发明名称 Enclosure for sound reproduction devices
摘要 The enclosure (2c) consists of a fine ceramic material with a water absorption of 8-10% measured in accordance with DIN 51065. It has an asymmetric structure and is preferably provided with relief structures (2c). The characteristics of the fine ceramic material with respect to distortion and vibration characteristics are equivalent to those of wood and plastic. More complicated spatial shapes for further improvement of these technical characteristics can be produced particularly simply and inexpensively using the methods typical of such ceramic materials. <IMAGE>
