Abstract
The utility model discloses the magnetic circuit oscillating loudspeaker in the electroacoustic industry, comprising a magnet, a magnetic conduction block, a speech coil, an outer shell and a fixing cover. The magnetic conduction block is bonded on the magnet which is suspended in a centering ring. Because the magnet can oscillate up and down in the centering ring, the loudspeaker can generate low low-frequency response effect.
Description
Technical field
The utility model relates to a kind of electro-acoustic product, specifically a kind of magnetic circuit vibrating speaker.
Background technology
For a long time, the magnetic field that ventional loudspeakers utilizes magnet to produce in the working region of voice coil loudspeaker voice coil makes tone currents produce cutting movement by voice coil loudspeaker voice coil in magnetic field, produces up-down vibration, forms dilatational wave and produce sound in air thereby drive the sound basin.But in this loud speaker, fixed by the magnetic circuit that magnet constitutes, the vibration of sound basin comes from that voice coil loudspeaker voice coil produces in magnetic field try hard to recommend is moving, so it is difficult to reach and is lower than the following bass effect of 20Hz.
Summary of the invention
The technical problems to be solved in the utility model is at above-mentioned deficiency, designs a kind of magnetic circuit vibrating speaker.
The technical solution of the utility model is: it comprises magnet, magnetic inductive block, voice coil loudspeaker voice coil, shell and fixed cap, and magnetic inductive block is bonded on the magnet, and magnet is suspended in the centering ring.
The audio signal that voice coil loudspeaker voice coil of the present utility model is received, the power that under the effect in magnetic field, produces, promotion be the up-down vibration of magnet in centering ring, so can make loud speaker produce very low LF-response effect, generally can be lower than 10Hz.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The utility model is described in further detail below in conjunction with drawings and Examples.
As shown in the figure, the utility model comprise a magnet 8, magnetic inductive block 3 and magnetic inductive block 6, voice coil loudspeaker voice coil 12 and voice coil loudspeaker voice coil 15, shell 11 and fixed cap 5 and fixed cap 5 ', magnetic inductive block 3 and magnetic inductive block 6 are bonded in the upside and the downside of magnet 8 respectively.End face at magnetic inductive block 2 and magnetic inductive block 6 is stained with vibration absorber 2 and vibration absorber 7 respectively.The magnet 8 that is bonded with magnetic inductive block 2 and magnetic inductive block 6 is suspended in the centering ring 9.Centering ring 9 two outer ends are with magnetic guiding frame 13 and magnetic guiding frame 14, are placed with voice coil loudspeaker voice coil 12 in the magnetic guiding frame 13, are placed with voice coil loudspeaker voice coil 15 in the magnetic guiding frame 14.Be pressed with magnetic conduction sheet 10 on the voice coil loudspeaker voice coil 12, be pressed with magnetic conduction sheet 1 on the voice coil loudspeaker voice coil 15.Just voice coil loudspeaker voice coil 12 and voice coil loudspeaker voice coil 15 compress in north respectively for magnetic conduction sheet 10 and magnetic conduction sheet 1.
Operation principle of the present utility model is: after audio signal is input in voice coil loudspeaker voice coil 12 and the voice coil loudspeaker voice coil 15, in magnetic field, produce a kind of motive force, promotion is partly made up-down vibration by the magnetic circuit that magnet 8 constitutes, thereby make loud speaker produce very low acoustic frequency response effect, make loud speaker send the bass sound of a kind of 10Hz of being lower than.
Claims (6)
