The specific structure of the speaker module provided by the present invention will be described in the following embodiments:

as shown in fig. 1 to 4, in an embodiment of the speaker module 100 of the present invention, the speaker module 100 includes a housing 10, a speaker unit 30, and a ventilation spacer 50, wherein the housing 10 has an inner cavity; the loudspeaker single body 30 is arranged in the inner cavity and forms a rear sound cavity 10b with the enclosure 10 in an enclosing way, and a leakage hole 30a is arranged on the loudspeaker single body 30; the air-permeable isolating piece 50 is arranged in the rear sound cavity 10b and covers the leakage hole 30a, sound-absorbing particles are filled in the rear sound cavity 10b, and the air-permeable isolating piece 50 is used for isolating the sound-absorbing particles from entering the leakage hole 30 a; the material of the air-permeable partition 50 is a porous metal material.

In this embodiment, the housing 10 includes a first housing 11 and a second housing 13 that cover each other, the first housing 11 and the second housing 13 together enclose an inner cavity of the housing 10, and the inner cavity of the housing 10 is used for accommodating internal components of the speaker module 100, such as the speaker unit 30, the air-permeable partition 50, the flexible circuit board 70, and the sound-absorbing particles. It should be noted that, in the practical application process, the first housing 11 and the second housing 13 may be metal members at the same time, and are combined together by laser welding; or can be a plastic piece at the same time, and the plastic piece are combined together in an ultrasonic welding mode; one metal piece and the other plastic piece can be combined together in an adhesive mode. Moreover, the periphery of the joint position of the first casing 11 and the second casing 13 may further enclose a sealing member, and the sealing member is hermetically connected to the first casing 11 and the second casing 13, so as to improve the sealing performance of the enclosure 10, and provide a more independent and safer working environment for the internal components of the speaker module 100.

The speaker unit 30 is assembled in the first housing 11, specifically: the first housing 11 includes a bottom wall 111 and a side wall 113 protruding from one side surface of the bottom wall 111, the side wall 113 is disposed around a periphery of the bottom wall 111, and an end of the side wall 113 facing away from the bottom wall 111 is combined with the second housing 13, so that the first housing 11 and the second housing 13 are fixedly connected. The first housing 11 further includes a frame 115, the frame 115 is disposed on the surface of the bottom wall 111 where the side wall 113 is disposed, and is located inside the side wall 113; the frame 115 surrounds the speaker unit 30 in the circumferential direction of the front portion of the speaker unit 30. That is, the frame body 115 is disposed around, the shape of the space inside the frame body 115 is adapted to the shape of the front part of the speaker unit 30, and the front part of the speaker unit 30 is inserted into the frame body 115 to close the space inside the frame body 115 to form the front sound cavity 10 a; at this time, the remaining portion of the inner cavity of the housing 10 forms a rear acoustic cavity 10 b.

The ventilation spacer 50 is fitted in the first housing 11 and has dual functions of a spacer function and a ventilation function. The insulating function of the breathable partition 50 means that the breathable partition 50 will divide the rear acoustic chamber 10b into a filling chamber and an insulating chamber. The filling cavity is used for filling sound-absorbing particles, and the isolation cavity is used for isolating the leakage holes 30a which are communicated with the rear sound cavity 10b on the loudspeaker single body 30 from the sound-absorbing particles, so that the sound-absorbing particles cannot enter the sound-absorbing particles. The ventilation function of the air-permeable partition 50 means that although sound-absorbing particles cannot pass through the air-permeable partition 50, the airflow can pass through the air-permeable partition 50 and react with the sound-absorbing particles.

It is understood that in the rear acoustic cavity 10b of the speaker module 100, the back of the speaker unit 30 generally does not have a regular planar shape (as shown in fig. 5, the back of the speaker unit 30 has a recess at four corners thereof, and the defect location can be used as the leakage hole 30 a. of course, the location of the leakage hole 30a can also be located on the side of the back of the speaker unit 30, in this case, the recess at four corners of the back of the speaker unit 30 is simply an avoidance space, as shown in fig. 7), so that the physical volume of the rear acoustic cavity 10b can be increased. However, the mode that the sound particles were kept apart to the screen cloth subassembly that has now, hardly turn into the filling volume of inhaling the sound particles with this part physical volume that increases to cause the space extravagant, performance promotion not enough. The fundamental reason is that the existing mesh assembly generally comprises a support ring and mesh, and the mesh needs to be mounted and fixed in the rear acoustic cavity 10b by means of the support function of the support ring; however, the support ring is generally a narrow ring-shaped structure, and on the premise of ensuring the stability of the mesh cloth fixed to the support ring and the convenience of the mesh cloth being assembled on the support ring and the support ring being fixed in the rear acoustic cavity 10b, the support ring is difficult to adopt a special-shaped structure, which results in failure to adapt the back of the speaker unit 30 well.

