Abstract

The utility model relates to a candle, which comprises a candle body with a candle wick, a candle holder and a circuit positioned in the candle holder, wherein, the circuit comprises a battery, a loudspeaker, the circuit which is composed of a memory and an amplifier and a conducting wire which causes the circuit to be switched on under the action of flame heat of the candle. The conducting wire comprises a heat sensitive element and a piezoelectric element, and the heat sensitive element comprises a pair of electrodes which are respectively connected with the memory and the battery, the piezoelectric element can generate voltage, and the voltage is applied to the memory through two electrodes to trigger the memory to release the prestored pulse signal which represents sound signal, causing sound to be reproduced through loudspeaker after the sound is amplified by the amplifier.

Description

Musical candle

The utility model relates to a kind of musical candle, its preferably but be not limited to be placed on celebrate one's birthday or the cake of other celebration on.

As everyone knows, in birthday party, candle is at first lighted, and then, puts out candle by the leading role.At this moment, sing " happy birthday to you " song that everybody knows by guests usually.Celebrate that at other occasion then needs other song or melody fit.But, if candle can be play music automatically when lighting tone, melody or " happy birthday " song etc. are described, so play up, heighten atmosphere, liking of people extremely surely.

Therefore, the purpose of this utility model is to provide a kind of musical candle, and when it was lighted, it emitted the melody that prestores simultaneously, for example " happy birthday " song.

In order to arrive above-mentioned purpose, the utility model provides a kind of musical candle, and this musical candle comprises the candle socket of candle body with candle wick, supporting candle body and be arranged on circuit in the candle socket that this circuit comprises: battery; Loud speaker; Have the storer of pulse of the representative voice signal that prestores and the circuit of amplifier, amplifier links to each other with loud speaker; With the placed in-line voltage dropping resistor of battery; And by extending out, under the heat effect of described candle flame, make the anastomosing lead of circuit in the candle body, this lead comprises thermal sensing element and piezoelectric element, this thermal sensing element comprises pair of electrodes, be connected with battery with storer respectively, piezoelectric element can produce voltage, this voltage puts on storer by two electrodes, and the pulse signal that prestores of flip-flop storage release representative voice signal, and sound is come out by loudspeaker reproduction.Wherein, described lead passes candle wick and extends, and perhaps extends along the candle wick outside.

By way of example embodiment of the present utility model is described in detail below with reference to accompanying drawings.

Fig. 1 is the side-view of candle;

Fig. 2 is for can be used for circuit block diagram of the present utility model.

Fig. 3 is for being used for physical circuit figure of the present utility model.

As shown in Figure 1, comprise according to candle 1 of the present utility model: columned common candle body 2, it comprises and is positioned at its central candle wick 3.Candle body 2 is with 5 supportings of candle cover, and candle cover 5 is connected in candle socket 4.Be provided with a pair of thin wire 6 in the position that is adjacent to candle wick 3, lead 6 comprises thermal sensing element 6A and piezoelectric element 6B, and their whole length along candle in candle body 2 is extended, and links to each other with circuit 50 in being arranged on candle socket 4.

Shown in Fig. 2 and 3, be arranged at circuit 50 in the candle socket 4 with battery 56 as power supply.Circuit 50 comprises the circuit that is made of storer 64 and the amplifier 66 that is attached thereto, and amplifier 66 is used to drive loud speaker 58.Battery-powered voltage dropping resistor 68 is in parallel with storer 64.Thermal sensing element 6A connects with voltage dropping resistor 68, and the electrode 28 of thermal sensing element 6A links to each other with storer 64 by input lead 70, and another electrode 30 links to each other with ground wire 72 with battery 56.In case be subjected to the mechanical stress effect, piezoelectric element 6B just produces voltage, this voltage puts on storer 64 by electrode 28 and 30, and then the pulse signal that prestores of flip-flop storage release representative voice signal, and sound is come out by loudspeaker reproduction after amplifier amplifies.

When candle wick 3 was lighted, lead 6 can conduct electricity, and triggered the circuit in the candle socket 4, was stored in melody in the storer with reproduction.The electric routing battery energy supply, melody is exaggerated by amplifier, and sound is played out by the hole on the candle socket 47.

As mentioned above, melody can be " happy birthday " song, and electricity can be other suitable melody.

When candle extinguished, available mechanical means was for example cut off lead 6 with scissors, made lead 6 stop conduction, and melody just stops thereupon.

In addition, although candle one speech is used to describe the elongated candle that is suitable for decorating cake etc. usually, the utility model is equally applicable to the candle of other type, even the night lighting lamp, makes it can select to play lullaby.
