[0002] A hearing aid is an assistive device designed for the hearing-impaired to help them improve their hearing and their ability to communicate with others. An in-ear hearing aid is a hearing aid that is fully or partially embedded in the ear canal. It is designed to provide greater concealment and comfort and is suitable for users with moderate to severe hearing loss.

[0003] In order to achieve the purpose of noise reduction, basic ear canal embedded hearing aids generally adopt the form of installing ear caps, which are inserted into the user's ear canal to ensure that the sound is well transmitted to the user's ear canal after hearing aid conversion. However, the shape of the user's ear canal is often different for different users. The applicability of basic ear caps is generally poor and they are prone to looseness. Sound can easily leak out through the gaps, affecting the sound clarity. When the earplugs do not match the ear canal, the risk of falling off and being lost will also increase.

[0004] In summary, an ear canal embedded hearing aid is proposed to solve the above problems. Utility Model Content

[0030] Example 1

[0031] Reference Figures 1 to 5 This embodiment provides an in-ear hearing aid, including a carrier assembly 100, which includes a first packaging shell 101, a second packaging shell 102, and a filter 103. A signal processing component 101b and a lithium battery 101f are respectively installed inside the first packaging shell 101. The signal processing component 101b includes a signal amplifier 101b-1, a filter 101b-2, and a central processing unit 101b-3. A micro air pump 101a, a control switch 101c, a potentiometer 101d, and a microphone 101e are respectively installed on the right side of the first packaging shell 101. The left end of the micro air pump 101a is connected to an air supply pipe 101a-1. A receiver 102a is fixedly installed on the left side of the second packaging shell 102.

[0032] Furthermore, the second packaging shell 102 is located on the left side of the first packaging shell 101 , and the right side of the second packaging shell 102 is engaged with the left side of the first packaging shell 101 .

[0033] Furthermore, the filter 103 is fixedly mounted on the left end of the receiver 102a, and the output end of the microphone 101e is electrically connected to the input end of the signal amplifier 101b-1.

[0034] Furthermore, the output terminal of the lithium battery 101f is electrically connected to the input terminal of the central processing unit 101b-3, and the signal amplifier 101b-1, the filter 101b-2 and the central processing unit 101b-3 are electrically connected in sequence.

[0035] Furthermore, the input terminals of the micro air pump 101a, the receiver 102a and the potentiometer 101d are all electrically connected to the output terminal of the central processing unit 101b-3.

[0036] It also includes an expansion and anti-slip component 200, which is mounted on the receiver 102a. The expansion and anti-slip component 200 includes a rubber sleeve 201, and a rubber ring 201a is fixedly connected to the right side of the surface of the rubber sleeve 201. A hollow rubber ring 201a-1 is installed at the center of the outer ring of the rubber ring 201a, and the inner cavity of the hollow rubber ring 201a-1 is connected to the transmission tube 201a-1a.

[0037] Furthermore, one end of the transmission tube 201a-1a away from the hollow rubber ring 201a-1 passes through the rubber ring 201a, and one end of the air delivery tube 101a-1 away from the micro air pump 101a is connected to the right end of the transmission tube 201a-1a by a socket connection.

[0038] Furthermore, the inner ring of the rubber sleeve 201 is in anti-slip contact with the surface of the receiver 102a, and the rubber ring 201a is arranged in an arc shape.

[0039] Furthermore, a micro pressure relief valve 201a-1b is fixedly installed in the inner cavity of the hollow rubber ring 201a-1, and the surface of the hollow rubber ring 201a-1 is fixedly connected to the connection between the outer ring of the rubber ring 201a.

[0040] Furthermore, the outer ring of the hollow rubber ring 201a-1 is fixedly inlaid with anti-slip strips 201a-1c. The number of anti-slip strips 201a-1c is several and evenly distributed on the hollow rubber ring 201a-1.

[0041] Furthermore, the center of the surface of the rubber ring 201a is recessed, and the hollow rubber ring 201a-1 is fixedly mounted on the recessed groove of the rubber ring 201a.

