The technical conception of the invention is as follows: in the limited volume of headphone, make full use of the connection space between headphone's shell and the earmuff, through setting up the shell to open to increase annular rubber ring, thereby make the inner chamber that annular rubber ring and open shell enclose as the dilatation space, thereby with the back sound cavity space of loudspeaker increase loudspeaker of back sound cavity intercommunication, promote headphone's low frequency audio.

Fig. 1 to 2 show one embodiment of the headset of the present application, as shown in fig. 1 to 2, comprising: the ear muff 100, the shell 200, the loudspeaker 300 arranged in the shell 200 and the annular rubber ring 400.

The side of the shell 200 facing the earmuff 100 is open, the annular rubber ring 400 is arranged between the shell 200 and the earmuff 100 in a surrounding manner, the open area of the shell 200 is covered, the inner cavity enclosed by the annular rubber ring 400 communicated with the shell 200 is communicated with the rear sound cavity of the loudspeaker 300, so that the volume of the rear sound cavity is increased, and the low-frequency sound effect of the headset is improved.

As shown in fig. 1, most of the existing headphones are the same and limited by the volume of the headphones, and there is no way to provide an independent cavity for the horn 300, so that the horn 300 and other components such as a battery and a circuit board are designed together in the inner cavity of the housing 200, so that the rear sound cavity of the horn 300 only includes a narrow area from the rear of the horn 300 to the circuit board, and the volume of the rear sound cavity is difficult to achieve the ideal low-frequency sound effect requirement.

In the embodiment of the application, the upper end of the shell 200 is opened, and the annular rubber ring 400 is added at the connecting groove of the earmuff 100, so that the connecting space between the shell 200 and the earmuff 100 is utilized, the annular rubber ring 400 and the shell 200 enclose the expansion space of the rear acoustic cavity, the volume of the rear acoustic cavity of the loudspeaker 300 is increased, the low-frequency sound effect of the earphone is improved, the annular rubber ring 400 is arranged in the connecting groove of the shell 200 and the earmuff 100, the volume of the headset is not obviously increased, and the small size and portability of the headset are maintained.

In this embodiment, the headset further includes a connection bracket 500, and the connection bracket 500 has the effect of connecting the housing 200 and the earmuff 100, one end of which is installed in the housing 200, the other end of which is installed with the earmuff 100, and the annular rubber ring 400 surrounds the outer side of the connection bracket 500, so as to prevent the connection bracket 500 from being exposed, thereby maintaining a good appearance of the headset.

In this embodiment, the earmuff 100 is also rotatably adjustable relative to the shell 200 to provide increased comfort to the user. Specifically, a rotation shaft along the radial direction of the housing 200 is disposed in the housing 200, and one end of the connection bracket 500 is rotatably mounted in the housing 200 through the rotation shaft, so that the earmuff 100 mounted at the other end of the connection bracket 500 can rotate relative to the housing 200 to adjust the angle, so that the user wears the earmuff more flexibly and comfortably, and the earmuff is particularly suitable for sports coordination. In addition, the annular rubber ring 400 outside the connecting bracket 500 has flexibility and can deform along with the rotation of the connecting bracket 500, so that the angle adjustment of the earmuff 100 is not affected.

In the earphone design, the rear sound cavity of the horn 300 is also required to design the vent hole 410 so that the audio characteristics of the headphone are improved, and the size of the vent hole 410 is important for the stability of the audio characteristics. In the present embodiment, as shown in fig. 2, the annular rubber 400 is provided with a vent hole 410, and the vent hole 410 is provided at a position where the annular rubber 400 is aligned with the rotation shaft. Since the portion of the annular rubber ring 400 aligned with the rotation shaft is pressed little when the ear muff 100 is rotated and adjusted, the deformation is small and even no deformation is generated, so that the size of the vent hole 410 can be kept stable, and the audio characteristics of the headphone can be kept stable.

As shown in fig. 2, two air leakage holes 410 of the annular rubber ring 400 are symmetrically provided, and the two air leakage holes 410 are disposed in parallel with the rotation axis in the housing 200. In this embodiment, the rotation shafts in the housing 200 are also provided in two symmetrical pairs.

As shown in fig. 2, in this embodiment, the annular rubber ring 400 is further provided with a positioning post 420, and the positioning post 420 is connected to the housing 200 to prevent the annular rubber ring 400 from rotating relative to the housing 200, so as to keep the position of the air leakage hole 410 unchanged and always align with the rotation axis.

In this embodiment, the annular rubber ring 400 may be glued to make the annular rubber ring 400 adhere to the housing 200 and/or the ear muff 100, so as to ensure that other parts of the rear acoustic cavity except the air leakage hole 410 are airtight, and improve the stability of the structure of the rear acoustic cavity.

In this embodiment, the horn 300 is also mounted on the connection bracket 500, and the connection bracket 500 is opened at an end of the connection bracket 500 located in the housing 200, and the rear sound chamber of the horn 300 is communicated with the inner chamber of the housing 200. The loudspeaker 300 and the earmuff 100 are installed simultaneously through the connecting bracket 500, the assembly process is convenient, and the distance between the loudspeaker 300 and the earmuff 100 is kept unchanged, namely, the sound emitting distance between the loudspeaker 300 and the human ear is unchanged, so that the wearing experience effect of the headset is guaranteed, and the tone quality is stable.

In this embodiment, the headset further includes a mounting plate 600, and the earmuff 100 is mounted on the connection bracket 500 through the mounting plate 600, for example, may be adhered to the mounting plate 600 or sleeved on the mounting plate 600, which will not be described herein.

In the present embodiment, the housing 200 includes a front case 220 and a rear case 230 assembled together. When assembled, the connection bracket 500 may be penetrated from the rear of the front case 220 before the front case 220 and the rear case 230 are assembled, so as to be conveniently installed in the housing 200.

In this embodiment, the battery and circuit board 700 of the headset is disposed within the housing 200, behind the connection bracket 500, to make room for the speaker 300 at the front end of the headset housing 200.

The foregoing is merely a specific embodiment of the invention and other modifications and variations can be made by those skilled in the art in light of the above teachings. It is to be understood by persons skilled in the art that the foregoing detailed description is provided for the purpose of illustrating the invention more fully, and that the scope of the invention is defined by the appended claims.
