Abstract
The utility model relates to a loudspeaker with bias force vibration diaphragm, which belongs to the sound producing device. Under the state of not exerted by bias force, the vibration diaphragm of the existing speaker is arranged on a speaker and generates various distortion mostly to make the effect of sound quality unideal. The utility model aims at providing a loudspeaker with bias force vibration diaphragm, wherein, the vibration diaphragm is additionally provided with an elastic element, so the vibration diaphragm is added with elastic static force and a loudspeaker has the advantages of no distortion, flat frequency response, high boost and ideal sound quality effect. The utility model has the advantages of simple structure and easy application, and is easy to popularize and apply.
Description
The utility model belongs to microphone device.
Vibrating membrane itself in the loud speaker all is installed in the loud speaker under non-quiet bias force state at present.Vibrating membrane has paper, plastics, metal or composite material, be contained in after making in the loud speaker, the vibrating membrane face was not to be subjected to any external force when loud speaker was not worked, and promoted air by the vibrating membrane conduction vibration during speaker operation and sounded, but mostly produce various distortions, acoustical quality is undesirable.
The purpose of this utility model provide a kind of on vibrating membrane in addition the elasticity static(al) have a loud speaker that is subjected to the bias force vibrating membrane, avoid the generation of various distortions, make the frequency response of loudspeaker smooth, high boost, acoustical quality is better.
The technical solution of the utility model is the structure that does not change existing loud speaker, it is characterized in that the vibrating membrane that this loud speaker uses is to be subjected to the bias force vibrating membrane, promptly glue between vibrating membrane inner edge and vibrating membrane outer rim several elastic components are housed, elastic component makes vibrating membrane be subjected to be operated in the loud speaker behind the bias force.
This elastic component can be contained in the inner surface or the outer surface of vibrating membrane face, and the power that elastic component produced can be pressure or pulling force.
The utility model enforcement simple in structure, easy has improved the acoustical quality of loud speaker effectively.
Accompanying drawing is the structural representation of a kind of embodiment of the utility model.Fig. 1 is the structural representation with the loud speaker that is subjected to the bias force vibrating membrane, and Fig. 2 is the schematic diagram that is subjected to the bias force vibrating membrane.Among the figure: 1 vibrating membrane, 2 basin framves, 3 upper guide plates, 4 bottom guides, 5 voice coil loudspeaker voice coils, 6 magnet steel, 7 locating branch slices, 8 elastic components, 9 dust covers, 10 vibrating membrane inner edges, 11 vibrating membrane outer rims, 12 vibrating membranes neck ring.
Below in conjunction with accompanying drawing the utility model is further described.
The overall structure of this loud speaker is identical with existing loud speaker, is characterized in sticking between the vibrating membrane inner edge (10) of vibrating membrane (1) and vibrating membrane outer rim (11) several elastic components (8) are housed, and elastic component makes vibrating membrane be subjected to be operated in the loud speaker behind the bias force.
Elastic component is the shell fragment of being made by certain width rubber-like material in the present embodiment, makes sharp zigzag at the two ends of shell fragment.During installation, make shell fragment slightly behind the tool elastic force, along the vibrating membrane radial direction, utilize sawtooth one end at shell fragment two ends to be stuck near the vibrating membrane inner edge, the other end is stuck near the vibrating membrane outer rim, and it is fixing to be glued afterwards.At this moment, because the effect of shell fragment makes vibrating membrane be in outside tension force (pulling force) state.
The utility model is simple in structure, implements need not change the structure of existing loud speaker easily.Can after finishing, the loud speaker manufacture craft install shell fragment again additional; Also can make vibrating membrane (being subjected to the bias force vibrating membrane) earlier as shown in Figure 2, will be subjected to bias force vibrating membrane dress afterwards again in loud speaker with shell fragment.
This effect that is subjected to elastic component in the bias force vibrating membrane has been equivalent to improve the rigidity of vibrating membrane face, has strengthened the intermolecular damping of inside diaphragm again simultaneously, has eliminated that face in the existing vibrating membrane work is cut apart vibration and the various harmful effects that cause.This practice is applicable to the vibrating membrane of various materials, elastic component is given vibrating membrane in addition elastic pressure or pulling force, make the molecule in the vibrating membrane work in elasticity (pressure or pulling force) district, simultaneously the active force from voice coil loudspeaker voice coil (5) of vibrating membrane inner edge can be passed to the vibrating membrane outer rim rapidly, make the vibration work with various frequency signals simultaneously of whole face.
Elastic component also can be fixed on the outer surface of vibrating membrane as shown in phantom in Figure 1.The number of elastic component is generally more than three.
Elastic component can be used the elastomeric material of rubber band one class instead and make, and is fixed on the vibrating membrane after rubber band is slightly elongated, and formation can produce the elastic component of pulling force.
Parameters such as the material of elastic component, shape, dimensions, according to the diaphragm diameter size, factors such as the thickness of face are determined.
The present utility model people has implemented various middle pitches, bass has the loud speaker that is subjected to the bias force vibrating membrane and all obtains highly desirable acoustical quality.Especially the woofer of some material is made the 5 inch/10w of vibrating membrane as cone, 6.5 inch/30w, and 8 inch/10w, the loud speaker of 10 inch/10w has all become undistorted, the very pure wide-band loudspeaker clearly of tonequality that frequency response is smooth.Rated power playback effect unanimity from the small volume to the loud speaker.
Claims (1)
1, has the loud speaker that is subjected to the bias force vibrating membrane, structure by existing loud speaker is formed, the vibrating membrane that it is characterized in that using in the loud speaker is for being subjected to the bias force vibrating membrane, promptly between vibrating membrane inner edge and vibrating membrane outer rim elastic component is housed, elastic component makes vibrating membrane be subjected to be operated in the loud speaker behind the bias force.
