Abstract
The utility model relates to a novel speaker. In the speaker, the bottom of a diffuser support is provided with a groove; a magnetic circuit system is arranged in the groove; thus the structure is simpler; the costs are lower; and the speaker is thinner. The speaker comprises the diffuser support and the magnetic circuit system; and the speaker is characterized in that the bottom of the diffuser support is provided with a groove and the magnetic circuit system is arranged in the groove. The groove is made of magnetism-conductive metal material, which can enhance the magnetism of the magnetic circuit system. The arrangement of the magnetic circuit system in the groove reduces the thickness of the speaker. No matter the technical proposal is used in a cone speaker or a flat-panel speaker, the thickness of the speaker can be reduced further; and the products are thinner compared with the speaker of the same category.
Description
Technical field
The utility model relates to a kind of loud speaker, especially relates to a kind of bottom at the basin frame and is provided with groove, is provided with magnetic circuit system in the groove, makes that structure is comparatively simple, cost is lower and more frivolous New-type loudspeaker.
Background technology
Traditional awl benzvalene form loud speaker has generally comprised vibrating diaphragm, voice coil loudspeaker voice coil, basin frame and magnetic circuit system, the aperture circular hole suitable mutually with voice coil loudspeaker voice coil offered in the bottom of basin frame, by voice coil loudspeaker voice coil magnetic circuit system and vibrating diaphragm are interconnected and since its basin frame be taper make that the thickness of loud speaker is generally all thicker.Growing along with science and technology, consumer electronics are to miniaturization, slimming development, loud speaker also at leisure from traditional awl benzvalene form to plate development, flat-plate loudspeaker is also used by increasing people, but, no matter be awl benzvalene form loud speaker or flat-plate loudspeaker, their magnetic circuit system normally is arranged on the below of basin frame, and this just makes that the thickness of loud speaker can't further be reduced.
The utility model content
The utility model mainly is the technical problem that the thickness of solution existing in prior technology loud speaker can't further be reduced grade, provide a kind of bottom to be provided with groove at the basin frame, magnetic circuit system is arranged in the groove, makes that structure is comparatively simple, cost is lower and more frivolous New-type loudspeaker.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of loud speaker, include basin frame and magnetic circuit system, and it is characterized in that: the bottom of described basin frame is provided with groove, and magnetic circuit system is located in the groove.Bottom at the basin frame is provided with groove, groove is formed by the metal material manufacturing of magnetic conduction, can increase the magnetic of magnetic circuit system, magnetic circuit system is arranged in the groove, thereby reduced the thickness of loud speaker, no matter be to be applied to bore benzvalene form loud speaker or flat-plate loudspeaker, can further reduce the thickness of loud speaker, it is thinner that the product of producing is compared similar loud speaker.
As preferably, described magnetic circuit system is made up of main magnet and magnetic conductive board, and magnetic conductive board is located at the top of main magnet.Magnetic circuit system is made up of main magnet and magnetic conductive board, and structure is very simple, and production cost is low.
As preferably, the bottom of described basin frame is for sealing.The bottom of basin frame makes the utility model not fragile for what seal.
As preferably, described groove and the coaxial setting of basin frame.Groove and the coaxial setting of basin frame help reducing the thickness of basin frame.
As preferably, described magnetic circuit system and the coaxial setting of basin frame.Magnetic circuit system and the coaxial setting of basin frame make that the assembling of magnetic circuit system and basin frame is comparatively tight, help reducing the volume and the thickness of basin frame.
As preferably, described groove is located at the center of basin frame bottom.
As preferably, the end face of described magnetic conductive board also is provided with secondary magnet.The end face of magnetic conductive board also is provided with secondary magnet, sets up the magnetic flux density that secondary magnet can increase magnetic circuit system.
Therefore, the utlity model has following characteristics: 1. magnetic circuit system is made up of main magnet and magnetic conductive board, and is simple in structure, reasonable in design; 2. be provided with groove in the bottom of basin frame, magnetic circuit system is arranged in the groove, make that thickness of the present utility model is less; 3. the end face of magnetic conductive board also is provided with secondary magnet, thereby magnetic circuit system has higher magnetic flux density.
Description of drawings
Accompanying drawing 1 is the cutaway view of a kind of structural representation of the present utility model.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1: a kind of loud speaker, include basin frame 1 and magnetic circuit system 2, and the bottom of basin frame 1 is for what seal, and magnetic circuit system 2 is made up of main magnet 21 and magnetic conductive board 22, and magnetic conductive board 22 is located at the top (referring to accompanying drawing 1) of main magnet 21.The bottom of basin frame 1 is provided with groove 3, and groove 3 is located at the center of basin frame 1 bottom, and groove 3 and the 1 coaxial setting of basin frame, and magnetic circuit system 2 is located in the groove 3 (referring to accompanying drawing 1).Magnetic circuit system 2 is made up of main magnet 21 and magnetic conductive board 22, and structure is very simple, and production cost is low.No matter magnetic circuit system 2 is arranged in the groove 3, has reduced the thickness of loud speaker, be to be applied to bore benzvalene form loud speaker or flat-plate loudspeaker, can further reduce the thickness of loud speaker, and it is thinner that the product of producing is compared similar loud speaker.Magnetic circuit system 2 and the 1 coaxial setting of basin frame.In order to increase the magnetic flux density of magnetic circuit system 2, also can be provided with a secondary magnet 23 at the end face of magnetic conductive board 22.
It is apparent to one skilled in the art that the utility model can be changed into multiple mode, and such change is not thought and broken away from scope of the present utility model.What all were such will be included within the scope of this claim the conspicuous modification of described those skilled in the art.
