Description

Technical Field

[0001] This invention relates to the field of audio equipment, and more specifically to a bone conduction headphone that is comfortable to wear. Background Technology

[0002] Bone conduction headphones are an innovative audio device that uses bone conduction technology to transmit sound. Instead of transmitting sound directly through the eardrum (as with traditional headphones), these headphones convert sound into mechanical vibrations that are transmitted directly to the inner ear via the user's skull. While bone conduction headphones are typically advertised as having no pressure sensation, some users may experience slight discomfort or a vibrating sensation due to the headphones being pressed against the bone, especially after prolonged use. This is particularly true because current bone conduction headphones require the vibrator to be in close contact with the skin to ensure sound quality; prolonged wear can lead to excessive localized pressure on the skin, causing discomfort.

[0003] Existing technologies also propose solutions to alleviate this problem. For example, CN219145559U has contact surfaces on the inner sides of the left and right earpieces that conform to the surfaces behind, on top, and in the middle of the ear. These contact surfaces include contact surfaces for the power supply, left ear hook, and left sound outlet, as well as contact surfaces for the control, right ear hook, and right sound outlet. The arc-shaped connector provides a clamping force to the head. Under the action of this clamping force, the contact surfaces are in contact with the back, top, and middle of the left and right ears, respectively, increasing the friction between the earpiece and the scalp. With the clamping force generated by the arc-shaped connector remaining constant, the contact area between the earpiece and the skin is increased, reducing the pressure of the clamping force on the body and improving wearing comfort. However, the above methods alone cannot completely eliminate the discomfort caused by clamping, so there is an urgent need to propose a new solution to this problem. Summary of the Invention

[0004] To address the aforementioned problems, the present invention provides a comfortable bone conduction headphone, characterized by comprising a battery module, a control module, and a sound-generating unit; The battery module connects the control module and the sound unit, thereby enabling the battery module to supply power to the control module and the sound unit; The control module is connected to the sound-generating unit, and the control module controls the operation of the sound-generating unit. The sound-generating unit includes a frequency divider and a loader. The frequency divider is used to divide the audio signal into high-frequency and low-frequency signals. The high-frequency signal is emitted through the high-frequency resonator module, and the low-frequency signal is emitted through the low-frequency resonator module. The sound-generating unit includes at least two high-frequency resonator modules and at least two low-frequency resonator modules; The high-frequency oscillator module and the low-frequency oscillator module are mounted on the loader. The loader adjusts the position of a single high-frequency oscillator module or a single low-frequency oscillator module, thereby adjusting the pressure applied to the skin by the high-frequency oscillator module or the low-frequency oscillator module.

[0005] The loader includes a loading pump, a pressure plate, and a pressure sensor; each high-frequency oscillator module and each low-frequency oscillator module are mounted on an independent pressure plate, and each pressure plate is equipped with a separate pressure sensor; the loading pump applies pressure to the pressure plate containing one high-frequency oscillator module and one low-frequency oscillator module at a time; the pressure value collected by the pressure sensor is used to adjust the pressure power of the pressure motor.

[0006] Each pressure plate is equipped with an airbag, which is connected to a loading pump. A multi-way valve is installed between the loading pump and the airbag, with each of the multi-way valves connected to an airbag. The loading pump pressurizes the airbag, which in turn squeezes the pressure plate, causing the high-frequency or low-frequency oscillator module on the pressure plate to apply pressure to the skin.

[0007] The pressure sensor is an infrared optical pressure sensor, equipped with an infrared transmitter and an infrared receiver. The infrared transmitter is connected to a semiconductor laser source, and the semiconductor laser source and the infrared transmitter are connected by an optical waveguide. The infrared receiver is placed adjacent to the infrared transmitter; after the infrared light emitted by the infrared transmitter reaches the skin, a portion is absorbed by the skin, and a portion of the unabsorbed light returns and is received by the infrared receiver; the pressure applied to the skin by the high-frequency or low-frequency oscillator module is determined based on the intensity of the infrared light collected by the infrared receiver. When the skin is subjected to different pressures, the blood flow intensity in the capillaries within the skin changes, which in turn causes changes in the absorption intensity of infrared light by the skin, further affecting the intensity of the infrared light returning to the infrared receiver. Thus, the pressure applied to the skin by the high-frequency or low-frequency oscillator module is determined based on the intensity of the infrared light collected by the infrared receiver.