[0042] In actual application, in order to prevent the gas from flowing back in the gas pipe 101a-1, a one-way valve is installed on the gas pipe 101a-1, and the flow direction of the one-way valve is from the micro air pump 101a to the transmission pipe 201a-1a.

[0043] It should be noted that by providing the signal amplifier 101b-1 and the filter 101b-2, the signal transmitted by the microphone 101e can be amplified and filtered to ensure signal quality and stability. By providing the microphone 101e and the receiver 102a, the microphone 101e can capture external sounds and convert the sounds into electrical signals and transmit them to the signal amplifier 101b-1. The receiver 102a converts the electrical signals transmitted by the central processor 101b-3 into sounds. By providing the filter 103, a filtering protection function can be achieved to prevent dandruff in the user's ear canal from entering the interior of the receiver 102a. By providing the rubber sleeve 201 and the rubber ring 201a, the outer ring of the receiver 102a can be protected in the installed state to prevent the receiver 102a from directly contacting the dandruff in the ear canal and allowing it to contact the ear wall. The invention increases friction and has an auxiliary anti-slip effect. By providing a hollow rubber ring 201a-1, it can contact the ear wall in an expanded state according to different ear canal shapes, thereby achieving the purpose of increasing wearing stability and avoiding sound leakage. By providing a transmission tube 201a-1a and an air delivery tube 101a-1, gas can be introduced into the hollow rubber ring 201a-1 when the micro air pump 101a is working in the installed state. By providing a micro pressure relief valve 201a-1b, when the air pressure in the hollow rubber ring 201a-1 is high, excess gas can be automatically discharged, thereby avoiding excessive expansion of the hollow rubber ring 201a-1 and affecting wearing comfort. By providing an anti-slip strip 201a-1c, the hollow rubber ring 201a-1 can contact the user's ear canal in the expanded state, which can further increase contact friction and improve wearing stability.

[0044] During use, the user inserts the expansion anti-slip component 200 into the ear canal, and the rubber sleeve 201 and the rubber ring 201a contact the inner wall of the ear canal to complete the anti-slip wearing. Then, the microphone 101e captures the external sound and converts it into an electrical signal. After amplification and filtering by the signal amplifier 101b-1 and the filter 101b-2, the signal is transmitted to the receiver 102a through the central processor 101b-3, and the receiver 102a converts it into sound for the user to listen to. In actual use, when the rubber sleeve 201 and the rubber ring 201a are in contact with the inner wall of the ear canal, the user can wear the earphone without slipping. When the rubber ring 201a fails to make good contact with the ear wall and becomes loose, falls off, or the sound is misaligned due to gaps, the user can control the micro air pump 101a to work after wearing it. The gas flows into the hollow rubber ring 201a-1 through the air pipe 101a-1 and the transmission pipe 201a-1a. The hollow rubber ring 201a-1 gradually expands and contacts the ear wall, ensuring wearing stability. In addition, the hollow rubber ring 201a-1 is made of a flexible material and can be well adapted to the different ear canals of different users, which is more in line with actual usage needs.

[0045] It should be noted that the devices used, such as the receiver 102a, the central processing unit 101b-3, the signal amplifier 101b-1, the filter 101b-2, the micro air pump 101a, etc., as well as the transmission or control methods between the devices are all existing technologies and will not be described in detail here.

[0046] In summary, by providing the micro air pump 101a, the air supply tube 101a-1 and the expansion and anti-slip component 200, when actually worn, the expansion and anti-slip component 200 can penetrate into the user's ear canal, and the rubber sleeve 201 and the rubber ring 201a can contact the ear wall. When there are large differences in the ear canals of different users or stable wearing is required, the micro air pump 101a can be controlled to work, so that the gas enters the hollow rubber ring 201a-1 through the air supply tube 101a-1 and the transmission tube 201a-1a, so that the hollow rubber ring 201a-1 gradually expands and contacts the ear wall, completing the anti-slip expansion, ensuring the wearing stability of the bearing component 100, and ensuring the clarity of the sound after conversion by the receiver 102a.
