Abstract
The utility model relates to a lighting piezoelectric ceramic loudspeaker, comprising a horn, a central washer, a paper basin and a back cover. The central washer is arranged at the bottom of the horn, and the back cover is firmly connected with the central washer. A light-emitting device is arranged on the central washer, and a bracket is arranged in the back cover. Two ends of the paper basin are arranged on the bracket. A piezoelectric ceramic piece is arranged in the center of the bracket, and the piezoelectric ceramic piece is firmly connected with the bottom of the paper basin. Two ends of the bracket are provided with an inductance coil, and the inductance coil is connected with a first wire connecting terminal arranged on the back cover after the inductance coil is connected with a capacitance in series. One end of the piezoelectric ceramic piece is connected with the inductance coil, and the other end is connected with a second wire connecting terminal arranged on the back cover. The utility model has beneficial effects of good effect, compact conformation, professional design, simple use and manufacture and high performance-cost ratio.
Description
Technical field
The utility model relates to a kind of public address set, especially a kind of luminous piezoelectric ceramic loud speaker.
Background technology
At present used electrodynamic loudspeaker can only sounding can not be luminous, function ratio is more single, such loud speaker makes the people can only obtain acoustically enjoyment.
The utility model content
The utility model will solve the defective of above-mentioned prior art, provides a kind of rational in infrastructure, can sounding again can be luminous the luminous piezoelectric ceramic loud speaker, make the people obtain the enjoyment of the sense of hearing and vision.
The utility model solves the technical scheme that its technical problem adopts.This luminous piezoelectric ceramic loud speaker comprises horn, and centre circle, cone and bonnet, centre circle are located at the horn bottom, and bonnet is fixed on the centre circle, and light-emitting device is located on the centre circle, is provided with support in the bonnet, and the cone two ends are located on the support; Be provided with piezoelectric ceramic piece in the middle of the support, this piezoelectric ceramic piece is fixed in the cone bottom; The support two ends are provided with inductance coil, after this inductance coil series capacitance be located at bonnet on first binding post be connected; Piezoelectric ceramic piece one end is connected with inductance coil, and the other end is connected with second binding post on being located at bonnet.
The effect that the utility model is useful is: the utility model is effective, compact conformation, reasonable in design, uses and makes simply, the cost performance height.
Description of drawings
Fig. 1 is that the utility model partly cuts open structural representation;
Description of reference numerals: luminous tube 1, reflective base 2, transparent throat taps 3, horn 4, centre circle 5, cone 6, coil 7, piezoelectric ceramic piece 8, luminous tube electrode 9, bonnet 10, support 11, the first binding posts 12, the second binding posts 13.
Embodiment
Below in conjunction with drawings and Examples the utility model is described further: this luminous piezoelectric ceramic loud speaker comprises luminous tube 1, reflective base 2, by the horn 4 that transparent plastic is made, centre circle 5, cone 6 and bonnet 10, centre circle 5 is located at horn 4 bottoms, and bonnet 10 is fixed on the centre circle 5.Be provided with the throat taps of being made by transparent plastic 3 in the horn 4, this throat taps 3 places on the centre circle 5.Be provided with support 11 in the bonnet 10, cone 6 two ends are located on the support 11; Be provided with piezoelectric ceramic piece 8 in the middle of the support 11, this piezoelectric ceramic piece 8 is fixed in cone 6 bottoms; Support 11 two ends are provided with inductance coil 7, after these inductance coil 7 series capacitances be located at bonnet 10 on first binding post 12 be connected; Piezoelectric ceramic piece 8 one ends are connected with inductance coil 7, and the other end is connected with second binding post 13 on being located at bonnet 10.
During assembling, luminous tube 1 is contained in the reflective base 2, reflective base 2 and transparent throat taps 3 bonding being contained on the centre circle 5, and horn 4 is contained on the centre circle 5, and cone 6, coil 7 are contained on the centre circle 5, and piezoelectric ceramic piece 8 is bonded on the cone 6.Flow into from luminous tube electrode 9 and voice coil loudspeaker voice coil when voice-frequency signalling current during work, realize the function of electric light conversion by electronic circuit, the photochromic variation of luminous tube is directly proportional with input tone currents size and is relevant with the voice frequency of input.
During use, audio voltage after inductance coil one frequency division and the impedance matching, is passed to piezoelectric ceramic piece 8 through electric capacity, and piezoelectric ceramic piece 8 is promptly crooked up or down, produces with audio voltage and vibrates accordingly.Utilize this vibration, just can promote cone 6 and produce vibration, thereby the excitation air is sounded.
