SPEAKER SYSTEM HAVING IMPROVED RF IMMUNITY TO RF ELECTROMAGNETIC INTERFERENCE PRODUCED FROM MOBILE WIRELESS COMMUNICATIONS DEVICE |
摘要 |
A speaker system has improved immunity to RF electromagnetic interference produced from a mobile wireless communications device. A speaker housing is sized for desktop use with a personal computer. An audio transducer is carried by the speaker housing. A circuit board is carried by the speaker housing and has audio circuitry mounted thereon and operative with the audio transducer. The audio circuitry includes a power amplifier having left and right channel inputs for receiving an audio signal and amplifying the audio signal to the audio transducer.
