In the present embodiment, the equalizing member 3 may be disposed at a predetermined angle, for example, at an inclination, with respect to the horn assembly 2, so that the equalizing member 3 is deviated from the horn assembly 2 toward one side of the horn assembly 2 from the extending direction of the horn assembly 2 to the inner wall of the housing 1. Specifically, one side of the pressure equalizing member 3 is disposed on the speaker assembly 2, and the other side opposite to the other side extends toward the inside of the housing 1, that is, the extending direction is the direction extending from the speaker assembly 2 toward the inner wall of the housing 1. Here, the deviation of the horn assembly 2 toward one side of the horn assembly 2 means the deviation of the horn assembly 2 toward the outside of the front sound cavity 111, or the deviation of the horn assembly 2 toward the outside of the rear sound cavity 112, in other words, the deviation of the horn assembly 2 toward the front sound cavity 111 or the rear sound cavity 112 away from the horn assembly 2. For example, if the vertical distance between one end of the pressure equalizing member 3 and the plane of the speaker assembly 2 is smaller than the vertical distance between the opposite end of the pressure equalizing member 3 and the plane of the speaker assembly 2, the pressure equalizing member 3 is deviated from the speaker assembly 2 in the direction from the one end to the other end.

Equalizer 3 deviates horn module 2 gradually on horn module 2 toward the extending direction of the inner wall of casing 1, and then demonstrates equalizer 3 and is preset the angle setting for horn module 2.

Be for loudspeaker subassembly 2 through pressure equalizing part 3 that sets up between the inner wall of casing 1 and loudspeaker subassembly 2 and predetermine the angle setting, make pressure equalizing part 2 deviate loudspeaker subassembly 2 from loudspeaker subassembly 2 to one side of loudspeaker subassembly 2 of the extending direction of the inner wall of casing 1, can reduce the projection of pressure equalizing part 3 on loudspeaker subassembly 2 corresponding plane under the prerequisite of the size of not reducing pressure equalizing part 3, also can reduce the distance between the inner wall of loudspeaker subassembly 2 and casing 1, make the size of whole earphone 100 reduce. For the direct tiling of equalizer 2 to connect between the inner wall of casing 1 and loudspeaker subassembly 2, the equalizer 2 of predetermineeing the angle setting can practice thrift the space effectively with deviating loudspeaker subassembly 2, reduces whole earphone 100's size, and simple structure, easily realizes, for in the front sound chamber 111 set up the hole intercommunication external, can obtain better pressure-equalizing effect, need not anxious people's ear and press close to pressure-equalizing hole 31 and cause pressure-equalizing hole 31 to ventilate unsmoothly.

Specifically, the pressure equalizing member 3 may be sheet-shaped, and both side surfaces of the pressure equalizing member 3 may be each of a planar structure or a curved structure. The included angle between the equalizing piece 3 and the central axis of the horn component 2 is greater than 0 degree and less than or equal to 90 degrees. Optionally, the pressure-equalizing member 3 is at an angle of 10 to 80 degrees with respect to the central axis of the horn assembly 2, and the end points of the above range may include neither or both of these numbers. Optionally, the pressure equalizer 3 is angled 30 to 70 degrees from the central axis of the horn assembly 2. Optionally, the pressure equalizer 3 is angled from 45 to 60 degrees from the central axis of the horn assembly 2.

By setting the pressure equalizing member 3 at the above-mentioned preset angle, the structural strength and the pressure equalizing effect can be effectively balanced, and the size of the entire headphone 100 can be reduced better on this basis.

Referring further to fig. 4, fig. 4 is a schematic view of the pressure equalizer of fig. 3 at a predetermined angle relative to the horn assembly.

Specifically, the pressure equalizing member 3 is offset from the horn assembly 2 toward one side of the horn assembly 2 in the extending direction from the horn assembly 2 to the inner wall of the housing 1, and extends to the inner wall of the housing 1 and abuts against the inner wall of the housing 1.

As shown in fig. 3 and 4, in the extending direction of the pressure equalizing member 3, one side edge of the pressure equalizing member 3 may be fixedly connected to the horn assembly 2, and the other side edge of the pressure equalizing member 3 may abut against the inner wall of the housing 1. In some embodiments, the equalizer 3 may be fixedly connected to a side of the speaker assembly 2 facing the rear sound cavity 112, and extend in a direction away from the speaker assembly 2 toward the rear sound cavity 112. In other embodiments, the equalizing member 3 may be fixedly connected to a side of the speaker assembly 2 facing the front sound cavity 111, and extend in a direction away from the speaker assembly 2 toward the front sound cavity 111.