[0008] The control module is connected to the loader, and the control module controls the operation of the loader; the loader adjusts the pressure applied to the skin by the high-frequency oscillator module or the low-frequency oscillator module according to the instructions of the control module; The control module adjusts the loader's operating mode, which has three modes: Mode 1: Time Adjustment Mode; The loader acquires the return data from all pressure sensors in real time, namely the infrared light intensity collected by the infrared receiver, and sends it to the control module. When the detection value of the infrared receiver with the highest infrared light intensity is higher than the first threshold, the calculation of time t1 begins. When t1 is greater than or equal to T1, the control module sends an adjustment command. After receiving the adjustment command, the loader changes the pressure applied to the skin by the high-frequency or low-frequency oscillator module. The pressure applied by the high-frequency and low-frequency oscillator modules with the highest current pressure is reduced, and the pressure applied by the high-frequency and low-frequency oscillator modules with the lowest current pressure is increased and made to become the high-frequency and low-frequency oscillator modules with the highest pressure. Mode 2, Pressure Threshold Mode; The loader acquires the return data from the pressure sensor in real time, namely the infrared light intensity collected by the infrared receiver, and sends it to the control module. When the detection value of the infrared receiver with the highest infrared light intensity is higher than the second threshold, the control module sends an adjustment command. After receiving the adjustment command, the loader changes the pressure applied to the skin by the high-frequency or low-frequency oscillator module. It reduces the pressure applied by the high-frequency and low-frequency oscillator modules with the highest current pressure, and increases the pressure applied by the high-frequency and low-frequency oscillator modules with the lowest current pressure, making them the high-frequency and low-frequency oscillator modules with the highest pressure. Mode 3, Hybrid Mode; The loader acquires the return data from the pressure sensor in real time, namely the infrared light intensity collected by the infrared receiver, and sends it to the control module. When the detection value of the infrared receiver with the highest infrared light intensity is higher than the first threshold, the time t1 is calculated. When t1 is greater than or equal to T1, the control module sends an adjustment command. Alternatively, when the detection value of the infrared receiver with the highest infrared light intensity is higher than the second threshold, the control module sends an adjustment command. After receiving the adjustment command, the loader changes the pressure applied to the skin by the high-frequency or low-frequency oscillator module; it reduces the pressure applied by the high-frequency and low-frequency oscillator modules with the highest current pressure, and increases the pressure applied by the high-frequency and low-frequency oscillator modules with the lowest current pressure, making them the high-frequency and low-frequency oscillator modules with the highest pressure. The first and second thresholds are preset thresholds. Time t1 is calculated when the infrared receiver with the highest infrared light intensity exceeds the first threshold. When t1 is greater than or equal to T1, the user feels pressure on the headphone wearing position. Similarly, when the infrared receiver with the highest infrared light intensity exceeds the second threshold, the user feels pressure on the headphone wearing position. T1 is the threshold time, which can be set as needed.

[0009] A method for using a comfortable bone conduction headphone, comprising the following steps: Step A The adjustment parameters are obtained through the input button on the bone conduction headphones, and the first threshold, the second threshold, and the working mode of the loader are obtained based on the adjustment parameters. The first threshold and the second threshold are set thresholds; time t1 is calculated when the detection value of the infrared receiver with the highest infrared light intensity is higher than the first threshold; when t1 is greater than or equal to T1, the user feels pressure on the position of wearing the headphones; when the detection value of the infrared receiver with the highest infrared light intensity is higher than the second threshold, the user feels pressure on the position of wearing the headphones. Step B: The decoder obtains audio data from the audio file, decodes the audio data to obtain an audio signal, and sends the decoded audio signal to the audio amplifier. The audio amplifier amplifies the audio signal and then sends it to the crossover. The frequency divider splits the audio signal into a high-frequency signal and a low-frequency signal; the high-frequency signal is sent to the high-frequency resonator module to produce sound, and the low-frequency signal is sent to the low-frequency resonator module to produce sound. Step C The control module controls the loader to acquire the detection data of the pressure sensor; the infrared light emitted by the infrared emitter is partially absorbed by the skin after reaching it, and the returned light is received by the infrared receiver; the pressure applied to the skin by the high-frequency oscillator module or the low-frequency oscillator module is obtained according to the intensity of the infrared light collected by the infrared receiver. Step D The loader acquires the return data from the pressure sensor in real time and sends it to the control module; the control module sends adjustment commands according to different operating modes. After receiving the adjustment command, the loader changes the positions of the high-frequency oscillator module and the low-frequency oscillator module that are currently under the greatest applied pressure.

