Title: COMMUNICATION EQUIPMENT, VEHICLE-MOUNTED HANDS-FREE DEVICE AND SOUND OUTPUT DEVICE
Abstract:
A sound signal from a portable telephone (2) acquired by a communication interface unit (10) is processed by a hands-free engine (11) and an output level adjustment unit (12), and thereby the sound volume or sound quality of output sound outputted from a speaker (4) in response to the sound signal is adjusted. An adjustability determination unit (14) determines whether or not the sound volume or sound quality of the output sound outputted from the speaker (4) is adjustable to a set sound volume or set sound quality within the range of adjustment capability of the hands-free engine (11) and the output level adjustment unit (12).
