| 摘要 |
The present invention relates to an adaptive maximum power control apparatus, and to the invention in which the maximum power delivered to an acoustic signal playing apparatus is not influenced by the intrinsic impedance value change of the acoustic signal playing apparatus, and is identically delivered. Accordingly, disclosed is the adaptive maximum power control apparatus comprising: a connection sensing means sensing the connection of an external device; an impedance calculating means calculating the impedance value of the external device based on the sensing of the external device with the predetermined calculus; and a controlling means generating a signal which controls a gain for the maximum power value delivered to the external device to be presumed as the predetermined value based on the impedance value. |