Specifically, the equalizer 3 may be fixedly connected with the basin frame 21 of the speaker assembly 2. Further, the pressure equalizing member 3 and the tub frame 21 are integrally formed. Thus, the equalizing member 3 and the horn assembly 2 are conveniently mounted as a whole. Of course, the pressure equalizer 3 may be fixedly connected to the inner wall of the housing 1 so as to abut against the horn unit 2.

For example, the speaker assembly 2 has a notch (not shown) at the periphery of the portion connected to the equalizing member 3, and the inner wall of the housing 1 covers the notch to form the gap. The pressure equalizing piece 3 can cover the gap, and the front sound cavity 111 and the rear sound cavity 112 are communicated through the gap and the pressure equalizing hole 31, so that the air pressure of the front sound cavity 111 and the air pressure of the rear sound cavity 112 are balanced conveniently. For example, the gap is left between the position of the horn assembly 2 where the annular platform 14 is connected and the annular platform 14 without sealing or strictly sealing, and the pressure equalizing member 3 can cover the gap, thereby allowing the air to flow between the front sound chamber 111 and the rear sound chamber 112 through the gap and the pressure equalizing hole 31. Other sides of homobaric 3 except being connected with the inner wall of loudspeaker subassembly 2 and casing 1 or the both sides limit of butt and loudspeaker subassembly 2 and casing 1 between the space can be used for sealed glue to carry out the shutoff to make the air current only flow through pressure-equalizing hole 31 after flowing from the clearance, and reduce and reveal, balanced pressure release effect and audio effect.

Alternatively, the housing 1 may be provided with a placing groove 121 on an inner wall thereof. The placement groove 121 may communicate the front sound cavity 111 and the rear sound cavity 112 to form the above-described gap. When the horn assembly 2 is placed in the accommodating chamber 11, a gap is formed between the horn assembly 2 and the placing groove 121. One side of the equalizer 3, which is far away from the horn assembly 2, may extend into the placing groove 121 and abut against the bottom wall of the placing groove 121. The bottom wall of the placing groove 121 may refer to a wall of the placing groove 121 facing into the accommodating chamber 11.

Through setting up standing groove 121 to make loudspeaker subassembly 2 extend to the diapire butt with standing groove 121 in placing 121, so can fix a position pressure-equalizing member 3, and restrict its rotation, and then can improve structural reliability. Moreover, under the unchangeable condition of angle and size of predetermineeing of voltage equalizer 3, set up standing groove 121 and can hold partial voltage equalizer 3, and then can further reduce earphone 100's size for earphone 100's volume is more miniaturized.

Specifically, the placement groove 121 may further penetrate the annular platform 14 to communicate the front sound cavity 111 and the rear sound cavity 112. Further, the placement groove 121 may be opened in a part of the inner wall of the casing 1 forming the rear sound cavity 112, and one end of the placement groove 121 may extend to the annular platform 14 and penetrate through a side surface of the annular platform 14 facing the rear sound cavity 112, and the other end thereof communicates with the rear sound cavity 112. The outer periphery of the horn assembly 2 and the inner wall of the housing 1 form a gap, and the horn assembly 2 and the annular platform 14 form a gap therebetween, such that the front sound cavity 111 and the rear sound cavity 112 communicate. Optionally, the projection shape of the pressure equalizing member 3 on the plane where the annular bearing platform 14 is located is matched with the shape of the inner wall of the placing groove 121, so that the pressure equalizing member 3 can better cover the gap, and a better pressure equalizing effect and an audio effect can be achieved.

The equalizer 3 may be provided with a damping element 4, such as a damping cloth, a damping cotton or a damping paper. The damping element 4 may cover the pressure equalizing hole 31. By providing the damping element 4, acoustic damping can be achieved, and a large acoustic leakage is not caused while maintaining air pressure balance, thereby improving the low frequency of the earphone 100. Alternatively, the damping element 4 may be fixedly attached to a side surface of the equalizer 3 near the front sound cavity 111.

In conclusion, through with equalizer 3 for loudspeaker subassembly 2 preset angle setting, under the prerequisite that does not change equalizer 3 size, can reduce the distance between the inner wall of casing 1 and loudspeaker subassembly 2, and then practiced thrift the space, simple structure easily realizes.

The above description is only an embodiment of the present application, and not intended to limit the scope of the present application, and all modifications of equivalent structures and equivalent processes, which are made by using the contents of the specification and the drawings, or directly or indirectly applied to other related technical fields, are also included in the scope of the present application.
