Abstract
The utility model relates to a double-voice coil electric loudspeaker which comprises a non-magnetic conductivity frame, a magnetic steel and a vibrating diaphragm, wherein, the frame is a rotating body, and the cross section of the frame forms an E shape. The magnetic steel which is clamped by an upper magnetic conductivity plate and a lower magnetic conductivity plate is fixed on an outer coil of the frame. A pole core column is fixed on an inner coil of the frame. An upper voice coil and a lower voice coil corresponding to the upper magnetic conductivity plate and the lower magnetic conductivity plate are positioned in an air gap among the pole core column, the upper magnetic conductivity plate and the lower magnetic conductivity plate. The voice coils are correspondingly fixed by a waviness frame. The utility model has the advantages of large driving force, and little distortion caused by non-linear distortion and nonuniform distribution of magnetic force lines.
Description
A kind of double-tone circle electrodynamic loudspeaker relates to moving-coil, moving plate or moving-wire type transducer.
Chinese patent application has been announced for No. 89208599.1 a kind of " double-coil loudspeaker reaches from the paraphase stereo set ", directly is connected with double-coil loudspeaker from the power amplifier level of paraphase stereo set, utilizes the double-tone circle of loud speaker to realize from the synthetic sound wave of paraphase.Its double-coil loudspeaker is to utilize general loud speaker, original voice coil loudspeaker voice coil is made the double-tone circle form.This utility model mainly is to utilize the double-tone circle to realize from the synthetic sound wave of paraphase.Chinese patent has been announced a kind of " novel combination type loud speaker " for No. 93242815.0, and it has increased bass voice coil loudspeaker voice coil, high pitch voice coil loudspeaker voice coil, tweeters diaphragms, high pitch sound tube in the structure of loud speaker.But this loud speaker has the distortion that magnetic line of force skewness causes in nonlinear distortion that magnetic steel material produces and the air gap.
The purpose of utility model provides a kind of double-tone circle electrodynamic loudspeaker, and it can effectively reduce distortion.
Utility model adopts such technical scheme: this double-tone circle electrodynamic loudspeaker includes non-magnetic conduction skeleton magnet steel and vibrating diaphragm, and skeleton is that rotary body and sanction face are shaped as the mountain font.Be fixed on by the magnet steel of upper and lower magnetic conductive board clamping on the outer ring of skeleton.The pole piece post is fixed on the skeleton inner ring, and in the air gap of upper and lower voice coil loudspeaker voice coil between pole piece post and upper and lower magnetic conductive board relative with upper and lower magnetic conductive board, the ripple frame is with the voice coil loudspeaker voice coil relative fixed.
Because the utility model adopts two magnetic gaps, double-tone coil structures to make motive force bigger, has reduced because the nonlinear distortion that magnetic steel material produced has been avoided the distortion that magnetic line of force skewness causes in the single working gas gap.
The concrete structure of utility model is provided by following embodiment and accompanying drawing thereof.
The double-tone circle electrodynamic loudspeaker structural representation that accompanying drawing the utility model proposes for foundation.
Below in conjunction with drawings and Examples the double-tone circle electrodynamic loudspeaker that foundation the utility model proposes is further described.
As shown in drawings, according to together general the same voice coil loudspeaker voice coil, magnet steel, vibrating diaphragm, the skeleton etc. of also including of electrodynamic loudspeaker of the double-tone circle electrodynamic loudspeaker that the utility model proposes.Skeleton (7) is a rotary body, and its cross section is the mountain font.Upper and lower magnetic conductive board (3,6) is magnet steel (5) clamping, and is installed on the outer ring of skeleton.Pole piece post (4) is installed on the inner ring of skeleton, and relative with upper and lower magnetic conductive board.Between pole piece post and upper and lower magnetic conductive board, form air gap thus.Upper and lower voice coil loudspeaker voice coil (2) is positioned at air gap, and links to each other with vibrating diaphragm (1).Simultaneously, voice coil loudspeaker voice coil is by ripple frame (8) relative fixed.For more effectively suppressing the circular runout of voice coil loudspeaker voice coil, the ripple support is installed all on upper and lower voice coil loudspeaker voice coil.And the direction of winding of two voice coil loudspeaker voice coils is preferably opposite, to offset anti-demagnetizing field.
Claims (3)
1, a kind of double-tone circle electrodynamic loudspeaker, include non-magnetic conduction skeleton, magnet steel and vibrating diaphragm, it is characterized in that skeleton is a rotary body, and the cross section is the mountain font, be fixed on by the magnet steel of upper and lower magnetic conductive board clamping on the outer ring of skeleton, the pole piece post is fixed on the skeleton inner ring, and in the air gap of upper and lower voice coil loudspeaker voice coil between pole piece post and upper and lower magnetic conductive board relative with upper and lower magnetic conductive board, the ripple support is with the voice coil loudspeaker voice coil relative fixed.
2, double-tone circle electrodynamic loudspeaker according to claim 1 is characterized in that all being equipped with on the upper and lower voice coil loudspeaker voice coil ripple frame.
3, as double-tone circle electrodynamic loudspeaker as described in claim 1 or 2, it is characterized in that the direction of winding of upper and lower voice coil loudspeaker voice coil is opposite.
