Abstract
A loud-speaker for car has improved sound reproduction. It has high fidelity performance. The loud-speaker has a frequency pass band of 5,000 to 40.000 Hertz. It is used in addition to the existing loud-speaker in the car. It can be connected across the terminals of the existing loud-speaker. The loud-speaker comprises a cardboard or plastic case (A). The case (A) has a face (C) with adhesive for fixing onto the dash board of the car. There is a a loud-speaker proper (B) with flying leads and a capacitor (E). The capacitor (E) is used to maintain the load impedance of the car radio the same as with no additional loud-speaker. The loud-speaker has a power of 20 Watt It may be used for stereo or quadraphonic sound.
