Abstract
The utility model relates to an ultra-thin loudspeaker system, which comprises a box body and a loudspeaker body arranged in the box body. The loudspeaker body comprises a vibrating diaphragm, a magnetic conductive washer, a magnet, a coil and an elastic wave tray, wherein the elastic wave tray is made of a magnetic conductive metal plate, the middle part of the elastic wave tray is depressed, and a groove and a convex ring are arranged at the depressed position. The magnet is fixed in the groove, and the magnetic conductive washer is arranged above the magnet. The vibrating diaphragm is covered onto a port at the depressed position of the elastic wave tray, and the middle part of the vibrating diaphragm is connected with the magnetic conductive washer. The coil is sleeved on the magnetic conductive washer. The elastic wave tray, the magnet and the magnetic conductive washer form a magnetic circuit. The elastic wave tray is made of the magnetic conductive metal plate, and replaces the traditional magnetic conductive yoke to perform magnetic conduction, thereby reducing the thickness of the loudspeaker box body. Without the tightness of the traditional magnetic conductive yoke, the heat generated when the coil is heated can be directly transferred to the periphery of the system by convection, so that the handling power of the loudspeaker is somewhat improved.
Description
Technical field
The utility model belongs to a kind of speaker system, refers to the relatively more easy super-thin speaker system of a kind of magnetic loop structure especially.
Background technology
LCD in the market and LCD TV are all to more and more thinner trend development.But the speaker system that existing LCD and LCD TV are used is traditional magnetic loop form owing to what it adopted, because the structure of this magnetic loop is complicated, causes casing thickness always to be difficult to do thin.The speaker system of thick casing can not adapt to existing market and consumer demand, and those thick and heavy TVs and display device product will be eliminated and abandon by market in the past.So the speaker system of slim casing will become following dominant force person and commander person in the production development of LCD and LCD TV.
The utility model content
At the deficiency that above technology exists, the utility model provides a kind of magnetic loop structure relatively more easy super-thin speaker system, is difficult to do thin problem in order to the speaker system that solves LCD or LCD TV.
The technical scheme that the utility model is taked is as follows:
A kind of super-thin speaker system comprises casing and places loud speaker main body in the casing.The loud speaker main body comprises vibrating diaphragm, magnetic conduction washer sheet, magnet, coil and bullet ripple pallet.Wherein, playing the ripple pallet is a magnetic conductive metal sheet, its medial recess, and recess is provided with groove and bulge loop.Magnet is fixed in the groove, and magnetic conduction washer sheet then places the magnet top.Vibrating diaphragm covers on the port that plays ripple pallet recess, and its middle part links together with magnetic conduction washer sheet.Coil then is set on the magnetic conduction washer sheet.
Play ripple pallet, magnet and magnetic conduction washer sheet and constitute a magnetic loop.
The beneficial effects of the utility model are: utilize magnetic conductive metal sheet to make and play the ripple pallet, carry out the magnetic conduction by playing the alternative traditional conductive magnetic yoke of ripple pallet, make loudspeaker unit whole height drop by half, reduced the thickness of sound box thus.Because do not had the seal of traditional conductive magnetic yoke, the heat during coil heating can directly be sent to system peripherals by convection type, is discharged to outside the casing via paraphase airduct hole, makes the power that bears of speaker system obtain certain lifting.By simplifying raw material Master Cost and processing cost are reduced, thereby realized the decline of price.
Description of drawings
Fig. 1 is a cutaway view of the present utility model;
Fig. 2 is the local enlarged diagram of Fig. 1;
Fig. 3 is a front view of the present utility model;
Fig. 4 is a rearview of the present utility model.
Among the figure:
10 casings, 20 vibrating diaphragms,
30 coils, 40 magnetic conduction washer sheets,
50 magnet, 60 play the ripple pallet,
601 bulge loops, 602 grooves.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described:
Cutaway view of the present utility model as shown in Figures 1 and 2, the super-thin speaker system among the figure comprises casing 10 and the main body of raising one's voice that places in the casing 10.The main body of raising one's voice comprises vibrating diaphragm 20, magnetic conduction washer sheet 40, magnet 50, coil 30 and plays ripple pallet 60.Wherein, playing ripple pallet 60 is a magnetic conductive metal sheet, its medial recess, and recess is provided with groove 602 and bulge loop 601.Magnet 50 is fixed in the groove 602, and 601 of bulge loops are looped around around the magnet 50, thereby forms a groove between magnet 50 and bulge loop 601.Magnetic conduction washer sheet 40 places magnet 50 tops.Vibrating diaphragm 20 covers on the port that plays ripple pallet 60 recess, and its middle part links together with magnetic conduction washer sheet 40.30 of coils are set on the magnetic conduction washer sheet 40.Play ripple pallet 60, magnet 50 and magnetic conduction washer sheet 40 and constitute a magnetic loop.The apparent condition of the loud speaker that is combined into such as Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4.During work, flow into the magnetic field that the alternating current of coil 30 changes coil 30, the magnetic field interaction of this magnetic field and magnet 50 self makes coil 30 be subjected to different magnetic force, thus generation vibration in various degree.The vibration of coil 30 can drive connected magnetic conduction washer sheet 40 and vibrate together, and then drives vibrating diaphragm 20 and vibrate together, and loud speaker is then by vibrating diaphragm 20 vibration soundings.
Certainly, above embodiment just is explanation rather than restriction the utility model, the above only is preferred embodiment of the present utility model, so all equivalences of being done according to the described method of the utility model patent claim change or modify, is included in the utility model patent claim.
