Description

Technical Field

[0001] The utility model relates to a hearing aid, in particular to a transmission antenna for Bluetooth signals of a hearing aid. Background Art

[0002] Hearing aids are devices used to enhance sound perception for people with hearing loss. They improve hearing by amplifying external sounds, helping users hear conversations and ambient sounds more clearly. Currently, hearing aids are equipped with a Bluetooth transmission antenna to facilitate timely reception of audio signals from mobile phones or other devices. This antenna, in conjunction with circuitry, enables signal transmission between the device and the Bluetooth hearing aid. By receiving and transmitting signals in the same frequency spectrum between the phone or other device and the hearing aid, audio input and output are achieved, providing a more convenient and flexible listening experience.

[0003] Currently, due to the small size of hearing aids, the antenna area is also significantly limited. Signal transmission at the hearing aid wearing location is affected by the dielectric properties of human tissue, which can change the antenna's equivalent inductance and capacitance, easily causing frequency shifts and other phenomena, resulting in signal distortion and attenuation, affecting the wearer's ability to hear. For these reasons, it is necessary to design a Bluetooth signal transmission antenna that has high efficiency and minimizes the electrical impact of human skin on the antenna. Utility Model Content

[0004] In view of the above-mentioned problems existing in the prior art, the purpose of the present utility model is to provide a transmission antenna for Bluetooth signals of hearing aids, which realizes the wide coverage of the Bluetooth signal transmission antenna on the hearing aid, avoids the influence of human skin on the electrical properties of the antenna, and improves the efficiency of Bluetooth signal transmission.

[0005] To achieve the above purpose, the technical solution of this utility model is as follows:

[0006] A hearing aid Bluetooth signal transmission antenna includes a hearing aid housing, a Bluetooth receiver, and an integrated module disposed on the hearing aid housing and connected to the Bluetooth receiver. The hearing aid housing is provided with a through hole on the circumference thereof for the Bluetooth receiver to pass through. A protective module is provided on the integrated module. A special-shaped antenna connected to the Bluetooth receiver is provided inside the hearing aid housing. Both sides of the top of the special-shaped antenna are provided with curved portions for keeping away from human skin and improving the transmission efficiency of the Bluetooth signal.

[0007] Preferably, the receiving end of the Bluetooth receiver is located outside the hearing aid housing.

[0008] Preferably, the length of the arc portion is greater than the length of the special-shaped antenna.

[0009] Preferably, the protection module comprises a white light away from the wearing end of the hearing aid housing, and a heat-sensitive component arranged in the hearing aid housing and connected to the white light and the protection module.

[0010] Preferably, an alarm is provided on one side of the protection module, a control switch is provided on one side of the alarm, and the control switch is connected to a white light.

[0011] Preferably, the thermal component includes a thermal conductive sheet arranged on the hearing aid housing near the wearing end, a supporting sheet is arranged on the peripheral side of the thermal conductive sheet, and a thermal sensor is arranged on the thermal conductive sheet.

[0012] Compared to existing technologies, the hearing aid Bluetooth signal transmission antenna provided by this utility model can increase the reception area and transmission range of the transmitted signal, prevent the influence of human skin on the transmitted signal, improve the transmitted sound quality, and enhance signal transmission efficiency. Specifically, the configuration of the special-shaped antenna and the curved ends on both sides can expand the antenna's coverage area within the existing space of the hearing aid. The placement of the Bluetooth receiver at the top of the hearing aid's peripheral side can prevent the influence of human skin on the antenna's electrical properties, expand the transmission area and transmission range of the Bluetooth signal, and improve the transmission efficiency of the transmission antenna.

[0013] In addition, through the use of the protection module, it can be used in conjunction with the thermal component, alarm and control switch. Through the use of the thermal sensor in the thermal component, the temperature of the transmission antenna can be detected in real time, which is convenient for the data processing and judgment of the integrated module and the protection module. The alarm is used for sound reminders and the white light is used for signal reminders, which makes it convenient for users to remove the hearing aids in time for heat dissipation, ensure the stable transmission of the transmission antenna signal, improve the user's hearing quality, improve the use effect of the transmission antenna, and is beneficial to the use of the Bluetooth function of the hearing aid.

