Abstract
The utility model discloses an ultrathin and low-distortion loudspeaker and a sound box using the loudspeaker. The loudspeaker comprises a basin rack, a paper disc, an iron core, magnetic steel, a voice coil and a centering supporting sheet. The paper disc is fixed on an opening of the basin rack. The iron core is fixed inside the basin rack. The magnetic steel is positioned on the top part of the iron core. The top part of the magnetic steel is sleeved with the voice coil. The centering supporting sheet is fixed inside the basin rack. The bottom part of the centering supporting sheet is right opposite to the top part of the voice coil. The center of the centering supporting sheet is provided with a through hole. The periphery of the through hole is provided with multiple wave crests and wave troughs which are distributed on multiple closed arcs. The edge of the centering supporting sheet extends so that a supporting foot is formed. With the application of the aforementioned manner, the height of the centering supporting sheet is increased so that amplitude sound of pure tone detection is avoided, distortion and unfavorable cases are mitigated, thickness of the loudspeaker is lowered and tone quality performance of the sound box is enhanced.

In preferred embodiment of the utility model, described iron core is U-iron.
The utility model also provides a kind of audio amplifier, comprise described ultra-thin low-distortion loudspeaker, described ultra-thin low-distortion loudspeaker comprises the basin frame, paper disc, iron core, magnet steel, voice coil loudspeaker voice coil and centring disk, described paper disc is fixed on the opening part of described basin frame, described iron core is fixed on described basin frame inside, described iron core top is placed with magnet steel, described magnet steel top cover has voice coil loudspeaker voice coil, described centring disk is fixed on basin frame inside, described centring disk bottom is over against described voice coil loudspeaker voice coil top, described centring disk center is provided with through hole, a plurality of some crest and troughs on closed camber line that are distributed in are arranged around described through hole, the edge of described centring disk extends to form leg.
The beneficial effects of the utility model are: described centring disk is provided with leg, has increased the height of centring disk, avoids the amplitude sound of pure tone detection, has alleviated the distortion unfavorable condition, has improved the tonequality performance of audio amplifier; Described iron core is placed in basin frame inside, has reduced the thickness of loud speaker.
The accompanying drawing explanation
Fig. 1 is the profile of the utility model loud speaker one preferred embodiment.
In accompanying drawing, the mark of each parts is as follows: 1, basin frame; 2, paper disc; 3, iron core; 4, magnet steel; 5, voice coil loudspeaker voice coil; 6, centring disk.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection range of the present utility model is made to more explicit defining.
Refer to Fig. 1, the utility model embodiment comprises:
A kind of ultra-thin low-distortion loudspeaker, comprise basin frame 1, paper disc 2, iron core 3, magnet steel 4, voice coil loudspeaker voice coil 5 and centring disk 6, described paper disc 2 is fixed on the opening part of described basin frame 1, described iron core 3 is fixed on described basin frame 1 inside, the plane at place, described magnet bottom is identical with described basin frame 1 plane, place, bottom, described iron core 3 tops are placed with magnet steel 4, described magnet steel 4 top covers have voice coil loudspeaker voice coil 5, described centring disk 6 is fixed on basin frame 1 inside, described centring disk 6 bottoms are over against described voice coil loudspeaker voice coil 5 tops, described centring disk 6 centers are provided with through hole, a plurality of some crest and troughs on closed camber line that are distributed in are arranged around described through hole, the edge of described centring disk 6 extends to form leg.
Wherein, described paper disc 2 omits micro-pits to described centring disk 6 place directions, less than existing paper disc cup depth, helps to reduce the thickness of described loud speaker.Described leg extends to the direction away from described through hole center from the edge of described centring disk 6, and the plane at the bearing of trend of described leg and described closed camber line place forms an angle.The gross thickness of described centring disk 6 is 3-7mm, and in the present embodiment, the gross thickness of described centring disk 6 is 5mm.The gross thickness of described basin frame 1 is less than or equal to 1.6cm, and described iron core 3 is U-iron.
