Description

Technical Field

[0001] The utility model relates to the field of hearing aids, in particular to a head-mounted bone conduction hearing aid with a volume adjustment function. Background Art

[0002] A head-mounted bone conduction hearing aid is a hearing aid that senses sound based on skull vibration. It can transmit sound directly to the inner ear through the bones, avoiding the discomfort that may be caused by traditional hearing aids. Bone conduction hearing aids transmit sound by vibrating bones. This method causes less damage to the inner ear and can better protect residual hearing.

[0003] Although modern technology has made head-worn bone conduction hearing aids lighter, the head-worn frame may still feel heavy to some users, especially when worn for long periods of time. This weight may cause discomfort, especially if there is extra pressure on the head or neck.

[0004] The head-mounted frame on existing head-mounted bone conduction hearing aids may not be able to adapt to users with different head shapes, which may lead to unstable wearing and easy shaking during activities, and will also cause the hearing aid body to shake together. The fit with the user's skull is low, and the hearing aid may slip or shift. Utility Model Content

[0040] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model is described clearly and completely. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0041] Reference Figure 1-Figure 5 , head-mounted bone conduction hearing aid with volume adjustment function, including:

[0042] Two hearing aid bodies 1 are used to be placed near the user's ears to receive sound signals; a control unit 2 is installed on the two hearing aid bodies 1 respectively; a connector 3 is installed between the two control units 2 and is used to connect and adjust the usage distance between the two hearing aid bodies 1 to adapt to the head sizes of different users; a winding wheel 201 is installed in the control unit 2 and connected to the connector 3. When the winding wheel 201 is configured to reel in the connector 3, the distance between the two hearing aid bodies 1 is shortened.

[0043] The connector 3 is made of a nylon rope or a nylon belt. The connector 3 connects the two hearing aid bodies 1, so that the bone conduction hearing aid can be adapted to users with different head shapes when worn, with a higher degree of adaptability and a smaller weight, so there is no excessive discomfort when wearing it. The connector 3 cooperates with the two ear hooks to be stably connected between the two ears. The user can adjust the distance between the two hearing aid bodies 1 according to the head size, thereby achieving personalized wearing and improving the wearing comfort and hearing aid effect.

[0044] Reference Figure 1 and Figure 2 The hearing aid body 1 includes: two fixing parts 101, which are respectively installed on the two hearing aid bodies 1, and are used to wear the hearing aid body 1 on the user's head; two vibrator parts 102, which are respectively installed at one end of the two fixing parts 101, and are used to convert sound signals into bone conduction vibrations; a control knob 104, which is installed on one side of the hearing aid body 1, and is used to manually adjust the volume of the hearing aid.

[0045] The fixing part 101 is used to wear the hearing aid body 1 on the user's head, and the vibrator part 102 converts the sound signal into bone conduction vibration to achieve effective transmission of sound. The setting of the control knob 104 enables the user to manually adjust the volume of the hearing aid to meet different hearing needs.

[0046] Reference Figure 2 The fixing part 101 includes: an anti-slip part 103, which is installed on the inner contour of the fixing part 101. Installing the anti-slip part 103 on the fixing part 101 can increase the friction between the fixing part 101 and the user's head, improve the wearing stability and safety, and prevent the hearing aid from slipping or shifting during use.

[0047] Reference Figure 3 , Figure 4 and Figure 5The control part 2 includes: a accommodating chamber, which is opened in the control part 2, and the winding wheel 201 is installed in the accommodating chamber; a groove, which is opened with the bottom wall of the accommodating chamber, and a first elastic member 202 is connected in the groove, one end of the first elastic member 202 is connected to the side wall of the groove, and the other end of the first elastic member 202 is connected to the winding wheel 201, and the first elastic member 202 is used to provide a reset force for the winding wheel 201; a ratchet 203, which is installed on the top of the winding wheel 201; a mounting seat 204, which is installed on the side wall of the accommodating chamber, and a mounting groove 205 is opened on one side of the mounting seat 204; a pawl 206, which is installed on the inner wall of the mounting groove 205, and the pawl 206 is connected to the ratchet 203; a second elastic member 207, which is installed on the side wall of the mounting groove 205 and connected to the pawl 206; a shaft rod 209 is connected to one side of the pawl 206, and one end of the shaft rod 209 passes through the accommodating chamber and extends to the outside of the control part 2 to be connected to the take-up wheel 208.

[0048] The first elastic member 202 is made of a stainless steel coil spring, and may also be an alloy coil spring. The second elastic member 207 is made of a spring, and may also be a spring sheet. The design of the control unit 2 takes into account the functions of adjustment and resetting, and realizes the winding and resetting of the connecting member 3. The arrangement of the ratchet 203, the pawl 206, the second elastic member 207 and the take-up wheel 208 enables the user to conveniently operate the winding and loosening of the connecting member 3, while also ensuring the resetting stability of the winding wheel 201.

[0049] Reference Figure 2 , a magnetic attraction component 105 is installed on the adjacent side surface of the two hearing aid bodies 1, which is used to attract the two hearing aid bodies 1 to each other when the hearing aids are idle. The magnetic attraction component 105 uses a neodymium iron boron magnet or a samarium cobalt magnet. The hearing aids can be attracted to each other when idle, which is convenient for carrying and storage, and reduces the occupied space.

[0050] During use, one of the hearing aid bodies 1 is pulled, and the hearing aid body 1 pulls the connecting member 3 out of the control unit 2. When the connecting member 3 is pulled, the winding wheel 201 rotates, and the winding wheel 201 drives one end of the first elastic member 202 to rotate. The first elastic member 202 accumulates force, and the winding wheel 201 also drives the ratchet 203 to rotate. The rotation of the ratchet 203 will continuously lift the pawl 206. After the distance between the two hearing aid bodies 1 is adjusted to a suitable position, the hearing aid body 1 is released, and the pawl 206 is locked on the ratchet 203. The position of the winding wheel 201 is locked in the tooth groove, and the hearing aid body 1 can be worn on the head using the two ear hooks, and the two ear hooks are hung on the auricle to stabilize the position of the hearing aid body 1. When the take-up wheel 208 is rotated, the shaft 209 rotates with the take-up wheel 208 and drives the pawl 206 to rotate actively. The pawl 206 disengages from the tooth groove on the ratchet 203, and the fixed restriction of the ratchet 203 can be cancelled. The first elastic member 202 releases the elastic force to help the winding wheel 201 return to the initial position, and the connecting member 3 can be rolled up.

[0051] In summary, compared with the prior art, the present invention has the following beneficial effects:

[0052] Through the control of the connector 3, it can be flexibly adjusted according to the head size of different users. The user can reel in or loosen the connector 3 according to his or her head shape by operating the take-up wheel 208, thereby adjusting the distance between the two hearing aid bodies 1 to ensure wearing comfort and stability, so that the hearing aid can adapt to the needs of different users and provide a personalized wearing experience.

[0053] By setting the first elastic member 202, when the user releases the hearing aid body 1, the winding wheel 201 can automatically reset to the initial position and reel in the connector 3, which not only makes it convenient for the user to store and carry the hearing aid, but also avoids the risk of clutter and damage to the head-mounted bone conduction hearing aid when it is idle.
