It is understood that the fourth housing 400 may be first mounted to the third housing 300 and then the circuit board 500 may be mounted.

As shown in fig. 3 and 4, in one embodiment, the battery 600 and the speaker 700 are arranged in a first direction, i.e., a Y direction, within the first receiving space 40. The battery 600 includes a first end 610 and a second end 620, and the speaker 700 includes a third end 710 and a fourth end 720. It is understood that the first end 610 and the second end 620 are of unitary construction and the third end 710 and the fourth end 720 are of unitary construction. The first end 610 faces away from the side of the main body 20 where the sound outlet 110 is disposed, and the second end 620 faces toward the side of the main body 20 where the sound outlet 110 is disposed, that is, the first end 610 faces toward the second side 22, and the second end 620 faces toward the first side 21. The third end 710 faces away from the sound outlet 110, and the fourth end 720 faces the sound outlet 110, i.e. the third end 710 faces the second side 22 and the fourth end 720 faces the first side 21. The first end 610 is attached to or has a gap with the circuit board 500.

As shown in fig. 3 and 4, in an embodiment, the outer surface of the first end 610 is a cylindrical structure, and the second end 620 is a circular truncated cone-shaped structure or a similar circular truncated cone-shaped structure, and the end with the larger diameter of the circular truncated cone-shaped structure is connected with the cylindrical structure. It is understood that cylinder-like structures and truncated cone-like structures are also within the scope of the present application. The third end 710 and the fourth end 720 are both cylindrical structures. In the XY plane, the projected size of the first end 610 is larger than the projected size of the second end 620, i.e., the diameter of the first end 610 is larger than the diameter of the second end 620. It will be appreciated that the second end 620 is a truncated cone-like structure, and the diameter of the second end 620 is smaller as the second end 620 is farther away from the first end 610, and the diameter of the second end 620 is equal to the diameter of the first end 610 where the second end 620 joins the first end 610. In the XY plane, the projected size of the third end 710 is smaller than that of the fourth end 720, i.e. the diameter of the third end 710 is smaller than that of the fourth end 720, so that the speaker 700 has a T-shaped structure.

As shown in fig. 9, in one embodiment, in the first direction, Y-direction, the battery 600 and the speaker 700 are arranged side by side, the first end 610 and the third end 710 are located on the same side, and the second end 620 and the fourth end 720 are located on the same side. The third end 710 provides a space for the first end 610 to escape, and the second end 620 provides a space for the fourth end 720 to escape, so that the first accommodating space 40 is fully used in the Y direction, thereby reducing the size of the main body 20 in the Y direction.

In one embodiment, the battery 600 is a pouch battery, that is, the pouch battery is structurally packaged by an aluminum plastic film, and in case of a safety hazard, the pouch battery is blown and cracked at most, and no other damage is caused. Due to the manufacturing process of the round pouch battery, the battery 600 is not generally made in a uniform cylindrical shape. In order to make the most of the space, the present application makes the speaker 700 in a T-shaped structure to be fitted with the battery 600, so as to make the most of the space and reduce the size of the main body 20 in the first direction, i.e., the Y direction.

It is understood that the dimension of the main body 20 in the length direction, i.e., the Y direction, is mainly composed of the wall thickness of the first casing 100 or the second casing 200, the diameter of the battery 600, the diameter of the speaker 700, and the gap between the components. Since the wall thickness of the first casing 100 or the second casing 200 is a fixed parameter due to the casing strength, the injection molding conditions, and the like, the diameters of the battery 600 and the speaker 700 are fixed values, and the assembling clearance is also fixed due to the assembling and the like while the service life and the sound quality are ensured, the size of the main body 20 in the length direction, i.e., the Y direction, is reduced by matching the shape of the speaker 700 with the shape of the battery 600.

