[0025] It should also be noted that, in the embodiments of the present application, the same figure mark is used to represent the same component or the same part. For the same parts in the embodiments of the present application, the figure may only mark one of the parts or components as an example. It should be understood that the figure mark also applies to other identical parts or components.

[0026] See also Figure 1 In the first aspect, the embodiment of the present application provides a hearing aid. The hearing aid includes an earphone component 1 and a host 2, and the earphone component 1 is communicatively connected with the host 2. The host 2 is used to receive an external sound source and amplify the external sound source, and the earphone component 1 is used to receive the amplified external sound source and introduce it into the ear canal to make the human voice clearer, so as to help people with moderate hearing loss improve their hearing, and further improve the speech communication ability of people with moderate hearing loss.

[0027] Second, see Figures 1 to 3 The embodiment of the present application also provides an earphone assembly 1, which can be used in a hearing aid to connect to a host 2 of the hearing aid. It can be understood that in other embodiments of the present application, the earphone assembly 1 can also be used to connect to terminal devices such as mobile phones and computers to transmit audio to the ear canal, which is not the only limitation here.

[0028] The earphone assembly 1 includes two earphones 100 and an earphone wire 200 respectively connected to the two earphones 100, and the earphone wire 200 is connected to the host 2; the earphone 100 includes a shell 110, a speaker 120, a shielding frame 130 and a magnetic member 140, the speaker 120 and the magnetic member 140 are respectively installed in the shell 110, the speaker 120 is connected to the earphone wire 200, the magnetic member 140 is used to adsorb the two earphones 100 together, and the shielding frame 130 is installed in the shell 110 and isolates the speaker 120 and the magnetic member 140.

[0029] The speaker 120 is connected to the earphone cable 200 , and the earphone cable 200 is connected to the host 2 , so that the sound source received and amplified by the host 2 can be transmitted to the speaker 120 through the earphone cable 200 and transmitted to the ear canal through the speaker 120 .

[0030] The magnetic member 140 is disposed in the housing 110 . When the earphone assembly 1 is not in use, the two earphones 100 can be attracted to each other through the magnetic member 140 . The earphones 100 are fixed and the earphone wires 200 will not be entangled with each other.

[0031] The earphone assembly 1 provided in the embodiment of the present application has a magnetic member 140 in the housing 110 of the two earphones 100, so that when the earphone assembly 1 is not in use, the two earphones 100 can be attracted to each other through the magnetic member 140, so that the earphone wire 200 cannot be entangled through the earphone 100, thereby avoiding the user from spending a lot of time to sort out the entangled earphone wires 200 when using the earphone assembly 1, thereby improving the convenience of using the earphone assembly 1. At the same time, by arranging a shielding frame 130 between the speaker 120 and the magnetic member 140, the speaker 120 and the magnetic member 140 are isolated from each other, so that the magnetic field generated by the magnetic member 140 will not affect the sound quality of the speaker 120, ensuring that the speaker 120 produces clear sound quality.

[0032] In one embodiment, see Figure 3 , the distance d between the magnetic member 140 and the speaker 120 is greater than 0.8 mm. For example, the distance d between the magnetic member 140 and the speaker 120 may be 0.82 mm, 0.84 mm, 0.86 mm, 0.88 mm, 0.90 mm, 0.92 mm, 0.94 mm, 0.96 mm, 0.98 mm, 1.00 mm, etc. Of course, if the size of the entire earphone 100 allows, the distance d between the magnetic member 140 and the speaker 120 may be higher. In this embodiment, by limiting the minimum distance between the magnetic member 140 and the speaker 120, the influence of the magnetic member 140 on the speaker 120 can be minimized.

