice recognition system, the embedded voice recognition system has the advantages of small size, low power consumption, high reliability, low cost, flexible installation and the like, although the recognition range, the operation speed and the memory capacity of the embedded voice recognition system are limited to a certain extent, and is particularly suitable for the field of electric screwdrivers. When the screwdriver works specifically, a user triggers a voice recognition awakening function (for example, an audio ' knife ' and a Chinese pronunciation of the knife ' are awakening voice audio frequency) of the electric screwdriver through a specifically set voice recognition audio frequency, the upper computer sends a command for starting the voice recognition awakening function to the voice control module, the voice control module reminds the user of voice selection forward and backward through the power amplifier loudspeaker, the voice control module converts specifically set forward and backward audio data collected from the microphone into corresponding recognition data through the embedded voice recognition chip, the recognition data are returned to the control chip MCU through the communication interface, and the control chip MCU outputs a corresponding electric signal to control the forward and backward rotation of the screwdriver.
