[0021] The principle of a hearing aid is to pick up sound signals through a receiving microphone, convert them into electrical signals, amplify them through an audio amplifier, and then restore the electrical signals into sound signals by a broadcasting speaker and transmit them to the human ear, which brings great convenience to hearing-impaired people. Usually, the optimal distance between a hearing aid and a sound-emitting unit is within two meters. When the distance between the hearing aid and the sound-emitting unit exceeds three meters, it is difficult for the receiving microphone in the hearing aid to pick up the sound waves of the sound-emitting unit, resulting in poor broadcasting effect of the broadcasting speaker and affecting the normal use of the hearing aid.

[0022] In order to avoid interference in sound reception and broadcasting of the hearing aid headset and affect its normal use, the present utility model proposes a hearing aid charging case. Referring to Figure 1 , the hearing aid charging case includes;

[0023] A sound collection circuit 10, configured to collect the sound signals of the sound-emitting unit and convert the sound signals into electrical signals;

[0024] A communication circuit 20, the input end of the communication circuit 20 is connected to the output end of the sound collection circuit 10, and the output end of the communication circuit 20 is used to connect to the input end of the hearing aid;

[0025] A main control circuit 30, the control end of the main control circuit 30 is connected to the controlled end of the communication circuit 20; the main control circuit 30 is configured to control the communication circuit 20 to receive the electrical signal, and convert the electrical signal into a wireless signal and then output it to the hearing aid.

[0026] It can be understood that the hearing aid headset in the existing hearing aid is provided with a receiving microphone, an audio amplifier and a broadcasting speaker. During use, the sound signal is picked up by the receiving microphone and converted into an electrical signal, amplified by the audio amplifier, and the electrical signal is restored into a sound signal by the broadcasting speaker and transmitted to the human ear. Usually, the optimal distance between the hearing aid and the sound-emitting unit is within two meters. For example, when the distance between the hearing aid and the TV exceeds three meters, it is difficult for the receiving microphone in the hearing aid to pick up the sound waves of the TV, resulting in poor broadcasting effect of the hearing aid and affecting the normal use of the hearing aid. By arranging the microphone on the hearing aid charging case, the present utility model enables the hearing aid charging case to have the function of picking up sound signals, and at the same time realizes the transmission of sound signals between the hearing aid charging case and the hearing aid through wireless communication technology, so that the hearing aid has a remote hearing aid function, solves the problem of poor broadcasting effect when the existing hearing aid is too far away from the sound-emitting unit, and ensures a good experience for users.

[0027] In this embodiment, the hearing aid device includes a hearing aid and a hearing aid charging box, and the hearing aid charging box includes a sound collection circuit 10, a communication circuit 20 and a main control circuit 30. Optionally, the communication circuit 20 can be implemented by a WIFI device, a Bluetooth device, etc.; the main control circuit 30 can be implemented by an MCU, a DSP (Digital Signal Process), an FPGA (Field Programmable Gate Array), a SOC (System On Chip), etc. This embodiment is described by taking the sound collection circuit 10 as a radio microphone, the signal sending circuit as a Bluetooth device, the main control circuit 30 as an MCU, and the sound unit as a TV as an example. Among them, the Bluetooth device includes a transmitter and a receiver. In actual applications, the hearing aid charging box is placed within two meters of the TV. The radio microphone in the hearing aid charging box collects the sound signal of the TV and converts the sound signal into an electrical signal. The MCU controls the receiver to access the electrical signal of the radio microphone, and controls the transmitter to convert the electrical signal into a wireless signal and transmit it to the hearing aid through wireless communication technology. Reference Figure 3 The hearing aid includes a control circuit, a hearing aid communication circuit, an audio amplifier and a broadcasting speaker. The control circuit controls the hearing aid communication circuit to receive the wireless signal sent by the hearing aid charging box, and converts the wireless signal into an electrical signal and outputs it to the audio amplifier. The audio amplifier amplifies the electrical signal, and the broadcasting speaker restores the electrical signal to an acoustic signal and transmits it to the human ear, thereby realizing the remote hearing aid function. Compared with the prior art, a radio microphone and a communication circuit 20 are arranged in the hearing aid charging box, so that the hearing aid has a remote hearing aid function, optimizes the hearing aid function of the hearing aid, and solves the problem that the existing hearing aid is too far away from the generating unit and has a poor broadcasting effect.

[0028] It should be pointed out that the hearing aid communication circuit in the hearing aid and the communication circuit 20 of the hearing aid charging box are the same communication device, that is, the hearing aid communication circuit is a Bluetooth device, and the hearing aid communication circuit also includes a transmitter and a receiver. Specifically, the control circuit controls the receiver in the hearing aid communication circuit to receive the wireless signal sent by the hearing aid charging box, and controls the transmitter in the hearing aid communication circuit to convert the wireless signal into an electrical signal and output it to the audio amplifier.

