Description

Technical Field

[0001] The utility model belongs to the technical field of sound, and in particular relates to an anti-resonance sound. Background Art

[0002] As we all know, sound is produced by vibration. For example, in the audio-visual equipment commonly used by people, the main sound-producing part is the speaker. After passing through the driver, the electrical signal is transmitted to the diaphragm and causes it to vibrate. The vibrating diaphragm will produce sound waves in the air, which is the loud sound we hear.

[0003] That is, when the speaker is working, a certain frequency of vibration will be generated inside it, and as the volume is adjusted, the frequency of the vibration will also increase. The high-frequency vibration will cause the installed container (i.e. the speaker) to resonate, and will also demagnetize the internal parts, and even worse, it will cause damage, which is not conducive to the stable operation of the speaker.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Example 1

[0020] like Figures 1 to 4The anti-resonance sound device shown in the figure includes a sound device 1, which is divided into a panel 101 and a side panel 102. The panel 101 is provided with a mounting shell 3, and a speaker body 5 is fixedly mounted on the front side of the mounting shell 3 by bolts 4. The inner sides of the side panels 102 are provided with sliding sleeves 6, and a touch rod 8 is slidably arranged in the sliding sleeves 6 through elastic members 7. The inner sides of the touch rods 8 are rotatably provided with first rollers 9. The rear side of the panel 101 is symmetrically provided with a limit group 10, and the limit group 10 includes a rotating rod 11, a push plate 12 and a second roller 13; the rotating rod 11 is rotatably arranged on the panel 101. On the upper and lower sides, a push plate 12 is rotatably provided on the rotating rod 11, and a second roller 13 is rotatably provided on the inner side of the push plate 12; an extension rod 14 is provided outwardly on the upper and lower outer sides of the middle part of the touch rod 8, and a push wheel 15 is rotatably provided on the extension rod 14, and the push wheel 15 is located on the inner side of the push plate 12; the first roller 9 and the second roller 13 are both covered with rubber rings 16 on the outer sides; the installation shell 3 is connected to the speaker through a threaded component 17, and the threaded component 17 is hollow; a wire groove 18 is provided after the installation shell 3; and shock-absorbing material 19 is filled between the installation shell 3 and the panel 101.

[0021] The utility model further provides a mounting shell 3 on the panel 101 of the speaker 1 through a shock-absorbing material 19, thereby avoiding direct connection between the speaker and the panel 101 of the speaker 1 and reducing the range of resonance; first rollers 9 connected by tension springs are also provided on the left and right sides of the mounting shell 3, and second rollers 13 are linkedly provided on the upper and lower sides of the mounting shell 3, and rubber rings 16 are sleeved on the two rollers. Under the above series of settings, the vibration generated when the speaker makes a sound is offset and weakened, which plays an effective vibration reduction role to a certain extent.

[0022] Example 2

[0023] like Figures 1 to 4 The anti-resonance speaker shown includes a speaker 1. Common speakers 1 are all square containers of certain specifications. This embodiment and the figure do not show them completely. Only the parts that need to be installed are shown, which are divided into a panel 101 and two side panels 102. The panel 101 is provided with a circular groove for installing a cylindrical installation shell 3. The cross-sectional area of ​​the installation shell 3 is smaller than the gasket on the speaker body 5, so that the speaker body 5 can be inserted into the installation shell 3 as a whole, and then the gasket is clamped on the installation shell 3, and then the gasket is fixed to the installation shell 3 by bolts 4, so as to achieve the stable installation of the entire speaker 1. Among them, the shock-absorbing material 19 is filled between the outer side of the installation shell 3 and the panel 101, which ensures that the installation shell 3 is stably installed on the panel 101, and can also prevent the speaker body 5 from directly contacting the panel 101 when making sound and vibrating, resulting in resonance. The shock-absorbing material 19 can be any of the common sponges or silicones on the market.