In view of such a disadvantage, the present embodiment adopts the air-permeable isolating member 50 made of porous metal material to isolate the sound-absorbing particles. At this time, since the breathable partition 50 is made of a porous metal material, the breathable partition 50 has an integral structure and high strength, and can well meet the stability requirement when the breathable partition 50 is fixed and the convenience requirement in assembly. Simultaneously, because ventilative separator 50 is structure as an organic whole, intensity is higher, can also obtain when manufacturing with the better shape of speaker monomer 30 back adaptation to the increase that will be brought by speaker monomer 30's back sound chamber 10b physical volume is irregular turns into the increase of filling chamber physical volume, realizes inhaling the increase of sound granule filling volume, and then makes speaker module 100's acoustic performance promote. On the other hand, since the porous metal material has the characteristics of sound absorption and heat conduction, the equivalent volume of the rear sound cavity 10b can be further increased, the acoustic performance of the speaker module 100 can be improved, and the heat dissipation performance of the speaker module 100 can be improved.

It should be noted that the porous metal material is a metal material with a large number of directional or random holes dispersed therein and a hole diameter of about 2um to 3 mm. Due to the different design requirements of the pores, the porous metal material can take various forms, such as foam type, lotus root type, honeycomb type, etc. In an embodiment of the present invention of the speaker module 100, the porous metal material is one of a foam type porous metal material, a lotus-shaped porous metal material, and a honeycomb type porous metal material. Wherein, the foam type porous metal material can be selected from foam nickel or foam copper.

In addition, the porous metal material can be divided into an independent pore type and a continuous pore type according to the pore form: the independent hole type has the characteristics of small specific gravity, good rigidity, good specific strength, good vibration absorption and sound absorption performance and the like; the continuous hole type has the characteristics of good permeability, good air permeability and the like in addition to the characteristics of the independent hole type.

Note that, the back of the speaker unit 30 is opposite to the front of the speaker unit 30, and they are disposed facing the front and the back of the speaker unit 30. Generally, a diaphragm is disposed at the front of the speaker unit 30 for radiating sound waves to the front of the speaker unit 30; the back of the speaker unit 30 is provided with a leak hole 30a for balancing air pressure inside the speaker unit 30. Further, it is understood that the back of the speaker unit 30 has an end surface facing the rear of the speaker unit 30, i.e., the back surface 31 of the speaker unit 30; the back of the speaker unit 30 also has sides facing the sides of the speaker unit 30, and four sides in this embodiment are disposed around the back of the speaker unit 30.

In addition, understandably, the shell is also provided with filling holes, and sound-absorbing particles are filled through the filling holes, so that the maximum filling can be realized. Moreover, the speaker module 100 may further include a flexible circuit board 70, one end of the flexible circuit board 70 may be electrically connected to the speaker unit 30 by soldering, and the other end of the flexible circuit board 70 may be exposed to the outer surface of the housing 10 for electrically connecting to other devices or modules.

As shown in fig. 1 to 3, in an embodiment of the speaker module 100 of the present invention, the air-permeable partition 50 is disposed on the back of the speaker unit 30. Therefore, the installation and fixation of the breathable partition piece 50 can be realized, the back of the loudspeaker single body 30 is fully utilized as a support, the structure is simple, the assembly is rapid, and the stability and the reliability are excellent. On the other hand, the ventilation spacer 50 covers the back of the speaker unit 30, and can also protect the speaker unit 30. Specifically, the fixing mode between the breathable isolation piece 50 and the speaker unit 30 can be gluing, welding, buckling limiting, interference fit and the like, and the technical personnel in the field can carry out reasonable design according to practical application scenes, and the design is not repeated one by one.