[0029] In addition, the hearing aid device has two working modes, namely the short-range working mode and the long-range working mode. When the hearing aid device switches to the long-range working mode, the hearing aid charging case picks up the sound signal of the sound-emitting unit, and sends the processed sound signal to the hearing aid through wireless communication technology. The hearing aid converts the sound signal into an electrical signal and amplifies it, and then transmits it into the human ear to achieve the function of long-range hearing aid. When the hearing aid device switches to the short-range working mode, the hearing aid picks up the sound signal of the sound-emitting unit, converts the sound signal into an electrical signal and amplifies it, and then transmits it into the human ear to achieve the function of short-range hearing aid. It should be noted that in this embodiment, the hearing aid further includes a housing, a button assembly arranged on the surface of the housing, and a hearing aid microphone for picking up the sound-emitting unit. Among them, the hearing aid microphone and the sound collection microphone mentioned above can be the same microphone. Specifically, when the user does not need the long-range hearing aid function, by manually triggering the button assembly, the control circuit in the hearing aid controls the hearing aid device to switch to the short-range working mode according to the trigger signal sent by the button assembly, so as to control the hearing aid microphone to pick up the sound signal of the sound-emitting unit. At the same time, the control circuit sends a control signal to the main control circuit 30 of the hearing aid charging case through the hearing aid communication circuit, so as to trigger the main control circuit 30 to control the sound collection microphone and the communication circuit 20 not to work. That is, in the short-range working mode, the hearing aid charging case does not pick up the sound signal, but the hearing aid picks up the sound signal to pick up the sound signal of the surrounding environment of the hearing aid.

[0030] The utility model provides a hearing aid charging case and a hearing aid device. The hearing aid charging case includes: a sound collection circuit 10, a communication circuit 20, and a main control circuit 30. The input end of the communication circuit 20 is connected to the output end of the sound collection circuit 10, and the output end of the communication circuit 20 is used to connect to the input end of the hearing aid. The control end of the main control circuit 30 is connected to the controlled end of the communication circuit 20. The sound collection circuit 10 is used to collect the sound signal of the sound-emitting unit and convert the sound signal into an electrical signal. The main control circuit 30 is used to control the communication circuit 20 to receive the electrical signal, convert the electrical signal into a wireless signal, and output it to the hearing aid through wireless transmission technology. By arranging the microphone on the hearing aid charging case, the utility model enables the hearing aid charging case to have the function of picking up the sound signal, and realizes the transmission of the sound signal between the hearing aid charging case and the hearing aid through wireless communication technology, so that the hearing aid has the function of long-range hearing aid, and solves the problem of poor broadcasting effect when the hearing aid is too far away from the sound-emitting unit.

[0031] In one embodiment, the communication circuit 20 includes a WIFI device or a Bluetooth device.

[0032] It can be understood that setting the wireless communication device on the hearing aid charging case enables the transmission of sound signals between the hearing aid charging case and the hearing aid through wireless communication technology, endowing the hearing aid with the function of remote hearing assistance. In this embodiment, an example is given with the communication circuit 20 including a Bluetooth device. Among them, the Bluetooth device includes a transmitter and a receiver. Specifically, the main control circuit 30 is used to control the receiver in the Bluetooth device to access the electrical signal of the sound collection microphone, and control the transmitter in the Bluetooth device to convert the electrical signal into a wireless signal and transmit it to the hearing aid through wireless communication technology, thereby realizing the function of remote hearing assistance.

[0033] In one embodiment, the sound collection circuit 10 includes:

[0034] A sound collection microphone, the output end of the sound collection microphone is connected to the input end of the communication circuit 20; the sound collection microphone is used to collect sound signals and convert the sound signals into electrical signals and then output them to the communication circuit 20;

[0035] It can be understood that setting the microphone on the hearing aid charging case enables the hearing aid charging case to have the function of picking up sound signals. In this embodiment, an example is given with the sound collection circuit 10 being a sound collection microphone. Specifically, the sound collection microphone in the hearing aid charging case collects the sound signals of the television and converts the sound signals into electrical signals. The main control circuit 30 controls the communication circuit 20 to access the electrical signal of the sound collection microphone, and converts the electrical signal into a wireless signal and transmits it to the hearing aid through wireless communication technology.

[0036] In one embodiment, referring to Figure 2 , the number of the sound collection microphones is multiple, and the number of the input ends of the communication circuit 20 is multiple; the output end of each sound collection microphone is correspondingly connected to the input end of each communication circuit 20.

