Abstract
The invention discloses an open pronouncing device including, a magnetic steel with splint, a T-shaped soft iron core, a spring plate and a driving coil, in which, the driving pole is installed on the bottom of the coil, under which, a balance film maintaining the pronouncing device stable is fixed. The T-shaped soft iron core incases in the middle alnico and splint, which forms a certain slot. The connection of driving coil and spring plate fixes in the slot and can move reciprocating through electromagnetic effect. When getting through the driving current, the driving coil generates electromagnetic effect with iron core, alnico and splint, from which, kinetic energy will be conveyed by driving pole. If it is placed on any plane, kinetic energy will be transmitted to the plane and give out sound and cause surface resonate.
Description
Technical field
The present invention relates to a kind of pronunciation device.
Background technology
Present widely used loud speaker generally includes magnet steel and clamping plate, the T shape soft iron heart, voice coil loudspeaker voice coil, sound basin and sound basin frame etc.Voice coil loudspeaker voice coil is under the drive current effect, and the magnetic gap of forming with the T shape soft iron heart, magnet steel and clamping plate produces galvanomagnetic effect, directly drives sound basin sounding.This mode is pronounced relatively poor, and in order to improve effect, loud speaker is mounted in the casing usually, improves voice effect by casing, and casing can adopt single kind or multiple material to make, and multiple shape and structure are arranged.This loud speaker adds the audio amplifier that casing is formed, though can make acoustics reach more perfect degree, has a lot of weak points, and for example: 1, volume is big, is not easy to carry or moves; 2, phonation efficiency is low and tangible directivity arranged; 3, need to use lot of materials and technology very complicated; Produce, transportation and using all needs than large space, thereby production and consumer cost are higher.
Summary of the invention
At the problem of above-mentioned existence, the object of the present invention is to provide a kind of open type sounder, this device volume is small and exquisite, promptly need not to rely on traditional sound basin pronunciation, does not need that also casing is installed and improves voice effect.
For achieving the above object, a kind of open type sounder of the present invention comprises: magnet steel and clamping plate, the T shape soft iron heart, latch plate, drive coil, and the drive coil bottom is provided with drive rod, and the bottom of drive rod is equipped with and keeps the stable balancing patch of described pronunciation device; The T shape soft iron heart is sleeved in the middle of magnet steel and the clamping plate, and form certain slit (magnetic gap) with magnet steel and clamping plate, drive coil be fixed on the slit that the described T shape soft iron heart and described magnet steel and clamping plate form after described latch plate is connected between two parties, and can in this slit, pass through the galvanomagnetic effect reciprocating motion, when drive coil passed through electric current, this drive coil was passed to electromagnetism kinetic energy on any by the drive rod that is provided with in its bottom and sounds.
Further, also comprise a counter weight device, this counter weight device is installed on described magnet steel or other suitable position.
Further, comprise that also one increases and expand the power amplifier unit of described open type sounder function, this power amplifier unit comprises power supply, power amplification and audio frequency input, described power supply, power amplification, audio frequency input link to each other successively with drive coil, audio frequency input any equipment that has audio frequency output that is used to plug into, (as CD and other storage medium) DVD, CD, MP3 etc.
Further, comprise that also one is used to show the display unit of whole system operation situation.
Drive coil of the present invention is by behind the drive current, produce galvanomagnetic effect with the T shape soft iron heart, magnet steel and clamping plate, drive rod transmits out with the kinetic energy that galvanomagnetic effect produces, as long as the present invention is placed on the small plane, as desktop, glass, plank etc., the kinetic energy that drive rod transmits out will be delivered on the plane that is placed, and sounds thereby drive arbitrary face (can be plane or Any shape area); Therefore not only saved sound basin, casing, and volume small and exquisite, be easy to carry, saved a large amount of raw material and production and usage space; Tonequality of the present invention in addition is soft, phonation efficiency is high, and sound does not have obvious directivity.
Description of drawings
Fig. 1 for the present invention not with the structural representation of power amplifier unit;
Fig. 2 has the structural representation of power amplifier unit for the present invention.
Embodiment
As shown in Figure 1, the present invention includes: magnet steel and clamping plate 3, the T shape soft iron heart 2, latch plate 4, drive coil 5, drive coil 5 bottoms are provided with drive rod 6, and the bottom of drive rod 6 is equipped with and keeps the stable balancing patch 7 of pronunciation device; The T shape soft iron heart 2 is sleeved in the middle of magnet steel and the clamping plate 3, and form certain slits (magnetic gap) with magnet steel and clamping plate 3, drive coil 5 be fixed on the slit that the T shape soft iron heart 2 and magnet steel and clamping plate 3 are formed after latch plate 4 is connected between two parties, and can in this slit, pass through the galvanomagnetic effect reciprocating motion, when drive coil 5 passed through electric current, this drive coil 5 was passed to electromagnetism kinetic energy on any by the drive rod 6 that is provided with in its bottom and sounds.In addition, on magnet steel 3, also be provided with counter weight device 1.
During use, the present invention is placed on any plane, drive rod 6 just transmits out with the kinetic energy that galvanomagnetic effect produces, the kinetic energy that transmits will be delivered to and cause on the plane that is placed that vibration sounds, and can cause more large-area arbitrary face resonance, thereby send the splendid sound of effect.
As shown in Figure 2, the present invention can also be designed to comprise that one increases and expand the mechanism of the power amplifier unit 8 of function of the present invention, this power amplifier unit 8 comprises that power supply 9, power amplification 10, audio frequency import 11 and display unit 12, power supply 9, power amplification 10, audio frequency input 11 link to each other successively with drive coil 5, be used for inputing to from audio frequency whole links of output, display unit 12 is used to show the whole system operation situation.
Though structure of the present invention is simple, its tune is different fully with traditional tune, mainly is to utilize the resonance effect to carry out sounding, and is therefore not only soft at the sound that is generated by the plane that is placed, and do not have obvious directivity.The present invention is particularly suitable for the office space, uses when the leisure occasion maybe needs to go out to carry.
