Toy speakers, also known as "Mini Toy Speaker", are a very commonly used electro-acoustic transducer. Toy speakers are mainly used in the series of sound-emitting toys. For the sound-emitting effect of toys, it is one of the most important components.
The parameters of the toy speaker refer to the specific performance parameters of the speaker tested by the special speaker test system. The commonly used parameters mainly include: Z, Fo, η0, SPL, Qts, Qms, Qes, Vas, Mms, Cms, Sd, BL, Xmax, Gap gauss. That is, the resistance value of the speaker, DC impedance, minimum resonance frequency, sound pressure level, decibel, the total quality factor value of the speaker, etc.
