Abstract

The utility model relates to a thin type woofer provided with a foam ring. The woofer is characterized in that a vibrating diaphragm is a flat plate; the ring is a circular ring made of foam materiel, and the cross section thereof is rectangular; two thin sheets are arranged on two sides of the rectangular surface; and the ring is respectively fixed with the frame of the woofer and the flat plate. the elasticity of the vibration part of the ring is wholly controlled by the characteristics of the material, so that the elastic recovery strength is uniform; the scale of the vibration range can be adjusted by the width of the non-pressed part of the ring, so that the better replay effect is achieved; and in the structure, the space for a branch piece is reduced, so that under the condition that the radiating surface of the woofer is unchanged, the height is reduced considerably, and the entire size is 83*83*83mm. The thin type woofer provided with a foam ring is particularly suitable for thin type woofers, can be widely applied to thin type color TVs and thin type sound boxes such as LCDs, PDPs and the like, and has wide market prospect.

Description

A kind of slim woofer with foam ring

Technical field

The utility model relates to a kind of loud speaker, particularly a kind of slim woofer with foam ring.

Background technology

Slim TV machines such as current LCD, PDP are as the main flow household products, the user progressively improves requiring on its outward appearance and the function, screen of TV set is increasing, and the thickness of complete machine is more and more thinner, so corresponding required loud speaker height also will reduce, and has been the challenge to the conventional loudspeakers structural design.

The displacement of paper awl swept area and vibration has direct relation in the size of well-known sound and the loud speaker, the strength that the paper awl promotes air is big more, the sound that we hear is also just big more, materials such as the cloth that existing woofer ring adopts mostly, foam, rubber, PU, be processed into certain radian, utilize of the use of the suppleness of the size of this radian and material as ring, and need to cooperate centring disk to guarantee that voice coil loudspeaker voice coil does piston moving stability and perpendicularity in magnetic gap, with 3 cun woofers is example, highly is about 45mm generally.

So will change its height to existing woofer, reach certain bass effect again, with regard to thick, heavy, the wide present situation of the traditional loudspeaker design of Gonna breakthrough, from the structure of new solution existing product, the design of vibrational system.

Summary of the invention

Problem in view of the prior art existence, the utility model provides a kind of vibrating diaphragm has been defined as flat board, and reduced by a shared height of vibrating mass one centring disk, in the ring design, the employing foamed material is hot pressed into rectangle and has the ring body of two featheredges, utilizes the expansion performance of material own to satisfy the slim woofer with foam ring of vibrational system amplitude needs.

The technical scheme that the utility model is taked for achieving the above object is: a kind of slim woofer with foam ring, comprise speaker frame, ring and vibrating diaphragm, it is characterized in that, described vibrating diaphragm is dull and stereotyped, described ring is the ring body shape ring of foamed material, its cross section is rectangular, and two thin slices are arranged in the rectangular surfaces both sides, and ring fixes with speaker frame and flat board respectively.

The beneficial effects of the utility model are: 1, all by the Characteristics Control of material itself, resilience strength is even for the elasticity of ring oscillating component, and the size of Oscillation Amplitude can have the audio fruit of resetting preferably by the ring width adjusting of press portion not.2, reduced the space of a sheet in the structure, under the constant condition of loud speaker swept area, reducing highly significantly, overall dimensions is 83 * 83 * 18mm.Being best suited for thin speaker uses.3, the utility model extensively model be used for slim colour TV and slim audio amplifiers such as LCD, PDP, the market prospects of wide model are arranged.

This method also can be used on other self resilient material, and the thickness of material and width need come adjusted design with coefficient of elasticity of material own and the required amplitude of vibrational system.

Embodiment

As shown in Figure 1, 2, a kind of slim woofer with foam ring, comprise speaker frame 1, ring and vibrating diaphragm, vibrating diaphragm is dull and stereotyped 3, ring is the ring body shape ring 2 of foamed material, and its cross section is rectangular 201, goes out two thin slices 202 in the hot pressing of rectangular surfaces both sides, ring 2 is supporting with speaker frame 1 and dull and stereotyped 3 shapes, can be made into circle, ellipse, rectangle, square, polygon or triangle.Dull and stereotyped 3 are made by plank or cellular board.

Patch bay group

8 and 1 riveted joint of basin frame, magnetic conductor bowl 4 is formed basin frame magnetic conductor bowl group with 1 riveted joint of basin frame, fall magnetic sheet 6 and magnet 5 bonding composition magnet groups, the magnet group sticks with glue knot in magnetic conductor bowl 4, ring 2 sticks with glue with speaker frame 1 and dull and stereotyped 3 respectively and connects, one end of voice coil loudspeaker voice coil 7 is bonding with dull and stereotyped 3, after magnet group in the magnetic conductor bowl 4 in the basin frame 1 magnetized, squeeze into magnetic liquid and guarantee voice coil loudspeaker voice coil correct position when vibration in the magnetic slit, voice coil loudspeaker voice coil 7 other ends are put into the magnetic slit simultaneously, because the effect of the magnetic line of force, voice coil loudspeaker voice coil 7 automatic capturings are in the center in magnetic slit, voice coil loudspeaker voice coil 7 adopts this line lead-out mode, and big lead-in wire is fixed on the speech coil framework, big lead-in wire and patch bay bond pads.
