The described embodiments are part of the embodiments of the application, rather than all the embodiments of the application.

[0029] Therefore, the following detailed description of the embodiments of the application provided in the drawings is not intended to limit the scope of the claimed application, but only represents selected embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the application.

[0030] Embodiment 1:

[0031] Please refer to the drawings Figure 1 The headset with air pressure reminding function of the application comprises a pressure monitoring module 1, a receiving module 2 and a playing module 3.

[0032] The pressure monitoring module 1 is used for monitoring the air pressure in the ear when the headset is carried.

[0033] The receiving module 2 is electrically connected with the pressure detection module, and the receiving module 2 is used for receiving the air pressure monitored by the pressure monitoring module 1 and converting it into an electrical signal.

[0034] The playing module 3 is electrically connected with the receiving module 2, and the playing module 3 is used for playing the air pressure reminding words, and the receiving module 2 controls the starting of the air pressure reminding words of the playing module 3.

[0035] In the headset in the embodiment, the air pressure threshold is set, when the pressure monitoring module 1 monitors that the air pressure in the ear exceeds the threshold, the receiving module 2 receives the pressure signal and decodes it into an electrical signal, controls the starting of the playing module 3, and then the prompt sound occurs immediately, prompting the user to take off the headset for rest. Through the setting, early warning is realized, the pressure on the ear caused by the air pressure is avoided, the wearing comfort of the headset is effectively improved, and then the health of the ear of the user is ensured. And the competitiveness of the product can be improved, and the product is more popular in the market.

[0036] Embodiment 2:

[0037] The difference between the embodiment and the embodiment 1 is that, referring to Figure 2 The pressure monitoring module of the embodiment includes the pressure sensor U4, and the receiving module 2 includes the wireless transmitting chip U1, and the pressure sensor U4 is connected with the wireless transmitting chip U1.

[0038] It can be understood that the pressure sensor U4 converts the pressure value into an electrical signal, which is usually an analog voltage signal or a current signal output. Common output forms include 0-5V voltage output or 4-20mA current output, and these signals can be directly read and processed by the wireless transmitting chip U1. The pressure sensor U4 is responsible for monitoring the air pressure value in the ear when wearing the headset, and when the air pressure value exceeds the threshold, the receiving module 2 controls the starting of the playing module 3, and then the prompt sound is played to remind the wearer to take off the headset for rest.

[0039] The wireless transmitting chip U1 is a 2.4G wireless transmitting chip, supports low-power wireless communication, usually supports protocols such as Bluetooth, Wi-Fi, ZigBee, etc., and can realize short-distance data transmission. The integrated modem is used for efficient signal modulation and demodulation to ensure stable transmission of signals in the wireless channel. The integrated power amplifier, low-noise amplifier, filter, etc. reduce the demand for external components. It is mainly responsible for receiving wireless signals, decompression, and decoding into analog signals to drive the playing module 3 to sound.

[0040] Specifically, the pressure sensor U4 includes a transmission pin SCL1 and a transmission pin SDA1, and the wireless transmitting chip U1 includes an input pin GPIO6 and an input pin GPIO7; the transmission pin SCL1 is connected with the input pin GPIO6, and the transmission pin SDA1 is connected with the input pin GPIO7. Through the setting, the air pressure value in the ear is accurately monitored and transmitted, and then the playing module 3 plays the prompt sound in time, effectively protects the ear, and improves the wearing comfort.

[0041] In some embodiments, the pressure sensor U4 further includes a protection pin WP, a power supply pin VCC, address selection pins (A0 and A1), a spare pin NC, and a ground pin GND; the protection pin WP, the address selection pins (A0 and A1), the spare pin NC, and the ground pin GND are all connected to ground, and the power supply pin VCC is connected to an external power supply. Among them, if the protection pin WP is connected to a high level, the write operation of the device may be disabled to protect the stored data from being modified accidentally. By connecting these pins to high or low levels, the address selection pins (A0 and A1) can select different I2C addresses, so that multiple sensors of the same type can coexist on the same bus. Through this setting, the accurate monitoring of the pressure sensor U4 can be ensured, and the stable operation of the pressure sensor U4 can be ensured.

[0042] In some embodiments, referring to Figure 3 , the pressure monitoring module further includes a debugging unit 11 connected between the pressure sensor U4 and the wireless transmission chip U1. The debugging unit 11 uses IIC Debug, which is a process of debugging and verifying in I2C communication, to ensure normal communication between devices. By using appropriate tools and methods, developers can effectively identify and solve problems in I2C communication, thereby improving the reliability and stability of the system.

[0043] Specifically, the debugging unit 11 includes a serial data end SDA2, a serial clock end SCL2, and a voltage end V+, the serial data end SDA2 is connected between the transmission pin SDA1 and the input pin GPIO7, the serial clock end SCL2 is connected between the transmission pin SCL1 and the input pin GPIO6, and the voltage end V+ is connected to an external power supply. Among them, the serial data end SDA2 is used to transmit data between the master device and the slave device. Data is transmitted in the form of bits on the SDA line, which supports bidirectional communication. The serial clock end SCL2 provides a clock signal, and the master device (usually a microcontroller) generates the SCL signal to synchronize data transmission. Whenever the SCL signal rises, data is read or written on the SDA line, and the master device controls the frequency of SCL, thereby determining the speed of data transmission. The serial data end SDA2 and the serial clock end SCL2 are responsible for data transmission and clock signal generation in I2C communication, respectively.

[0044] Through the above setting, an oscilloscope or logic analyzer can be used to monitor the SCL and SDA signals during debugging to ensure the timing and integrity of data transmission, thereby realizing the function of signal monitoring. If the I2C device cannot communicate normally, the waveforms of the SCL and SDA signals can be checked during debugging to confirm whether there is a clock signal or data transmission problem, thereby realizing the function of troubleshooting.

[0045] Embodiment 3:

[0046] The difference between the embodiment and embodiment 1 is that, referring to Figures 4-5 , the embodiment further comprises a charging module 4 and an external unit 5, the charging module 4 is connected with the receiving module 2, and the charging module 4 and the receiving module 2 are both connected with the external unit 5. The external unit 5 is a USB interface.

[0047] The charging module 4 comprises a charging management unit 41 and a protection unit 42, the protection unit 42 is connected between the charging management unit 41 and the external unit 5, and the charging management unit 41 is connected with the receiving module 2.

[0048] Specifically, the charging management unit 41 comprises a management chip U2, which is used to support the adjustment of charging current and the indication of state. The management chip U2 is a single lithium battery charging management chip, which provides perfect charging protection functions, including overcharge, overdischarge, short circuit protection, and supports the adjustment of charging current, state indication and other functions.

[0049] The protection unit 42 comprises a protection chip U3, which is connected with the management chip U2. The protection chip U3 is an overcurrent, overvoltage and short circuit protection chip designed for power management, which is usually used to protect the circuit from damage caused by overcurrent or overvoltage.
