In order to achieve the purpose, the invention adopts the following technical scheme:
a mask with a Bluetooth microphone comprises a mask body, a battery, a Bluetooth module and a microphone; battery, bluetooth module and microphone all set up in the inside of gauze mask body, and battery, bluetooth module all pass through the line connection with the microphone, and bluetooth module is through communicating through bluetooth is wireless with the cell-phone, and the microphone is used for collecting sound and turns into it the signal, sends the signal for the cell-phone through bluetooth module again.
Preferably, the bluetooth module adopts a bluetooth low energy module 4.2.
In addition, the invention also provides a method for communicating the mask with the Bluetooth microphone with the mobile phone, which adopts the mask with the Bluetooth microphone and specifically comprises the following steps:
step 1: adopting a microphone to carry out analog audio acquisition and digital quantization to obtain quantized digital audio data;
step 2: compressing the digital audio data collected and quantized in the step 1 by an audio compression algorithm;
and step 3: dividing the compressed digital audio data into separated audio messages by the number of packets of the Bluetooth module and transmitting the audio messages to the mobile phone end;
and 4, step 4: the mobile phone receives the separated audio message through Bluetooth communication, and performs audio unpacking and audio decoding;
and 5: and simulating the microphone input of the mobile phone through a microphone input API (application program interface) of the mobile phone.
The invention has the following beneficial technical effects:
1. digital audio transmission
2. The original state of the loudspeaker of the mobile phone is not influenced
After the mobile phone microphone channel is taken over by the Bluetooth microphone, the original normal use of the function of the mobile phone receiver (earphone) channel is not influenced.

Wherein, 1-the mask body; 2-microphone with battery and bluetooth module; 3-filter element.
Detailed Description
The invention is described in further detail below with reference to the following figures and detailed description:
example 1:
as shown in fig. 1, a mask with a bluetooth microphone comprises a mask body, a battery, a bluetooth module and a microphone; battery, bluetooth module and microphone all set up in the inside of gauze mask body, and battery, bluetooth module all pass through the line connection with the microphone, and bluetooth module is through communicating through bluetooth is wireless with the cell-phone, and the microphone is used for collecting sound and turns into it the signal, sends the signal for the cell-phone through bluetooth module again.
The Bluetooth module adopts a low-power Bluetooth module 4.2.
The Bluetooth module is a chip basic circuit set integrating the Bluetooth function and is used for wireless network communication. The bluetooth module is generally composed of a chip, a PCB board and peripheral devices. In brief, the bluetooth module is used to replace wired connection with wireless connection, and forms a personal area network with fixed and mobile information devices, thereby realizing low-cost wireless interconnection communication between the devices.
The Bluetooth modules are divided into 1.2, 2.0, 3.0, 4.0, 4.1, 4.2 and 5.0 according to the standard; the latter is generally compatible with the former product;
the Bluetooth module is divided into a classic Bluetooth module (BT) and a low-power Bluetooth module (BLE) according to application and a support protocol;
classic bluetooth module (BT): the module supporting the bluetooth protocol below 4.0 is generally used for transmission with a relatively large data volume, such as: voice, music, higher data volume transmission, etc.
(BLE): the Module is a Module supporting a bluetooth protocol of 4.0 or higher, also called a BLE Module (bluetooth Low Energy Module), and has the greatest characteristics of reducing cost and power consumption, and is applied to products with higher real-time requirements but lower data rates, such as: remote control (mouse, keyboard), data transmission of sensing devices (heartbeat belt, sphygmomanometer, temperature sensor), and the like.
Example 2:
on the basis of the above embodiment 1, the present invention further provides a method for communication between a mask with a bluetooth microphone and a mobile phone, wherein the flow is shown in fig. 2, and the method specifically includes the following steps:
step 1: adopting a microphone to carry out analog audio acquisition and digital quantization to obtain quantized digital audio data;