[0037] It can be understood that in order to enhance the effect of the sound collection microphone picking up ambient sound, in this embodiment, the number of the sound collection microphones is multiple, and the number of the input ends of the communication circuit 20 corresponds to the number of the sound collection microphones. The specific number can be optimized and adjusted according to actual usage needs. For example, taking the sound collection microphones including a first sound collection microphone, a second sound collection microphone, and a third sound collection microphone, and the communication circuit 20 including a first input end, a second input end, and a third input end as an example for illustration. Specifically, the first sound collection microphone, the second sound collection microphone, and the third sound collection microphone respectively pick up the sound signals of the sound-emitting unit and convert them into a first electrical signal, a second electrical signal, and a third electrical signal. The first electrical signal, the second electrical signal, and the third electrical signal are respectively output to the hearing aid through the first input end, the second input end, and the third input end of the communication circuit 20.

[0038] In one embodiment, referring to Figure 3, the hearing aid charging case further includes:

[0039] A power supply circuit 40, the controlled end of the power supply circuit 40 is connected to the control end of the main control circuit 30, and the output end of the power supply circuit 40 is connected to the sound collection circuit 10 and the communication circuit 20; the power supply circuit 40 is used to connect to the power supply end and access the voltage of the power supply end.

[0040] The main control circuit 30 is used to control the power supply circuit 40 to convert the voltage of the power supply end and then provide voltage to the sound collection circuit 10 and the communication circuit 20.

[0041] It can be understood that in this embodiment, the power supply circuit 40 is implemented by a rechargeable battery and a voltage converter. The input end of the voltage converter is connected to the output end of the rechargeable battery, and the voltage converter can convert the voltage output by the rechargeable battery into a fixed voltage to provide operating voltage for the sound pickup microphone and the Bluetooth device. For example, the rechargeable battery is a lithium battery, and the output battery voltage is 3.8V. The voltage converter is a DC-DC converter. The DC-DC converter can reduce the battery voltage to a fixed voltage of 1.5V and 3.3V for output. Among them, 1.5V is output to the sound pickup microphone to provide operating voltage for the sound pickup microphone; 3.3V is output to the Bluetooth device to provide operating voltage for the Bluetooth device.

[0044] The voltage stabilizing circuit 50 is used to perform voltage stabilizing processing on the output voltage of the received power supply module so that the voltage output to the sound collection circuit 10 and the communication circuit 20 is within the target range.

[0045] It can be understood that in this embodiment, the voltage stabilizing circuit 50 is implemented by a linear voltage regulator. The linear voltage regulator is connected in series between the power supply circuit 40 and the load circuit. The linear voltage regulator stabilizes the voltage output by the power supply circuit 40 within a target range through its internal circuit, and then outputs a stable voltage to the radio microphone and the Bluetooth device. The internal circuit of the linear voltage regulator mainly consists of an input filter circuit, a regulation circuit, and an output stage. Among them, the input filter circuit is used to filter out the noise and clutter in the voltage of the power supply circuit 40, so as to ensure the normal operation of the voltage regulator; the regulation circuit is used to regulate the voltage after overcurrent through a feedback mechanism to keep the output voltage within the target range; the output stage is used to output the regulated voltage to the radio microphone and the Bluetooth device respectively. For example, the linear voltage regulator stabilizes the voltage output by the power supply circuit 40 so that the voltage output to the radio microphone is between 1.3V and 1.7V. Preferably, in this embodiment, it can be 1.5V; the linear voltage regulator stabilizes the voltage output by the power supply circuit 40 so that the voltage output to the Bluetooth device is between 3.1V and 3.5V. Preferably, in this embodiment, it can be 3.3V.

[0047] A charging interface 60, which is used to connect to a power supply terminal and the power supply circuit 40; the charging interface 60 is used to establish a connection path between the power supply circuit 40 and the power supply terminal.

[0048] It can be understood that in this embodiment, the hearing aid charging case further includes a charging circuit. The charging circuit is connected in series between the charging interface 60 and the rechargeable battery, and is used to convert the power supply voltage into a fixed charging voltage to charge the rechargeable battery. In practical applications, when the rechargeable battery is a lithium battery, the power supply terminal outputs a power supply voltage to the charging circuit through the charging interface 60. The charging circuit performs step-up and step-down conversion on the power supply voltage and then outputs a 3.8V voltage to the lithium battery to charge the lithium battery.

[0049] The present invention also proposes a hearing aid device. Referring to Figure 3 , it includes a hearing aid and the hearing aid charging case as described above. The input end of the hearing aid is connected to the output end of the communication circuit 20.

[0050] It can be understood that the present utility model proposes a hearing aid device, which includes a hearing aid and a hearing aid charging case. By setting a microphone and a Bluetooth device on the hearing aid charging case, the hearing aid charging case is enabled to have the function of picking up sound signals.
