Abstract
The utility model relates to a planar loudspeaker with high-fidelity sound effect, which comprises a magnetic circuit system, a voice coil, a plate diaphragm and a speakerframe, wherein, the two ends of the voice coil are respectively connected with the magnetic circuit system and the plate diaphragm. The planar loudspeaker is characterized in that: an elastic support device is arranged between the plate diaphragm and the speakerframe; and the elastic support device plays roles of supporting and enforcing position to the plate diaphragm, which leads the plate diaphragm to have comparatively good stability, and the voice coil is not easy to be rubbed, therefore, the planar has better sound effect fidelity compared with the existing technology.

The utility model content
The utility model mainly is to solve existing in prior technology easy sassafras circle and because vibrational system motion non-linear causes the technical problem of distortion etc. when high-power, provide a kind of and between plate diaphragm and basin frame, be provided with resilient supporting unit, make panel speaker also be difficult for the sassafras circle when more high-power having, and have the panel speaker of high-fidelity audio simultaneously.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of panel speaker of high-fidelity, comprise magnetic circuit system, voice coil loudspeaker voice coil, plate diaphragm and basin frame, the two ends of described voice coil loudspeaker voice coil join with magnetic circuit system and plate diaphragm respectively, it is characterized in that: be provided with resilient supporting unit between described plate diaphragm and the basin frame.By between plate diaphragm and basin frame, being provided with resilient supporting unit, resilient supporting unit plays the effect of supporting and adding strong fix to plate diaphragm, make the vibration of plate diaphragm have stability preferably, voice coil loudspeaker voice coil also is difficult for the sassafras circle when high-power, thereby the utility model has better audio fidelity performance compared to existing technology.
As preferably, described resilient supporting unit is located on the bottom surface of basin frame.Resilient supporting unit is located at the support that helps on the bottom surface of basin frame plate diaphragm.
As preferably, described resilient supporting unit is vertical setting with plate diaphragm.Resilient supporting unit and plate diaphragm are to be vertically installed with the stability that is beneficial to the plate diaphragm vibration.
As preferably, described resilient supporting unit is provided with 2 at least, and all resilient supporting units to be located at the plate diaphragm center equably be on the annulus in the center of circle.Described resilient supporting unit can be spring or spring leaf, also can be some rubber-like springs, resilient supporting unit is provided with 2 at least, all resilient supporting units are located on the same circular arc equably, for example, if resilient supporting unit is provided with 3, then 3 resilient supporting units are the equilateral triangle distribution, and with the plate diaphragm center is the center of circle, make the vibration of plate diaphragm have stability preferably, certainly, resilient supporting unit also can be that the elastic ring of a ring-type becomes the concentric setting with plate diaphragm, can make equally to the utlity model has audio fidelity performance preferably.
As preferably, the center of described plate diaphragm offers the voice coil loudspeaker voice coil seat, and voice coil loudspeaker voice coil is inserted in the voice coil loudspeaker voice coil seat.The center of plate diaphragm offers the voice coil loudspeaker voice coil seat, voice coil loudspeaker voice coil is inserted in the voice coil loudspeaker voice coil seat, utilize the inhibitory action of cutting apart vibration of voice coil loudspeaker voice coil to plate diaphragm, make the utility model can obtain comparatively smooth frequency response curve in use, thereby has a fidelity preferably, voice coil loudspeaker voice coil is inserted in the voice coil loudspeaker voice coil seat, has also changed the bonding complicated technology of traditional voice coil loudspeaker voice coil and plate diaphragm, manufactures more simple.
As preferably, described voice coil loudspeaker voice coil seat is a through hole.The voice coil loudspeaker voice coil seat is a through hole, and voice coil loudspeaker voice coil interts at through hole, and voice coil loudspeaker voice coil is better to the inhibition effect of cutting apart vibration of plate diaphragm.
As preferably, described voice coil loudspeaker voice coil seat is a groove.Certainly, the voice coil loudspeaker voice coil seat adopts groove, also has the same effect of through hole.
As preferably, the top of described voice coil loudspeaker voice coil is provided with dust cap.The setting of dust cap can prevent that dust from entering from the top of voice coil loudspeaker voice coil, influences loud speaker tonequality.
Therefore, the utlity model has following characteristics: 1. simple in structure, reasonable in design; 2. be provided with resilient supporting unit between plate diaphragm and basin frame, make the vibration of plate diaphragm have stability preferably, voice coil loudspeaker voice coil also is difficult for the sassafras circle when high-power; 3. voice coil loudspeaker voice coil is inserted in the voice coil loudspeaker voice coil seat, utilizes the inhibitory action of cutting apart vibration of voice coil loudspeaker voice coil to plate diaphragm, has fidelity preferably; 4. voice coil loudspeaker voice coil is inserted in the voice coil loudspeaker voice coil seat, has also changed the bonding complicated technology of traditional voice coil loudspeaker voice coil and plate diaphragm, manufactures more simple.
