Abstract
The utility model discloses a low-power and small-sized low-frequency loudspeaker. The low-power and small-sized low-frequency loudspeaker includes a cone frame, a cone of which the periphery is fixedly connected with a cone opening, a voice coil and a centring supporting sheet; a wire is wound on a cylindrical frame so that the voice coil can be formed; the centring supporting sheet is a snakelike supporting sheet; the snakelike supporting sheet comprises an outer ring fixedly connected with the cone frame, an inner ring which is fixedly connected with the voice coil, and a plurality of connection bars which connect the outer ring with the inner ring. According to the low-power and small-sized low-frequency loudspeaker of the utility model, the snakelike supporting sheet is adopted, and the weight and inertia effect of the supporting sheet can be reduced, and the low-frequency response effect of the loudspeaker can be enhanced, and therefore, the low-power and small-sized low-frequency loudspeaker can have excellent low-frequency output performance, and the lowest resonant frequency of the loudspeaker can achieve 70Hz. With the low-power and small-sized low-frequency loudspeaker adopted, auditory effects of products such as televisions can be effectively improved, and the quality of the products can be improved.
Description
Technical field
The utility model relates to loud speaker field, particularly a kind of small-power miniature, low frequency loud speaker.
Background technology
Loud speaker is a kind of very conventional electro-acoustic transducer device, Figure 1 shows that the basic structure schematic diagram of the coil-moving speaker of prior art.As shown in Figure 1, existing coil-moving speaker comprises taper basin frame 1, be fixedly installed the magnetic conductor bowl 3 of taper basin frame 1 bottom, be arranged on the magnet 2 of magnetic conductor bowl center, be arranged on the magnetic conductive board 4 at magnet 2 tops, the taper cone 5 that outer peripheral edges are fixedly connected with basin frame opening, described taper cone center is fixedly connected with cylindrical skeleton, on described cylindrical skeleton, be wound around and form voice coil loudspeaker voice coil 7 by a wire, also comprise outer end and the inner centring disk 6 that is fixedly connected with basin frame and cylindrical skeleton respectively and can spacing described cylindrical skeleton moves both vertically up and down simultaneously, wherein, between described magnetic conductive board and magnetic conductor bowl, form the uniform magnetic gap of a circle, the winding part of voice coil loudspeaker voice coil is symmetrical in magnetic gap and arranges.
When moving-coil speaker work, the wire of voice coil loudspeaker voice coil winding has electric current to pass through, and according to left hand rule, the winding in magnetic gap can produce the power conforming to direction with the current strength of flowing through and promote cone motion.Because centring disk and cone are movabilities on the direction of vibration of cone, but have very large rigidity in the direction vertical with direction of vibration, ensure voice coil loudspeaker voice coil winding part can be in magnetic gap proper motion and deflection does not occur.
But, existing loud speaker, especially small-sized low-power, as the loud speaker below 15W, its low-frequency effect is poor, can not meet existing demand to LF-response.
Utility model content
Technical purpose of the present utility model is the shortcoming that overcomes prior art, and the loud speaker that a kind of small-power is small-sized and low-frequency effect is good is provided.
For realizing above-mentioned technical purpose, the technical scheme that the utility model adopts is:
A kind of low-power miniature, low frequency loud speaker, comprise the cone that basin frame, outer peripheral edges are fixedly connected with basin frame opening, be wrapped in the voice coil loudspeaker voice coil and the centring disk that on cylindrical skeleton, form by a wire, described centring disk is snakelike sheet, snakelike described sheet comprises the outer shroud being fixedly connected with basin frame, the interior ring being fixedly connected with described voice coil loudspeaker voice coil, and connect described outer shroud and the multiple intercell connectors of interior ring.
Described intercell connector is 4-6 bar.
The ring of described cone is quality of rubber materials.
With respect to prior art, the beneficial effects of the utility model:
Loud speaker of the present utility model adopts snakelike sheet, has reduced weight and the inertia effects of a sheet, has strengthened its LF-response effect, there is good low frequency output performance, lowest resonant frequency reaches 70Hz, can effectively improve the auditory effect of television set etc., improves product quality.
Brief description of the drawings
Figure 1 shows that the basic structure schematic diagram of the coil-moving speaker of prior art;
Figure 2 shows that the sheet-supporting structure schematic diagram of loud speaker of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Loadspeaker structure of the present utility model similarly to the prior art, do not repeat them here, the distinctive points of itself and prior art maximum is, as shown in Figure 2, described centring disk is snakelike sheet, and snakelike described sheet comprises the outer shroud 11 being fixedly connected with basin frame, the interior ring 13 being fixedly connected with described voice coil loudspeaker voice coil, and connecting described outer shroud and the multiple intercell connectors 2 of interior ring, described outer shroud and interior ring are concentric ring.Preferably, described intercell connector is 4-6 bar.Wherein, snakelike described sheet is plastic material, as PEI(Polyetherimide).
Wherein, described intercell connector arranges in pairs and every pair of intercell connector is curved shape, the bending of every pair of intercell connector axisymmetricly formula design improves overall stationarity, wherein, described Curved intercell connector is preferably three stage structure, outer section 123 that outer end is fixedly connected with outer shroud is tilting section, general and this place radially keeps 40-60 degree angle, interlude 122 is the arc section concentric with described outer shroud, inner segment 121 is for radially extending and being fixedly connected with inner ring, two ends and interior ring and outer shroud junction also increase connection area simultaneously, to improve resistance to overturning, arc transition between each section, and entirety is integral type structure.
Loud speaker of the present utility model adopts snakelike sheet, has reduced weight and the inertia effects of a sheet, has strengthened its LF-response effect, there is good low frequency output performance, lowest resonant frequency reaches 70Hz, can effectively improve the auditory effect of television set etc., improves product quality.
Further, the ring of described cone is quality of rubber materials.The ring of existing PU material is replaced with to softer quality of rubber materials, can further show its low frequency performance.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
