A paper cone speaker unit has no voice coil and is not connected to a power source, so it can only be measured indirectly. This method is similar to the way a passive radiator is tested.
When the paper cone speaker unit reaches its resonant frequency, the vibration amplitude of the unit itself becomes the largest. This is the same concept as a speaker reaching its maximum vibration amplitude at its resonant frequency.

The following lists many requirements of electroacoustic transducers , but according to the principle of electroacoustics , it is impossible to meet all the requirements. Some demands are mutually exclusive and conflicting with each other, and electro-acoustic engineers need to choose between the ebb and flow of each other's factors. This means that electro-acoustic is not only an engineering discipline, but also an endless craft art.
