Description

Technical Field

[0001] The utility model relates to the field of sound generators, in particular to an inverted sound generator. Background Art

[0002] A sound generator, also commonly known as a speaker or a sound device, is an electroacoustic transducer used in electronic devices, mainly used in sound-generating toy series. It is an important component of the sound-generating effect of electronic equipment. The main working principle of the sound generator is to use circuits and audio devices to produce sound. Specifically, when a button or switch on the toy is pressed, the circuit is closed and current begins to flow. The current is then transmitted to the audio device (usually a speaker), which converts the current into sound. The audio device usually consists of a vibrating membrane, a vibrating coil, and a magnet. When current passes through the vibrating coil, a magnetic field with a sound frequency is generated, which interacts with the magnet to cause the vibrating coil to begin to vibrate. The vibrating coil causes the vibrating membrane fixed on it to change, thereby producing sound.

[0003] Sound generators are widely used in various fields. In the field of toys, sound generators can be used as independent products or installed in other toys to expand their functions. The sound produced by the sound generator can effectively attract children's attention.

[0004] Existing sound generators usually require flipping a switch to turn on the circuit to make a preset sound, but the sound generator only makes one sound each time the switch is flipped, which is not direct enough for children to use repeatedly, and usually can only play one preset sound. It is not interesting enough, and the gameplay is not diverse enough, so it is very easy for children to lose interest in it. Utility Model Content
