Audio system output power controlling device i.e. portable device, for musical toy, has amplifier filtering and using set-point to automatically smooth variations of sound power, where set-point is used for modifying input signal power

The device has a mean power controller (1) for calculating mean power. A result obtained by the controller is used by a comparator (3) which establishes a set-point (111) for modification of an input signal power (100) based on a power limit stored in an audio system. An amplifier (5) filters and us...
