Abstract

An acoustic processing system for an electronic device includes: an equalizer processor which boosts or cuts a digital signal which has been subjected to an acoustic process for each of frequency components; a low-pass filter which extracts a low-range signal from the signal from the equalizer processor and outputs the signal; a high-pass filter which extracts a high-range signal from the signal from the equalizer processor and outputs the signal; a high-range compressor which compresses the high-range signal; an adder which adds the low-range signal and the compressed high-range signal; and aspeaker which outputs an acoustic sound in accordance with the signal after the addition.

Description

Technical field [0001] The present invention relates to a sound processing system for electronic equipment including mobile phones. In particular, the present invention relates to a sound processing system and method for electronic equipment, and a mobile phone terminal that increase the sound pressure and volume feel of the entire reproduced sound. This application claims priority based on Japanese Patent Application No. 2007-073413, and the disclosure of this application is described in this application file by reference. Background technique [0002] In the interior of electronic equipment including mobile phones, as audio equipment, from the viewpoint of installation space and power consumption, micro speakers or micro receivers with a diameter of several centimeters and a thickness of several millimeters are often installed. However, physical constraints such as the sound radiation area, front sealing capacity, rear sealing capacity, and sound hole area of ​​such a size-res...
