Referring to fig. 1 to 5, the present embodiment provides a speaker 10 applied to a display device (not shown), where the display device includes a circuit board 20, and the circuit board 20 is used to implement wireless connection between the display device and the internet.

The loudspeaker 10 includes a housing 11 and an actuator 14 disposed within the housing 11, the actuator 14 being any one of an electromagnetic actuator, a magnetostrictive actuator, and a piezoelectric actuator.

In some embodiments, the housing 11 includes a body 111 and a snap member 112, the exciter 14 is located in the body 111, and the shape of the body 111 can be set as desired.

Joint spare 112 protrusion sets up on the outer wall of body 111, and joint spare 112 is a plurality ofly, and a plurality of joint spares 112 are used for setting up along circuit board 20's circumference interval, and like this, circuit board 20 fixes back on speaker 10, and a plurality of joint spares 112 can enclose and establish the circumference at circuit board 20, and it is fixed to form the multiple spot between circuit board 20 and the speaker 10, and circuit board 20's fixed stability is higher.

In some embodiments, one end of the clip 112 is connected to the outer wall of the body 111, and the other end is provided with a stopper 1121 for pressing the circuit board 20 onto the body 111.

Specifically, the distance between the stopping portion 1121 and the body 111 may be smaller than the thickness of the circuit board 20, so that when the circuit board 20 is clamped between the stopping portion 1121 and the body 111, the stopping portion 1121 may be pressed against the circuit board 20 to realize the fastening connection between the circuit board 20 and the speaker 10.

Thus, the circuit board 20 is integrally connected to the speaker 10 without affecting the learning effect of the speaker 10. The backplate of display device can only set up the connecting hole that corresponds with speaker 10, has reduced the piece that generates between circuit board 20 and the backplate and has got into the possibility of display module assembly one side, has improved display device's equipment yields.

Meanwhile, a circuit board support in the prior art is removed, and the die sinking cost is reduced.

The stopping portion 1121 may be an elastic material, and presses the circuit board 20 against the body 111 by its own elastic force. In some optional embodiments, the clip 112 includes a connecting portion 1122 and a stopping portion 1121, the connecting portion 1122 connects the body 111 and the stopping portion 1121 respectively, and an included angle is formed between the extending direction of the stopping portion 1121 and the extending direction of the connecting portion 1122, that is, the clip 112 has a hook-like structure, and the structure is relatively simple.

Specifically, the clip 112 includes a connecting portion 1122 and a stopper portion 1121, two ends of the connecting portion 1122 are respectively connected to the body 111 and the stopper portion 1121, and the connecting portion 1122 is in a rod shape and is a flexible member, and can be bent and deformed under an external force.

Thus, when the circuit board 20 is assembled on the speaker 10, the circuit board 20 can be held and moved toward the side close to the body 111, the circuit board 20 and the clip 112 are pressed against each other, so that the connecting portion 1122 is bent and deformed and avoids the circuit board 20, and the connecting portion 1122 is deformed again until the circuit board 20 contacts the housing 11. At this time, the stopper 1121 is located on a side of the circuit board 20 away from the body 111, and the circuit board 20 is limited between the stopper 1121 and the body 111, that is, the assembly between the circuit board 20 and the speaker 10 is realized, and the operation is convenient.

In some embodiments, a reinforcing rib may be disposed at a connecting position of the connecting portion 1122 and the body 111 to improve the strength of the clip 112.

The clamping member 112 and the body 111 may be of a split structure, and the clamping member 112 is fixed on the body 111 by a threaded fastener or the like.

In some alternative embodiments, the snap member 112 may be integrally formed with the body 111. For among the prior art, circuit board 20 and casing 11 all need the shaping of die sinking alone, and this embodiment sets up through with joint spare 112 and body 111 integrated into one piece, can only carry out the die sinking to casing 11, has reduced mould quantity, has reduced the mould cost.

Simultaneously, for the circuit board support among the prior art, the used consumptive material volume of joint spare 112 in this embodiment is less, has reduced raw and other materials cost.

It can be understood that, when the speaker 10 and the circuit board 20 are assembled, the stopper portion 1121 needs to be retracted from the circuit board 20 by bending deformation of the clip 112.

In some alternative embodiments, for assembly, a recess 1111 is formed on an outer wall surface of the body 111, and at least one clip 112 is connected to a bottom wall surface of the recess 1111. Thus, the length of the part of the clamping piece 112 connected with the bottom wall surface of the concave portion 1111 is increased, the flexibility of the part of the clamping piece 112 is increased, the part of the clamping piece 112 is easy to bend and deform, and the circuit board 20 can be conveniently disassembled and assembled.