[0033] In one embodiment, see Figure 3 , the speaker 120 is installed at a position near the front end of the housing 110, and the magnetic member 140 is installed at a position near the rear end of the housing 110. The front end here refers to the end of the earphone 100 inserted into the earphone 100, and the rear end refers to the end of the earphone 100 exposed. The speaker 120 is arranged near the front end to facilitate the introduction of sound into the ear canal, and the magnetic member 140 is arranged near the rear end, so that the rear ends of the two earphones 100 can be adsorbed together, and the magnetic member 140 can also be arranged relatively far away from the speaker 120.

[0034] In one embodiment, see Figure 3, the housing 110 is formed with a mounting cavity 113, the shielding frame 130 is arranged in the mounting cavity 113 and divides the mounting cavity 113 into a front cavity 1131 and a rear cavity 1132, the speaker 120 is installed in the front cavity 1131, and the magnetic member 140 is installed in the rear cavity 1132. In this embodiment, the magnetic member 140 is also arranged in the mounting cavity 113, and the shielding frame 130 is also installed in the mounting cavity 113 to isolate the speaker 120 and the magnetic member 140. Such a configuration can reduce the number of cavities formed in the housing 110 and reduce the manufacturing cost of the housing 110. It can be understood that in other embodiments of the present application, a mounting groove can also be formed on the outer side of the housing 110, and the magnetic member 140 is embedded in the mounting groove, and the shielding frame 130 is installed in the mounting cavity 113; or, a through groove can also be formed on the surface of the housing 110, and the magnetic member 140 is embedded in the through groove, and the shielding frame 130 is installed in the mounting cavity 113, which is not limited here.

[0035] In one embodiment, see Figure 3 The housing 110 includes a front housing 111 and a rear housing 112, which are sealed and connected to form a mounting cavity 113; the speaker 120 is mounted on the front housing 111, and the outer peripheral wall of the shielding frame 130 is sealed and connected to the inner peripheral wall of the rear housing 112. In this embodiment, the housing 110 is divided into the front housing 111 and the rear housing 112, thereby facilitating the formation of the mounting cavity 113, and also facilitating the installation of the speaker 120, the shielding frame 130 and the magnetic member 140. In addition, the sealing of the mounting cavity 113 is ensured by sealingly connecting the front housing 111 and the rear housing 112, and the shielding effect of the shielding frame 130 on the magnetic member 140 is ensured by sealingly connecting the shielding frame 130 and the rear housing 112.

[0036] Specifically, the front shell 111 and the rear shell 112 are buckled and connected by a snap-fit ​​method, and finally glue is applied at the connection to ensure sealing and connection reliability. It can be understood that in other embodiments, the front shell 111 and the rear shell 112 can also be sealed and connected by a sealing ring, which is not limited here.

[0037] Specifically, the outer wall of the shielding frame 130 is sealed with the inner wall of the rear shell 112 by gluing, thereby preventing air leakage, isolating the magnetic member 140 and reducing noise. In addition, the shielding frame 130 can be made of any material that can isolate magnetism.

[0038] In one embodiment, see Figure 3The shielding frame 130 is formed with a support portion 131, which is used to support the magnetic member 140 to a certain height in the rear cavity 1132, so that the magnetic member 140 is separated from the speaker 120. Specifically, the support portion 131 and the inner side wall of the rear shell 112 jointly limit the magnetic member 140, so that the magnetic member 140 is firmly installed in the installation cavity 113.

[0039] In one embodiment, see Figure 3 , the rear shell 112 is formed with a mounting hole 1121, and the shielding frame 130 is formed with a wire hole. The mounting hole 1121 is used to mount the connector 400 of the headphone cable 200, and the wire hole is used to allow the wire connecting the headphone cable 200 and the speaker 120 to pass through. During assembly, the connector 400 of the headphone cable 200 is first installed in the mounting hole 1121 of the rear shell 112, and then the wire connected to the headphone cable 200 is passed through the wire hole to be welded to the speaker 120, so that the headphone cable 200 is electrically connected to the speaker 120. In this embodiment, by forming the mounting hole 1121 on the rear shell 112, the space of the front cavity 1131 can be reduced, thereby ensuring the sound quality of the speaker 120.

