Description

music candle

本实用新型涉及一种音乐蜡烛，其最好但不限于放在庆祝生日或其它庆祝活动的蛋糕上。The utility model relates to a musical candle, which is preferably but not limited to be placed on cakes celebrating birthdays or other celebrations.

众所周知，在生日会上，蜡烛首先被点燃，然后，由主角吹熄蜡烛。此时，通常由宾客唱大家熟知的“祝你生日快乐”歌。而在其它庆祝场合则需要有其它歌曲或乐曲相适合。但是，如果蜡烛能够在点燃的同时自动播放音乐来描述声调、乐曲或“生日快乐”歌等，进而渲染、烘托气氛，定会倍受人们的喜爱。We all know that at a birthday party, the candles are lit first, and then the main character blows out the candles. At this time, the well-known "Happy Birthday to You" song is usually sung by the guests. On other celebratory occasions, other songs or pieces of music are required. However, if the candle can automatically play music to describe the tone, music or "Happy Birthday" song etc. when lit, and then render and set off the atmosphere, it will be loved by people.

因此，本实用新型的目的在于提供一种音乐蜡烛，当它被点燃时，它同时放出预存的乐曲，例如“生日快乐”歌。Therefore, the purpose of this utility model is to provide a kind of musical candle, when it is lit, it emits the melody of pre-stored at the same time, for example " happy birthday " song.

为了到达上述目的，本实用新型提供了一种音乐蜡烛，该音乐蜡烛包括具有烛芯的蜡烛体、支承蜡烛体的烛座和设置在烛座中的电路，该电路包括：电池；扬声器；具有预存代表声音信号的脉冲的存储器和放大器的电路，放大器与扬声器相连；与电池串联的降压电阻；以及由蜡烛体中延伸出来、在所述蜡烛火焰的热作用下使电路接通的导线，该导线包括热敏元件和压电元件，该热敏元件包括一对电极，分别与存储器和电池相连接，压电元件可产生电压，该电压通过两个电极施加于存储器，并触发存储器释放代表声音信号的预存脉冲信号，使声音通过扬声器再现出来。其中，所述导线穿过烛芯延伸，或者沿烛芯外侧延伸。In order to achieve the above object, the utility model provides a musical candle, which includes a candle body with a wick, a candle holder supporting the candle body and a circuit arranged in the candle holder, the circuit comprising: a battery; a loudspeaker; A memory for pre-storing pulses representing a sound signal and a circuit for an amplifier connected to a loudspeaker; a drop resistor connected in series with the battery; and a wire extending from the body of the candle to complete the circuit under the heat of the flame of said candle, The wire includes a thermosensitive element and a piezoelectric element, the thermosensitive element includes a pair of electrodes, respectively connected to the memory and the battery, the piezoelectric element can generate a voltage, the voltage is applied to the memory through the two electrodes, and triggers the memory to release the representative The pre-stored pulse signal of the sound signal enables the sound to be reproduced through the loudspeaker. Wherein, the wire extends through the candle wick, or extends along the outside of the candle wick.

下面将参照附图通过举例的方式对本实用新型的实施例进行详细描述。Embodiments of the present utility model will be described in detail below by way of examples with reference to the accompanying drawings.

图1为蜡烛的侧视图；Fig. 1 is the side view of candle;

图2为可用于本实用新型的电路框图。Fig. 2 is a circuit block diagram that can be used in the utility model.

图3为用于本实用新型的具体电路图。Fig. 3 is a specific circuit diagram for the utility model.

如图1所示，按照本实用新型的蜡烛1包括：圆柱状的普通蜡烛体2，它包含位于其中央烛芯3。蜡烛体2以烛套5支承，烛套5连接于烛座4。在邻近于烛芯3的位置处设有一对细导线6，导线6包括热敏元件6A和压电元件6B，它们在蜡烛体2内沿着蜡烛的整个长度延伸，并与设置在烛座4内的电路50相连。As shown in Fig. 1, a candle 1 according to the present invention comprises: a cylindrical ordinary candle body 2, which contains a wick 3 in its center. The candle body 2 is supported by a candle holder 5 , and the candle holder 5 is connected to the candle holder 4 . A pair of thin wires 6 are arranged at a position adjacent to the candle wick 3. The wires 6 include a thermosensitive element 6A and a piezoelectric element 6B. They extend along the entire length of the candle in the candle body 2 and are arranged on the candle holder 4. The circuit 50 inside is connected.

如图2和3所示，设置于烛座4内的电路50以电池56作为电源。电路50包括由存储器64和与之相连的放大器66构成的电路，放大器66用于驱动扬声器58。由电池供电的降压电阻68与存储器64并联。热敏元件6A与降压电阻68串联，热敏元件6A的电极28通过输入导线70与存储器64相连，而另一电极30与电池56和地线72相连。一旦受到机械应力作用，压电元件6B便产生电压，该电压通过电极28和30施加于存储器64，进而触发存储器释放代表声音信号的预存脉冲信号，使声音经放大器放大后通过扬声器再现出来。As shown in FIGS. 2 and 3 , the circuit 50 disposed in the candle holder 4 is powered by a battery 56 . The circuit 50 includes a circuit consisting of a memory 64 connected thereto to an amplifier 66 for driving a speaker 58 . A drop resistor 68 powered by a battery is connected in parallel with the memory 64 . The thermosensitive element 6A is connected in series with the dropping resistor 68 , the electrode 28 of the thermosensitive element 6A is connected to the memory 64 through the input wire 70 , and the other electrode 30 is connected to the battery 56 and the ground wire 72 . Once subjected to mechanical stress, the piezoelectric element 6B generates a voltage, which is applied to the memory 64 through the electrodes 28 and 30, and then triggers the memory to release the pre-stored pulse signal representing the sound signal, so that the sound is amplified by the amplifier and reproduced through the speaker.

当烛芯3被点燃时，导线6可导电，并触发烛座4中的电路，以再现存储在存储器中的乐曲。电路由电池供能，乐曲通过放大器被放大，声音通过烛座4上的孔7被播放出来。When the wick 3 is lit, the wire 6 can conduct electricity and trigger the circuit in the candle holder 4 to reproduce the melody stored in the memory. The circuit is powered by a battery, the music is amplified through the amplifier, and the sound is played through the hole 7 on the candle holder 4 .

如上所述，乐曲可以是“生日快乐”歌，电可以是其它适当的乐曲。As mentioned above, the melody may be the "Happy Birthday" song and the song may be other suitable melodies.

当蜡烛熄灭时，可用机械方法，例如用剪刀剪断导线6，使导线6终止导电，乐曲便随之停止。When the candle was extinguished, available mechanical means, such as cutting the wire 6 with scissors, made the wire 6 terminate the conduction, and the music stopped thereupon.

此外，尽管蜡烛一词通常被用来描述适于装饰蛋糕等的细长蜡烛，但本实用新型同样可适用于其它类型的蜡烛，甚至夜晚照明灯，使其可选择播放摇篮曲。Furthermore, although the term candle is generally used to describe a slender candle suitable for decorating cakes etc., the present invention is equally applicable to other types of candles, and even night lights with the option to play a lullaby.
