Claims (9)
- Mobiltelefon-Lautsprecher mit einem Dauermagneten (1), einer Membran (3), einer ersten elektrischen Spule (2) mit mechanischer Erregung, die in bezug auf den Magneten beweglich und an der Membran befestigt ist, und einer zweiten elektrischen Spule (6; 9), dadurch gekennzeichnet, daß die zweite Spule (6; 9) mit der ersten Spule (2) derart in Reihe gewickelt ist, daß sie eine gegenelektromotorische Kraft erzeugt, die derjenigen entgegengerichtet ist, die von der ersten Spule erzeugt wird, wenn sie beide dem gleichen zeitlich veränderlichen elektromagnetischen oder magnetischen Feld unterworfen sind, und daß die zweite Spule (6; 9) in bezug auf den Magneten ortsfest gehalten wird.
- Lautsprecher nach Anspruch 1, dadurch gekennzeichnet, daß die zweite Spule (6; 9) innerhalb des Felds des Magneten angeordnet ist.
- Lautsprecher nach einem der Ansprüche 1 bis 2, dadurch gekennzeichnet, daß die zweite Spule (6; 9) durch eine Gleitwand (19) mechanisch von der ersten Spule getrennt ist.
- Lautsprecher nach einem der Ansprüche 1 bis 2, dadurch gekennzeichnet, daß die zweite Spule (6; 9) außerhalb des Felds des Magneten angeordnet ist.
- Lautsprecher nach einem der Ansprüche 1 bis 4, dadurch gekennzeichnet, daß die zweite Spule (9) in die erste Spule (2) eingefügt ist, daß die erste und die zweite Spule je ein Paar von Versorgungsadern aufweisen, die nebeneinander münden, wobei das Adernpaar der ersten Spule an einem Ende dieser Spule entgegengesetzt zum Ende der zweiten Spule mündet, wo das Adernpaar dieser zweiten Spule mündet.
- Lautsprecher nach einem der Ansprüche 1 bis 5, dadurch gekennzeichnet, daß die Enden der Litzen der beiden Spulen auf die Membran geklebt sind.
- Lautsprecher nach einem der Ansprüche 1 bis 6, dadurch gekennzeichnet, daß die Enden der Litzen der beiden Spulen auf den Rücken der Membran geklebt sind.
