Abstract
The invention discloses an ultrathin flat plate speaker using double location support chips. The ultrathin flat plate speaker using double location support chips comprises a basin frame and a magnetic path. The magnetic path is composed of a U-shaped iron, magnetic steel and a washer. Two or more than two magnetic paths are arranged on the middle portion of the basin frame. Two ends of the basin frame are provided with two semi-circle-shaped location support chips. The ultrathin flat plate speaker using double location support chips has the advantages of utilizing two novel location support chips and a flat plate sound basin with a bent ring, utilizing a structure of the location support chips and the flat plate sound basin, neglecting height of a cone-shaped sound basin and further optimizing the thickness of the speaker due to the vibration space which is arranged between the location support chips and the top of the magnetic path.
Description
Technical field
The present invention relates to the ultrathin flat panel loudspeaker of the two locating branch slices of a kind of use.
Background technology
Be used for now the high-power full frequency band loud speaker of the plate video equipments such as LCD, LED, PDP, generally all adopt internal magnetic circuit traditional type loadspeaker structure, formed by parts such as magnetic circuit, support, locating branch slice, sound basin and voice coil loudspeaker voice coils, locating branch slice and sound basin/ collision mutually of U iron top when guaranteeing the normal operation of loud speaker, cause product bad, need to be to the enough vibrations spaces of vibrational system.Although compare original outer-magnet speaker, due to reducing of magnetic circuit, reduced the thickness of whole loud speaker.
But due to structure, the especially structural limitations of sound basin and locating branch slice of the vibroseis of product, it is thinner that the whole loadspeaker structure that makes can't be optimized, and reaches simultaneously ability high-power, the requirement of low distortion.
Summary of the invention
The present invention seeks to provide for the defective that prior art exists the ultrathin flat panel loudspeaker of the two locating branch slices of a kind of use.
The present invention adopts following technical scheme for achieving the above object:
The present invention comprises basin frame and magnetic circuit with the ultrathin flat panel loudspeaker of two locating branch slices, and magnetic circuit is comprised of U iron, magnet steel and washer, is provided with two or 2 above magnetic circuits in the middle part of basin frame.
Respectively there is the locating branch slice of a semicircular in shape band boss at the two ends of described basin frame, and the semi-circle plane of locating branch slice is connected with support.
The platform plane of described locating branch slice projection and sound basin are dull and stereotyped to be connected, and the ring edge of sound basin is connected with basin top of the trellis edge, and the while top of voice coil loudspeaker voice coil is connected with the flat board of sound basin, makes whole voice coil suspension between the magnetic circuit gap.
Advantage of the present invention is to have adopted two novel locating branch slices and with the dull and stereotyped sound basin of ring, both structures have been utilized, omitted the height of taper sound basin, the vibrations space between locating branch slice and magnetic circuit top makes the thickness of loud speaker obtain further optimization.
Simultaneously:
1, owing to having adopted two semicircular locating branch slices of band convex flat platform that compliance is larger, effectively reduce the initial frequency of product, improved the low-frequency effects of loud speaker.
2, locating branch slice is arranged on basin frame two and brings in the structure that supports the sound basin, has guaranteed that the vibrational system of product is more stable when motion, has reduced the distortion that product is reset and is.Guaranteed again simultaneously powerful requirement.

Fig. 2 is the sectional structure chart of this invention loud speaker.
Number in the figure:
1 basin frame 2-2 ' locating branch slice
3-3 ' voice coil loudspeaker voice coil 4 sound basins
5-5 ' terminal block 6-6 ' washer
7-7 ' magnet steel 8-8 ' U iron
Embodiment
As depicted in figs. 1 and 2, according to design provided by the invention, be provided with two or n magnetic circuit in the middle part of basin frame, magnetic circuit is by U iron 8-8 ', magnet steel 7-7 ', washer 6-6 ' forms, and the structure of magnetic circuit system is identical with the magnetic circuit of traditional internal magnetic loudspeaker, voice coil loudspeaker voice coil is between the gap of washer and the formation of U iron, and magnetic circuit closely is connected with support.
The locating branch slice 2-2 ' that a semicircular in shape band boss is respectively arranged at the two ends of basin frame, the semi-circle plane of locating branch slice is connected with support, the platform plane of locating branch slice projection is connected with sound basin 4 is dull and stereotyped, the ring edge of sound basin is connected with basin frame 1 top, simultaneously the top of voice coil loudspeaker voice coil 3-3 ' is connected with the flat board of sound basin, makes whole voice coil suspension between the magnetic circuit gap.
Voice coil loudspeaker voice coil is with two lead-in wires, and lead-in wire one end is connected with the voice coil loudspeaker voice coil outer wall, and the other end is connected with terminal block 5-5 ' on being arranged on the basin frame.
Loud speaker can make the structure of whole product thinner, and acoustic performance and conventional loudspeakers are without obvious reduction, and product percent of pass is significantly improved, and therefore is specially adapted to the plate video equipments such as LCD, LED, PDP.
The above is only the preferred embodiments of the present invention, be not limited to the present invention, although with reference to previous embodiment, the present invention is had been described in detail, for a person skilled in the art, it still can be modified to the technical scheme that aforementioned each embodiment puts down in writing, and perhaps part technical characterictic wherein is equal to replacement.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
