Description

Technical Field

[0001] The utility model belongs to the technical field of speaker reinforcement structures, and in particular relates to a speaker reinforcement structure. Background Art

[0002] A speaker, also known as a loudspeaker, is a very common electroacoustic transducer device and is widely used in sound-generating electronic and electrical equipment.

[0003] The magnetic circuit component is the part that generates electromagnetic induction. It is the part with the highest assembly precision of the speaker. The installation positions of the magnetic circuit components and the electrode sensing positions correspond strictly. Any deviation during installation or use will cause some components of the magnetic circuit to shift, which can easily cause rubbing, friction, polarization or uneven vibration of the speaker, resulting in harsh noise and affecting the sound emitted by the speaker.

[0004] At present, the assembly method of magnetic circuit components is to install the washer, magnet and T-iron into a cylindrical structure. The hollow structure is used for the setting of the speaker structure voice coil on the one hand, and for heat dissipation on the other hand. The washer and magnet are designed to be cylindrical and mounted on the T-iron. The T-iron is a boss structure design and is hollow. The bottom surface of the magnetic circuit component is a circular ring with a certain width. Generally, the inner diameter of the washer is designed to be smaller than the inner diameter of the magnet so that it can be connected to the basin frame or other fixed structures.

[0005] At present, simple screws are mainly used to connect the magnetic circuit components and the base to fix the magnetic circuit components as a whole, or fixing glue is used to achieve the bonding of the various components of the speaker magnetic circuit. These applications are relatively widespread in small speakers. However, when the speakers are used in large-scale production equipment that requires vibration, the vibration amplitude of the large equipment is too large, and accordingly, the vibration amplitude of the magnetic circuit components is also large. Simple screw fixing or fixing glue cannot meet the seismic conditions required for the normal operation of the speaker.

[0006] In order to solve the above problems, the present invention proposes a method of using a bracket to fix the connection between the magnetic circuit component and the basin frame in the magnetic circuit component to further improve the shockproof ability of the magnetic circuit component to meet the shockproof conditions required for installing speakers on large vibration equipment. Utility Model Content

[0009] The purpose of the utility model can be achieved through the following technical scheme: comprising a bracket, the bracket comprising a top connecting section, a bracket beam, a bottom connecting section and a bottom rod, the bracket beam is attached to the side surface of the magnetic circuit component of the speaker structure, the upper end of the bracket beam is hinged to the basin frame of the speaker structure through the top connecting section, the lower end of the bracket beam is hinged to the bottom rod through the bottom connecting section, the bottom rod is attached to the bottom surface of the magnetic circuit component, and one end of the bottom rod is hinged to the bottom surface of the magnetic circuit component, the bracket is an integrated structure and abuts against the surface of the magnetic circuit component, and two brackets are symmetrically arranged about the axis of the magnetic circuit component.

[0010] Preferably, the hinge point between the bottom rod and the magnetic circuit component is located at the inner ring edge of the magnetic circuit component.

[0011] Preferably, the bottom rod is detachably connected to the bottom surface of the magnetic circuit component by bolts.

[0012] Preferably, the bracket further includes an extension portion, and the top connecting section is detachably connected to the basin frame via the extension portion.

[0013] Preferably, two of the brackets are symmetrically arranged about the axis of the magnetic circuit component of the speaker structure, and the angle between the four brackets is 90°.

[0014] Preferably, a stepped block is provided on the contact surface between the top connecting section and the magnetic circuit component.

[0015] Preferably, the bracket is formed with an embedding groove on its outer wall surface, and a support beam is embedded in the embedding groove.

[0016] Preferably, limiting blocks are symmetrically arranged on the edges of the groove openings of the embedding grooves, and the limiting blocks abut against the support beams.

[0017] The beneficial effects of the utility model are:

[0018] The present invention is a bracket designed by reinforcing the loudspeaker magnetic circuit component. The upper end of the bracket is connected to the basin frame through an extension portion, and the lower end of the bracket is connected to the lower surface of the magnetic circuit component, fixing the magnetic circuit component and the basin frame, thereby reinforcing the loudspeaker structure.

[0025] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0026] See also Figure 1-Figure 3 , this embodiment provides a reinforcement bracket for a speaker, including a bracket;

[0027] The bracket includes a top connecting section, a bracket beam, a bottom connecting section and a bottom rod. The bracket beam 13 abuts against the side surface of the magnetic circuit component 2. The upper end of the bracket beam 13 is detachably connected to the lower end of the basin frame 3 of the speaker structure through a top connecting structure. The detachable connection method can be selected from threaded connection, pin connection or key connection. The lower end of the bracket beam 13 is hinged with the bottom rod 11 through the bottom connecting section 12. The hinged structure can adopt snap-on hinge, plane hinge and other methods according to actual needs. The bottom rod 11 is attached to the bottom surface of the magnetic circuit component 2, and one side of the bottom rod 11 is hinged to the bottom surface of the magnetic circuit component 2. Any bracket is an integrated structure in which various parts are connected. The shapes of the top connecting section 14 and the bottom connecting section 12 can be designed according to the shape of the magnetic circuit component 2 under actual conditions to achieve surface abutment between the bracket and the magnetic circuit component 2. Two brackets are symmetrically arranged about the axis of the magnetic circuit component 2 of the speaker, and the two brackets are mirror structures.