The depth of the recess 1111 may be set according to the thickness of the housing 11 and the circuit board 20. And the distribution area of the recess 1111 is smaller than the board area of the circuit board 20, so that the circuit board 20 can be still pressed against the outer wall surface of the body 111.

In some embodiments, when the number of the snap members 112 is three, the number of the snap members 112 connected to the recess 1111 may be two.

In order to prevent the circuit board 20 from increasing the size of the speaker 10, in some alternative embodiments, an avoiding step 1112 is disposed on an outer wall surface of the body 111, and the plurality of clamping members 112 are disposed at the avoiding step 1112 to press the circuit board 20 against the avoiding step 1112, so that neither the circuit board 20 nor the clamping members 112 protrude out of the outer wall surface of the body 111, and the circuit board 20 is prevented from changing the structural size of the speaker 10.

It is understood that when the recess 1111 is provided on the body 111, the recess 1111 is also provided on the escape step 1112.

The recess depth of the avoiding step 1112 may be set according to the thickness of the circuit board 20, and the position, distribution area, and the like of the avoiding step 1112 on the outer wall surface of the body 111 are not limited in the present embodiment.

It can be understood that, when the recess depth of the avoiding step 1112 is smaller than the thickness of the housing 11, the avoiding step 1112 can be set by reducing the thickness of the housing 11, and at this time, the avoiding step 1112 does not affect the arrangement of the internal components of the loudspeaker 10 and does not affect the acoustic effect of the loudspeaker 10.

When the recess depth of the avoiding step 1112 is greater than the thickness of the housing 11, the avoiding step 1112 occupies a part of the inner space of the housing 11, and at this time, the avoiding step 1112 may be disposed at a position where the distance between the internal component of the speaker 10 and the housing 11 is relatively large, so as to avoid interference between the avoiding step 1112 and the internal component of the speaker 10. For example, referring to fig. 5, the exciter 14 is disposed at a first end (right end in fig. 5) of the housing 11, the second end (left end in fig. 5) of the housing 11 is hollow, and the avoidance step 1112 may be disposed at the second end of the housing 11, without the avoidance step 1112 interfering with the speaker 10.

Since the inner space of the housing 11 becomes small, the acoustic effect of the speaker 10 can be improved by an acoustic effect algorithm or the like, and the present embodiment is not limited.

In some alternative embodiments, the outer wall of the body 111 is provided with a protruding positioning protrusion 1113, the circuit board 20 is provided with a positioning hole 21, and the positioning protrusion 1113 is used for being inserted into the positioning hole 21 when the circuit board 20 is fixed on the body 111.

Thus, when the circuit board 20 is assembled to the speaker 10, the positioning of the circuit board 20 can be realized by centering the positioning protrusion 1113 with the positioning hole 21, which is convenient to operate.

The number of the positioning protrusions 1113 may be one or more. Illustratively, in the present embodiment, two positioning protrusions 1113 are disposed on the outer wall surface of the body 111.

The positioning projection 1113 may be a cylindrical projection (not shown). To facilitate assembly of the circuit board 20, the diameter of the positioning hole 21 may be larger than the outer diameter of the cylindrical protrusion.

In some alternative embodiments, the cross-sectional dimension of the positioning protrusion 1113 gradually decreases from the end close to the body 111 to the end far from the body 111, that is, the positioning protrusion 1113 is approximately a conical protrusion.

The cross section of the big end of the positioning protrusion 1113 is larger than the diameter of the positioning hole 21.

In this way, when the circuit board 20 is assembled to the speaker 10, the positioning hole 21 is first aligned with the positioning protrusion 1113, and in the initial process of moving the circuit board 20 toward the main body 111, a gap is formed between the small end of the positioning protrusion 1113 and the positioning hole 21, which is easy to operate.

When the circuit board 20 moves toward the body 111, the cross-sectional dimension of the positioning protrusion 1113 gradually increases, and when the cross-sectional dimension of the positioning protrusion 1113 is equal to the inner diameter of the positioning hole 21, the circuit board 20 and the positioning protrusion 1113 contact and abut against each other, and at this time, the stopper 1121 is buckled on the circuit board 20. That is, the positioning protrusion 1113 can effectively connect the circuit board 20 and the body 111 as a whole, so as to avoid the resonance of the circuit board 20 with respect to the speaker 10 during the vibration sound production process of the speaker 10.