[0024] The basic vibration reduction arrangement of the speaker body 5 is as follows: a sliding sleeve 6 is arranged inside the side plate 102. The sliding sleeve 6 is arranged in a square shape and is flush with the middle position of the mounting shell 3. When the vibration reduction assembly in the sliding sleeve 6 is in operation, the vibration phenomenon generated by the speaker body 5 can be uniformly reduced. A plurality of elastic members 7 are arranged inside the sliding sleeve 6, which are specifically arranged as a plurality of tension springs, and a touch rod 8 is connected through the tension spring, so that the touch rod 8 can move left and right inside the sliding sleeve 6. A first roller 9 is rotatably arranged inside the touch rod 8. Under the action of the tension spring, the touch rod 8 will move outward until the first roller 9 contacts the mounting shell 3, and under the action of the elastic member 7, the touch rod 8 always keeps in contact with the mounting shell 3.

[0025] That is, when the speaker in the mounting shell 3 is started and gradually performs high-frequency operation to emit vibrations, basic vibration reduction will be achieved through the shock-absorbing material 19, and then the vibration force will spread outward through the mounting shell 3. At this time, the vibration force will spread outward and will first contact the first roller 9, and will be offset to the left and right sides by the elastic member 7 on the outside of the first roller 9, thereby playing a vibration reduction role.

[0026] Example 3

[0027] like Figures 1 to 4 The anti-resonance speaker shown in the figure has a certain vibration reduction effect by arranging slidable first rollers 9 on the left and right sides of the mounting shell 3 and offsetting the vibration force through the force of the tension spring. In order to further increase the vibration reduction effect, second rollers 13 for resisting the vibration force are also arranged on the upper and lower sides of the mounting shell 3, and rubber rings 16 are sleeved on the outer sides of the second rollers 13 and the first rollers 9 to further dampen the vibration force emitted by the speaker. At this time, the rubber ring 16 will replace the contact between the roller and the mounting shell. Under the elastic deformation of the rubber material, the received vibration force can be offset and weakened through its own deformation, achieving a more effective vibration reduction effect.

[0028] Next, the specific installation position of the second roller 13 is the upper and lower sides of the mounting shell 3, and the installation method is rotational installation. A rotating rod 11 is symmetrically provided at the upper and lower positions of the rear side of the panel 101, and a push plate 12 is rotatably provided on the rotating rod 11. The approximate shape of the push plate 12 is an arc of a quarter circle that is adapted to the shape of the mounting shell 3, so that the second roller 13 installed on the inner side of the push plate 12 can be in close contact with the mounting shell 3; and in order to make the second roller 13 always keep in contact with the mounting shell 3, the rotation of the push plate 12 is also linked with the touch rod 8, and the specific linkage method is:

[0029] Extension rods 14 are extended on both sides of the upper and lower parts of the middle of the touch rod 8, and push wheels 15 are rotatably provided on the extension rods 14. The push wheels 15 will be located on the inner side of the push plate 12, and then when the touch rod 8 keeps moving inward under the action of the tension spring, it drives the first roller 9 to keep in contact with the mounting shell 3, and at the same time drives the extension rod 14 to move inward, and then drives the push wheel 15 to move inward and contact with the push plate 12, pushing the push plate 12 to rotate, and rotating the end of the second roller 13 inward until it is in close contact with the mounting shell 3; during this period, the rubber ring 16 can also prevent the second roller 13 from excessively contacting the mounting shell 3, causing the mounting shell 3 to be damaged.

[0030] Example 4

[0031] like Figures 1 to 4 As shown in the figure, it should be noted that the inside of the mounting shell 3 is connected to the speaker via a threaded assembly 17, that is, the speaker can be pre-installed in the mounting shell 3 by rotation, which can further reduce the emergency of the speaker accidentally falling during the installation process; and the threaded assembly 17 is hollow, which can also facilitate the extension of the circuit on the speaker backward for connection and installation. Correspondingly, a wire groove 18 is opened after the mounting shell 3 to facilitate the installation of the circuit on the speaker while supporting the wires connected to the speaker to prevent the wires from falling off in the case of resonance, making the speaker 1 unusable.

[0032] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0033] The above description is only used to illustrate the technical solution of the utility model rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
