Description

Technical Field

[0001] This application relates to the field of hearing equipment technology, and in particular to a hearing aid. Background Technology

[0002] Traditional custom-made Bluetooth hearing aids, due to limited internal space, can only place the Bluetooth antenna inside the casing. This means that when worn in the ear, the antenna is located inside the auricle, which is detrimental to Bluetooth signal transmission and reception. Some Bluetooth antennas are placed on the bottom of the hearing aid in a fishing line-like extension, but because the line is short and thin, the signal is still insufficient. Increasing the size of the casing can accommodate a larger antenna, but this reduces the product's ease of wear. Therefore, it is necessary to propose a hearing aid design that addresses the difficulty of antenna placement in traditional Bluetooth hearing aids. Utility Model Content

[0042] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0043] This application provides a hearing aid.

[0044] like Figure 1 As shown in one embodiment of this application, a hearing aid includes an instrument compartment 100, a support 200, a circuit board 300, a rod-shaped shell 400, and an antenna 500.

[0045] The instrument compartment 100 includes a first annular shell 110 and a second annular shell 120, which are fixedly connected to each other and have a smooth transition between them.

[0046] The support 200 includes a flexible body 210 and a flexible ring column 220. The flexible body 210 and the flexible ring column 220 are fixedly connected. The flexible body 210 is provided with a plurality of pressure relief holes 230. Each pressure relief hole 230 is arranged equidistantly around the central axis of the flexible body 210. The flexible body 210 and the flexible ring column 220 overlap each other. The flexible ring column 220 is disposed inside the flexible body 210. The inner circumferential surface of the flexible ring column 220 is attached to the outer circumferential surface of the first annular shell 110.

[0047] The circuit board 300 is disposed inside the second annular shell 120.

[0048] The rod-shaped shell 400 is fixedly connected to the second annular shell 120, and the rod-shaped shell 400 and the second annular shell 120 are in communication with each other.

[0049] The antenna sub-assembly 500 includes a first antenna portion 510 and a second antenna portion 520. The first antenna portion 510 is electrically connected to the circuit board 300, and the second antenna portion 520 is electrically connected to the circuit board 300. The first antenna portion 510 is attached to the second annular shell 120, and the second antenna portion 520 is disposed on the rod-shaped shell 400.

[0050] Specifically, in this embodiment, the customized Bluetooth hearing aid's instrument compartment 100 includes a first annular shell 110 and a second annular shell 120, with a large internal space to accommodate the circuit board 300. The first antenna portion 510 can be attached to the second annular shell 120, so that when worn in the ear, the antenna is located within the auricle, facilitating unidirectional transmission and reception of Bluetooth signals. The second antenna portion 520 is disposed within the rod-shaped shell 400, and the second antenna portion 520 extends in a fishing line-like shape, enabling the electric field vector to rotate spirally in space, thereby enhancing the signal. The support 200 can be inserted into the inner ear canal, thus supporting the instrument compartment 100.

[0051] This embodiment relates to a hearing aid. Through the second annular shell 120 of the instrument compartment 100, the hearing aid incorporates a circuit board 300. The circuit board 300 is electrically connected to the antenna 500, which facilitates the transmission and reception of Bluetooth signals. The circuit board 300 is a signal processing circuit that can meet the strong signal reception requirements when the hearing aid shell is customized according to different users' ear canal structures. The first annular shell 110 and the second annular shell 120 of the instrument compartment 100 are basically inside the auricle, while the rod-shaped shell 400 can extend downwards from the bottom of the ear, ensuring that the Bluetooth antenna is not blocked by the auricle structure, thereby obtaining better signal quality and increasing the Bluetooth communication distance. The support 200 includes a flexible body 210 and a flexible ring post 220, which are fixedly connected. The flexible body 210 is provided with multiple pressure relief holes 230, each of which is arranged equidistantly around the central axis of the flexible body 210. The flexible body 210 and the flexible ring post 220 overlap each other, and the flexible ring post 220 is located inside the flexible body 210. The inner circumferential surface of the flexible ring post 220 is attached to the outer circumferential surface of the ring-shaped shell, which makes the user feel similar to wearing ordinary Bluetooth headphones when wearing the hearing aid.

[0052] like Figure 2 As shown, in one embodiment of this application, the extension line of the central axis of the first annular shell 110 intersects the extension line of the central axis of the second annular shell 120. The angle between the extension line of the central axis of the first annular shell 110 and the extension line of the central axis of the second annular shell 120 is in the range of 110 degrees to 120 degrees.

[0053] Specifically, the extension line of the central axis of the first annular shell 110 intersects the extension line of the central axis of the second annular shell 120, and the first annular shell 110 and the second annular shell 120 can transition smoothly. The instrument chamber 100 can effectively block external environmental noise in a relatively enclosed environment. This reduces the output of audio mechanical energy, reduces the volume, and allows sound to be heard clearly at a relatively low volume.

