Abstract
An ultrathin ultrahigh-pitch plane belt-type loudspeaker belongs to the technical field of electroacoustics. A general plane belt-type loudspeaker has disadvantages of being complex in manufacturing process, large in structure size, and high in cost. The loudspeaker comprises a plastic outer shell, a plane belt-type diaphragm, and a magnetic circuit system. The magnetic circuit system comprises sound-absorbing cotton, sound-absorbing felt, neodymium iron boron magnetic steel, and a metal magnetic conducting plate. The plane belt-type diaphragm is a polyimide (PI) film printed with a line-shaped thin aluminum foil having a thickness of 0.005 mm to 0.025 mm. The plane belt-type diaphragm is directly mounted on the magnetic circuit system. The plane belt-type diaphragm and the magnetic circuit system are combined and then buckled into the plastic outer shell to form the ultrathin plane belt-type loudspeaker. The thickness of the plastic panel ranges from 8 mm to 12 mm. The ultrathin ultrahigh-pitch plane belt-type loudspeaker is simple in structure and easy to install; and the ultrathin ultrahigh-pitch plane belt-type loudspeaker adopts the parallel-type magnetic circuit system so that the loudspeaker is enabled to form a strong and uniform driving force and to extend the frequency to 40000 Hz; and the ultrathin ultrahigh-pitch plane belt-type loudspeaker is high in fidelity, small in distortion, and high in efficiency.
Description
Technical field
The utility model belongs to the electroacoustic techniques field, and especially to wear the formula loud speaker relevant with a kind of ultra-thin superelevation tone level.
Background technology
Along with popularizing of panel TV, more and more higher to the requirement of the thickness of loud speaker, conventional loudspeakers all belongs to the coil-moving speaker scope usually, though production technology is simple, and low cost.But from result of use, its poor sensitivity, especially in the easy distortion of high frequency range, the frequency of high pitch is narrow, and ear-piercing noise appears in regular meeting.The thickness of conventional loudspeakers also is more and more can not satisfy panel TV to the demand of high-fidelity tonequality.Although conventional ribbon speaker can perfect playback high frequency, and tone color and tonequality shows unique characteristics, and conventional plane ribbon speaker manufacturing process complexity, structural volume are big, and the factor that cost is high causes ribbon speaker to be difficult to promote the use.
The utility model content
The purpose of this utility model is exactly the weak point that will overcome above-mentioned plane ribbon speaker, provides a kind of simple in structure, easy for installation, and lower-cost ultra-thin superelevation tone level is worn the formula loud speaker.
For this reason, the utility model provides following technical scheme, a kind of ultra-thin superelevation tone level is worn the formula loud speaker, comprise plastic casing and be built in the interior magnetic circuit system of plastic casing, be provided with plane belt diaphragm between the panel of magnetic circuit system and plastic casing, it is characterized in that: described plane belt diaphragm is the thin aluminium foil that has printed the circuit shape on polyimides (PI) film, thin aluminum foil thickness is between 0.005mm ~ 0.025mm, plane belt diaphragm is fixed with fixed support, described magnetic circuit system comprises acoustical cotton, deadener felt, Nd-Fe-B magnet steel and metal magnetic conducting plate, Nd-Fe-B magnet steel is fixed on the metal magnetic conducting plate with glue, deadener felt is stuck in the gap of Nd-Fe-B magnet steel, and acoustical cotton lies in the Nd-Fe-B magnet steel top.
As the further of such scheme improved and replenish, the utility model also comprises following technical scheme:
Described plane belt diaphragm thickness is 0.3 ~ 0.02mm.
Described loud speaker integral thickness is 8mm ~ 12mm, and width is 18mm ~ 25mm, and length is 70mm ~ 90mm.
Described plane belt diaphragm one end is provided with the installation end as electric interface, is used for connecting the loud speaker splicing ear, and splicing ear connects by riveted.
Described metal magnetic conducting plate is concavo-convex, can play the intensity of strengthening magnetic conduction sheet on the one hand, can increase radiating effect on the other hand.
Described Nd-Fe-B magnet steel is strip, and magnetic circuit is for to arrange side by side by polarity S NS.
Described plastic casing bottom has the back-off structure design, elder generation lies in the plane belt diaphragm of the good splicing ear of riveted in the housing of plastic front board during installation, again magnetic circuit system is installed, need not fix by screw, at metal magnetic conducting backboard portion and plastic front board junction glue sealing.
The beneficial effects of the utility model are: the utility model provides a kind of simple in structure, and the ultra-thin superelevation tone level that the suitable panel TV that make simply, production cost is low or other acoustic product are used is worn the formula loud speaker.
Description of drawings
