portable speaker system for stringed electric instruments

摘要

The present invention relates to a portable speaker system for a stringed electric instrument, such as a guitar. The portable speaker system has a case that includes an audio jack to receive a raw audio signal from a guitar, an amplifier, a speaker and a power source. The portable speaker system is secured to the guitar by a button connector, which removably attaches to a guitar docking knob, and a stabilizer to inhibit rotation of the portable speaker system when attached to the guitar. The portable speaker system generates, in a portable mode, a sound output from the raw audio signal. the portable speaker system may mate with a portable computing device which can process the raw audio signal and provide a complementary audio signal from which the portable speaker system can generate, in a portable mode, a sound output.
