The sounding main body comprises a vibrating diaphragm, and further comprises an outer frame, a voice coil, a Printed Circuit Board (PCB) and other structures.

In the embodiment of the present disclosure, the housing 10 has a columnar structure, and the first opening 101 is disposed at one end of the columnar structure. The surface of the partition 13 is parallel to the axis of the housing 10, and the first cavity 102 and the second cavity 103 are arranged side by side along the lateral direction of the housing 10, which is a direction perpendicular to the direction in which the axis extends. Accordingly, the first and second sounding

bodies

11 and 12 are also arranged side by side.

As shown in fig. 1, a casing 10 provided in the embodiment of the present disclosure is a prism structure, and the prism structure is formed by connecting two rectangular parallelepiped casings, wherein two rectangular parallelepiped cavities are respectively used for arranging a first sound generating body 11 and a second sound generating body 12, and a partition 13 is located at a junction of the two rectangular parallelepiped casings.

In other embodiments, the housing 10 may also be a cylindrical structure, a circular truncated cone structure, a prismatic truncated cone structure, or other three-dimensional structures.

In the disclosed embodiment, the housing 10 and the partition 13 are formed as an integral structure or an assembled structure, which is convenient for manufacturing.

Fig. 2 is a schematic structural diagram of a speaker module according to an embodiment of the disclosure, and the structure shown in fig. 2 is a structure of the speaker module in fig. 1 after a cut-away portion is formed, so as to better show an internal structure of the speaker module. Fig. 3 is a front view of the speaker module shown in fig. 2, i.e., a schematic cross-sectional view of the speaker module.

As shown in fig. 2 and 3, both ends of the housing 10 are open, that is, the housing 10 has a second opening 104 in addition to the first opening 101, and the second opening 104 is opposite to the first opening 101.

As shown in fig. 2 and 3, the cavity 100 in the housing 10 includes portions located respectively in front and rear of the two sound emission bodies in the axial direction of the housing 10, a front cavity 1001 and a rear cavity 1002 as speaker modules, the front cavity 1001 being adjacent to the first opening 101, and the rear cavity 1002 being adjacent to the second opening 104. The vibrating diaphragm in the sound production main part can drive the air vibration in front chamber and/or the back chamber through self vibration, and then realizes the sound production.

As shown in fig. 3, a distance D1 between a side surface of the first opening 101 of the partition plate 13 and an end surface of the housing 10 around the first opening 101 is greater than 0, that is, a side surface of the partition plate 13 close to the first opening 101 is recessed into the cavity relative to the end surface of the housing 10 around the first opening 101, so that the front cavity of the first sound generating body 11 and the front cavity of the second sound generating body are communicated, thereby the front cavities of the two sound generating bodies are shared, and on the premise that the size of the front cavity 1001 can be ensured, the size of the housing is appropriately reduced, thereby being beneficial to the miniaturization of the speaker module.

As shown in fig. 3, the distance D2 between the side surface of the partition plate 13 close to the second opening 104 and the end surface of the housing 10 around the second opening 104 is greater than 0, that is, the side surface of the partition plate 13 close to the second opening 104 is recessed toward the cavity with respect to the end surface of the housing 10 around the second opening 104, so that the rear cavity of the first sound generating body 11 and the rear cavity of the second sound generating body are communicated, thereby making the rear cavities of the two sound generating bodies common.

As shown in fig. 3, the rear cavity 1002 is shared by the first sound generating body 11 and the second sound generating body 12, and the rear cavity is larger in size due to the fact that the two sound generating bodies share the rear cavity, so that the range from the resonance frequency F0 of the first sound generating body 11 to the cut-off frequency in the speaker module is larger, and the range from the resonance frequency F0 of the second sound generating body 12 to the cut-off frequency is larger, thereby increasing the frequency response bandwidth of the speaker module and covering high-frequency to low-frequency output. In addition, since the first sound generating body 11 and the second sound generating body 12 share the rear cavity 1002, the size of the housing can be appropriately reduced on the premise of ensuring the size of the rear cavity 1002, thereby being beneficial to the miniaturization of the speaker module.

Fig. 4 is a schematic structural diagram of another speaker module according to an embodiment of the present disclosure. In contrast to fig. 2, the housing 10 shown in fig. 4 also has a cover plate 105. Fig. 5 is a front view of the speaker module shown in fig. 4, i.e., a schematic cross-sectional view of the speaker module. Referring to fig. 4 and 5, the cover plate 105 is located in the second cavity 103 and on a side of the second sounding body 12 away from the second sounding surface 120, and is connected to the casing 10 and the partition 13.

