Abstract
Introducing its feature of a kind of moving-magnetic type electric loudspeaker mainly is made up of high frequency magnetic loop, tone currents input fixed coil and closed moving winding etc.Overcome the shortcoming that the development of existing electrodynamic loudspeaker high impedance aspect is restricted, can not only be the analog audio current conversion sound directly and can be sound, for utmost point advantageous conditions has been created in sound signal power switch amplificationization and transformerless power amplifier systematization audio frequency modulated current Direct Transform such as pulsewidth, frequency modulation, amplitude modulation.
Description
The present invention relates to electrodynamic loudspeaker, electroacoustic transducer.
Known existing electrodynamic loudspeaker all is a low-resistance, handy power transformer power supply.
The moving-magnetic type electric loudspeaker of the present invention no matter application of high Low ESR or high or low power aspect can both be given full play to its advantage.The simulated sound electric current directly can be converted to sound, also the audio-frequency current of modulation such as pulsewidth, frequency modulation, amplitude modulation, number directly can be converted to sound, and moving-magnetic type electric loudspeaker can make enlarger save the high power transformer of the big cost of heavy energy consumption.
The high frequency magnetic loop that its feature of moving-magnetic type electric loudspeaker of the present invention is made of T type magnetic core post, U shaped magnetic core post shell also is wound with audio-frequency current input fixed coil and the closed moving winding that connects with the sound symphysis etc. is formed in T type magnetic core post lower end; Closed moving winding in the foregoing invention is the closed circuit that is in series by active coil and passive coil, and two coils are the two ends on the moving coil framework respectively.It is aerial that initiatively coil and passive coil are enclosed within the magnetic of the magnetic gap centre of magnetic loop and magnetic gap bottom respectively; Fixed coil in the foregoing invention also can have centre cap or other tap.
Attached picture in picture (2) and figure (3) are the electrical principle isoboles of moving magnetic speaker.General structure is shown in figure (1), and T type ferrite magnetic core post (1) ferrite stem shell (2) is coil (3) passive coil (4) magnetic gap (5) magnetic sky (6) moving coil framework (7) sound film dish (8) orientation film (9) lead-in wire (10) fixed coil (11) high frequency magnetic loop structure chart (4) initiatively.
The present invention and existing dynamic loudspeaker ratio can make that the audio amplification circuit structure is more simple, reliable, fidelity, owing to have the high resistant input, can under high voltage, work, so can save the high power transformer of the big cost of heavy energy consumption. Therefore have integrated cost and reduce, can realize that sound amplifier no power supply transformer and audio frequency switch power amplify synthetic positive effect.
Each scheme among the present invention is to implement best way of the present invention.
Claims (3)
1, the high frequency magnetic loop that constitutes by T type magnetic core post, U shaped magnetic core post shell of a kind of its feature of moving-magnetic type electric loudhailer and be wound with the audio-frequency current input in T type magnetic core post lower end fixedly paper circle and the closed moving winding that connects with the sound symphysis etc. are formed;
2, the closed moving winding in the foregoing invention is the closed circuit that is in series by active coil and passive coil, and two coils are the two ends on the moving coil framework respectively.It is aerial that initiatively coil and passive coil are enclosed within the magnetic of the magnetic gap centre of magnetic loop and magnetic gap bottom respectively;
3, the fixed coil in the foregoing invention also can have centre cap or other tap.
