The utility model discloses an in-ear earphone refers to fig. 1 and 2, including earlap 100, loudspeaker 200 and earmuff 300, be formed with the inner chamber in the earlap 100, during loudspeaker 200 located the inner chamber, loudspeaker 200 separated into preceding sound chamber 130 and back sound chamber 140 with the inner chamber, and earlap 100 cup joints with earmuff 300, and the two cup joints position department and is formed with preceding pressure release passageway portion 400. One end of the front pressure release passage part 400 is communicated with the front acoustic cavity 130, and the other end of the front pressure release passage part 400 is communicated with the outside to release pressure to the front acoustic cavity 130. Referring to fig. 3 and 4, the pressure relief of the rear acoustic chamber 140 is accomplished through a rear sound venting hole 170 provided at the rear acoustic chamber 140, and the rear sound venting hole 170 communicates the rear acoustic chamber 140 with the outside. So, through the pressure release respectively to preceding sound chamber 130 and back sound chamber 140, make and can not produce pressure differential between preceding sound chamber 130 and the back sound chamber 140 to improve the acoustics and the sound quality of earphone, improve user experience.

Referring to fig. 2, the earshell 100 includes a socket 150 and a step 160 connected to the socket 150. The earmuff 300 is sleeved with the sleeving part 150 in an interference manner, so that the earmuff 300 is fixedly connected with the earmuff 100. In order to make the connection between the two more reliable, the glue dispensing process can also be carried out between the two. One end of the ear cap 300 abuts against the step part 160, and the step part 160 plays a certain stopping and limiting role for the ear cap 300, so that when the ear cap 300 is sleeved in the sleeve joint part 150, the ear cap moves to a specified position and cannot be sleeved continuously due to the stopping of the step part 160, and the assembly is facilitated. The front pressure release channel 400 is formed at the outer side of the sleeve-joint part 150 and the inner side of the ear cap 300, that is, by improving the structure of the ear cap 300 and the sleeve-joint part 150, the front pressure release channel 400 can be naturally formed at the connection position of the ear cap 300 and the sleeve-joint part 150 after the ear cap 300 and the sleeve-joint part 150 are connected, so as to release the pressure of the front acoustic cavity 130. Since the front pressure relief channel portion 400 is formed at the outer side of the ear shell 100, it is easy to process and implement.

The socket part 150 is preferably a cylindrical structure, and the position where the ear cap 300 is socket-connected with the socket part 150 is also preferably a cylindrical structure, so as to facilitate the matching socket-connection of the two. The step portion 160 preferably extends perpendicularly to the sleeve portion 150, so that when the ear cap 300 abuts against the step portion 160, the two can be perfectly attached without a gap, and the sealing performance and the structural reliability are improved.

The front pressure release channel part 400 is formed in two ways, one way is that a groove structure is arranged at the outer sides of the sleeve joint part 150 and the step part 160, and the front pressure release channel part 400 is formed by sleeve joint between the ear cap 300 and the sleeve joint part 150; the other is to provide a groove structure on the inner side of the ear cap 300, and form the front pressure relief channel part 400 by the sleeve connection between the ear cap 300 and the sleeve connection part 150. Two approaches are detailed below.

First, a groove structure is provided at the outer sides of the socket part 150 and the step part 160.

Specifically, referring to fig. 2 and 3, the sleeve-joint part 150 is provided with a first groove 410, the step part 160 is provided with a second groove 420, the first groove 410 is communicated with the second groove 420, and when the ear cap 300 is sleeved with the sleeve-joint part 150, and the end part of the ear cap 300 abuts against the step part 160, the inner side of the ear cap 300, the first groove 410 and the second groove 420 form the front pressure-releasing channel part 400. Since one end of the first groove 410 is communicated with the front acoustic cavity 130 and one end of the second groove 420 is communicated with the outside, the front pressure release channel part 400 communicates the front acoustic cavity 130 with the outside, thereby releasing the pressure of the front acoustic cavity 130.

Further, the first groove 410 extends along the X direction in which the ear cap 300 is sleeved in the sleeve-joint part 150, and the second groove 420 extends along the horizontal direction of the step part 160, so as to form an L-shaped front pressure-releasing channel part 400. Through optimizing the width, the depth, the length and other parameters of the first groove 410 and the second groove 420, the acoustic resistance in the front pressure relief channel part 400 can meet the acoustic requirement, and at the moment, the traditional tuning mesh cloth can be omitted from the front acoustic cavity 130, so that the cost and the assembly process are simplified. Meanwhile, the L-shaped front pressure relief channel portion 400 may prevent external dust, water drops, etc. from entering the front acoustic cavity 130 to affect acoustic performance.

Second, a groove structure is provided on the inner side of the ear cap 300.

Specifically, the position department that earmuff 300 and cup joint portion 150 cup jointed is equipped with the third recess, and the position department that earmuff 300 and step portion 160 leaned on is equipped with the fourth recess, and the third recess communicates with the fourth recess, and when earmuff 300 cup joints with portion 150, earmuff 300's tip and step portion 160 leaned on the back, pressure release channel portion 400 before outer side, third recess and the fourth recess of earmuff 100 will form. Since one end of the third groove is communicated with the front acoustic cavity 130 and one end of the fourth groove is communicated with the outside, the front acoustic cavity 130 is communicated with the outside through the front pressure relief channel part 400, and pressure relief of the front acoustic cavity 130 is realized.

Referring to fig. 2 and 4, the earmuff 100 includes a front shell 110 and a rear shell 120, and the front shell 110 and the rear shell 120 are fixedly connected by clipping to facilitate assembly. The horn 200 is fixedly connected with the front shell 110 by dispensing, and the front shell 110 is provided with a socket joint part 150 and a step part 160. The rear housing 120, the horn 200, and a portion of the structure of the front housing 110 collectively form the rear acoustic cavity 140. The partial structure of the front shell 110, the speaker 200, and the ear cap 300 together form the front acoustic chamber 130.

Referring to fig. 3 and 4, a rear sound venting hole 170 is provided on the front case 110 at the rear sound chamber 140, and the rear sound venting hole 170 communicates the rear sound chamber 140 with the outside to vent the rear sound chamber 140. In this embodiment, the rear sound venting hole 170, the first groove 410 and the second groove 420 for forming the front pressure venting channel 400 are both disposed on the front shell 110, and in actual processing, most of the functional structures and the mounting structures of the ear shell 100 are integrated on the front shell 110, so that the rear shell 120 does not need to be processed too much and is convenient to process and assemble.

The tuning net 500 is arranged at the rear sound leakage hole 170, the tuning net 500 is fixedly bonded with the inner side of the front shell 110, and the acoustic performance can be further improved through the tuning net 500.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
