Description

Technical Field

[0001] The utility model relates to the field of hearing aids, in particular to a magnetically connected receiver external hearing aid. Background Art

[0002] The traditional bone conduction hearing aid vibrator is usually assembled by fixing the vibrator on the front cover, and then welding the connection line from the hearing aid body to the vibrator tin point, so as to connect the signal of the hearing aid body with the vibrator. After the vibrator is connected, the front cover is combined with the back cover connected to the hearing aid body. This assembly structure has the problems of cumbersome process and low efficiency, which affects the overall assembly speed and easily causes damage to the appearance.

[0033] The utility model discloses a magnetically connected receiver external hearing aid

[0034] Example 1 Figure 1-7 As shown:

[0035] A magnetically connected external hearing aid with a receiver includes a hearing aid host 1 and a receiver assembly 6. The main design is a receiver-mounted external hearing aid that can be easily installed and disassembled. The existing external hearing aid with a receiver is changed to a detachable metal contact type, which is simple and convenient. Moreover, after the receiver or the host body is damaged, new accessories can be directly and quickly replaced, instead of reporting the entire device for repair and requiring dismantling and repair. Quick connection does not require waiting time.

[0036] The hearing aid host 1 involved in the utility model is provided with a control circuit board 2, a microphone receiver 3 and a power supply component 4. A volume adjustment button 5 is provided on the side wall of the hearing aid host 1. The electronic components used in the hearing aid are mainly concentrated in the hearing aid host 1. There are two microphone receivers 3, which are respectively arranged on both sides of the volume adjustment button 5 of the hearing aid host 1.

[0037] In this embodiment, the hearing aid host 1 includes a hearing aid front shell 11 and a hearing aid rear shell 12. The power supply component 4 is arranged at the bottom end of the hearing aid front shell 11. The power supply component 4 includes a battery compartment 41 and a battery 42 arranged in the battery compartment. The battery compartment 41 is provided with a battery compartment cover 411. One end of the battery compartment cover 411 is rotatably connected to the hearing aid front shell 11 through a pin 412, and the other end of the battery compartment cover 411 is snap-connected to the hearing aid front shell 11. The battery 42 is generally a button battery. The battery 42 can be conveniently replaced with a new one by opening the battery compartment cover 411.

[0038] The main design point of the utility model is that the end of the hearing aid rear shell 12 is detachably connected to the receiver assembly 6, and the end surface of the hearing aid rear shell 12 is provided with a power supply terminal 13 and a fixing magnet 14;

[0039] An end cover 121 is provided on the end surface of the hearing aid rear shell 12 , and a receiving groove 120 is opened on the end cover 121 . The power supply terminal 13 is located in the receiving groove 120 . A connecting protrusion 631 corresponding to the shape of the receiving groove 120 is provided on the connecting end 63 .

[0040] like Figure 3-4 As shown: an end cover 121 is arranged on the end face of the rear shell 12 of the hearing aid. The end cover 121 is annular and can wrap and fix the connecting end 63. The fixing magnet 14 is arranged in the end cover 121. The end cover 121 is provided with a receiving groove 120. The power supply terminal 13 is in the receiving groove 120. A connecting protrusion 631 corresponding to the shape of the receiving groove 120 is arranged on the connecting end 63. The metal contact 64 and the adsorption magnet 65 are in the connecting protrusion 631. For the convenience of insertion, the cross-section of the receiving groove 120 is circular, and the whole is a circular groove. The connecting protrusion 631 is a cylinder. After the connecting protrusion 631 is snapped into the receiving groove 120, it is adsorbed together by the magnetic attraction of the fixing magnet 14 and the adsorption magnet 65 to improve the stability of the connection.

[0041] As a further improvement, the fixed magnet 14 is configured as two parallel magnets, so that the adsorption magnet 65 on the connection protrusion 631 can be distinguished and guided by the N pole and the S pole.

[0042] Specifically, the fixed magnet 14 includes an upper fixed magnet 141 and a lower fixed magnet 142, and the adsorption magnet 65 includes an upper adsorption magnet 651 and a lower adsorption magnet 652. The upper fixed magnet 141 and the upper adsorption magnet 651 are magnetically fixed, and the lower fixed magnet 142 and the lower adsorption magnet 652 are magnetically fixed.

[0043] like Figure 6As shown, when the connecting protrusion 631 is in the accommodating groove 120, in the vertical direction, the S or N poles of the upper adsorption magnet 651 of the upper fixed magnet 141, the lower fixed magnet 142 and the lower adsorption magnet 652 are all facing in one direction, wherein the N pole of the upper fixed magnet 141 and the N pole of the lower fixed magnet 142 are facing upward, and the N pole of the upper adsorption magnet 651 and the N pole of the lower adsorption magnet 652 are facing upward, thereby ensuring the uniqueness of the position, and ensuring that the power supply terminal 13 is aligned with the metal contact 64, and the connection is corrected by magnetic attraction. The magnetic connection with automatic correction function eliminates the need for users to plug and unplug, and the metal contact 64 contacts and conducts the hearing aid host 1 body and the speaker of the receiver 61, thereby avoiding the possible breakage of the direct plug connection.

[0044] like Figure 2-5 As shown: The utility model relates to a receiver assembly 6, which includes a receiver 61, a speaker wire 62 and a connecting end 63, one end of the speaker wire 62 is connected to the receiver 61, and the other end of the speaker wire 62 is connected to the connecting end 63, and a metal contact 64 and an adsorption magnet 65 are provided on the connecting end 63. After the metal contact 64 and the power supply terminal 13 are connected and energized, an electrical signal is sent to the receiver 61. The receiver 61 is detachably provided with an earplug 66, and the adsorption magnet 65 is fixed in cooperation with the fixed magnet 14.

[0045] like Figure 7 As shown: the main material of the earplug 66 is elastic material in order to improve comfort. If it falls off, it will affect the normal use of the hearing aid. The receiver 61 is snap-fitted with the earplug 66. A ring magnet 661 is provided in the earplug 66. The end of the receiver 61 is made of magnetic material. The traditional earplug 66 relies on brute force to snap onto the sound outlet of the receiver. However, since the patients using hearing aids are older patients, in order to avoid the problem of loose snapping, an additional ring magnet 661 is designed to be directly adsorbed on the receiver 61 to prevent the earplug 66 from falling off.

[0046] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0047] The above-mentioned embodiments only express several implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model shall be based on the attached claims.
