METHOD, APPARATUS AND SYSTEM FOR SUPPLYING POWER TO ACTIVE NOISE CANCELLING EARPHONE

摘要

Embodiments of the present invention relate to the field of electronic products. Provided are a method, apparatus and system for supplying power to an active noise cancelling earphone, which can solve the problem of high complexity of operations in supplying power to the active noise cancelling earphone. The method for supplying power to an active noise cancelling earphone comprises: receiving a signal, transmitted by a terminal, of a first voltage; processing the signal of the first voltage to obtain a signal of a second voltage, the second voltage being lower than the first voltage; and transmitting the signal of the second voltage to a noise cancelling chip of the active noise cancelling earphone, so that the noise cancelling chip of the active noise cancelling earphone obtains the signal of the second voltage to achieve a noise cancelling function. The method, apparatus and system for supplying power to an active noise cancelling earphone provided in the embodiments of the present invention are used for supplying power to the active noise cancelling earphone.