[0010] In step D, the control module adjusts the loader's operating mode in three ways: Mode 1: Time Adjustment Mode; The loader acquires the return data from all pressure sensors in real time, namely the infrared light intensity collected by the infrared receiver, and sends it to the control module. When the detection value of the infrared receiver with the highest infrared light intensity is higher than the first threshold, the calculation of time t1 begins. When t1 is greater than or equal to T1, the control module sends an adjustment command. After receiving the adjustment command, the loader changes the pressure applied to the skin by the high-frequency or low-frequency oscillator module. The pressure applied by the high-frequency and low-frequency oscillator modules with the highest current pressure is reduced, and the pressure applied by the high-frequency and low-frequency oscillator modules with the lowest current pressure is increased and made to become the high-frequency and low-frequency oscillator modules with the highest pressure. Mode 2, Pressure Threshold Mode; The loader acquires the return data from the pressure sensor in real time, namely the infrared light intensity collected by the infrared receiver, and sends it to the control module. When the detection value of the infrared receiver with the highest infrared light intensity is higher than the second threshold, the control module sends an adjustment command. After receiving the adjustment command, the loader changes the pressure applied to the skin by the high-frequency or low-frequency oscillator module. It reduces the pressure applied by the high-frequency and low-frequency oscillator modules with the highest current pressure, and increases the pressure applied by the high-frequency and low-frequency oscillator modules with the lowest current pressure, making them the high-frequency and low-frequency oscillator modules with the highest pressure. Mode 3, Hybrid Mode; The loader acquires the return data from the pressure sensor in real time, namely the infrared light intensity collected by the infrared receiver, and sends it to the control module. When the detection value of the infrared receiver with the highest infrared light intensity is higher than the first threshold, the time t1 is calculated. When t1 is greater than or equal to T1, the control module sends an adjustment command. Alternatively, when the detection value of the infrared receiver with the highest infrared light intensity is higher than the second threshold, the control module sends an adjustment command. After receiving the adjustment command, the loader changes the pressure applied to the skin by the high-frequency or low-frequency oscillator module; it reduces the pressure applied by the high-frequency and low-frequency oscillator modules with the highest current pressure, and increases the pressure applied by the high-frequency and low-frequency oscillator modules with the lowest current pressure, making them the high-frequency and low-frequency oscillator modules with the highest pressure. The first and second thresholds are preset thresholds. Time t1 is calculated when the infrared receiver with the highest infrared light intensity exceeds the first threshold. When t1 is greater than or equal to T1, the user feels pressure on the headphone wearing position. Similarly, when the infrared receiver with the highest infrared light intensity exceeds the second threshold, the user feels pressure on the headphone wearing position. T1 is the threshold time, which can be set as needed.

[0011] Among them, multiple levels are pre-set for the first and second thresholds, namely sensitive, normal, and strong; At the sensitive level, the corresponding first and second thresholds are the smallest, and the corresponding high-frequency and low-frequency oscillator modules exert the least pressure on the skin; suitable for sensitive users, the user will change the position of the high-frequency and low-frequency oscillator modules that exert the most pressure when subjected to less pressure, and the high frequency of replacement makes it the least likely for the user to feel discomfort; At the normal level, the corresponding first and second thresholds are moderate, and the pressure applied to the skin by the corresponding high-frequency oscillator module and low-frequency oscillator module is moderate; suitable for ordinary users. Under moderate pressure, the user will change the position of the high-frequency oscillator module and low-frequency oscillator module with the greatest pressure, and the frequency of replacement is moderate, so the user feels moderate. At the highest intensity level, the corresponding first and second thresholds are at their maximum, and the corresponding high-frequency and low-frequency resonator modules exert the greatest pressure on the skin. This is suitable for insensitive users, as the user will only change the position of the high-frequency and low-frequency resonator modules that exert the greatest pressure when subjected to significant pressure. The frequency of replacement is low, minimizing the impact on the user's hearing.