As shown in fig. 3, 10 and 11, in one embodiment, the speaker 700 is obliquely offset with respect to the battery 600 so as to more closely conform to the shape of the first receiving space 40, and such that the third end 710 is close to the battery 600 and the fourth end 720 protrudes from the second end 620 in the third direction, i.e., the Z direction. The speaker 700 is deviated from the first direction, i.e., the Y direction, so that the speaker 700 is disposed obliquely in the first receiving chamber. As shown in fig. 3, by obliquely disposing the speaker 700 after the battery 600 is fixed, since the third end 710 has a smaller diameter, the speaker 700 can be brought closer to the battery 600 side even further, so that the space occupied by the speaker 700 in the first direction, i.e., the Y direction, is reduced, the space of the main body 20 in the Y direction is saved, and the size of the main body 20 in the Y direction can be reduced. And the speaker 700 covers the end of the sound outlet cavity 111 facing the first accommodating space 40 after being tilted, so that the sound emitted by the speaker 700 can be directly transmitted out through the sound outlet cavity 111, that is, the sound outlet direction of the speaker 700 is consistent with the direction of the sound outlet nozzle 110, and the sound quality experience of the earphone 10 is improved.

As shown in fig. 3, in one embodiment, the sound outlet tip 110 has a central axis 112, and it will be appreciated that the central axis 112 is located at the center of the sound outlet cavity 111. On a plane perpendicular to the central axis, the projected size of the third end 710 is smaller than that of the fourth end, i.e. the diameter of the third end is smaller than that of the fourth end. In another embodiment, the centerline of the speaker 700 is parallel to the central axis 112, i.e., the central axis 112 is perpendicular to the third end 710 and the fourth end 720. In yet another embodiment, the center line of the speaker 700 coincides with the center axis 112, and it can be understood that the center axis 112 extends through the center of the speaker 700, i.e. the speaker 700 faces the sound-emitting cavity 111, so that the earphone 10 has better sound quality.

After the speaker 700 is disposed to be inclined with respect to the battery 600, depending on the shape and size of the battery 600 and the speaker 700, and the inclination of the speaker 700 with respect to the battery 600, there is an overlap between the projection of the battery 600 on the XY plane and the projection of the speaker 700 on the XY plane, thereby further reducing the size of the main body 20 in the longitudinal direction, i.e., the Y direction. It is understood that, even if the projection of the battery 600 on the XY plane and the projection of the speaker 700 on the XY plane do not coincide with each other after the speaker 700 is tilted with respect to the battery 600, the size of the main body 20 in the longitudinal direction, i.e., the Y direction, can be reduced due to the tilted disposition of the speaker 700.

As shown in fig. 3 and 12, in an embodiment, a positioning groove 120 is formed in the first casing 100 to fix the fourth end 720 of the speaker 700. The groove wall of the positioning groove 120 protrudes from the inner surface of the first casing 100. The sound outlet cavity 111 penetrates through the bottom of the positioning groove 120, so that the sound outlet cavity 111 is communicated with the first accommodating space 40, and the sound emitted by the loudspeaker 700 can be transmitted out of the earphone 10 through the sound outlet cavity 111. The sound outlet cavity 111 is located in the area surrounded by the positioning groove 120, so that the sound outlet direction of the loudspeaker 700 is consistent with the direction of the sound outlet nozzle 110, and the sound quality experience of a user is improved.

In an embodiment, the special-shaped battery 600 and the speaker 700 can be customized according to the shapes of the main body 20 of the earphones 10 with different shapes, and the shape characteristics of the speaker 700 and the battery 600 are fully utilized to minimize the shape size of the main body 20, so as to reduce the oppressive feeling when the user uses the earphones 10 and improve the expression of the product.

The earphone 10 of the present application, under the prerequisite of guaranteeing the live time that battery 600 capacity and tone quality that loudspeaker diameter, through adopting appearance and battery 600 matched with speaker 700 for battery 600 and speaker 700 make full use of space in the length direction of main part 20 is Y direction, in order to reduce the length direction of main part 20 and be the size of Y direction. Through inclining and dislocating the loudspeaker 700 relative to the battery 600, the size of the main body 20 in the length direction, namely the Y direction, is further reduced, the man-machine wearing experience is improved, and the length size of the main body 20 of the manufactured earphone 10 is smaller than that of the similar stacking mode in the market, and the earphone has higher product competitiveness. After the speaker 700 is tilted and dislocated relative to the battery 600, the sound emitting direction of the speaker 700 is consistent with the direction of the sound emitting nozzle 110, so that the sound quality experience of a user is improved. The earphone 10 of the present application does not add any cost compared to the conventional stacked earphone 10, and also facilitates the speaker 700 to better perform its sound quality performance.
