Abstract

The utility model discloses a flame flip-over type music candle, composed of a candle body of the candle body part, a candle wick, two guide wires and a button cell in the sounding circuit, a triode Q, capacitances C1 and C2, a small bugle, and a music integrated sheet. The two guide wires are electrically connected with the sounding circuit, and the two guide wires are arranged at the candle wick and not contacted with each other, and can communicate the circuit through the burning flame of the candle wick, and the conduction of the triode Q is triggered, the music integrated sheet is played, the flame is burned out, and the Q is stopped. The music candle has simple structure, low manufacture cost, reliable performance, big sound volume, and easy to be popularized to thousands of families.

Description

Music candle

The utility model relates to flame trigger-type musical candle.

Known musical candle be not volume too the macrostructure complexity be exactly that performance is bad, as " photosensitive formula musical candle ", " heat-sensitive type musical candle ", the ubiquity performance is unreliable, the manufacturing process complexity, the cost height is difficult to apply.

The purpose of this utility model is to overcome the defective of prior art, focuses on the acoustics circuit and is simplified, and the musical candle that a kind of volume is littler, cost is lower is provided.

Embodiment of the present utility model is with flame triggering circuit conducting principle, because air ionization in flame becomes conductor, is equivalent to insert a resistance, makes the triode conducting trigger music integrated chip, lights i.e. ring, makes music and flame synchronous.One-piece construction is made up of candle body portion and acoustics circuit, the candle body portion comprises candle body, candle wick, two leads, connect acoustics circuit by these two leads, the peripheral circuit of acoustics circuit is power supply with the button cell, also comprises triode Q, capacitor C 1, C2, litmus and the music integrated chip that is connected with peripheral circuit.

This musical candle profile is similar to common candle, and it has adopted minimum electronic devices and components, low cost of manufacture, and dependable performance, pronunciation gives great volume, so easily accepted by people, has promotional value.

Fig. 2 is acoustics circuit figure.

B, c, e represent integrated base stage, collector electrode, emtting electrode respectively among the figure, by integrated requirement, and b, c, the corresponding triode (not shown) that connects of e.

Embodiment describes in further detail below in conjunction with accompanying drawing.

Musical candle (seeing Fig. 1-2) is made up of candle body portion and acoustics circuit.The candle body portion comprises the candle body (1) that is similar to common candle, the intravital candle wick (2) of lighting up is with general cotton system, two leads (6) enameled and cotton-covered wire or cotton covered wire of diameter phi 0.1～0.2mm, during making and candle wick (2) combine, owing to self have insulativity, so even the two wires contact is also harmless.

Acoustics circuit is a power supply with two button cells (5), litmus (4) is connected between positive source and standard music integrated chip (3) collector electrode, in order to prevent owing to litmus (4) self-excitation causes that sound is unclear, little capacitor C 1 at the two ends of litmus (4) one 0.01 μ F～0.02 μ F in parallel, the emtting electrode of trigger triode Q connects the trigger electrode of music integrated chip (3), its collector electrode connects positive source, and the lead (6) of two enameled and cotton-covered wire systems is connected on respectively between the base stage A and collector electrode B of triode Q, in flame, become the principle of conductor according to air, after lighting, candle just is equivalent between collector electrode and base stage, connect a resistance, make the Q conducting, music integrated chip (3) is triggered.Fray-out of flame, resistance disappears, and triode Q ends, and stops to trigger musical film.Simultaneously, trigger, should between the base stage of triode Q and ground, connect the little capacitor C 2 of a 200pF～500pF for preventing static.

Whole musical candle quiescent current is less than 0.1 μ A, and working current reaches 10～20mA, thus not only the shelf-time long, and give great volume.

Components and parts in the acoustics circuit are packaged in the candle bottom, and litmus (4) places candle body (1) the lowest, exposes sound hole, promptly becomes musical candle.

Claims

1, a kind of musical candle, form by candle body portion and acoustics circuit, the candle body portion comprises candle body (1), the intravital candle wick (2) of lighting up, two leads (6), it is characterized in that described acoustics circuit is a power supply with button cell (5), litmus (4) is connected between positive source and integrated (3) collector electrode of sound equipment, the two ends shunt capacitance C1 of litmus, the emtting electrode of trigger triode Q connects the trigger electrode of music integrated chip (3), collector electrode connects positive source, two thoroughly do away with edge leads (6) is connected on respectively between the base stage A and collector electrode B of triode Q, and inserts capacitor C 2 between the base stage of triode Q and ground.

2, musical candle as claimed in claim 1 is characterized in that two eradication edge leads (6) are enameled and cotton-covered wire or cotton covered wire.
