[0023] In the description of the present invention, it should be understood that the terms "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0024] In the present invention, unless otherwise clearly defined and specified, the terms "installation", "connection", "fixation" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] Furthermore, those skilled in the art may combine and associate different embodiments or examples and features of different embodiments or examples described in this specification without mutual contradiction.

[0026] The following is combined with Figure 1-3 The technical solution of the utility model is further explained.

[0027] A headset with a feedback microphone, see Figure 1 , including a back cover 1, an ear cover 2 and a feedback microphone 3, wherein the ear cover 2 is detachably connected to the back cover 1, which facilitates the disassembly, replacement or maintenance of the two. The detachable connection between the two can adopt an existing conventional structure, which will not be described in detail here. Figure 2-Figure 3 The ear cover 2 is provided with a sound outlet channel 21 and a receiving groove 22, and a connecting channel 231 is provided between the sound outlet channel 21 and the receiving groove 22. One end of the sound outlet channel 21 is connected to the outside, and the sound-generating component in the earphone transmits sound outward through the sound outlet channel 21. The feedback microphone 3 is provided in the receiving groove 22, and the feedback microphone 3 is provided with a sound hole 31 for capturing the sound heard by the user. The sound hole 31 is connected to the sound outlet channel 21 through the connecting channel 231, so as to capture the sound heard by the user. Liquid silicone is filled between the feedback microphone 3 and the inner side wall of the receiving groove 22, and the feedback microphone 3 is fastened to the receiving groove 22 after the liquid silicone is cured.

[0028] The above earphones place the feedback microphone 3 in the receiving groove 22, and the feedback microphone 3 and the inner wall of the receiving groove 22 are filled with liquid silicone. After the liquid silicone is cured, the feedback microphone 3 is fastened in the receiving groove 22. The operation of installing the feedback microphone 3 is simple, which is conducive to improving the assembly efficiency. After the feedback microphone 3 is placed in the receiving groove 22, the space between the two is an irregular shape. Liquid silicone is used to fix the feedback microphone 3. The liquid silicone can fill the irregular space, which improves its assembly reliability. After curing, the liquid silicone has good elasticity, which can buffer the feedback microphone 3, reduce the vibration of the microphone and reduce noise.

[0029] See also Figure 1The earphone of this embodiment is a neck-hanging earphone, which also includes a collar 4, a functional cavity, a function key 5, etc. These are conventional structures and will not be described here. In order to improve the wearing effect, an earplug 6 is provided on the ear cover 2.

[0030] See also Figure 2-Figure 3 The side wall of the feedback microphone 3 with the sound hole 31 is abutted against the inner wall of the accommodating groove 22 close to the sound outlet channel 21. In this way, when filling with liquid silicone, the liquid silicone is not easy to be exposed from the accommodating groove 22, thereby preventing the liquid silicone from being exposed to the sound outlet channel 21 and solidifying to affect the sound effect and reduce the sound quality. It also prevents the liquid silicone from leaking into the sound hole 31 of the feedback microphone 3 and causing the sound hole 31 to be blocked.

[0031] Furthermore, a partition 23 is provided between the sound outlet channel 21 and the receiving groove 22, and the above-mentioned communication channel 231 is provided on the partition 23. By providing the partition 23, the contact area between the feedback microphone 3 and the receiving groove 22 is larger, further improving the sealing effect between the two, and preventing the leakage of liquid silicone.

[0032] Preferably, the groove is arranged in the middle position of the partition 23, and the sound hole 31 is opposite to the middle position of the groove. In this way, the overall structure of the entire ear cover 2 is compact. In addition, the feedback microphone 3 is not close to the edge of the groove. Even if a small amount of liquid silicone is exposed, the liquid silicone will not flow into the sound hole 31, causing the sound hole 31 to be blocked.

[0033] The partition 23 and the ear cover 2 are an integral structure, and the top thereof is concave downward to form a groove connecting the sound outlet channel 21 and the accommodating groove 22, and the groove is the above-mentioned connecting channel 231. The connecting channel 231 is set as a groove structure concave downward from the top of the partition 23, which is convenient for processing.

[0034] In this embodiment, the feedback microphone 3 is a silicon microphone. The silicon microphone is small in size, which makes it easy to assemble it into the ear cover 2 of a smaller volume. At the same time, it has strong stability, which is conducive to improving the use effect.

[0035] Obviously, the above embodiments of the utility model are only examples for clearly explaining the utility model, and are not intended to limit the implementation methods of the utility model. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is not necessary and impossible to list all the implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the utility model should be included in the protection scope of the claims of the utility model.
