Description of drawings
Fig. 1 is the structural representation of resonance audio amplifier.
Embodiment
Be elaborated below in conjunction with the technical scheme of accompanying drawing to the utility model.
As shown in Figure 1, said resonance audio amplifier comprises resonance plate 1, flexible member 3, body 5, permanent magnet 6 and coil 8.Said resonance plate 1 is arranged on the coil rack 2; Said permanent magnet 6 is installed on the said body 5, and the outside of said permanent magnet 6 is with the said coil rack 2 that is wound with said coil 8, thereby forms magnetic circuit.Said coil rack is fixed on the said body 5 through said flexible member 3 hangingly.Preferably, said permanent magnet 6 is installed on the said body 5 through coil holder 7.
Preferably, said body has recess, and said permanent magnet 6 is installed in the said recess.Preferably, said coil rack has the recess of holding, and said permanent magnet 6 is incorporated in said holding in the recess.
One end and the said coil rack of said flexible member 3 are fixed, and its other end is fixed on the said body, preferably, are fixed on the body through screw 4.Therefore, owing to the existence of said flexible member 3, relative displacement can take place between body and the coil rack.
Preferably, the number of said flexible member is at least 2.
Preferably, said resonance plate 1 is arranged on the said coil rack 2 through a connecting rod.
Preferably, said resonance audio amplifier has water-tight device, therefore can be applicable in the bathroom, even can in the water of swimming pool, use.
During work, to the coil 8 of the said magnetic circuit electric current (being acoustic current-meter) through z direction shown in Figure 1, on corresponding direction with it, said resonance plate produces the power on the x direction immediately, and the y direction is the direction of magnetic circle among Fig. 1.If change the size and Orientation of the acoustic current-meter in the said coil 8 of input, corresponding with it, the corresponding variation also takes place in the size of said power on above-below direction.According to the difference of the direction of the said power that takes place, the resonance plate in the said magnetic circuit also moves up and down, thereby makes glass or desktop also equally produce same sound with loudspeaker.
The resonance audio amplifier is different with common audio amplifier, and this is because the magnetic circuit with flexible member of suspension causes, and resonance plate and magnetic circuit are fixed as one and thresh same action, and promptly absorption, resilience each other has identical amplitude.When the speed of amplitude slow (being that frequency is low) time, magnetic circuit also keeps identical frequency to vibrate; And when accelerating (be frequency high) in the speed of amplitude, magnetic circuit is because the weight of himself and can't cater to vibration, so the also corresponding minimizing of its speed.Audio amplifier in the utility model makes with the contacted object of resonance plate and resonates, and is visualized as the sound-producing device of audio amplifier to this object.
Resonance audio amplifier in the utility model does not have jolting plate, as long as the body placement on the table, the contact chip of its bottom is contacted with desktop, and makes desktop take place to resonate and become audio amplifier; Further because desktop integral body all become audio amplifier, and the recipient to constraint seldom, therefore can produce the volume that sounds same by vibration; In addition, when the platform of placing not simultaneously, can send different tone colors according to the variation of the material of platform, the material of said platform can be metal, stripping glass, stone material, timber etc.For example, be placed on the timber and will embody more intense bass, place and to embody a kind of more intense air floating sense, salubrious high pitch when on glass.In addition, said resonance audio amplifier has the little characteristics of volume, is placed on narrow space, like the kitchen, and can not feel according to the space, further, though this resonance audio amplifier is little, harmonious resonance power can be arranged also.In addition, said resonance audio amplifier has the more stable characteristics of range.Audio amplifier in the past, the vibration of the oscillating plate that it is inner is that the vibration of air is sounded, and the resonance audio amplifier is through becoming oscillating plate to the object of contact, its sound is through the vibration transfer of air, so range is more stable.Therefore at last, said resonance audio amplifier has the advantages that sound can connect, and this is to sound through vibration force because of said resonance audio amplifier, can connect with contactant, even also can hear the sound of same volume at opposition side.
The above is merely the preferred embodiment of the utility model; Be not thus the restriction the utility model claim; Every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the utility model.
