[0001] The present invention relates to the technical field of Bluetooth headsets, and in particular to a method for realizing a hearing aid function based on a Bluetooth headset chip and a Bluetooth headset. Background Art

[0002] A Bluetooth headset is a type of headset that connects wirelessly to a device via Bluetooth technology. It allows users to enjoy audio playback or make voice calls without a physical connection. The main advantages of Bluetooth headsets are convenience and flexibility.

[0003] Currently, the chips of Bluetooth headsets on the market are mainly composed of Bluetooth wireless communication modules, audio processing modules, power management modules, interface modules and noise cancellation modules. Although they can allow users to make voice calls and listen to music wirelessly through wireless audio transmission, this is only for users without hearing impairments. When encountering hearing-impaired users who cannot hear high-frequency sounds due to cochlear damage or hearing-impaired users who cannot hear low-frequency sounds due to ear canal or middle ear damage, the users will not be able to hear the sounds played by the device, which will affect the scope of application of the device.

[0004] To this end, the present invention provides a method for realizing a hearing aid function based on a Bluetooth headset chip and a Bluetooth headset, which solves the above-mentioned problem by adding a hearing aid function. Summary of the Invention

[0005] In view of the deficiencies in the prior art, the present invention provides a method for realizing a hearing aid function based on a Bluetooth headset chip and a Bluetooth headset, which solves the above problems.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a Bluetooth headset, including a protective plate, the top and bottom of the protective plate are fixedly connected with connecting wires, the end of the connecting wire away from the protective plate is fixedly connected to the headset body, the center of the inner cavity of the protective plate is fixedly connected to a function board, one side of the function board is fixedly connected to a main control module and a Bluetooth module, and the other side of the function board is fixedly connected to an earphone transmission module, a signal control module, an earphone control module and a power supply module.

[0007] Preferably, there are two earphone bodies, and both earphone bodies include an earphone shell, and a microphone and a speaker are fixedly connected to the interior of the earphone shell.

[0008] Preferably, the main control module includes a selection and control unit, an analysis and transmission unit, a hearing aid unit, a call unit, a volume control unit and an audio control unit. The selection and control unit is connected to the analysis and transmission unit for signal transmission, and the analysis and transmission unit is respectively connected to the hearing aid unit, the call unit, the volume control unit and the audio control unit for signal transmission.

[0009] Preferably, the Bluetooth module includes a radio frequency unit, a Bluetooth protocol stack and a Bluetooth storage unit, and the Bluetooth protocol stack is respectively connected to the radio frequency unit and the Bluetooth protocol stack for signal intercommunication.

[0010] Preferably, the headset transmission module includes a microphone input unit and a speaker output unit, the microphone input unit is connected to the microphone for signal reception, and the speaker output unit is connected to the audio for signal transmission.

[0011] Preferably, the signal control module includes a distance measuring unit, a signal encoding unit, a noise filtering unit, a signal storage unit, a comparison and analysis unit, a signal extraction unit, an analysis and transmission unit and a speech generation unit. The signal encoding unit is connected to the distance measuring unit and the radio frequency unit for signal reception, the signal encoding unit is connected to the noise filtering unit for signal transmission, the noise filtering unit is connected to the signal extraction unit for signal transmission, the comparison and analysis unit is connected to the signal storage unit and the signal extraction unit for signal reception, the comparison and analysis unit is connected to the analysis and transmission unit and the speech generation unit for signal transmission, the speech generation unit is connected to the analysis and transmission unit for signal transmission, and the analysis and transmission unit is connected to the speaker output unit and the radio frequency unit for signal transmission.

[0012] Preferably, the distance measuring unit includes a time difference ranging element and a sound pressure level ranging element, and both the time difference ranging element and the sound pressure level ranging element are connected to the microphone input unit and the radio frequency unit for signal reception.

[0013] The method for implementing the hearing aid function of the above-mentioned Bluetooth headset based on the Bluetooth headset chip includes the following steps:

[0014] Step 1: The user needs to input the audio volume and volume control instructions to the selection control unit, so that the volume control unit and the audio control unit allow the headset control module to control the audio volume and volume of the sound played by the speaker;

[0015] Step 2: The user needs to input a hearing aid instruction to the selection control unit so that the hearing aid unit turns on the subsequent module units;

[0016] Step 3: After the hearing aid unit turns on the subsequent module units, the microphone input unit collects the sound signals received by the two microphones and then transmits them to the time difference ranging element and the sound pressure level ranging element;

[0017] Step 4: The time difference ranging component, which receives the two sound signals, determines the distance between each sound and the user by calculating the time difference between the sounds reaching the two microphones. The sound pressure level ranging component, which receives the two sound signals, determines the distance between each sound and the user by calculating the intensity of the sound source in the two sound signals.

