Abstract

The utility model discloses an open pronunciation device which consists of a magnetic steel and a splint, a T-shaped soft iron core, a spring plate, a driving coil whose bottom part is arranged with a driving rod, the lower part of the driving rod is provided with a balance plate used to keep the pronunciation device stable; the T-shaped soft iron core is cover-arranged between the magnetic steel and the splint and forms a certain gap together with the magnetic steel and the splint, the driving coil is centrally fixed in the gap formed by the magnetic steel, the splint and the T-shaped soft iron core after connecting with the spring plate, and can make a reciprocating motion by the electromagnetic effect in the gap. The utility model's driving coil can generate an electromagnetic effect together with the T-shaped soft iron core, the magnetic steel and the splint after being electrified by driving current, the driving rod transfers the kinetic energy generated by the electromagnetic effect out. If only the utility model is arranged on arbitrary plane such as a desktop, a glass, a wood slab and so on, the kinetic energy transferred out by the driving rod can be transferred to the plane where the driving rod lies to send out sound, thus the resonance is introduced to arbitrary plane to send out multi-directional sound.

Description

A kind of open type sounder

Technical field

The utility model 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.

The utility model content

At the problem of above-mentioned existence, the purpose of this utility model is to provide a kind of open type sounder, and 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 utility model comprises: magnet steel and clamping plate, the T shape soft iron heart, latch plate, drive coil, 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 the described magnet steel.

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 utility model 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 utility model 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; The utility model tonequality is soft in addition, phonation efficiency is high, and sound does not have obvious directivity.

Embodiment

As shown in Figure 1, the utility model comprises: magnet steel and clamping plate 3, the T shape soft iron heart 2, latch plate 4, drive coil 5, and 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 utility model 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 utility model can also be designed to comprise that one increases and expand the mechanism of the power amplifier unit 8 of the utility model function, this power amplifier unit 8 comprises power supply 9, power amplification 10, audio frequency input 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 the utility model structure 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 utility model is particularly suitable for the office space, uses when the leisure occasion maybe needs to go out to carry.
