Description
The utility model relates to a kind of loudspeaker, particularly relates to a kind of two-way double diaphragm dynamic planar loudspeakers.
Present electronic vibrating membrane loudspeaker makes the part voice coil loudspeaker voice coil break away from effective magnetic field in mechanical motion, thereby cause distortion, and electricity/sound conversion efficiency is low owing to the defective of its magnet structure.Simultaneously, because the cone-shaped diaphragm that adopts has the degree of depth, there is phase differential in the sound wave that sends, and electroacoustic property is poor, even can produce acoustic short circuit.
The purpose of this utility model just provides a kind of high-fidelity, efficient height, two-way double diaphragm dynamic planar loudspeakers that electroacoustic property is good.
Further purpose of the present utility model just provides a kind of two-way double diaphragm dynamic planar loudspeakers of highly versatile.
Task of the present utility model is achieved in that the two-way double diaphragm dynamic planar loudspeakers of being made up of voice coil loudspeaker voice coil, vibrating diaphragm, magnet.Voice coil loudspeaker voice coil is square, and is arranged under the support of square skeleton in the square magnetic field that is made of four pairs of magnets.Every pair of magnet is formed by interior magnet steel and outer steel, and interior magnet steel is positioned at square voice coil loudspeaker voice coil inside.The pair of planar vibrating diaphragm is connected with the two ends of square skeleton respectively, and constitutes a hexahedron jointly with square skeleton.Since square voice coil loudspeaker voice coil fully " immersions " in magnetic field, and the plane diaphragm of employing eliminated the phase differential of sound wave, improved electricity/sound conversion efficiency, the fidelity height.
Further task of the present utility model is achieved in that the two-way double diaphragm dynamic planar loudspeakers of being made up of voice coil loudspeaker voice coil, vibrating diaphragm, magnet.Voice coil loudspeaker voice coil is square, and by centre tapped two groups of symmetric double wire-wound groups and around forming, 3 pairs of lead-in wires are fixed on the outer wall of cylinder by binding post.
Because it is the square structure of core that the utility model has adopted with square voice coil loudspeaker voice coil, make the magnetic field at voice coil loudspeaker voice coil place guarantee whole process evenly, and magnetic field intensity is much higher than traditional circular magnet steel; When square voice coil loudspeaker voice coil is in the magnetic field any position, can both following of accurate sensitivity be arranged to different frequency;
Plane diaphragm has been eliminated the phase distortion of sound wave, and is truer to the reduction of sound, and electroacoustic performance is good, has improved fidelity;
Adopt centre tapped two-wire and, can adapt to different power amplifiers and output impedance, highly versatile around voice coil loudspeaker voice coil;
The fillet of screw with highly elastic material replaces the accordatura circle, makes double diaphragm more synchronous to following of bass, and is sensitive more to the reaction of high pitch;
Alleviate overall vibration quality and resistance, improved the starting of oscillation sensitivity of double diaphragm;
Adopt two-way double diaphragm, reduced electrical power consumed.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of the fillet of screw and plane diaphragm.
The perspective view of Fig. 3 magnet.
Below in conjunction with embodiment the utility model is described in further detail.