[0019] Step six: The signal extraction unit analyzes and extracts the received signal, and then transmits the sound signal and the two distance signals to the comparison and analysis unit. The comparison and analysis unit then compares the sound signal with the warning sound signal stored in the signal storage unit by receiving the signals from the signal storage unit and the signal extraction unit, and then compares the two distance signals. The signal is then transmitted to the analysis and transmission unit. Finally, the analysis and transmission unit transmits the signal to the speaker output unit, and then the speaker output unit transmits the signal to the audio, so that the audio amplifies the sound to the user, thereby achieving a hearing aid effect. When the distance of the warning signal is closer, the comparison and analysis unit also needs to transmit a prompt signal to the voice generation unit, and then the voice generation unit generates a prompt voice signal, and then the voice generation unit transmits the prompt voice signal to the analysis and transmission unit, and then the analysis and transmission unit transmits the signal to the speaker output unit, so that the audio also provides voice prompts to the user.

[0040] In this embodiment, the Bluetooth call operation of the Bluetooth headset includes the following steps:

[0041] Step 1: The user needs to input a normal working instruction to the selection control unit 14 so that the communication unit 17 turns on the subsequent module units;

[0042] Step 2: The radio frequency unit 20 associates with the external Bluetooth signal by transmitting a wireless signal, and then connects with the associated signal through the Bluetooth protocol stack 21. The Bluetooth storage unit 22 can store the associated signal, and then in subsequent associations, the Bluetooth protocol stack 21 can directly associate it.

[0043] Step 3: After the Bluetooth association is completed, the radio frequency unit 20 can receive the voice information sent by the external Bluetooth signal and then transmit it to the signal encoding unit 26;

[0044] Step 4: The signal encoding unit 26 converts the voice signal into a sound signal that can be subsequently played by the speaker 13 through encoding and decoding. The sound signal is then transmitted to the noise filtering unit 27. The noise filtering unit 27 further filters the sound signal to improve its quality. Finally, the filtered sound signal is transmitted to the signal extraction unit 30.

[0045] Step 5: The signal extraction unit 30 directly transmits the sound signal to the comparison and analysis unit 29, which then analyzes the sound signal.

[0046] Step 6: The microphone input unit 23 receives what the user says and transmits it to the distance measurement unit 25. After analysis by the distance measurement unit 25, the sound signal is transmitted to the signal encoding unit 26, the noise filtering unit 27, the signal extraction unit 30 and the comparison and analysis unit 29 in sequence. Because the sound signal has a distance signal, the comparison and analysis unit 29 will allow the analysis and transmission unit 31 to transmit the signal to the radio frequency unit 20 after transmitting it to the analysis and transmission unit 31, and then allow the radio frequency unit 20 to transmit the signal to the external Bluetooth device.

[0047] Example 3:

[0048] This embodiment provides a technical solution based on the first and second embodiments: a method for implementing the hearing aid function of a Bluetooth headset based on a Bluetooth headset chip. The method for implementing the hearing aid function based on a Bluetooth headset chip includes the following steps:

[0049] Step 1: The user needs to input audio volume and volume control instructions to the selection control unit 14, so that the volume control unit 18 and the audio control unit 19 allow the headset control module 9 to control the audio volume and volume of the sound played by the speaker 13;

[0050] Step 2: The user needs to input a hearing aid instruction to the selection and control unit 14, so that the hearing aid unit 16 turns on the subsequent module units;

[0051] Step 3: After the hearing aid unit 16 turns on the subsequent module units, the microphone input unit 23 collects the sound signals received by the two microphones 12 and then transmits them to the time difference ranging element 33 and the sound pressure level ranging element 34;

[0052] Step 4: The time difference ranging element 33 receives the two sound signals and determines the distance between each sound and the user by calculating the time difference between the sounds reaching the two microphones 12. The sound pressure level ranging element 34 receives the two sound signals and determines the distance between each sound and the user by calculating the intensity of the sound source in the two sound signals. Finally, the two distance signals and the two sound signals are transmitted to the signal encoding unit 26.

[0053] Step 5: The signal encoding unit 26 converts the two sound signals into sound signals that can be subsequently played by the speaker 13 through encoding and decoding. The sound signals are then transmitted to the noise filtering unit 27. The noise filtering unit 27 further filters the sound signals to improve their quality. Finally, the filtered sound signals and the two distance signals are transmitted to the signal extraction unit 30.

[0054] Step 6: The signal extraction unit 30 analyzes and extracts the received signal, and then transmits the sound signal and the two distance signals to the comparison and analysis unit 29. The comparison and analysis unit 29 then compares the sound signal with the warning sound signal stored in the signal storage unit 28 by receiving the signals from the signal storage unit 28 and the signal extraction unit 30. The two distance signals are then compared and the signal is then transmitted to the analysis and transmission unit 31. Finally, the analysis and transmission unit 31 transmits the signal to the speaker output unit 24, which then transmits the signal to the audio 13, so that the audio 13 amplifies the sound to the user, thereby achieving a hearing aid effect. When the distance of the warning signal is close, the comparison and analysis unit 29 also needs to transmit a prompt signal to the voice generation unit 32, and then the voice generation unit 32 generates a prompt voice signal, and then the voice generation unit 32 transmits the prompt voice signal to the analysis and transmission unit 31, which then transmits the signal to the speaker output unit 24, so that the audio 13 also provides a voice prompt to the user.