[0012] The beneficial effects of this invention are as follows: The bone conduction headphones of this invention are designed for comfort. The sound unit uses a crossover to divide the audio signal into high and low frequencies, which are then emitted by high-frequency and low-frequency vibrating modules respectively, thus improving the sound effect. The sound unit contains multiple high-frequency and low-frequency vibrating modules, which are mounted on the loader. The sound quality and comfort are optimized by adjusting the pressure of the vibrators on the skin.

[0013] The loader includes a loading pump, a pressure plate, and pressure sensors; each oscillator module is equipped with an independent pressure plate and sensor. The loading pump regulates pressure via an air bladder and valve system to ensure appropriate pressure is applied to the skin. The pressure sensors utilize infrared technology, measuring the pressure exerted by the oscillator on the skin based on changes in the skin's absorption of infrared light.

[0014] The control module connects to and controls the loader, providing three operating modes: time adjustment mode, pressure threshold mode, and hybrid mode. These modes prevent users from feeling pressure on the headphone position by monitoring and adjusting the oscillator module at maximum and minimum pressure. Threshold and time parameters are settable to suit the comfort needs of different users. In summary, this invention combines advanced technology with user-friendly design, providing superior sound quality and a comfortable wearing experience. Attached Figure Description

[0020] Furthermore, in one embodiment, the pressure sensor is an infrared light pressure sensor, which is provided with an infrared transmitter 31 and an infrared receiver 32. The infrared transmitter 31 is connected to a semiconductor laser source, and the semiconductor laser source and the infrared transmitter 31 are connected by an optical waveguide. The infrared receiver 32 is arranged adjacent to the infrared transmitter 31; after the infrared light emitted by the infrared transmitter 31 reaches the skin, a portion of it is absorbed by the skin, and a portion of the unabsorbed light returns and is received by the infrared receiver 32; the pressure applied to the skin by the high-frequency oscillator module 1 or the low-frequency oscillator module 2 is determined according to the intensity of the infrared light collected by the infrared receiver 32. When the skin is subjected to different pressures, the blood flow intensity in the capillaries within the skin changes, which in turn causes a change in the absorption intensity of infrared light by the skin, further affecting the intensity of the infrared light returned to the infrared receiver 32; thus, the pressure applied to the skin by the high-frequency oscillator module 1 or the low-frequency oscillator module 2 is determined based on the intensity of the infrared light collected by the infrared receiver 32.

[0021] The control module is connected to the loader 3, and the control module controls the operation of the loader 3; the loader 3 adjusts the pressure applied to the skin by the high-frequency oscillator module 1 or the low-frequency oscillator module 2 according to the instructions of the control module. Furthermore, in one embodiment, the control module adjusts the operating mode of the loader 3 to have three modes: Mode 1: Time Adjustment Mode; The loader 3 acquires the return data from all pressure sensors in real time, namely the infrared light intensity collected by the infrared receiver 32, and sends it to the control module. When the detection value of the infrared receiver 32 with the highest infrared light intensity is higher than the first threshold, the calculation of time t1 begins. When t1 is greater than or equal to T1, the control module sends an adjustment command. After receiving the adjustment command, the loader 3 changes the pressure applied to the skin by the high-frequency oscillator module 1 or the low-frequency oscillator module 2.

When t1 is greater than or equal to T1, the control module sends an adjustment command. Alternatively, when the detection value of the infrared receiver 32 with the highest infrared light intensity is higher than the second threshold, the control module sends an adjustment command. After receiving the adjustment command, the loader 3 changes the pressure applied to the skin by either the high-frequency oscillator module 1 or the low-frequency oscillator module 2; it reduces the pressure applied by the high-frequency oscillator module 1 and the low-frequency oscillator module 2 that currently apply the highest pressure, and increases the pressure applied by the high-frequency oscillator module 1 and the low-frequency oscillator module 2 that currently apply the lowest pressure, making them the high-frequency oscillator module 1 and the low-frequency oscillator module 2 that apply the highest pressure.