[0054] In fact, the central axis of the second annular shell 120 is the equivalent central axis.

[0055] The angle between the extension of the central axis of the first annular shell 110 and the extension of the central axis of the second annular shell 120 is in the range of 110 to 120 degrees. This allows the instrument chamber 100 to conform to the shape of the ear canal after insertion, reducing the burden on the ear.

[0056] In one embodiment of this application, a wire-bearing wall 111 is provided on the side of the second annular shell 120 away from the first annular shell 110. The wire-bearing wall 111 is parallel to the extension line of the central axis of the second annular shell 120.

[0057] Specifically, the wire-bearing wall 111 provided in the second annular shell 120 allows the first antenna section 510 to be attached. With the first antenna section 510 attached to the wire-bearing wall 111 of the second annular shell 120, the antenna of the hearing aid is less likely to become tangled or knotted during use, which also helps to achieve a compact size for the hearing aid and enhances the signal receiving capability of the first antenna section 510.

[0058] like Figure 2 As shown, in one embodiment of this application, the central axis of the rod-shaped shell 400 is parallel to the central axis of the second annular shell 120. The rod-shaped shell 400 is disposed close to the bearing wall 111. The second annular shell 120 is disposed between the first annular shell 110 and the rod-shaped shell 400.

[0059] Specifically, the rod-shaped shell 400 is used to support the spiral-shaped second antenna section 520. The second antenna section 520 is located at the bottom of the second annular shell 120, extending out like a spiral fishing line. Because the fishing line is long and thin, it can enhance the signal. The second antenna section 520 can enhance the Bluetooth signal of the hearing aid and increase the Bluetooth communication distance.

[0060] like Figure 2 As shown, in one embodiment of this application, the antenna sub-array 500 includes one or more of linearly polarized antennas, circularly polarized antennas, and elliptical polarized antennas.

[0061] Specifically, the antenna sub-array 500 can be divided into linearly polarized antennas, which are further divided into vertically polarized antennas and horizontally polarized antennas. The electric field direction of the vertically polarized antenna is perpendicular to the ground, while the electric field direction of the horizontally polarized antenna is parallel to the ground. This is adapted to the first antenna section 510. The first antenna section 510 is attached to the wire-bearing wall 111 of the second annular shell 120.

[0062] Antenna sub-500 can be further divided into circularly polarized antennas and elliptically polarized antennas. The electric field vector of a circularly polarized antenna rotates spirally in space, and can be further divided into left-handed and right-handed circular polarization. The trajectory of the electric field vector of an elliptically polarized antenna is an ellipse, which is the general form of linear and circular polarization. This can be adapted to antenna sub-520.

[0063] like Figure 3 As shown, in one embodiment of this application, the circuit board 300 includes a microcontroller 310, a storage chip 320, and a power supply 330. The microcontroller 310 is electrically connected to the power supply 330. The storage chip 320 is electrically connected to the power supply 330. The microcontroller 310 is electrically connected to the antenna 500.

[0064] Specifically, the microcontroller 310 and the storage chip 320 enable the hearing aid's received information to be processed in the program of the storage chip 320, which can help the hearing aid improve the Bluetooth communication range.

[0065] In one embodiment of this application, the circuit board 300 further includes an amplifier circuit 340, a filter 350, and an oscillator 360. The filter 350 is electrically connected to the amplifier circuit 340. The oscillator 360 is electrically connected to the amplifier circuit 340. The amplifier circuit 340 is electrically connected to the power supply 330. The filter 350 is electrically connected to the microcontroller 310. The amplifier circuit 340 is electrically connected to the microcontroller 310.

[0066] Specifically, amplifier circuits are used to amplify the amplitude of the input signal. Filter circuits (350) are used to select or remove certain frequency components from the signal; common types include low-pass filters (350LPF), high-pass filters (350HPF), band-pass filters (350BPF), and band-stop filters (350BSF). Oscillator circuits are used to generate stable sine waves or other forms of periodic signals; common oscillator topologies include LC oscillators, which use a resonant circuit composed of inductors and capacitors to generate oscillations, and RC oscillators, which use a network of resistors and capacitors to determine the oscillation frequency.

[0067] In one embodiment of this application, the circuit board 300 further includes a modem 370. The modem 370 is electrically connected to the connection link between the amplifier circuit 340 and the oscillator 360. The second antenna section 520 is electrically connected to the amplifier circuit 340. The first antenna section 510 is electrically connected to the modem 370.

[0068] Specifically, modulation is the process of loading information onto a carrier wave, while demodulation is the process of recovering the original information from the modulated signal. Typical modulation methods include AM amplitude modulation, FM frequency modulation, and PM phase modulation, with corresponding differences in circuit topologies. For example, phase-locked loops (PLLs) are commonly used for FM demodulation.

[0069] The technical features of the above embodiments can be combined arbitrarily, and the execution order of the method steps is not restricted. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0070] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this application should be determined by the appended claims.
