Abstract
The invented digital electroacoustical transducer includes vibrating diaphragm in permanent magnetism or ferromagnetism, electromagnet composed of N group of inductive windings, supporting body in acoustic permeability, fixed part also being as low pass damp for vibrating diaphragm. The vibrating diaphragm is fixed on the supporting body, and a gap between them keeps needed vibrating range. The electromagnet is also fixed on the supporting body. The electromagnet is composed of N group of inductive windings to meet digital requirement. Different combinations of electromagnet suit to circuits in multiple bits or one bit stream current. Current in electromagnet forms push pull force, making diaphragm vibrate. Vibration of diaphragm makes electromagnet induces current so as to complete electroacoustic and acoustoelectric conversion. The invention possesses high efficiency of conversion without need of complex A/D conversion.
Description
The invention provides a kind of digitlization electroacoustic loud speaker, it need not A/D D/A module, can directly digital signal be transferred to sound wave or transfer sound wave to the digital quantization signal.Relate to the improvement of electro-acoustic element.The conversion of traditional electrical acoustical signal must realize the signal A/D conversion digitlization of signal afterwards through analogue device.Reduction digital signal then D/A conversion back is reduced by analogue device.
The electroacoustic loud speaker that the purpose of this invention is to provide a kind of self matrix coder, the electromagnet matrix combination by N group inductance coil is formed realizes the conversion of many bit streams or a bit stream.
Electromagnet (2), entrant sound supporting mass (3), the vibrating diaphragm fixture that digitlization electroacoustic loud speaker of the present invention is made up of vibrating diaphragm (1), the N group inductance coil low pass damping body (4) of holding concurrently is formed.
The present invention is achieved in that vibrating diaphragm (1) is fastened on the entrant sound supporting mass (3) by the vibrating diaphragm fixture low pass damping body (4) of holding concurrently, and the electromagnet (2) that N group inductance coil is formed fixedly is embedded on the entrant sound supporting mass (3).Persevering magnetic of vibrating diaphragm (1) cording or ferromagnetic property film.
The present invention has following structure accompanying drawing
Electromagnet 3-entrant sound supporting mass 4-vibrating diaphragm fixture of forming of 1-vibrating diaphragm 2-N group inductance coil low pass damping body of holding concurrently wherein.
How the present invention realizes below in conjunction with the accompanying drawing narration.Electromagnet (2), entrant sound supporting mass (3), the vibrating diaphragm fixture that digitlization electroacoustic loud speaker of the present invention is made up of vibrating diaphragm (1), the N group inductance coil low pass damping body (4) of holding concurrently is formed.Vibrating diaphragm (1) is fastened on the entrant sound supporting mass (3) by the vibrating diaphragm fixture low pass damping body (4) of holding concurrently, and the electromagnet (2) that N group inductance coil is formed fixedly is embedded on the entrant sound supporting mass (3).When having electric current to pass through in the electromagnet of forming at N group inductance coil (2),, vibrating diaphragm (1) is formed push-pull effort, vibrating diaphragm (1) vibration sounding by the combination of N group electromagnet matrix.Otherwise during vibrating diaphragm (1) vibration, electromagnet induces electric current, by the combination of N group electromagnet matrix, finishes electroacoustic, acoustic-electric transfer process.The present invention is directed to different matrix combinations, can realize the conversion of many bit streams or a bit stream.
Claims (2)
1, a kind of digitlization electroacoustic transducer, electromagnet (2) entrant sound supporting mass (3) the vibrating diaphragm fixture that it is made up of vibrating diaphragm (1) the N group inductance coil low pass damping body of holding concurrently is formed (4).It is characterized in that: vibrating diaphragm is fastened on entrant sound supporting mass (3) and go up is connected by the vibrating diaphragm fixture low pass damping body (4) of holding concurrently.Electromagnet (2) fixedly is embedded in the entrant sound supporting mass (3).
2, according to claims 1 described digitlization electroacoustic transducer, it is characterized in that: vibrating diaphragm is for having permanent magnetic or ferromagnetic property film.