[0023] In order to make the purpose, technical solutions and advantages of the embodiments of the present disclosure more clear, the embodiments of the present disclosure are described in more detail below in conjunction with the drawings of the embodiments. Note: The described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0024] As attached Figures 1 to 3 As shown, an embodiment of the present invention provides a hearing aid Bluetooth signal transmission antenna, which is used for transmitting and receiving Bluetooth signals of the hearing aid. The integrated module 12 of the transmission antenna is connected to the storage power supply of the hearing aid. The integrated module 12 is provided with a Bluetooth transmission unit and a Bluetooth receiving unit for use with Bluetooth signals. The hearing aid housing 1, the Bluetooth receiver 11 and the integrated module 12 connected to the hearing aid housing 1 and the Bluetooth receiver 11 are provided. The peripheral side of the hearing aid housing 1 is provided with a through hole for the Bluetooth receiver 11 to pass through. The integrated module 12 is provided with a protective module 5. The hearing aid housing 1 is provided with a protective module 5. The special-shaped antenna 4 connected to the Bluetooth receiver 11 has curved portions 41 on both sides of the top, which are used to keep away from human skin and improve the transmission efficiency of the Bluetooth signal. When the hearing aid is used, the end of the hearing aid with the earplug is worn on the user's ear. The Bluetooth receiver 11 is located on the peripheral side of the hearing aid housing 1 and is set away from the patient's skin to avoid contact between the Bluetooth receiver 11 and the user's ear. In addition, the use of the special-shaped antenna 4 and the curved portion 41 not only expands the transmission area of the Bluetooth signal, but also expands the transmission range, improves the receiving efficiency of the transmission antenna, and improves the quality of the transmitted sound.

[0025] In order to better avoid the contact between the transmission antenna and human skin, such as Figure 3 As shown, the transmission antenna sets the Bluetooth receiver 11 on the top outside of the hearing aid housing 1 so that it does not contact the wearer's skin, reducing the impact of the transmission antenna contacting the skin on the electrical properties of the Bluetooth signal and avoiding frequency deviation and attenuation of the antenna signal.

[0026] In order to receive Bluetooth signals in a wider range, such as Figure 3 and 4 As shown, the length of the arc portion 41 can be set to be greater than the length of the special-shaped antenna 4, and the arc portion 41 is sleeved on the outside of the electronic components in the hearing aid, so that it can make full use of the smaller space in the hearing aid to expand the signal receiving area of the Bluetooth antenna, more comprehensively receive and send antennas transmitting in different directions and ranges, and improve the transmission efficiency of the transmission antenna.

[0027] In order to better realize the transmission of Bluetooth signal, such as Figures 2 to 5 As shown, a white light 2 can be set on the hearing aid housing 1, and a thermal component 3 can be set in the hearing aid housing 1. Then, the white light 2 and the thermal component 3 are connected to the protection module 5 to construct a thermal protection circuit. The thermal component 3 detects the heat in the hearing aid housing 1 in real time, and the detection data can be transmitted to the protection module 5 of the integrated module 12. The module judges the data. When the data reaches the alarm value, the white light 2 can be turned on to light up as a reminder, so that the protection module 5 can remind the user and external personnel of the hearing aid heat dissipation through the light source, ensure the proper and stable operation of the hearing aid, reduce the impact of high temperature on the transmission signal, and increase the transmission stability of the Bluetooth signal, which is practical.

[0028] Further implementation of the protection module 5 to the hearing aid protection reminder, can use sound and light to remind the user, such as Figure 3 and 5 As shown, an alarm 51 can be set on one side of the protection module 5, and the temperature value of the normal operation of the hearing aid can be set in the protection module 5 as the thermal alarm value. When the thermal data transmitted in the protection module 5 is greater than the thermal alarm value, the alarm 51 can be triggered to give an alarm reminder, and the user can be reminded by sound that the hearing aid signal is poor and needs to be cooled. The control switch 52 can be triggered to light up the white light 2, which is convenient for external personnel to remind the user to turn off the hearing aid cooling in time, ensure the stable transmission of the Bluetooth signal, and improve the transmission sound quality; and the white light is more convenient for naked eye observation, ensuring the timeliness of the reminder.

[0029] Among them, it is worth mentioning that Figure 3As shown, the thermal assembly 3 consists of a heat conductive sheet 31, a support sheet 32, and a thermal sensor 33, and the thermal sensor 33 is connected to the protection module 5. The use of multiple support sheets 32 and the thermal assembly 3 facilitates the addition of a thermal protection function to the transmission antenna, ensuring an excellent working environment for the transmission antenna and improving signal transmission efficiency. The use of multiple support sheets 32 facilitates the creation of a gap between the hearing aid components and the housing, dissipating heat inside the hearing aid housing 1, and facilitates the transmission of heat from the receiving heat source to the thermal sensor 33 for heat detection. The sensor's signal transmission technology is then applied to transmit the detected signal via a signal line to the protection module 5 of the integrated module 12 for data analysis, providing conditions for the use status of the protection module 5 and increasing the accuracy of the protection module's use. In addition, if the thermal sensor 33 suddenly cools down during use, it can also trigger the alarm 51 or the white light 2 to issue an alarm reminder, conveniently reminding the user that the hearing aid has fallen and facilitating the retrieval of the hearing aid.

[0030] Of course, the above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
