 Newer canalphones can be driven by the less powerful outputs found on portable music players . Design variety Signal cables (analog audio, speaker, digital audio etc.) are used to link these components. There are also a variety of accessories, including equipment racks, power conditioners, devices to reduce or control vibration, record cleaners, anti-static devices, phonograph needle cleaners, reverberation reducing devices such as speaker pads and stands, sound absorbent foam, and soundproofing.
