The moving magnet type vibration speaker comprises a fixing seat, a U-yoke, a vibration plate, a voice coil, a washer and a magnet. An elastic support piece is fixed to the upper end of the fixing seat, the vibration plate and the U-yoke are arranged on upper and lower sides of the support piece respectively, the middle of the U-yoke is fixedly connected with the middle of the support piece, and the middle of the vibration plate is fixedly connected with the middle of the support piece. The magnet is fixed to the lower end of the U-yoke, the washer is fixed to the lower end of the magnet, and the center of each of the magnet and the washer is provided with a vertically through center hole. The voice coil is fixed to the fixing seat, the upper portion of the voice coil extends into the center holes of the magnet and the washer in a clearance fit manner, a center column protruding downwards is formed at the lower end of the U-yoke and is inserted into the center holes of the magnet and the washer in a clearance fit manner and inserted into an annular hole of the voice coil in a clearance fit manner. The moving magnet type vibration speaker is excellent in tone quality.
Description
Technical field
The present invention relates to electroacoustic apparatus technology, particularly relate to the technology of a kind of moving-magnetic type vibrating speaker.
Background technology
In existing vibrating speaker, magnetic circuit unit is all fixing, dynamic ferrum oscillating component is subject to magnetic field impact and is constantly in absorbed state, dynamic ferrum oscillating component is made to need bigger elastic force to support, thus causing that the lowest resonance frequency of speaker is in the state that comparison is high, and then have influence on the tonequality of speaker.
Summary of the invention
For the defect existed in above-mentioned prior art, the technical problem to be solved is to provide the moving-magnetic type vibrating speaker that a kind of tonequality is good.
In order to solve above-mentioned technical problem, a kind of moving-magnetic type vibrating speaker provided by the present invention, it is characterised in that: include fixing seat, U ferrum, oscillating plate, voice coil loudspeaker voice coil, washer, Magnet；
The upper end of described fixing seat is fixed with one and has elastic sheet, and described oscillating plate, U ferrum are placed in the both sides up and down of sheet, and affixed in the middle part of the middle part of U ferrum and a sheet, affixed in the middle part of the middle part of oscillating plate and a sheet；
Described Magnet is fixed on the lower end of U ferrum, and washer is fixed on the center of the lower end of Magnet, Magnet and washer and all offers the mesopore of up/down perforation；
Described voice coil loudspeaker voice coil is fixed on fixing seat, the mesopore of Magnet and washer is stretched into gap fiting mode in the top of voice coil loudspeaker voice coil, the lower end of U ferrum is formed with a downwardly projecting center pillar, and this center pillar inserts the mesopore of Magnet and washer with gap fiting mode, and inserts the annular distance of voice coil loudspeaker voice coil with gap fiting mode.
Moving-magnetic type vibrating speaker provided by the invention, the mode utilizing voice coil loudspeaker voice coil cutting magnetic circuit makes U ferrum, washer, Magnet vibrate, by the dynamic oscillating plate thermal vibration sounding of U sheet iron strip, this magnetic circuit unit adopts the mode of on-fixed design to require relatively low to the resilient support of a sheet, the lowest resonance frequency of sheet can be propped up, it is thus possible to improve the tonequality of speaker according to designing requirement adjustment.

Fig. 1 is the three-dimensional exploded view of the moving-magnetic type vibrating speaker of the embodiment of the present invention；
Fig. 2 is the cut away view of the moving-magnetic type vibrating speaker of the embodiment of the present invention.
Detailed description of the invention
Illustrate embodiments of the invention are described in further detail below in conjunction with accompanying drawing; but the present embodiment is not limited to the present invention; the analog structure of every employing present invention and similar change thereof, all should list protection scope of the present invention in, and the pause mark in the present invention all represents the relation of sum.
As Figure 1-Figure 2, a kind of moving-magnetic type vibrating speaker that the embodiment of the present invention provides, it is characterised in that: include fixing seat 1, U ferrum 4, oscillating plate 2, voice coil loudspeaker voice coil 7, washer 6, Magnet 5；
The upper end of described fixing seat 1 is fixed with one and has elastic sheet 3, and described oscillating plate 2, U ferrum 4 are placed in the both sides up and down of sheet 3, and affixed in the middle part of the middle part of U ferrum 4 and a sheet 3, affixed in the middle part of the middle part of oscillating plate 2 and a sheet 3；
Described Magnet 5 is fixed on the lower end of U ferrum 4, and washer 6 is fixed on the lower end of Magnet 5, and the center of Magnet 5 and washer 6 all offers the mesopore of up/down perforation；
Described voice coil loudspeaker voice coil 7 is fixed on fixing seat 1, Magnet 6 and the mesopore of washer 6 are stretched in the top of voice coil loudspeaker voice coil 7 with gap fiting mode, the lower end of U ferrum 4 is formed with a downwardly projecting center pillar 41, this center pillar 41 inserts the mesopore of Magnet 5 and washer 6 with gap fiting mode, and inserts the annular distance of voice coil loudspeaker voice coil 7 with gap fiting mode.
The operation principle of the embodiment of the present invention is as follows:
Fixing seat 1, oscillating plate 2, a sheet 3 constitute vibration unit, and U ferrum 4, washer 6, Magnet 5 constitute magnetic circuit unit, and its magnetic structure is: from the N pole of Magnet, successively through, bottom U ferrum, after center pillar 41, washer 6, arriving at the S pole of Magnet；
To voice coil loudspeaker voice coil 7 input exchange signal during work, voice coil loudspeaker voice coil 7 is cutting magnetic line between washer 6 and center pillar 41, so that U ferrum produces vibration, the vibration of U ferrum is transferred to sheet and an oscillating plate, so that oscillating plate produces sound.
