Acoustic output processing apparatus
First Claim
1. An acoustic output processing apparatus comprising:
- an acoustic correction filter for correcting with emphasis a specific sound among sounds delivered to the filter from a microphone;
a selector having a correction output unit for delivering sounds received from an acoustic output device to the acoustic correction filter and a non-correction output unit for generating sounds received from an acoustic output device through a speaker without passing them through the acoustic correction filter, the selector delivering one of the received sounds through the correction output unit while delivering the other received sounds through the non-correction output unit;
device operation-mode detecting means for detecting an operation mode of an acoustic output device and detecting a present mode of acoustic output processing; and
an acoustic output processing control unit for performing operational control of acoustic output processing, including the control of the selector, by a factor corresponding to a result detected by the device operation-mode detecting means.

Abstract
Acoustic outputs from an audio system and various acoustic output devices are produced from a speaker, and a sound which a user desires to hear clearly is automatically selected and corrected with emphasis. A TV sound, an acoustic guide of a navigation system, and a sound on the other end of a hands-free device are delivered to a selector, and one of them is selected by a selector switching control and corrected by an acoustic correction filter to be produced. The other acoustic signals are produced as non-correction target signals together with an audio signal. An acoustic output processing control unit performs operational control of acoustic output processing corresponding to an operation mode of an acoustic output device and a present mode of acoustic output processing detected by device operation-mode detecting means while performing various operational function controls, including selector switching control and buzzer control, corresponding to data obtained by reading a memory in which modes of acoustic output processing are stored in advance.