In this embodiment, the speaker unit 30 includes a magnetic circuit system and a frame 31; wherein the magnetic circuit system comprises a magnetic yoke 33; the frame 31 has a ring-shaped body, the ring-shaped body and/or the magnetic conductive yoke 33 has a positioning protrusion 331 at the periphery, the positioning protrusion 331 is connected to the other periphery, the ring-shaped body has a bottom surface facing the magnetic conductive yoke 33, and a leakage hole 30a is formed between the magnetic conductive yoke 33 and the bottom surface. At this time, the air-permeable spacer 50 is provided to cover the magnetic yoke 33, and covers the leak hole 30a formed by the tub 31 and the magnetic yoke 33.

The position of the leakage hole 30a may be located at four corners of the back surface 31 of the speaker unit 30 (as shown in fig. 5), or may be located on the side surface of the back of the speaker unit 30 (as shown in fig. 7).

As shown in fig. 6, in an embodiment of the speaker module 100 of the present invention, the air-permeable partition 50 includes a cover plate 51 and a side plate 53 extending from the periphery of the cover plate 51, the cover plate 51 covers the back surface 31 of the speaker unit 30, and the side plate 53 is disposed around the speaker unit 30. Thus, the ventilation spacer 50 can be more closely matched with the back of the speaker unit 30, so as to improve the installation stability of the ventilation spacer 50 and the protection effect on the speaker unit 30.

As shown in fig. 5 and 6, in an embodiment of the speaker module 100 of the present invention, a concave edge 531 is formed at a position of the side plate 53 corresponding to the leakage hole 30a, and the concave edge 531 is formed by the side plate 53 being recessed toward the leakage hole 30 a.

In this embodiment, the positions of the leakage holes 30a are located at four corners of the back surface 31 of the speaker unit 30. At this time, the irregularity of the back of the speaker unit 30 is caused by the leakage holes 30a formed at the four corners of the back of the speaker unit 30. The physical volume of the rear acoustic chamber 10b is increased by the space made available by these leakage holes 30 a. In order to convert the increased physical volume into the filling volume of the sound-absorbing particles, the side plate 53 is configured into two parts, one part is covered on the side surface of the back of the speaker unit 30, and the other part is the concave edge 531 inserted in the leakage hole 30 a. That is, the technical scheme of this embodiment configures the side plate 53 into the form that the outer profile of the back of the speaker unit 30 is more adapted, so as to convert the increase of the physical volume of the rear sound cavity 10b caused by the irregular back of the speaker unit 30 into the increase of the physical volume of the filling cavity, thereby realizing the increase of the filling volume of the sound-absorbing particles, and further improving the acoustic performance of the speaker module 100.

As shown in fig. 7 and 8, in an embodiment of the speaker module 100 of the present invention, a gap is formed at least one corner of the magnetic yoke 33, and an avoiding space 30b is formed at a position of the frame 31 corresponding to the gap;

the side plate 53 is formed with a concave side 531 at a position corresponding to the avoidance space 30b, and the concave side 531 is formed by the side plate 53 being recessed toward the avoidance space 30 b.

In this embodiment, the position of the leak hole 30a is located on the side of the back of the speaker unit 30. Specifically, the back of the speaker unit 30 has two sides facing away from each other, and a leak hole 30a is formed in each side. At this time, the irregularities of the back of the speaker unit 30 are caused by the escape spaces 30b formed at the four corners of the back of the speaker unit 30. The space made by these escape spaces 30b increases the physical volume of the rear acoustic chamber 10 b. In order to convert the increased physical volume into the filling volume of the sound-absorbing particles, the side plate 53 is configured into two parts, one part is covered on the side surface of the back of the speaker unit 30, and the other part is the concave edge 531 inserted into the avoiding space 30 b. That is, the technical scheme of this embodiment configures the side plate 53 into the form that the outer profile of the back of the speaker unit 30 is more adapted, so as to convert the increase of the physical volume of the rear sound cavity 10b caused by the irregular back of the speaker unit 30 into the increase of the physical volume of the filling cavity, thereby realizing the increase of the filling volume of the sound-absorbing particles, and further improving the acoustic performance of the speaker module 100.

In addition, in the technical solution of this embodiment, in order to further save the material of the air-permeable partition 50 and avoid the waste of resources, the number of the air-permeable partitions 50 is also configured to be two, and each air-permeable partition 50 covers one leakage hole 30 a. At this time, each of the air-permeable partitions 50 includes two concave edges 531, and the two concave edges 531 are recessed corresponding to the two escape spaces 30b, respectively. It can be understood that, compared with the configuration mode that the ventilation isolation member 50 is covered by a whole block, the ventilation isolation member 50 is configured in a plurality of and separated ways, which is more beneficial to saving materials.

