Today audio electronic components play a vital role in consumer electronics. Nowadays audio systems can be found in cars, living rooms, offices or in mobile systems which accompany us, for example playing MP3 music, when we are on our way to work, jogging or waiting for a bus. What was once a rare good, such as a gramophone or a gramophone disc, is today an electronic means of mass consumption.

 

A widely spread audio component is the audio amplifier which uses a small amount of energy to control a larger amount of energy. Today, amplifiers are electronic. Electronics speakers, such as stereo speakers, are electromechanical transducers. They convert electrical signals into sound. Subwoofer speakers are special types of loudspeakers. They are used for reproducing bass frequencies. Speakers electronics devices are also found in the automotive industry. Car audio electronics are an important market in today’s automobile scene: Besides traditional radios, electronics for car audio systems are included in DVD and CD players. However, before a sound can be amplified or transmitted by a loudspeaker, a microphone is required in most cases. It is a transducer device used for the conversion of sound into an electrical signal. Microphones are not only found on stages or in record studios, but also in our everyday lives, for example in telephones, hearing aids, tape recorders or in computers. Nine volt audio electronic devices are, for example fire detectors or digital and alarm clocks. 9 Volt batteries are commonly used as backup electrical supply in these appliances.

 

Especially in consumer audio electronics there have been lots of shifts in the past years. When tape recording and a walkman were the trends in the 1980s, small and stylish MP3 players and digital music files are today musts in the consumer market. In addition to the CD, there are mini discs and DVDs. Product innovation cycles have become shorter and shorter. Once, a consumer electronics device is marketed, technological progress leads, for example in the field of semiconductor technologies, to the rapid design and manufacturing of follow-up models. But planned obsolescence also leads to great amounts of electronic waste. Consumers show that the more stylish and small devices are, the more requested they are. Products which are easy to use and dispose of a high level of automation are strongly requested. Global audio electronic supply management and increasing competition create ever falling prices in the consumer electronics sector.
