Description
Technical field
The present invention relates to a kind of loud speaker.
Background technology
As everyone knows, sound equipment is arranged on by the loud speaker (being also referred to as unit or transducer) of different size that casing (box) through design is inner to be formed.Two roads that the sound system of complete set is normally made up of different loud speakers (unit) such as high pitch, middle pitch, basses or three road dividing networks are formed.Namely a sound equipment be made up of high pitch loudspeaker and woofer belongs to two road frequency division systems; Namely a sound equipment be made up of high pitch loudspeaker, Squawker and woofer belongs to three road frequency division systems.Visible, no matter which kind of sound system, all be unable to do without loud speaker, particularly high pitch loudspeaker.
In prior art, modal is ball top high pitch loud speaker, and its acoustic radiation is point sound source and spherical wave, there is following shortcoming:
1, vibrating diaphragm area is less.
2, radiation efficiency is lower.
3, easily phase distortion and linear modulation distortion is produced.
4, the burden caused to power amplification system is large.
Separately have a kind of belt and the pneumatic high pitch loudspeaker of belt, although be better than ball top high pitch loud speaker in some aspects, though its vibrating diaphragm area is greater than ball top high pitch loud speaker, vibrating diaphragm is all planar structure, there is following shortcoming:
1, radiating acoustic energy is uneven, sound field is narrow, diffusion angle is broad not.
2, little in the acoustic density of treble, full not, propagate diameter shorter.
3, narrow in Hz-KHz (range).
4, power and sound pressure level (loudness rank) lower.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of area much larger than ball top high pitch loud speaker, radiating acoustic energy be even, sound field is wide, diffusion angle is broad, propagate that diameter is large, large in the acoustic density of treble, Hz-KHz is wide, sensitivity and the high vibrating diaphragm of efficiency and adopt the aerodynamic energy loud speaker of this vibrating diaphragm.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of arc vibrating diaphragm, this vibrating diaphragm is provided with circuit, and the cross section after this vibrating diaphragm is shaping is arc.
Cross section after described vibrating diaphragm is shaping is semi-cylindrical.
Described vibrating diaphragm is provided with the sinusoidal wave shape fold arranged along its short transverse.
A kind of aerodynamic energy loud speaker adopting above-mentioned vibrating diaphragm, comprise housing, magnet frame, vibrating diaphragm are installed in described housing and are positioned at two vibrating diaphragm framves at vibrating diaphragm two ends, the two ends up and down of described vibrating diaphragm are fixed on described vibrating diaphragm frame, two ends, left and right are fixed in described magnet frame, described magnet frame are provided with some permanent magnets that the short transverse along described vibrating diaphragm arranges.
Described housing is made up of face shield and backboard.
Described face shield and backboard are made up of permeability magnetic material.
Described permanent magnet is semi-annular shape.
The reference column that the fold that described vibrating diaphragm erection is equipped with some and described vibrating diaphragm is corresponding.
The invention has the beneficial effects as follows: the cross section of vibrating diaphragm of the present invention is arc, adopt the sound equipment tool of this vibrating diaphragm to have the following advantages:
1, traditional plane diaphragm sound equipment is solved in directive property, the problem that radiating acoustic energy is uneven, sound field is narrow, diffusion angle is broad not, namely in standard listening room under equidistant condition, the interior sound pressure level error amount in 180 degree, direction that is up to the standard minimizes, sound-filed simulation is even, makes the consistency that the hearer of diverse location reaches maximum.
2, under solving similarity condition and environment, tradition sound equipment is little in the acoustic density of treble, full not, propagate the problem that diameter is shorter, this is because the area of arc vibrating diaphragm is far longer than traditional vibrating diaphragm, and this is equivalent to the different directions pointed to respectively with nearest distance composition array by the high pitch loudspeaker of multiple point sound source in 180 degree.
3, under solving similarity condition and environment, the problem that traditional woofer is narrow in Hz-KHz, this is because the area of arc vibrating diaphragm is far longer than traditional vibrating diaphragm, extends greatly so obtain in Hz-KHz.Pneumatic high pitch loudspeaker is natively considerably beyond ball top high pitch loud speaker in hyperfrequency, and the present invention is because vibrating diaphragm area is much larger than traditional, pneumatic high pitch loudspeaker, so the range of its low frequency have also been obtained the lifting of more than multiple.
4, power and sound pressure level (loudness rank) the i.e. problem of efficiency of high pitch loudspeaker is solved, often particularly the power of pneumatic high pitch loudspeaker, efficiency are all lower for high pitch loudspeaker, but, the present invention is due to the increase of vibrating diaphragm area, corresponding electromagnetic system structure is also along with increasing, so on power and sound pressure level (loudness rank) i.e. efficiency, have also been obtained very large lifting.
