Publication number: 20060104471Abstract: A headphone apparatus the acoustic characteristics of which can be easily changed in accordance with the type of content the user wants to listen to. An adjusting knob provided on the housing of the headphone apparatus is moved, closing an opening made in a baffle. As a result, an acoustic space defined by the inner side of the baffle and an ear pad is more closed, thus increasing the level of low-frequency components of the sound generated by a sound-generating unit. Hence, the acoustic characteristics of the apparatus can be easily changed as the user desires.Type: ApplicationFiled: October 18, 2005Publication date: May 18, 2006Applicant: Sony CorporationInventors: Naotaka Tsunoda, Keitaro Fujiwara
