Description

A kind of loudspeaker unit

Technical field

The utility model relates to a kind of loudspeaker unit, particularly relates to one and has the annular loudspeaker unit of special folding.

Background technology

The movement of vibrating diaphragm is not only supported and kept to ring (Edge), as the indispensable part of the diaphragm of loudspeaker, makes vibrating diaphragm can in axial direction free vibration, but can not transverse shifting, also ensures that voice coil loudspeaker voice coil also can move axially in magnetic gap simultaneously.The shape of ring has multiple, and that commonly uses at present has corrugated ring and semicircle ring type ring.Be illustrated in figure 1 corrugated ring, its form has some ripples, and the flexible of this ring has certain limit, and when amplitude, the displacement of circumferencial direction is locked, thus linearly bad.As shown in Figures 2 and 3, normally by the semicircle ring type ring of Foamex, rubber type of material hot briquetting, epirelief ring (Fig. 2) and recessed ring (Fig. 3) can be divided into according to the direction difference of ledge.Compare with wave ring, semicircle ring type ring allows comparatively large amplitude.But linear in order to what ensure under large amplitude, the width of ring will strengthen, and thus radius of curvature is also large, causes ring intensity to decline.

Utility model content

In order to solve the problem, the utility model proposes a kind of loudspeaker unit, comprising: frame, be rigidly connected on sound box; Magnetic circuit system, is mounted in described frame, for providing voice coil loudspeaker voice coil magnetic field; Voice coil loudspeaker voice coil, is placed in the magnetic gap of described magnetic circuit system, and can vibrate according to magnetic force change; Vibrating diaphragm, its peripheral end is engaged with described frame by a suspension, and its inner peripheral end thereof is engaged with described voice coil loudspeaker voice coil by centring disk; Described suspension is the elastic component of longitudinal extension, connects described vibrating diaphragm and described frame.

Especially, described suspension is the snake abdomen shape of hollow or corrugated or fold-line-shaped or arc.

Especially, described suspension comprises the first extensible member and the second extensible member, and described first extensible member top engages with described frame, and described first extensible member bottom engages with described vibrating diaphragm, described second extensible member top engages with described vibrating diaphragm, and described second vibrating diaphragm bottom engages with described frame.

The suspension of the utility model loudspeaker unit can make vibrating diaphragm have larger displacement in the axial direction, and it is linearly better, effective vibration area of loudspeaker unit can be increased simultaneously, thus more small-bore loud speaker can be used reach the effect of more heavy caliber loudspeaker unit.When sound box constancy of volume, compared to prior art, the size of the utility model loudspeaker unit can realize junior unit high sound pressure, promotes audio amplifier audio.

Other features and advantages of the utility model will be set forth in the following description, and, partly become apparent from specification, or understand by implementing the utility model.The purpose of this utility model and other advantages realize by structure specifically noted in write specification, claims and accompanying drawing and obtain.

Introduce preferred embodiment below in conjunction with accompanying drawing, the technical scheme that the utility model proposes is described in detail.It should be noted that, the object of accompanying drawing is just convenient to the explanation to the utility model specific embodiment, is not a kind of unnecessary describing or the restriction to the utility model scope.

Embodiment

Embodiment one

Be illustrated in figure 4 the structural representation of the loudspeaker unit of the present embodiment.Frame 01 is made up of rigid material, supports whole loudspeaker unit, and is rigidly connected on sound box.Magnetic circuit system 06 is combined by train wheel bridge 61, magnet 62 and magnetic conductor (T iron) 63 and is bonded and form.Cylindric magnetic gap 64 is formed between the medial surface and magnetic conductor 63 of train wheel bridge 61.This magnetic circuit system 06 is arranged in frame 01, for the voice coil loudspeaker voice coil 05 of loudspeaker unit provides magnetic field.Voice coil loudspeaker voice coil 05 is configured in the magnetic gap of magnetic circuit 06, vibrates according to magnetic force change.As the vibrating diaphragm 02 of speaker vibration system major part, its peripheral end is engaged with frame 01 by suspension 03, and its inner circumferential end is connected with voice coil loudspeaker voice coil 05 by centring disk 04.Vibrating diaphragm 02 is usually knitted product, staple fibre, chemical fibre, rubber type of material or metallic film made by paper, resin, various tiffany.

Suspension 03 is corrugated elastic component, can longitudinal extension.But being not limited thereto shape, also can be other shapes, as: snake abdomen shape, fold-line-shaped or arc, as long as suspension 03 longitudinal extension can be made.As shown in Figure 5, suspension 03 is the convex arc elastic part to vibrating diaphragm inner circumferential.

Embodiment two

The present embodiment has and the magnetic circuit system of embodiment one same structure, voice coil loudspeaker voice coil and vibrating diaphragm, but suspension is different.Be illustrated in figure 6 the suspension schematic diagram that the present embodiment loudspeaker unit adopts.Suspension comprises the first extensible member 31 and the second extensible member 32.Top and the frame 01 of the first extensible member 31 are glued together, bottom and vibrating diaphragm 02 glued together; Top and the vibrating diaphragm 02 of the second extensible member 32 are glued together, bottom and frame 01 glued together.

The shape of the first extensible member 31 and the second extensible member 32 is corrugated, but is not limited to corrugated, also can be other shapes, as snake abdomen shape, fold-line-shaped or arc, as long as can make the first extensible member 31 and the second extensible member 32 can longitudinal extension.

The suspension of embodiment one and embodiment two can make vibrating diaphragm have larger displacement in the axial direction, and it is linearly better, effective vibration area of loudspeaker unit can be increased simultaneously, thus more small-bore loud speaker can be used reach the effect of more heavy caliber loudspeaker unit.In other words when sound box constancy of volume, compared to prior art, the size of above embodiment loudspeaker unit can realize junior unit high sound pressure, promotes audio amplifier audio.

The above is only preferred implementation of the present utility model; but the limitation that they are not the utility model scopes should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model principle, done some improvements and modifications also should be considered as within protection range of the present utility model.
