[0028] The following will be combined Figure 1-Figure 3 , the structure of this embodiment is further described.

[0029] Example

[0030] See Figure 1-Figure 3 , this embodiment discloses a receiver assembly 1, comprising a transparent ear cap 11, a housing 12, a photosensor 13 and a receiver 14;

[0031] A sound outlet 115 is provided inside the transparent ear cap 11 to transmit sound to the ear canal;

[0032] The housing 12 is connected to the ear cap 11 and communicates with the sound outlet 115. A transparent portion is provided on the housing 12 to allow external light to enter the housing 12 through the transparent portion. The transparent portion is at least partially located inside the transparent ear cap 11.

[0033] The photosensor 13 is located inside the housing 12. External light is incident on the photosensor 13 through the transparent portion. When the transparent ear cap 11 is outside the ear, the photosensor 13 has a first light signal intensity. When the transparent ear cap 11 is inside the ear, the photosensor 13 has a second light signal intensity. The second light signal intensity is less than the first light signal intensity.

[0034] The receiver 14 is located inside the housing 12 and is used for producing sound. The sound signal outputted from the output end of the receiver 14 is transmitted to the ear canal through the sound outlet 115 .

[0035] Among them, the input end of the receiver 14 is used to be electrically connected to the gain amplifier, and the gain amplifier is arranged outside the shell 12, for amplifying the received sound signal and outputting it. When the ear cap 11 is in the in-ear state, the gain amplifier enters the on state, and when the ear cap 11 is outside the ear state, the gain amplifier enters the off state, that is, the gain amplifier can be turned on or off according to the change of the light signal intensity of the photosensor 13. When it is monitored that the photosensor 13 has a first light signal intensity, the gain amplifier is turned off, and when the photosensor 13 has a second light signal intensity, the gain amplifier is normally turned on.

[0036] The ear cap 11 is made of transparent material, which can ensure that the light sensor 13 can effectively receive external light, and the light is incident on the transparent part of the housing 12 through the transparent ear cap 11 and incident on the light sensor 13 through the transparent part;

[0037] The photosensor 13 may be fixed to the receiver 14 or to the housing 12 .

[0038] In the above structure, the photosensor 13 is used to detect changes in light. When the transparent ear cap 11 is not put into the ear, a large amount of external light enters the photosensor 13 through the transparent part. At this time, the light signal intensity received by the photosensor 13 - the first light signal intensity is relatively strong. When the transparent ear cap 11 is put into the ear, the transparent part is blocked, and only a small part of the external light enters the photosensor 13. At this time, the light signal intensity received by the photosensor 13 - the second light signal intensity is relatively weak. Therefore, according to the change in the light signal intensity of the photosensor 13, it is possible to judge whether the ear cap 11 is in the ear. When the ear cap 11 is in the in-ear state, the gain amplifier is controlled to turn on to realize the normal sound amplification function, and the hearing aid is in normal working state; when the ear cap 11 is not in the ear (not worn), the gain amplifier is controlled to turn off, which can effectively avoid the occurrence of howling, improve the user's experience, and also avoid the receiver 14 from being damaged by howling, thereby ensuring its service life.

[0039] In the above structure, placing the receiver 14 inside the ear cap 11 can make the receiver 14 closer to the eardrum, thereby achieving a higher sound pressure level.

[0040] like Figure 3 As shown, in some embodiments, the housing 12 includes a front shell 121 and a rear shell 122 , the front shell 121 has an extension portion 1211 , the extension portion 1211 is snapped into the interior of the ear cap 11 , and the transparent portion is disposed on the front shell 121 .

[0041] Furthermore, a slot 111 is provided inside the ear cap 11, and a protrusion 1212 is provided on the periphery of the extension portion 1211. The protrusion 1212 is engaged in the slot 111 to improve the connection reliability between the ear cap 11 and the front shell 121 and prevent it from loosening.

