Abstract
An impedance match coaxial loudspeaker of the utility model comprises front and rear concentrating flux plates, a magnet, a field center column, a bass speech coil, a centering support chip, a plate rail, blank pressing, a high and mediant bracket, a high and mediant diaphragm, a piezoelectric ceramic slice, a fixed coil coupling reaction of high and mediant, a bass diaphragm, etc. The fixed coil coupling reaction of high and mediant is arranged on the field center column of the base loudspeaker and makes use of the connection in parallel of the piezoelectric ceramic slice and the fixed coil coupling reaction of high and mediant to comprise the resonator system, and as a result, the utility model can be generally operated in the audio. The high, mediant and bass can sound on the same axial point, which makes the optimum efficiency of carrying-off phase distortion.
Description
The utility model relates to a kind of loud speaker, particularly a kind of impedance matching formula coaxial loudspeaker.
At present, the bass electrodynamic loudspeaker is only made bass and is used, and high pitch loudspeaker is only made high pitch and used, and can not take into account mutually.When reality is used, be to install at grade respectively, and must use frequency divider.Obviously, do not pronounce on the point because all loud speakers do not coexist, so phase distortion is very big, frequency divider has brought loss and time-delay simultaneously, and distortion is further increased.
The purpose of this utility model is to avoid above-mentioned the deficiencies in the prior art part and a kind of phase distortion of eliminating is provided, and makes pronunciation reach the impedance matching formula coaxial loudspeaker of optimum efficiency.
The purpose of this utility model can reach by following measure: the utility model comprises by forward and backward magnetic conductive board, magnet, a stem, bass voice coil loudspeaker voice coil, centring disk, plate rail, flanging, high middle pitch support, high middle pitch vibrating diaphragm, bass vibrating diaphragm, it is characterized in that: also have piezoelectric ceramic piece, high middle pitch inductive coupling fixed coil, have groove on the stem on the scene, be wound with high middle pitch inductive coupling fixed coil on the groove, high middle pitch inductive coupling fixed coil and piezoelectric ceramic piece are connected in parallel, and form resonator system.
The purpose of this utility model can also reach by following measure: piezoelectric ceramic piece is contained in the high middle pitch support, and high middle pitch vibrating diaphragm is adorned thereon, and the bass voice coil loudspeaker voice coil is loaded on the centring disk.The diameter of field stem is greater than the diameter of high middle pitch support, high middle pitch vibrating diaphragm and piezoelectric ceramic piece.
Fig. 1 is a structure cutaway view of the present utility model;
Fig. 2 is an electrical schematic diagram of the present utility model;
The utility model is described in further detail below in conjunction with accompanying drawing (embodiment):
With reference to Fig. 1, the utility model is made up of preceding magnetic conductive board 1, magnet 2, a stem 3, back magnetic conductive board 4, bass voice coil loudspeaker voice coil 5, centring disk 6, plate rail 7, flanging 8, high middle pitch support 9, high middle pitch vibrating diaphragm 10, piezoelectric ceramic piece 11, high middle pitch inductive coupling fixed coil 12, bass vibrating diaphragm 13.Have groove on the stem 3 on the scene, be wound with high middle pitch inductive coupling fixed coil 12 on the groove, high middle pitch inductive coupling fixed coil 12 is connected in parallel with piezoelectric ceramic piece 11 electricity, forms resonator system.Piezoelectric ceramic piece 11 is contained in the high middle pitch support 9, and high middle pitch vibrating diaphragm 10 is adorned thereon, and bass voice coil loudspeaker voice coil 5 can be with the motion campaign of bass vibrating diaphragm 13.
The output of stereo set is connected on the bass voice coil loudspeaker voice coil 5, when bass voice coil loudspeaker voice coil 5 has electric current to flow through, promotes 13 motions of bass vibrating diaphragm, the excitation air, and send all-bottom sound; Induce electric current through on the high middle pitch inductive coupling fixed coil 12 of impedance matching simultaneously, driving piezoelectric ceramic piece 11 sounding.Thereby reach the purpose that same axle point sounding is eliminated phase distortion.
With reference to Fig. 2, inductance L 1 is bass voice coil loudspeaker voice coil 5, and inductance L 2 is high middle pitch inductive coupling fixed coil 12, capacitor C is piezoelectric ceramic piece 11; Capacitor C and inductance L 2 are formed the parallel resonance system.
The utility model has following advantage compared to existing technology:
1. loudspeaker can be worked in audio frequency comprehensively, and high, medium and low sound can at same axle point sounding, play the optimum efficiency of eliminating phase distortion.
2. the comprehensive volume of loudspeaker is further dwindled, rational in infrastructure, easy to use, reliable operation.
