Abstract
The utility model discloses a loudspeaker, which comprises a magnetic loop, a vibration system and a supporting system, wherein the magnetic loop comprises magnetic steel (5), a claming plate (7) and a T-shaped iron (8); the vibration system comprises an elastic wave (3), a voice coil (2) and a sound cone (6); and the supporting system comprises a cone frame (1) and a protective hood (9). The loudspeaker further comprises a liner plate (10); the center hole of the liner plate (10) is tightly matched with the outer side wall of the clamping plate (7); the elastic wave (3) is provided with an annular flat bottom groove (11); and the outer bottom of the annular flat bottom groove (11) is fixedly connected with the liner plate (10). The loudspeaker can reduce the axial movement of the elastic wave body so as to reduce the distortion of sound.
Description
Technical field
The utility model relates to electro-acoustic transducer device, specifically is a kind of loud speaker.
Background technology
Loud speaker comprises magnetism loop, vibrational system and support system, and described magnetism loop comprises that magnet steel, T iron, clamping plate are magnetic conductive board; Described vibrational system involving vibrations plate is sound basin, voice coil loudspeaker voice coil and is installed in bullet ripple on the loud speaker body main shaft that described support system comprises basin frame, protective cover.The groundwork principle of loud speaker is that loud speaker is changed the signal of telecommunication of input, leans on the vibrations of the bullet ripple of loud speaker to sound.The loudspeaker play-wave of prior art comprises that section is wavy and has the bullet ripple body of centre bore and be installed in the power supply input lead that plays on the ripple body.Described bullet ripple body and clamping plate top are binded fixing, because it is comparatively violent to play the vibration of ripple body, plays the ripple body axial motion easily takes place, and will cause the audio distortions of loud speaker like this, even can not send out sound, influence the useful life of loud speaker.
The utility model content
The technical problems to be solved in the utility model is, overcomes the defective of above prior art, provides a kind of can the minimizing to play the loud speaker that the axial motion of ripple body reduces audio distortions.
Technical solution of the present utility model is, a kind of loud speaker with following structure is provided: it comprises magnetism loop, vibrational system, support system, described magnetism loop comprises magnet steel, clamping plate and T iron, described vibrational system comprises bullet ripple, voice coil loudspeaker voice coil and sound basin, described support system comprises basin frame and protective cover, it also comprises a backing plate, the lateral wall tight fit of the centre bore of described backing plate and clamping plate, described bullet ripple is provided with an annular flat bottomed recess, and the outer bottom of described annular flat bottomed recess is fixedlyed connected with backing plate.
After adopting above structure, a kind of loud speaker of the utility model compared with prior art, have the following advantages: on the bullet ripple, be provided with an annular flat bottomed recess, fixedly connected with backing plate in the bottom of described groove, so just make the bullet ripple connect more stable, reduce moving axially of bullet ripple in bullet ripple oscillatory type, thereby reduced the audio distortions of loud speaker.
As a kind of improvement, the bottom of described protective cover is provided with a ring support that matches with annular flat bottomed recess, and the outer bottom of described ring support is pressed on the interior diapire of annular flat bottomed recess.Vibrate when violent playing ripple like this, this ring support has further limited again and has played moving axially of ripple.
