Description

Technical Field

[0001] The utility model relates to the technical field of earphones, in particular to a Bluetooth head-mounted protective earphone with noise display. Background Art

[0002] In the field of professional protective headphone technology, the demand for hearing protection is growing, especially in high-noise environments such as shooting ranges, hunting, logging and other places. Existing noise-cancelling headphones mainly achieve noise reduction in two ways: active noise reduction and passive noise reduction. Active noise reduction technology uses microphones to capture ambient noise and circuits to generate opposite sound waves to cancel out the noise, while passive noise reduction relies on the physical structure of the headphones and sound insulation materials to block noise.

[0003] Daily high noise levels not only damage hearing, but also have an impact on overall physical health. In response to the need for hearing protection, noise-canceling protective headphones have appeared on the market, but none of these noise-canceling protective headphones can let users know the specific sound pressure value of the ambient noise at the time, which limits users' awareness of ambient noise and the timely adoption of hearing protection measures; in addition, most noise-canceling headphones on the market focus on noise reduction performance, but are relatively simple in terms of user interaction and additional functions, lacking innovations that attract young users.

[0053] Working principle of the utility model

[0054] Function of display screen 65: long press the "sound pickup switch button 73" to turn on the noise display function, and the noise signals collected by the left microphone 100 and the right microphone 200 in the left ear shell 6 and the right ear shell 7 are sent to the digital signal processor 300 on the PCB main board 76. After being processed by the digital signal processor 300, they are converted into display signals and transmitted to the display screen 65 through the branch cable 654 in the connecting cable 10, the connector 653 and the display screen FPC651. The display screen 65 displays the specific value of the ambient noise. Long press the "sound pickup switch button 73" again to turn off the noise display function.

[0055] Sound pickup function: short press the "sound pickup switch button 73" to turn on the sound pickup function (i.e., the ambient sound noise reduction function). The digital signal processor 300 on the PCB main board 76 can suppress the noise collected by the left microphone 100 and the right microphone 200 and enhance the gain of the effective sound (sound pickup enhancement ≥ 12dB). Short press the "sound pickup switch button 73" again to turn off the sound pickup function. The sound signal processed by the digital signal processor on the PCB main board is transmitted to the left speaker assembly 67 and the right speaker assembly 78 for playback. At the same time, the volume knob 71 can adjust the volume of the playback sound.

[0056] When the battery 66 supplies power to the PCB mainboard 76 normally, press and hold the "pickup switch button 73" for 2 seconds to turn on the device and start the ambient noise display function. The left microphone 100 and the right microphone 200 collect ambient noise and transmit it to the Bluetooth / digital signal processor 300 on the mainboard. The Bluetooth / digital signal processor 300 converts analog-to-digital noise into digital signal processing to form a specific digital sound pressure level and transmits it to the display screen 65. The display screen 65 displays the specific values ​​of different ambient noises and displays the health of the environment in different colors. At the same time, the sound pickup function keeps the sound pressure of the ambient sound pickup headset replayed at around 85dB. When the "Bluetooth button 74" is short pressed, the sound pickup switches to the Bluetooth playback state, and the light indicator 75 flashes for pairing. If the pairing is successful, the light indicator 75 stays on and Bluetooth can be played.

[0057] Bluetooth function: Short press "Bluetooth button 74" to turn on the Bluetooth function of the headset, connect it to external devices such as mobile phones and PADs to listen to music, and the "indicator light 75" will be on when the Bluetooth connection is successful, indicating the connection status. Short press "Bluetooth button 74" again to turn off the Bluetooth function of the headset, and the indicator light 75 will go out. Long press "Bluetooth button 74" to enter the pairing state, and the "indicator light 75" will flash continuously. After the Bluetooth and device are successfully connected, the "indicator light 75" will become on.
