Abstract
The invention discloses a three-magnet loudspeaker comprising an upper bracket, a vibrating diaphragm, a voice coil, a bracket, auxiliary washers, auxiliary magnets, a main washer, a main magnet and an iron block. By the three-magnet loudspeaker, quality of sound of the loudspeaker can be well guaranteed, and distortion is avoided; besides, the three-magnet loudspeaker is compact in structure, stable after being installed, less prone to fault during use and applicable to equipment such as laptops, tablet computers, cameras and game machines needing high-end loudspeakers.
Description
Technical field
The present invention relates to earphone field, particularly relate to a kind of three magnet loudspeaker.
Background technology
Earphone is a kind of electronic product conventional in life.The loudspeaker of earphone generally include frame (or support), about iron (or base), magnet, voice coil loudspeaker voice coil, vibrating diaphragm, upper cover (or upper bracket).When after voice coil loudspeaker voice coil energising, become electromagnet, along with the change of signal, the magnetic field that electromagnet produces along with changing, can produce active force with magnet, Continuous Drive vibrating diaphragm vibrations sounding.Existing loudspeaker are all arrange a magnet usually, and the problem of distortion easily appears in the tonequality sent.
Summary of the invention
Therefore, it is good that the technical problem to be solved in the present invention is to provide a kind of tonequality, three magnet loudspeaker of not easily distortion.
To achieve these goals, a kind of three magnet loudspeaker of the present invention, comprise upper bracket, vibrating diaphragm, voice coil loudspeaker voice coil, support, secondary washer, secondary magnet, main washer, main magnet, about iron, wherein said main magnet, secondary magnet are positioned at the upper surface of about iron, main magnet is positioned at about iron upper surface centre position, and two secondary magnet lay respectively at the both sides of main magnet; Described main washer is positioned on the upside of main magnet, and two secondary washers respectively correspondence are positioned on the upside of two secondary magnet; Described two secondary magnet be provided with gap between described main magnet and gap width between each secondary magnet and described main magnet is identical, described voice coil loudspeaker voice coil inserts in described gap; The upper end of described voice coil loudspeaker voice coil is connected with described vibrating diaphragm, and upper bracket is positioned at the upside of described vibrating diaphragm.
Described support is a ring frame, and described upper bracket is positioned at the upside of described support; Described main magnet, secondary magnet, main washer, secondary washer, voice coil loudspeaker voice coil, vibrating diaphragm are positioned at described support.
The middle part of described upper bracket offers sound mouth.
Described about iron comprises horizontally disposed flat part and is positioned at described flat part both sides and the vertical portion extended straight up, and the side of described upper bracket be provided with accommodation section corresponding to described vertical portion is for holding described vertical portion.
The inwall of described support is provided with shoulder structure, the lateral edges of described vibrating diaphragm is overlapped in described shoulder structure.
Adopt technique scheme, three magnet loudspeaker of the present invention, can ensure that loudspeaker go out the tonequality of sound preferably, avoid distortion, and compact conformation, comparatively firm after installation, not easily break down in using, be suitable for the equipment that notebook, panel computer, camera, game machine etc. need high-end loudspeaker.
Accompanying drawing explanation
Fig. 1 is the structural representation of loudspeaker of the present invention.
Embodiment
Below by way of the drawings and specific embodiments, the present invention is described in further detail.
As shown in Figure 1, the present embodiment provides a kind of three magnet loudspeaker, comprise upper bracket 1, vibrating diaphragm 2, voice coil loudspeaker voice coil 3, support 4, secondary washer 5, secondary magnet 6, main washer 7, main magnet 8, about iron 9, wherein said main magnet 8, secondary magnet 6 are positioned at the upper surface of about iron 9, main magnet 8 is positioned at about iron 9 upper surface centre position, and two secondary magnet 6 lay respectively at the both sides of main magnet 8; Described main washer 7 is positioned on the upside of main magnet 8, and two secondary washers 5 respectively correspondence are positioned on the upside of two secondary magnet 6; Described two secondary magnet 6 be provided with gap between described main magnet 8 and gap width between each secondary magnet 6 and described main magnet 8 is identical, described voice coil loudspeaker voice coil 3 inserts in described gap; The upper end of described voice coil loudspeaker voice coil 3 is connected with described vibrating diaphragm 2, and upper bracket 1 is positioned at the upside of described vibrating diaphragm 2.
Described support 4 is a ring frame, and described upper bracket 1 is positioned at the upside of described support 4; Described main magnet 8, secondary magnet 6, main washer 7, secondary washer 5, voice coil loudspeaker voice coil 3, vibrating diaphragm 2 are positioned at described support 4.
The middle part of described upper bracket 1 offers sound mouth.
Described about iron 9 comprises horizontally disposed flat part 9a and is positioned at described flat part 9a both sides and the vertical portion 9b extended straight up, and the side of described upper bracket 1 be provided with accommodation section 1b corresponding to described vertical portion 9b is for holding described vertical portion 9b.
The inwall of described support 4 is provided with shoulder structure 4a, and the lateral edges of described vibrating diaphragm 2 is overlapped on described shoulder structure 4a.
Adopt technique scheme, three magnet loudspeaker of the present invention, can ensure that loudspeaker go out the tonequality of sound preferably, avoid distortion, and compact conformation, comparatively firm after installation, not easily break down in using, be suitable for the equipment that notebook, panel computer, camera, game machine etc. need high-end loudspeaker.Obviously, above-described embodiment is only for clearly example being described, and the restriction not to execution mode.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all execution modes.And thus the apparent change of extending out or variation be still among the protection range of the invention.