[0040] In one embodiment, see Figure 2 The front shell 111 is provided with a sound outlet, which is used to guide the sound source emitted by the speaker 120 to the ear canal. A first dustproof net 150 is installed at the sound outlet to block dust or other dirt to ensure the cleanliness of the front cavity 1131, thereby ensuring the sound effect of the earphone 100.

[0041] In one embodiment, see Figure 2 and Figure 3 The front end of the front shell 111 is also covered with an earmuff 160, which is made of soft rubber material and is used to be inserted into the ear canal. A through hole connected to the sound outlet is formed on the earmuff 160, and the sound source emitted by the speaker 120 can be introduced into the ear canal through the earmuff 160.

[0042] In one embodiment, see Figure 3 The rear shell 112 is formed with an air vent 1122, and a second dustproof net 170 is installed at the air vent 1122. The air vent 1122 can maintain the air pressure balance inside and outside the earphone 100, and prevent the air pressure inside the ear canal from being too high due to the excessive air pressure inside the earphone 100, thereby preventing the ear of the human body from feeling uncomfortable. In addition, the second dustproof net 170 can prevent external dust or other dirt from entering the installation cavity 113 from the air vent 1122.

[0043] In one embodiment, see Figure 1A line dividing buckle 300 is provided on the headphone cable 200, wherein the setting of the line dividing buckle 300 is conducive to the management of the headphone cable 200, and can also reduce the possibility of losing the headphone 100 or the hearing aid host 2.

[0044] In one embodiment, see Figure 1 and Figure 4 The earphone cable 200 is provided with a plug 500, and the host 2 is provided with a socket 21, and the plug 500 is electrically plugged into the socket 21. When in use, the plug 500 can be inserted into the socket 21, thereby forming a mechanical connection and an electrical connection between the earphone assembly 1 and the host 2; when not in use, the plug 500 can be separated from the socket 21, and charging can also be performed through the socket 21.

[0045] In one embodiment, see Figure 1 and Figure 4 The earphone 100 is an in-ear earphone 100, and the earphone 100 is connected to an earphone cable 200, and the earphone cable 200 is connected to the host 2, and a back clip 22 is provided on the back of the host 2. When in use, the earphone 100 can be inserted into the ear canal, and the host 2 can be clamped on the user's clothes through the back clip 22. In this embodiment, the earphone 100 and the host 2 are connected through the earphone cable 200. Since the earphone cable 200 between the earphone 100 and the host 2 is long enough, the host 2 can be installed at a position far away from the earphone 100, thereby reducing the ear load and reducing the impact of the host 2 on the ear. In addition, the in-ear earphone 100 can isolate a part of the external sound through the earmuff 160, so that the sound does not overflow, thereby improving the effect of the earphone 100 introducing the sound source.

[0046] In one embodiment, when the earphone assembly 1 is assembled, first, the earmuff 160, the front shell 111, the first dustproof net 150 and the speaker 120 are assembled to form a front cavity assembly, then, the earphone cable 200 and the circuit board in the plug 500 are welded and molded by a mold to form a cable assembly; then, the wire buckle 300 is installed on the earphone cable 200; then, the connector 400 of the earphone cable 200 is inserted into the mounting hole 1121 of the rear shell 112 and fixed with glue; then, the wire is passed through the wire hole of the shielding frame 130 to be welded to the speaker 120; then, the shielding frame 130 and the rear shell 112 are fixed with glue to fix the magnetic part 140 through the shielding frame 130 and the rear shell 112; finally, the rear shell 112 and the front shell 111 are clamped and fixed with glue to form the earphone assembly 1.

[0047] When assembling the hearing aid, one only needs to insert the plug 500 of the earphone assembly 1 into the socket 21 of the host 2 .

[0048] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application.
