Abstract
The invention relates to an ultrathin electric speaker, belonging to the field of speakers. The invention has the main technical characteristics that U iron is in a runner shape, sticking area of the middle of the U iron and a main magnet is projected, so that the vibration distance between the upper and the lower of a voice coil is increased; and the bottom surface of U iron is provided with an aluminium gasket, the heat dissipation area is increased, and the magnetic efficiency of the magnet of a magnetic circuit is improved. According to the invention, the vibration distance of the voice coil is increased, the power of the speaker is improved, simultaneously, the heat dissipation area is increased, the magnetic efficiency of the magnet of the magnetic circuit is improved, so that the condition that the voice coil is too hot to be damaged and burnt out can be avoided.
Description
One, technical field
The invention belongs to the loud speaker field, especially relevant with a kind of ultra-thin electrodynamic loudspeaker.
Two, background technology
Ultra-thin television (like LCD, plasma, LED, OLED TV) is the main flow of existing market, because ultra-thin television is done thinner and thinner, causes the acoustic design limitation of ultra-thin television increasing thus.The maximum problem of limitation is how to solve the spatial volume minor issue of ultra-thin television sound box system, makes small-bore loud speaker have enough big power to satisfy the needs of acoustic pressure.Present method all focuses on the flat narrow speaker design; Long axis direction is not too restricted in the narrow flat speaker design process, but short-axis direction just can't design its limitation with placement space, and in case reduce speaker port footpath area; It is just little that sound sounds; If there have loud noise to add to be high-power, voice coil loudspeaker voice coil work will strengthen the generation heat like this, and voice coil loudspeaker voice coil is burnt out.
In order to address the above problem; Many current methods are in magnetic circuit, to add magnetic liquid, but the purpose of these schemes all is to make heat radiation to accelerate, and can't improve power; And magnetic liquid is price high (generally at 2000 yuan) not only, and is placed into loud speaker that effect is not very desirable in the casing of sealing.
Three, summary of the invention
The object of the invention will overcome above-mentioned defective exactly, provides that a kind of cost is low, power is big and the loud speaker of thin thickness.For this reason, the present invention adopts following technical scheme:
A kind of ultra-thin electrodynamic loudspeaker; Comprise U iron, main magnet, secondary magnet, magnetic conduction sheet, voice coil loudspeaker voice coil, locating branch slice, complex tone basin, paper cap, terminal block and plastic tub frame, U iron, main magnet, secondary magnet and magnetic conduction sheet are formed the magnetic circuit system of loudspeaker, and voice coil loudspeaker voice coil, complex tone basin and locating branch slice are formed the vibrational system of loudspeaker; Voice coil loudspeaker voice coil is track shape and can in magnetic gap, does the bi-directional axial motion; Voice coil loudspeaker voice coil is connected with paper cap with the complex tone basin through skeleton, and complex tone basin and locating branch slice are fixedly mounted on the plastic tub frame, and locating branch slice is connected with the complex tone basin makes the complex tone basin be in suspended state; Terminal block connects voice coil loudspeaker voice coil through lead wire; It is characterized in that: described U iron is track shape, and is middle protruding with main magnet bond area part, increases the oscillation distances of voice coil loudspeaker voice coil between up and down; The bottom surface of described U iron is provided with aluminium backing, has increased area of dissipation, improves the magnet magnetic efficient of magnetic circuit, makes voice coil loudspeaker voice coil can not cross cause thermal damage and causes burning circle.
The present invention has the following advantages:
1, increases the oscillation distances of voice coil loudspeaker voice coil, improved the power of loud speaker.
2, increased area of dissipation, improved the magnet magnetic efficient of magnetic circuit, made voice coil loudspeaker voice coil can not cross cause thermal damage and cause burning circle.
Four, description of drawings
Fig. 1 is a cutaway view of the present invention.
Wherein, 1, U iron; 2, main magnet; 3, magnetic conduction sheet; 4, secondary magnetic sheet; 5, voice coil loudspeaker voice coil; 6, locating branch slice; 7, aluminium backing; 8, plastic tub frame; 9, complex tone basin; 10, paper cap; 11, terminal block.
Five, embodiment
Be described in detail below in conjunction with the accompanying drawing specific embodiments of the invention.
As shown in Figure 1, the present invention includes track shape U iron 1, main magnet 2, secondary magnet 4, magnetic conduction sheet 3, track shape voice coil loudspeaker voice coil 5, locating branch slice 6, complex tone basin 9, paper cap 10, terminal block 11, plastic tub frame 8, U iron 1, main magnet 2, secondary magnet 4 and magnetic conduction sheet 3 are formed the magnetic circuit system of loudspeaker; Voice coil loudspeaker voice coil 5, complex tone basin 9 and locating branch slice 6 are formed the vibrational system of loudspeaker; Track shape voice coil loudspeaker voice coil 5 can be done the bi-directional axial motion in magnetic gap, voice coil loudspeaker voice coil 5 is connected with paper cap 10 with complex tone basin 9 through skeleton, and complex tone basin 9 is fixedly mounted on the plastic tub frame 8 with locating branch slice 6; Locating branch slice 6 is connected with complex tone basin 9 makes complex tone basin 9 be in suspended state; Terminal block 11 connects voice coil loudspeaker voice coil 5 through lead wire, and is protruding with main magnet bond area part in the middle of the track shape U iron 1, increases the oscillation distances of voice coil loudspeaker voice coil between about in the of 5; The bottom surface of track shape U iron 1 also is provided with aluminium backing 7; Increased area of dissipation, improved the magnet magnetic efficient of magnetic circuit, made voice coil loudspeaker voice coil 5 can not cross cause thermal damage and cause burning circle.