In order to avoid relative shaking between the circuit board 20 and the body 111 during the vibration sound production process of the speaker 10, which may cause the circuit board 20 and the speaker 10 to resonate, in some alternative embodiments, the speaker 10 further includes an elastic member 12, and the elastic member 12 is sandwiched between the body 111 and the circuit board 20. Thus, the circuit board 20 can be pressed against the stopping portion 1121 by the elastic force of the elastic element 12, and the circuit board 20 and the speaker 10 can form a stable whole to prevent the circuit board 20 from resonating.

Wherein the elastic member 12 may be a spring.

In view of the small size between the circuit board 20 and the body 111, in some alternative embodiments, the elastic member 12 may be a sheet-shaped structural member and fills a gap between the circuit board 20 and the body 111.

The thickness of the elastic element 12 may be greater than the gap between the circuit board 20 and the body 111, so that the elastic element 12 is filled between the circuit board 20 and the body 111 and can be in a compressed state, and the circuit board 20 can move toward the side away from the body 111 and abut against the stopping portion 1121 under the elastic force of the elastic element 12. That is, the circuit board 20 and the speaker 10 can be effectively connected as a whole, so as to prevent the circuit board 20 and the speaker 10 from resonating during the vibration and sound production of the speaker 10.

Wherein, the thickness of the elastic element 12 can be 8mm-15 mm. The elastic part 12 can be a foam part, a silica gel part or a rubber part, and is low in cost and easy to obtain.

In some embodiments, the area of the elastic member 12 may be larger than the area of the circuit board 20, so that different positions of the circuit board 20 can be supported on the elastic member 12.

In some embodiments, the elastic member 12 may be fixed to the body 111 by an adhesive member, so as to prevent the elastic member 12 from being displaced during the vibration sound production of the speaker 10.

The present embodiment provides a display device (not shown) including a back plate, a circuit board 20, and the above-described speaker 10, the circuit board 20 being fixed to the speaker 10, and the speaker 10 being fixed to the back plate. The circuit board 20 is used to implement wireless communication, and the structure, function, and working principle of the speaker 10 have been described in the above embodiments, which are not described again in this embodiment.

The display equipment can be an industrial personal computer, a self-service inquiry machine, a cash dispenser, a song ordering machine, a self-service retail machine, an electronic whiteboard and the like.

The number of the speakers 10 may be plural according to the channel setting requirement of the display device, and the plural speakers 10 are arranged at different positions of the display device at intervals.

By using the speaker 10 described above, the circuit board 20 is not connected to the back plate, but fixed to the speaker 10, and the back plate may be provided with only the connection holes corresponding to the speaker 10. Therefore, in the assembling process of the display equipment, fragments cannot be generated between the circuit board 20 and the back plate, namely, the generation amount of the fragments is reduced, the influence of the fragments on the image quality of the display equipment is avoided, and the assembling yield of the display equipment is improved.

By fixing the circuit board 20 to the speaker 10, the circuit board 20 and the speaker 10 as a whole can be supplied as a whole on a production line, and the circuit board 20 and the speaker 10 as a whole can simplify the arrangement of parts on the rear side of the rear panel of the display device.

It is understood that the position of the original fixed circuit board 20 in this embodiment may be used to fix other components. For example, in the prior art, different circuit boards 20 may be stacked in the thickness direction of the display device, which makes the display device difficult to repair and the electrical connection wires on the rear side of the backplane difficult to route. When the circuit board 20 is fixed on the speaker 10, the position of the original fixed circuit board 20 can be used to fix other circuit boards 20, so as to avoid stacking a plurality of circuit boards 20. Meanwhile, the electrical connection lines connected to the circuit board 20 and the electrical connection lines connected to the speaker 10 may be arranged side by side to simplify the layout of the electrical connection lines at the rear side of the rear panel of the display device, reducing the maintenance cost.

In some alternative embodiments, the display device further comprises a flexible connector 13, and the speaker 10 is connected to the back plate via the flexible connector 13. Wherein, the flexible connecting piece 13 can be made of rubber, silica gel and the like. Like this, the in-process of speaker 10 equipment to the backplate, flexible connectors 13 links to each other with the backplate, because flexible connectors 13 can take place to warp, can avoid it to generate the piece, effectively prevents that speaker 10 from producing the piece in the equipment process, improves the yields of display device equipment.