[0028] Furthermore, in order to improve the reinforcement of the bracket to the magnetic circuit component 2, in the present embodiment, the hinge point between the bottom rod 11 and the bottom surface of the magnetic circuit component 2 is located at the edge of the inner ring of the magnetic circuit component 2, and the hinge point between the bottom rod 11 of the bracket and the bottom surface of the magnetic circuit component 2 forms a ring on the same plane, which makes the force more uniform. The length of the bottom rod 11 is designed to match the diameter difference between the outer ring and the inner ring of the magnetic circuit component 2, thereby ensuring that the contact area between the bottom rod 11 and the bottom surface of the magnetic circuit component 2 is maximized, thereby improving the force stability of the bracket and the reinforcement of the bracket.

[0029] Furthermore, in order to improve the connection stability between the bracket and the basin frame 3, the bracket in this embodiment also includes an extension portion 15, and one end of the bracket beam 13 is detachably connected to the lower end portion of the basin frame 3 structure of the speaker through the extension portion 15. The connection method can be a threaded connection, a pin connection or a key connection. The extension portion 15 is used to increase the area of ​​the connection point between the bracket and the basin frame 3, thereby improving the connection strength between the bracket and the basin frame 3.

[0030] Furthermore, in order to reduce the interference of the bracket's own material on the magnetic field of the speaker's magnetic circuit component 2, in the present embodiment, one side of the bottom rod 11 is detachably connected to the bottom surface of the magnetic circuit component 2 by a bolt 6, and the outer surface of the bottom rod 11 is in contact with the magnetic circuit component 2. The material of the bolt 6 should be a magnetic material having a magnetic permeability close to that of the magnetic circuit component 2, or a material that has no magnetic conductivity at all, so as to avoid interference with the electromagnetic induction of the magnetic circuit component 2 itself by adding non-magnetic materials.

[0031] Furthermore, in order to improve the reinforcement capability of the bracket, in the present embodiment, two brackets are added which are mirror images of the brackets in the aforementioned embodiment, and the two newly added brackets are still designed to be axially symmetrical about the magnetic circuit component 2. Following the aforementioned embodiment, the angles between the planes in which the four brackets are located are 90°, that is, the four bottom rods 11 are arranged on two mutually perpendicular central axes on the bottom surface of the magnetic circuit component 2, since the magnetic circuit component 2 is a hollow structure; optionally, according to the stress conditions, the number of brackets can be cyclically increased in the manner of the present embodiment until the reinforcement requirements are met.

[0032] In order to further improve the fit between the bracket and the magnetic circuit component 2, in the present embodiment, a stepped block 7 is provided at the fitting position between the top connecting section 14 and the outer edge of the washer 21 of the magnetic circuit component 2. Since the inner diameter of the washer 21 of the magnetic circuit component 2 is generally designed to be smaller than the inner diameter of the magnetic steel of the magnetic circuit component 2, a raised annular structure will appear between the annular washer 21 and the magnetic steel. Therefore, the stepped block 7 is designed to cooperate with the protruding washer 21 circular ring. The design of the stepped block 7 increases the contact area between the bracket and the magnetic circuit component 2, thereby improving the reinforcement of the bracket.

[0033] Furthermore, under the large vibration of the large speaker, the use of metal materials to make the bracket can meet the required firmness of the bracket, but the metal bracket is easy to slip under the large vibration of the large speaker, which will affect the stability of the speaker itself; if it is made of plastic material, it cannot meet the required reinforcement of the bracket and the required tightness of the speaker bracket. If it is made of hard plastic, the hard plastic will have a certain fragility. Therefore, based on the above considerations, in this embodiment, the bracket is formed with a groove on its outer wall surface, and a support beam 41 is embedded in the groove. The groove and the surface of the magnetic circuit component 2 are abutted, and the support beam 41 is embedded in the groove. The support beam 41 is made of metal material, and metal materials such as copper, aluminum or steel can be used, and other synthetic metals can also be used to meet the required firmness and tightness of the bracket and are not easy to deform; the groove is made of plastic material, such as PVC plastic, silicone material or EVA material, which can play a buffering role on the overall structure of the speaker when the large speaker generates a large vibration, and the groove and the support beam 41 are further fixed by bolts 6.

[0034] Furthermore, when the large speaker vibrates, the entire speaker may translate or move in other ways, which may affect the stability of the bracket at the bottom of the magnetic circuit component 2 of the speaker. In order to improve the stability of the bracket bottom rod 11, in this embodiment, the edge of the groove of the bottom rod 11 is symmetrically provided with a limit block 5, and the outer side of the support beam 41 is against the limit block 5. When the large speaker generates a large vibration, the limit block 5 can fix the support beam 41 in a relatively translated position.

[0035] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
