Description
Technical field:
The utility model relates to the sound-producing device technical field, refers in particular to a kind of sound-producing device with jettron.
Background technology:
In order to improve the interest of printed matters such as postcard, greeting card, the applicant applied for once that name is called the utility model patent of " the luminous printed matter of turn that can become stereopsis ", saw that the patent No. is: 200620065405.4 Chinese utility model patent specification.Adopt three-dimensional turn light-emitting device in this patent, can form the effect of similar birthday cake like this, cooperate birthday card, can bring beyond thought pleasantly surprised to the user.But this technical scheme has only provided visual effect, and it also can't realize the interaction effect between people and the birthday card.
In addition, the applicant once proposed " a kind of switch ", saw that number of patent application is: 200920051712.0 Chinese utility application specification, it has proposed a kind of switch that can touch by air-flow, the air-flow touch switch that is blown into by the people.
The utility model content:
Technical problem to be solved in the utility model is exactly in conjunction with above-mentioned prior art, and a kind of sound-producing device with jettron is provided, and this device not only can provide good visual effect, and has jettron simultaneously, and the effect of light is blown out in simulation.In addition, the utility model combines the loudspeaker of jettron and sounding, simplifies the structure of product.
For solving the problems of the technologies described above, the utility model has adopted following technical scheme: this device comprises supporting body and the circuit that is arranged on the supporting body, this circuit comprises at least: the master switch of loudspeaker, illuminator and circuits for triggering, on supporting body, offer vocal hole, loudspeaker in the circuit are positioned at this vocal hole below, are provided with coil in the vibrating membrane of loudspeaker, in this coil place in circuit, extraneous air communication is crossed vocal hole and is entered, and the coil that touches on the loudspeaker produces electromagnetic signal.
Coil on the described loudspeaker is connected with amplifier in the circuit, by amplifier the electromagnetic signal that coil produces is amplified.
Described supporting body is a printed matter, and its surface is provided with molding body.
Described supporting body is a greeting card, and the molding body on it is a birthday cake, and the illuminator in the circuit is positioned at the candle wick place of candle on the birthday cake.
When using the utility model, at first trigger master switch, that the illuminator on the supporting body begins is luminous, loudspeaker begin to play music.When music finishes, the user can blow to the vocal hole position, and air communication is crossed vocal hole and entered supporting body inside, arrives on the vibrating membrane of loudspeaker, the coil that be positioned on the vibrating membrane this moment will vibrate with vibrating membrane, coil produces a faint electromagnetic signal in the magnetic field of loudspeaker, this electromagnetic signal is received by the circuit control chip after amplifying through amplifier, control chip will send signal, make illuminator extinguish, so just can form the effect of " blowing-out " illuminator, have interest.
After adopting said structure, the utlity model has following advantage:
1, with respect to present product, by pneumatic trigger switch is set in circuit, touches by air-flow, and triggering signal is delivered to central processing unit in the circuit, signal extinguishes illuminator after central processing unit is handled, to reach the effect of " blowing-out " light.
2, the utility model combines jettron and loudspeaker, makes the simple in structure, compact of product like this.
Description of drawings:
Fig. 1 is a front view of the present utility model;
Fig. 2 is a circuit diagram of the present utility model.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is further described:
See Fig. 1～2, present embodiment comprises: supporting body 1 and the circuit 2 that is installed in the supporting body 1.Wherein, supporting body 1 is a printed matter in the present embodiment, for example is greeting card, postcard etc.
Offer some vocal holes 11 on supporting body 1, this vocal hole 11 constitutes a sounding zone, and the loudspeaker 21 in the circuit 2 are located in this generation area below, and the audio frequency of being convenient to loudspeaker 21 like this plays back by the sounding zone.And loudspeaker 21 also face this below, sounding zone, and Wai Jie air-flow can enter in the supporting body 1 by vocal hole 11 like this, touch the vibrating membrane on the loudspeaker 21.
The vibrating membrane of loudspeaker 21 is provided with coil, in this coil place in circuit 2.Cross vocal hole 21 as the air communication in the external world and enter back (generation of air blowing situation), under the air-flow impetus, the vibrating membrane of loudspeaker 21 begins vibration, drives the coil vibration simultaneously.Owing to be provided with magnet in the loudspeaker 21, the coil vibration will produce electromagnetic signal in magnetic field.Certainly, this electromagnetic signal is very faint, be not enough to trigger central processing module 25, described coil is connected with amplifier 24, described electromagnetic signal is amplified through amplifier 24, enters central processing module 25 (control chip) then and makes a start really, thereby trigger central processing module 25, central processing module 25 will send instruction, make illuminator 22 extinguish.Certainly, in actual design process, in order to prevent that the coil on the loudspeaker 21 from can not produce response because of other extraneous factors, when central processing module 25 is programmed, should there be a time-delay response time that coil should be produced electromagnetic signal, 0.5 second-1 second delay time for example can be avoided being not intended to or accidental signal triggering central processing module 25 that other environmental stimuli trigger windings produce like this.
In order to increase the interest of product, adopt the supporting body 1 of birthday card to be provided with a molding body 12, this molding body 12 is for inserting the birthday cake of birthday candle, and illuminator 22 is as the wick of candle, and vocal hole 11 is positioned at the zone of molding body 12.During use, after the user opens birthday card, at first trigger master switch 23, illuminator 22 beginnings on the supporting body 1 are luminous, loudspeaker 21 begin to play the birthday song, are trapped among the cake that sticks with birthday candle as the people who celebrates joyously and congratulate on every side.When music finished, the user can blow to vocal hole 11 positions, and air communication is crossed vocal hole 11 and entered supporting body 1 inside, produces electromagnetic signal, and central processing module 25 sends instruction after receiving this triggering signal, makes illuminator 22 extinguish.So just can form the effect of " blowing-out " birthday candle, have interest.
Loudspeaker 21 also can produce vibration in the course of the work in the utility model, and promptly in the process of loudspeaker 21 sounding, coil 21 also can produce electromagnetic signal.For this electromagnetic signal and extraneous electromagnetic signal of blowing are distinguished, can in central processing module 25 programming processes of circuit 2, design corresponding program, make loudspeaker 21 in sounding, the electromagnetic signal of ignoring in the coil to be produced is in order to avoid produce the interference of signal.
Certainly, the above only is the several examples of the utility model, be not to limit the utility model practical range, all equivalences of doing according to the described structure of the utility model claim, feature and principle change or modify, and all should be included in the utility model claim.
