Abstract
An electroacoustic driver includes a diaphragm, a diaphragm drive system and a diaphragm suspension. The diaphragm system is configured to subject the diaphragm to a motion, wherein the diaphragm suspension is configured to guide the diaphragm. The diaphragm drive system includes an active element configured to actively influence the motion of the diaphragm.
Claims32
An electroacoustic driver, comprising:
- a diaphragm;
- a diaphragm drive system configured to subject the diaphragm to a motion;
- and
- a diaphragm suspension configured to guide the diaphragm;
- wherein the diaphragm suspension comprises an active element and/or piezo electrical element configured to actively influence the motion of the diaphragm.
2 more elements
An electroacoustic driver, comprising:
- a diaphragm configured to move in a direction of a piston-like motion;
- and
- a surround formed along an edge region of the diaphragm so as to guide the diaphragm laterally and along the direction of the piston-like motion, wherein the surround is configured to actively excite the piston-like motion.
An electroacoustic driver, comprising:
- a diaphragm configured to move in a direction of a piston-like motion;
- a basket;
- a diaphragm drive system arranged between an edge region of the diaphragm and the basket, wherein the diaphragm drive system comprises one or more electrical devices which are configured to subject the diaphragm to a piston-like motion;
- and
- a diaphragm suspension configured to guide the diaphragm laterally and along the piston-like motion.
