The platform loudspeaker can provide the high sound quality in a narrow-long space, and the appearance size of the platform loudspeaker can be changed randomly in a large range.
Description
Technical field
The utility model relates to a kind of loud speaker, and in particular, the utility model is about a kind of panel speaker.
Background technology
At present, it is circular that traditional loud speaker mostly is, and consider sensitivity and LF-response, and its size is difficult for reducing.Loud speaker is relatively large at the amplitude of low-frequency range, in order to guarantee and reduce the generation of unusual sound and stablizing of characteristic that therefore when design, the ring and the centring disk that can take into account with vibrating basin come acting in conjunction to keep the stability of loud speaker.Yet because normally comparatively narrow type or the more slim design of plate speaker, the design of narrow type like this certainly will cause the use of the littler centring disk of size.And being limited to technology and material, the big compliance of less centring disk is difficult for obtaining, and under the large amplitude of low-frequency range, the limited stroke of centring disk will limit the vibration of voice coil loudspeaker voice coil, causes significantly pullling sound and bigger nonlinear distortion.When serious, can have influence on the stability of cell operation on the contrary.The space that centring disk is kept in former still more conventional loudspeakers unit also is difficult for more successfully establishing at this allows enforcement, and brings difficulty can for aspects such as production technology, quality management and control.
Patent Office of the People's Republic of China announced on November 29th, 2006) a CN2842951Y document, name is called panel speaker, this panel speaker comprises plane vibration plate, voice coil loudspeaker voice coil, basin frame, magnetic circuit system, magnetic circuit system places on the support, voice coil loudspeaker voice coil simultaneously is connected on the magnetic circuit system, another side is connected on the plane vibration plate, described plane vibration plate is divided into big young waiter in a wineshop or an inn's piece, the breach that band extends internally in the middle of the big plane vibration plate, the facet oscillating plate just covers on the breach of massive plate, and described voice coil loudspeaker voice coil passes the breach of big plane vibration plate and fixes.Though this panel speaker has the manufacture difficulty that has reduced existing panel speaker, operating efficiency and output have been improved, improved product quality, reduced the advantage of defect ware, but exist the bulk of loud speaker is had relatively high expectations, be difficult to satisfy the shortcoming that existing market requires the more and more harsher confined space of loud speaker.
The utility model content
The utility model has solved the problem that is difficult to obtain the high tone quality quality in the prior art in the confined space, and a kind of panel speaker is provided, and can obtain good tonequality quality in the narrow space scope.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of panel speaker, comprise magnetic circuit system, voice coil loudspeaker voice coil, basin frame, oscillating plate, ring, described magnetic circuit system comprises permanent magnet and is trapped among the magnetic conductor of permanent magnet outside, magnetic conductor and permanent magnet form a physics magnetic air gap, are marked with magnetic liquid in the magnetic air gap; Described voice coil loudspeaker voice coil is made up of speech coil framework and the voice coil line on speech coil framework, and an end of speech coil framework is in magnetic liquid, and the other end and the oscillating plate of speech coil framework are bonding; Magnetic circuit system is provided with the basin frame, and ring is fixed on the basin frame, and ring links to each other with oscillating plate.The centring disk of conventional loudspeakers unit is got rid of, and injected magnetic liquid in magnetic gap, this not only helps reducing the overall height of panel speaker unit, and can reduce the resonance frequency of panel speaker unit effectively.Thus, can effectively reduce the height of panel speaker, the low frequency of expanding panel speaker, the sensitivity that promotes panel speaker, level and smooth loud speaker frequency response curve, reduce loudspeaker unit distortion, keep the stability of loudspeaker unit under the large amplitude, and can reduce the space structure requirement of loud speaker greatly.
As preferably, described permanent magnet is cylindrical, and described magnetic conductor comprises magnetic conductor bowl and upper conduction magnetic board, and permanent magnet places between magnetic conductor bowl and the upper conduction magnetic board, has a physics magnetic air gap between magnetic conductor bowl and upper conduction magnetic board, is marked with magnetic liquid in this physics magnetic air gap.Permanent magnet can be designed to the cylindricality of different shape, permanent magnet be designed to cylindrical, and whole magnetic Circuit Design is conglobate, this not only convenient manufacturing also can obtain the better tone quality quality.
As preferably, described ring is arch shape.Usually the ring of panel speaker is racetrack or rectangle, in order to increase the stroke of voice coil loudspeaker voice coil, its ring is also standing counts high arch, and the height of arch sheet and broadband can change arbitrarily by the space that reality can provide, and therefore the size of loud speaker are changed with actual needs.
As preferably, described basin sets up and is equipped with the supporting construction that supports ring.Because the ring straight flange is long, than large amplitude the time, long limit can the weak phenomenon of easier appearance, causes abnormal conditions such as oscillating plate tilts, waves generation.Therefore, for anti-unsettled here situation takes place, the supporting construction of a support ring is set at the basin frame.
The beneficial effects of the utility model are: in long and narrow space, the panel speaker of high tone quality quality also can be provided, the overall dimension of loud speaker can change arbitrarily in the larger context, or do various distortion for the outer shape of magnetic circuit or be on a loudspeaker unit, to use several magnetic circuit systems according to performance requirement, this does not all influence application of the present utility model and can satisfy market size and the performance requirement more and more harsher to loud speaker.
