Abstract
The utility model relates to an acoustic-optical stereo door core, which is composed of a casing and circuit. The front middle part of the casing is raised outwards, and characters or drawings and also an LED are arranged on the raised surface. The circuit is arranged at the notch of the back side. When used, the acoustic-optical stereodoor core is installed on a door. When someone knocks at the door, sound and light are embodied simultaneously. The acoustic-optical stereo door core has the advantages of brilliant color and strong stereo feeling. When the utility model is installed in spring festival or festivals, the festival atmosphere can be added.
Description
The utility model is a kind of acousto-optic stereo door core, is widely used in city and rural area.
Men Xin is attached on the door, and auspiciousness word of blissful word or the like and figure painting also claim the door god.Pasting Men Xin is a kind of traditional custom of the Chinese nation, do not wane no matter city, rural area are in vogue so far, especially the Spring Festival and celebrating date, people also will paste a core except that pasting distich, the happy expression that seems is clear, a kind of festive air is arranged, and along with the raising of educational level and technological level, the content and form of door core is innovation to some extent gradually.Mostly an at present popular door core is to write surplus on the red paper, and golden word or figure painting such as venerable old man or lady etc. though pattern, color are of all shapes and colors, are the planes, do not have third dimension, can sounding, and can be not luminous.
In order to increase festive air, the purpose of this utility model is that a kind of energy sounding and the simultaneously luminous stereo door core of energy will be provided.
The purpose of this utility model is achieved in that a core is made up of housing and circuit two parts.The front mid portion of housing 1 outwards protrudes, and word is arranged on convex surface 2 or draw 3, also has Light-Emitting Diode 4, and circuit 5 is contained in the back side of shell recess.
The utility model, elegant in appearance, sound, light embody simultaneously, and bright in luster, third dimension is strong.
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a side schematic view of the present utility model.
Fig. 3 is a circuit diagram of the present utility model.
Attached middle school: the 1st, housing.The 2nd, convex surface.The 3rd, word or picture.The 4th, Light-Emitting Diode.The 5th, circuit.
As Fig. 1, Fig. 2, shown in Figure 3, Men Xin is dimerous by housing and circuit, make the plane around the housing 1, the centre is made three-dimensional, and outwards protrude in the front, the height that protrudes is greater than the thickness of circuit, word being arranged on convex surface 2 or draw 3 as good fortune, spring, longevity or the like, also can be bust, mascot etc., also have light emitting diode 4 on the convex surface, circuit 5 is contained in the back side of shell recess.
Its structure: the base stage of the emitter stage of triode BG1 and the triode BG2 composition composite amplifier that joins, 1 pin input signal of the emitter stage of triode BG2 and ic chip joins, and 9 pin of the colelctor electrode of triode BG1, BG2 and ic chip positive pole common and power supply joins.The two ends of piezoelectric ceramic piece YD join with the base stage of BG1 and the emitter stage of BG2 respectively, convert vibration signal to voltage signal.3 pin output signals of the base stage of BG3 and ic chip are joined.5 pin of the emitter stage of BG3 and ic chip negative pole common and power supply joins, and the two ends of loudspeaker join with the positive pole of power supply and the colelctor electrode of BG3 respectively, and 4,6 pin of ic chip and light emitting diode D also connect, and 7,8 pin and resistance also connect.
During use, piezoelectric ceramic piece YD is fixed within the door-plate upper shell scope, and then the housing that circuit is equipped with at the back side also is fixed on the door-plate.
When the people knocks at the door, after piezoelectric ceramic piece YD is vibrated, convert vibration signal to voltage signal, after the amplifying circuit amplification via triode BG1, BG2 composition, transfer to 1 pin of music integrated block IC, promote the music signal that music integrated block IC is formed by certain program, export by 3 pin, this audio signal promotes loudspeaker Y and sends musical sound after BG3 amplifies, and diode 4 is luminous simultaneously.After treating that melody has been played, acousto-optic stops simultaneously automatically.
This core is with the hard sheet of PVC, and the synthetic materials such as paper, calcium are moulded, plastic-aluminum of moulding all can be made.The projection of door core can be made garden shape, polygon, square or the like, also can be only word or picture be made protrusion.Can also draw various patterns around the door core, add color, as smart as a new pin colourful.
