Description

Technical Field

[0001] The present invention relates to the technical field of speakers, and particularly to a distortion-proof loudspeaker. Background Art

[0002] Loudspeakers are common and used items in our daily life. They can play sound externally and are also an important part of speakers.

[0003] In existing loudspeakers, only one magnet is sleeved on the iron core of its component parts. When playing at high power, sound distortion is likely to occur. Moreover, the cost of a whole magnet adapted to the iron core is much higher than that of two spliced magnets, especially for loudspeakers above 120 magnets, the cost gap is more obvious. Summary of the Invention

[0004] The present invention provides a distortion-proof loudspeaker, which can effectively prevent the occurrence of sound distortion in the loudspeaker and can minimize the manufacturing cost of the loudspeaker.

[0005] To achieve the above object, the present invention adopts the following technical solutions: A distortion-proof loudspeaker includes a loudspeaker body. There is an iron core and a magnet at the rear end of the loudspeaker body. It is characterized in that the magnet includes a first magnet and a second magnet. The first magnet is sleeved on the iron core, and the second magnet is sleeved on the first magnet. A copper foil is arranged between the first magnet and the second magnet. The copper foil is attached to the outer edge surface of the first magnet to prevent sound distortion.

[0006] Preferably, the first magnet and the second magnet have the same thickness.

[0007] Compared with the prior art, the beneficial effect of the present invention is that it can effectively reduce the sound distortion rate and greatly reduce the production cost. Brief Description of the Drawings

[0008] Figure 1 It is a three-dimensional structure schematic diagram of the present invention; Figure 2 It is a front view of the assembly of the iron core and the magnet of the present invention; Figure 3 It is an exploded view of the iron core and the magnet of the present invention. Detailed Description of the Embodiments

[0009] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0010] It should be noted that when a component / part is referred to as being "set on" another component / part, it may be directly set on the other component / part or there may also be an intermediate component / part. When a component / part is referred to as being "connected / coupled" to another component / part, it may be directly connected / coupled to the other component / part or there may be an intermediate component / part at the same time. The term "connection / coupling" as used herein may include electrical and / or mechanical physical connections / couplings. The term "includes / comprising" as used herein refers to the presence of a feature, step or component / part, but does not exclude the presence or addition of one or more other features, steps or components / parts. The term "and / or" as used herein includes any and all combinations of one or more relevant listed items.

[0011] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0012] In addition, in the description of this application, the terms "first", "second", etc. are only used for descriptive purposes and to distinguish similar objects. There is no order of precedence between the two, and they cannot be understood as indicating or implying relative importance. In addition, in the description of this application, unless otherwise specified, the meaning of "plurality" is two or more.

[0013] See also Figures 1 to 3 As shown, an anti-distortion speaker includes a speaker body 1, and the speaker body 1 includes the components of the existing speaker. Because it is a prior art, it is not described in detail. An iron core 2 and a magnet 3 are provided on the rear end of the speaker body 1. The iron core 2 is a conventional T-shaped iron core. The magnet 3 includes a first magnet 31 and a second magnet 32. The first magnet 31 is sleeved on the iron core 2. The middle of the first magnet 31 has a through hole that is compatible with the iron core 2. The protruding end of the iron core 2 can be inserted into the through hole to achieve assembly with the first magnet 31.

[0014] There is an assembly hole in the middle of the second magnet 32, the diameter of which is slightly larger than that of the first magnet 31. The second magnet 32 ​​is sleeved on the first magnet 31 through the assembly hole. A copper foil 4 is arranged between the first magnet 31 and the second magnet 32. The copper foil 4 is attached to the outer edge surface of the first magnet 31 to prevent sound distortion and improve sound quality.

[0015] In some embodiments, in addition to the copper foil 4 , other metal foils may also be used, and the first magnet 31 and the second magnet 32 ​​have the same thickness.

[0016] The present invention can effectively reduce the sound distortion rate and greatly reduce the production cost.

[0017] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