In this implementation, the thickness of the cover plate 105 is equal to the distance D2 in fig. 3, and the cover plate 105 covers the side of the second sounding main body 12 away from the first sounding surface 110, so that the rear cavity corresponding to the second sounding main body 12 is removed, that is, the second sounding main body 12 has no rear cavity, so that the resonant frequency F0 of the second sounding main body 12 becomes small, and the second sounding main body 12 realizes high-frequency output.

Optionally, the cover plate 105 and the housing 10 are of an integrally formed structure or assembled.

As shown in fig. 1 to 4, in one possible implementation, the volumes of the first sound generating body 11 and the second sound generating body 12 are not equal, for example, as shown in the figure, the volume of the first sound generating body 11 is larger than the volume of the second sound generating body 12.

Here, the volumes of the first and second sounding

bodies

11 and 12 are not equal, and may be generally achieved by at least one of the length, width, and height being different.

As shown in fig. 4, the volume of the first sounding body 11 is larger than that of the second sounding body 12, that is, a sounding body with a smaller volume is provided with the cover plate 105 in fig. 4, or a sounding body with a smaller volume is provided without a rear cavity.

When two sound production main parts are designed to be large and small, the small sound production main part is used for high-frequency output, and the large sound production main part is used for low-frequency output.

In other possible implementations, the volumes of the first and second

sound emitting bodies

11 and 12 may be equal.

Fig. 6 is a schematic cross-sectional view of another speaker module according to an embodiment of the present disclosure. Compared with fig. 3, the housing 10 of the speaker module further has a skirt 106, the skirt 106 is located on the inner wall of the housing 10 and is close to the first opening 101, and the skirt 106 is connected to the first sound generating body 11 and the second sound generating body 12 respectively.

In the actual manufacturing process, the sounding main body is welded with the shell and the partition plate, the welding mode can be spot welding, gaps exist among welding spots, and sealing is achieved through dispensing.

In one implementation of the present disclosure, the casing 10 is a metal casing, the partition 13 is a metal partition, and the metal casing and the metal partition are respectively welded to the first sound generating body 11 and the second sound generating body 12. In the related art, the plastic housing is usually more than 1mm due to the limitation of the injection molding process, and the metal housing has a smaller thickness compared to the injection molded housing, so that the size of the whole speaker module is smaller, for example, the wall thickness of the housing 10 ranges from 0.2mm to 0.4mm, and the wall thickness of the partition 13 ranges from 0.2mm to 0.4mm. Meanwhile, the connection mode is realized by adopting a spot welding and dispensing mode, and compared with the prior art in which glue is directly adopted for connection, the thickness is smaller.

Illustratively, the housing 10 is a steel housing, and the partition 13 is a steel partition.

Referring to fig. 9 and 10, the housing 10 includes a lower housing 107 and an upper housing 108, the upper housing 108 is butted with the lower housing 107, and a trace through hole 109 is formed at the joint of the upper housing 108 and the lower housing 107.

The middle of the FPC trace 16 is located in the trace through hole 109, one end of the FPC trace 16 is connected to the first sound generating main body 11 and the second sound generating main body 12, and the other end of the FPC trace 16 is located outside the housing 10.

Illustratively, one end of the FPC trace 16 connects the PCBs of the first and second

sound emitting bodies

11 and 12.

Illustratively, the other end of the FPC trace 16 is used to connect to the motherboard of the terminal device.

For example, the end of the FPC trace 16 outside the housing has a plug terminal, through which the electrical connection between the FPC trace and the motherboard can be conveniently achieved.

The FPC wiring is arranged to connect the first sounding main body 11 and the second sounding main body 12, so that the first sounding main body 11 and the second sounding main body 12 can be connected with a main board, and audio output is achieved by receiving audio signals.

As shown in fig. 9 and 10, the FPC trace 16 is embedded in the trace through hole 109, which is a strip-shaped through hole, and the FPC trace is disposed in the strip-shaped through hole, so that the FPC trace 16 can extend from a position close to the first sound emitting body 11 to a position close to the second sound emitting body 12, thereby enabling the FPC trace 16 to be electrically connected to the two sound emitting bodies at the same time.

As shown in fig. 9, the distance of the circumference of the outer wall of the housing 10 that is bypassed by the FPC traces 16 is less than 1/2 of the total length of the circumference of the outer wall of the housing 10.

In the embodiment of the present disclosure, at the position having the trace through hole 109, the upper casing 108 and the lower casing 107 are hermetically connected by glue (for example, by dispensing), and at other positions except the position having the trace through hole 109, the upper casing 108 and the lower casing 107 are welded and sealed by glue, for example, spot welding is adopted for welding, and the gap between the welding points is sealed by dispensing. The lower shell and the upper shell are connected in a sealing mode through glue at the position with the wiring through hole, and the lower shell and the upper shell are welded and sealed through glue at the other positions except the position with the wiring through hole, so that a sealing structure is formed at the position of the FPC wiring.
