Abstract
The invention discloses a shock-wave converter, wherein a coil is arranged in a magnetic field formed by a magnetic-circuit device. One end of the coil is fixed on a centering spring, while the other end of the coil is connected with a current lead wire. The centering spring is fixedly connected with one end of a vibration transmission device, while the other end of the vibration transmission device is contacted with a vibration medium. The centering spring is fixed on the magnetic-circuit device or an article fixedly connected with the magnetic-circuit device. When in use, the coil generates vibration in the magnetic field after getting electricity and drives the centering spring to vibrate; the vibration is transmitted by the vibration transmission device so that the rigid vibration medium contacted with the vibration transmission device generates slight vibration sound.
Description
Technical field
The present invention relates to the stereo set field, is about a kind of shock-wave converter specifically.
Background technology
The main flow of the employed audio converter in current stereo set field is traditional coil-moving speaker; It is to be made up of permanent magnet system, voice coil loudspeaker voice coil and cone; The bonding integral structure of voice coil loudspeaker voice coil and cone props up sheet and hangs in the belt magnetic gap that is made up of permanent magnet through deciding core; The alternating magnetic field that produces during through alternating current when voice coil loudspeaker voice coil makes voice coil loudspeaker voice coil produce motion with permanent magnetic field generation effect, and is near and promote cone and produce the motion sounding.But conventional loudspeakers exists many disadvantages, and Hz-KHz is narrow, directive property difference etc. has all seriously influenced the playback of sound, has restricted it the further developing of electroacoustic field, and becomes the bottleneck of loud speaker development.
According to our research and development achievement for many years, the present invention has designed a kind of novel shock-wave converter that is used for audio area, when keeping the audio-frequency transducer each item advantage of Giant Magnetostrictive Materials Containing RE as driving element; It is high to have solved the external product production cost, low frequency shortcoming, and problem such as finished-product volume is excessive; And the output energy is big, and response speed is fast, bandwidth; Fidelity is good, and reliability is high, makes the production of powerful high-efficient flat-plate loud speaker become possibility.
Summary of the invention
The purpose of this invention is to provide a kind of improved shock-wave converter of structurally having done, it is narrow to have solved the Hz-KHz that exists during conventional loudspeakers is used, defectives such as directive property difference; Also solved audio-frequency transducer the efficiency-cost ratio low and production cost high problem of Giant Magnetostrictive Materials Containing RE simultaneously as driving element.
The technical scheme that realizes above-mentioned purpose is:
A kind of shock-wave converter comprises magnetic loop device and coil, and an end of coil is fixed on the centering spring pieces; Coil places the magnetic field that the magnetic loop device forms simultaneously, another termination current feed of coil, and said centering spring pieces is fixedly connected with an end that passes the shake device; The other end that passes the shake device joins with the vibration medium; Centering spring pieces be fixed on the magnetic loop device or with the affixed object of magnetic loop device on, the vibration medium is a rigid objects, coil can be exoskeletal rigidity coil; Coil also can have skeleton, and is wrapped on the rigid backbone.
Operation principle of the present invention narration is as follows: the vibration and drive centering spring pieces and vibrate in magnetic field of voice coil loudspeaker voice coil energising back, this vibration is vibrated the small vibration sounding of medium generation through the rigidity that passes the transmission of shake device and make and pass the shake device to contact.The present invention has following advantage:
1. because the present invention is simple in structure; Has stronger magnetic field in the gap at voice coil loudspeaker voice coil place; Only need very little voice coil loudspeaker voice coil electrical current just can make voice coil loudspeaker voice coil produce stronger vibration; Solve Giant Magnetostrictive Materials Containing RE as the low defective of the audio-frequency transducer efficiency-cost ratio of driving element, improved the installability of audio frequency apparatus greatly.
2, owing to adopt simple biography shake device structure among the present invention, the coil vibration is easy to vibrate the vibration of media sounding through passing the transmission of shake device thereby make, and makes the sound wave non-directive of generation, and response is fast, bandwidth, and fidelity is good.
3, the present invention is easy to maintenance in addition, and is with low cost, and volume is little, in light weight, and installation is easy to carry.

Embodiment
Below in conjunction with embodiment operation principle of the present invention is specifically described:
A kind of shock-wave converter comprises magnetic loop device and coil 1, is fixed on the gap, magnetic field that the coil on the centering spring pieces places the magnetic loop device to form; Coil connects current feed 6 and is connected with external power source; Pass shake device 4 one ends and be fixedly connected with centering spring pieces 3, the other end contacts with vibrating medium 5, centering spring pieces through screw 2 be fixed on the magnetic loop device or with the affixed object 9 of magnetic loop device on; The vibration medium is a kind of rigid material object; Coil can be a kind of exoskeletal rigidity coil, can be the coil that is wrapped on the rigid backbone also, like Fig. 3.When the present invention works, in magnetic field, produce after the voice coil loudspeaker voice coil energising to vibrate and drive centering spring pieces and vibrate, the vibration warp passes and shakes the small vibration sounding of rigidity vibration medium generation that the device transmission makes and pass the shake device to contact.