[0042] Among them, the ear cap 11 is made of a flexible material such as silicone. When connecting the front shell 121 and the ear cap 11, you only need to put the ear cap 11 on the front shell 121 and make the protrusion 1212 on the front extension part 1211 be inserted into the corresponding slot 111 inside the ear cap 11.

[0043] Furthermore, the front shell 121 is a transparent shell, that is, the entire front shell is made of transparent material.

[0044] In some embodiments, the rear shell 122 is a non-transparent shell, that is, the rear shell 122 is made of non-transparent material, so that when the ear cap 11 is placed in the ear, the photosensor 13 receives as little external light as possible, thereby better ensuring the sensitivity and accuracy of detection.

[0045] In some embodiments, the front shell 121 and the rear shell 122 may be connected by an adhesive, or may be connected in a detachable manner, such as a snap connection.

[0046] like Figure 3 As shown, in some embodiments, the ear cap 11 includes a second cap portion 113 and a first cap portion 112 sequentially arranged along the axis direction of the sound outlet 115 , and the axes of the second cap portion 113 and the first cap portion 112 coincide with each other.

[0047] Furthermore, the second cap body portion 113 and the first cap body portion 112 both include a cylindrical body portion 114, the diameter of which increases from the front end to the rear end, and the diameter D2 of the rear end of the second cap body portion 113 is larger than the diameter D1 of the rear end of the first cap body portion 112, so as to maintain better contact with the auricle to avoid loosening, while also ensuring a sealing effect after entering the ear and reducing sound leakage.

[0048] Preferably, the length L2 of the second cap body portion 113 is greater than the length L1 of the first cap body portion 112 to better adapt to the shape and structure of the auricle.

[0049] In some embodiments, the rear shell 122 is located outside the ear cap 11 .

[0050] In some embodiments, the light sensor 13 may be a photoresistor.

[0051] like Figure 1-Figure 2 As shown, this embodiment also discloses a hearing aid device, including a host component 3 and the above-mentioned receiver component 1;

[0052] The host component 3 includes a casing 31, which is located outside the shell 12. A main control circuit board, a microphone and a gain amplifier are arranged inside the casing 31. The microphone, gain amplifier, receiver and photosensor 13 are all electrically connected to the main control circuit board. The main control circuit board receives the light signal transmitted by the photosensor 13 and controls the gain amplifier to turn on or off according to the light signal.

[0053] Specifically, the photosensor 13 is used to monitor the light signal and transmit the light signal to the main control circuit board; the main control circuit board controls the gain amplifier to turn on or off according to the light signal intensity of the photosensor 13, so that when the photosensor 13 detects the first light signal intensity, the gain amplifier is controlled to turn off, and when the second light signal intensity is detected, the gain amplifier is controlled to turn on normally.

[0054] The sound collected by the microphone is amplified by the gain amplifier and then output to the receiver 14 , and then transmitted to the ear canal by the receiver 14 .

[0055] In some embodiments, the housing 31 and the shell 12 are connected by a wire tube 2, and multiple wires are arranged in the wire tube 2. The receiver 14 is electrically connected to the gain amplifier through the corresponding wires, and the photosensor 13 is electrically connected to the main control circuit board through the corresponding wires to realize the transmission of optical signals.

[0056] The above-mentioned hearing aid structure can effectively monitor whether the ear cap of the hearing aid is placed in the ear through a photosensitive sensor. After the hearing aid is turned on, if it is detected that the ear cap is not placed in the ear, the gain amplifier is kept off to avoid howling. When the ear cap is detected to be placed in the ear, the gain amplifier is turned on, allowing the hearing aid to enter a normal working state, thereby greatly improving the wearer's experience, while also avoiding howling that causes damage to the receiver. It also helps to save power consumption and increase battery life.

[0057] All of the above optional technical solutions can be combined in any way to form optional embodiments of the present invention, that is, any multiple embodiments can be combined to meet the needs of different application scenarios. They are all within the scope of protection of this application and will not be described in detail here.

[0058] It should be noted that the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
