Description

Technical Field

[0001] This utility model relates to the field of loudspeaker technology, specifically to a vibration damping mounting structure for a loudspeaker. Background Technology

[0002] Typically, loudspeaker products consist of two main parts: the speaker body and the housing. The speaker body needs to be installed inside the housing. Currently, when assembling loudspeakers, the speaker body is commonly fixed by applying adhesive, which means using glue to tightly bond the speaker body to the housing. However, this installation method has obvious drawbacks. Since the speaker body will inevitably vibrate when it is working, the vibration will be directly transmitted to the housing without any buffer when it is glued. This can easily cause resonance between the speaker body and the housing, ultimately leading to a significant increase in the vibration amplitude of the entire loudspeaker product, affecting the performance and usability. Utility Model Content

[0003] This invention provides a vibration damping mounting structure for a loudspeaker, which can effectively solve the above-mentioned problems.

[0004] This utility model is implemented as follows:

[0005] A vibration damping mounting structure for a loudspeaker includes a loudspeaker body and a housing.

[0006] The housing has a mounting hole, and a rubber ring is provided inside the mounting hole. The rubber ring includes a connecting part. The outer side of the connecting part contacts the inner side of the mounting hole. The inner side of the connecting part has an abutting part that protrudes inward. The connecting part also has a fixing part near the bottom outer side. The upper end face of the fixing part is fixed to the inner side of the housing with glue.

[0007] The speaker body is placed inside the rubber ring, and the lower end face of the abutting part on the upper end face of the speaker body abuts against it. The side face of the speaker body is bonded to the connecting part with glue.

[0008] As a further improvement, the inner side of the housing is provided with a groove around the mounting hole, and the mounting part is provided with a boss, which is inserted into the groove for engagement.

[0009] As a further improvement, the upper end face of the fixing part is bonded to the housing only on the upper end face and both sides of the boss.

[0010] As a further improvement, the Shore hardness of the rubber ring is 40-60°.

[0011] As a further improvement, the upper end face of the rubber ring is flush with the upper end face of the housing.

[0012] As a further improvement, the mounting hole is square, and the abutting part includes a first abutting part, a second abutting part, a third abutting part and a fourth abutting part that are not connected to each other, respectively provided on the four sides of the square.

[0013] As a further improvement, the bottom of the connecting part and the side near the speaker body is provided with a slope, and glue is filled between the slope and the speaker body.

[0014] The beneficial effects of this utility model are:

[0015] The rubber ring is made of flexible material, and the connection part is not glued to the inner side of the mounting hole. The rubber ring can deform when the speaker vibrates. This deformation can buffer the vibration of the speaker body and reduce the direct transmission of vibration to the shell, thereby effectively reducing the resonance phenomenon between the speaker body and the shell. The connection part of the rubber ring can move, which provides better shock absorption for the speaker body. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.

[0024] In the description of this utility model, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0025] Reference Figure 1-4 As shown, a vibration damping mounting structure for a loudspeaker includes a loudspeaker body 2 and a housing 1. The housing 1 has a mounting hole 11, and a flexible rubber ring 3 is provided inside the mounting hole 11. The rubber ring 3 includes a connecting part 31. The outer side of the connecting part 31 contacts the inner side of the mounting hole 11. No glue is used to adhere and fix the outer side of the connecting part 31 to the inner side of the mounting hole 11. The inner side of the connecting part 31 has an abutting part 32 that protrudes inward. The abutting part 32 can be continuously provided around the inner side of the connecting part 31 or it can be discontinuous, which facilitates the limiting of the loudspeaker body 2 when it is installed. Near the bottom outer side of the connecting part 31, there is also a ring of fixing part 33. The upper end face of the fixing part 33 is fixed to the inner side of the housing 1 by glue.

[0026] The speaker body 2 is inserted into the rubber ring 3 from bottom to top, and the upper edge of the speaker body 2 abuts against the lower end of the abutting part 32. The side of the speaker body 2 is glued to the connecting part 31.

[0027] The vibration of the speaker is mainly along the direction perpendicular to the diaphragm plane. Firstly, since the rubber ring 3 is made of flexible material, it can reduce the resonance between the speaker body 2 and the housing 1. Secondly, the connecting part 31 on the rubber ring 3 is not attached to the inner side of the mounting hole 11. The rubber ring 3 is only attached to the housing 1 by the upper end face of the fixing part 33. The connecting part 31 can move, and the vibration damping effect of the speaker body 2 is better.

[0028] In the embodiment, the structure at the connection between the fixing part 33 and the housing 1 can adopt the following technical solution: the inner side of the housing 1 is provided with a groove 12 around the mounting hole 11, and the mounting part is provided with a boss 34. The boss 34 is inserted into the groove 12 for cooperation. The advantage of adopting the above technical solution is that it increases the contact area between the upper end face of the fixing part 33 and the housing 1, and can better position the rubber ring 3 during installation, as well as improve the connection strength between the rubber ring 3 and the housing 1.

[0029] In the embodiment, when the upper end face of the fixing part 33 is provided with a boss 34, the following technical solution can be adopted when it is bonded to the housing 1: the upper end face of the fixing part 33 is bonded to the housing 1 only on the upper end face and both sides of the boss 34. The advantage of adopting the above technical solution is that while ensuring the bonding strength, the area of ​​lateral bonding is reduced, the bonding point is far away from the connecting part 31, and the shock absorption effect of the rubber ring 3 is better.

[0030] In this embodiment, the Shore hardness of the rubber ring 3 can be selected using the following technical solution: the Shore hardness of the rubber ring 3 is 40-60°. The advantage of using the above technical solution is that this hardness range can provide good shock absorption performance. If the hardness of the rubber ring 3 is higher than 60°, its elastic deformation ability will be relatively poor. When the speaker vibrates, the hard rubber ring 3 cannot effectively absorb and buffer the vibration, which will cause more vibration to be directly transmitted to the housing 1, possibly causing resonance, resulting in distortion of the sound or the generation of additional noise. Conversely, if the hardness of the rubber ring 3 is lower than 40°, although it can absorb vibration well, it may lose its supporting role for the speaker due to excessive deformation. A rubber ring 3 that is too soft may cause the speaker position to shift, affecting the direction of sound propagation and the stability of sound quality.

[0031] In this embodiment, the upper end face structure of the rubber ring 3 can adopt the following technical solution: the upper end face of the rubber ring 3 is flush with the upper end face of the housing 1. The advantage of adopting the above technical solution is that the overall appearance is more aesthetically pleasing.

[0032] In the embodiment, when the mounting hole 11 is square, the abutment portion 32 can adopt the following technical solution, and the abutment portion 32 includes a first abutment portion 321, a second abutment portion 322, a third abutment portion 323 and a fourth abutment portion 324 that are not connected to each other, respectively provided on the four sides of the square. The advantage of adopting the above technical solution is that it can save materials.

[0033] In the embodiment, the adhesive ring 3 and the speaker body 2 can be bonded together using the following technical solution: a slope 35 is provided at the bottom of the connecting part 31 and on the side close to the speaker body 2. Adhesive is filled between the slope 35 and the speaker body 2. The advantage of the above technical solution is that it is easy to fill the adhesive, increase the contact area between the adhesive and the adhesive ring 3, and improve the strength of the bonding structure.

[0034] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