The air-permeable partition 50 may be attached and fixed by bonding the cover plate 51 to the magnetic yoke 33 (specifically, the back surface of the magnetic yoke 33), by bonding the side plate 53 to the peripheral side of the speaker unit 30 (specifically, the side surface of the frame 31 and/or the side surface of the magnetic yoke 33), or by combining both of them. Of course, in addition to the bonding manner, the bonding manner may be replaced or assisted by a snap connection manner or the like.

As shown in fig. 5 and 6, in an embodiment of the speaker module 100 of the present invention, the magnetic yoke 33 has two side edges disposed back to back, and a positioning protrusion 331 is convexly disposed on one side of the side edge facing the frame 31;

the side plate 53 is formed with a positioning notch 533 at a position corresponding to the positioning protrusion 331, and each positioning protrusion 331 is inserted into one positioning notch 533.

Thus, the fitting between the side plate 53 and the back of the speaker unit 30 is tighter, so that the position of the side plate 53 is more strongly defined, and the mounting stability of the air-permeable partition 50 is improved. Meanwhile, the sealing performance of the filling cavity to the sound absorption particles is improved, and the risk that the sound absorption particles go to one side of the loudspeaker unit 30 is reduced, so that the probability that the acoustic performance of the loudspeaker module 100 is affected is reduced, and the reliability of the loudspeaker module 100 is improved.

As shown in fig. 1 to 4, in an embodiment of the speaker module 100 of the present invention, an inner cavity wall of the housing 10 has a mounting surface 1111, the mounting surface 1111 is convexly provided with a frame 115, and the speaker unit 30 is disposed in the frame 115 for closing a space inside the frame 115 to form a front acoustic cavity 10 a;

one end of the side plate 53 facing away from the cover plate 51 is at least partially disposed opposite to and hermetically connected with one end of the frame 115 facing away from the mounting surface 1111.

In this embodiment, the mounting surface 1111 is an inner surface of the bottom wall 111 of the first housing 11. Therefore, the arrangement of the frame body 115 on the mounting surface 1111 in this embodiment is substantially the same as the arrangement of the frame body 115 on the surface of the bottom wall 111 provided with the side wall 113 in the first embodiment, and thus, the description thereof is omitted.

It can be understood that, by hermetically connecting the end of the side plate 53 away from the cover plate 51 with the end of the frame 115 away from the mounting surface 1111, not only the position of the side plate 53 can be further limited, but also the mounting stability of the air-permeable partition 50 can be improved; but also can promote the filling chamber to inhaling the closure of sound granule, reduce and inhale the risk that the sound granule goes to speaker monomer 30 one side, reduce the probability that speaker module 100 acoustic performance receives the influence, promote speaker module 100's reliability.

In the practical application process, the sealing connection between the end of the side plate 53 away from the cover plate 51 and the end of the frame body 115 away from the mounting surface 1111 may be realized by, for example, abutting the end of the side plate 53 away from the cover plate 51 against the end of the frame body 115 away from the mounting surface 1111, and disposing a silicone member or a rubber member between the end of the side plate 53 away from the cover plate 51 and the end of the frame body 115 away from the mounting surface 1111.

As shown in fig. 3, in an embodiment of the speaker module 100 of the present invention, the gap between the side plate 53 and the frame 115 is sealed by glue (not shown).

It can be understood that before the glue is solidified, the glue can better fill the gap between the side plate 53 and the frame 115 due to the changeable shape, so that the cross-sectional shape of the glue can be better adapted to the gap when the glue is solidified to form a sealing member, thereby further improving the limiting effect on the position of the side plate 53 and the sealing performance of the filling cavity on the sound-absorbing particles. On the other hand, since the glue has a certain fluidity, the gap between the sealing side plate 53 and the frame 115 can be sealed to a certain extent while the gap between the speaker unit 30 and the frame 115 is sealed, so that the sealing performance of the rear acoustic cavity 10b is improved, and the acoustic performance of the speaker module 100 is improved.

In the practical application process, the glue can be epoxy glue, white latex, ultraviolet curing glue and the like.
