Abstract

The invention discloses a dynamic speaker with a magnet system. The dynamic loudspeaker driver (1a) comprises a magnet-system; a membrane (3); the membrane being movably mounted with respect to the magnet-system; at least one voice coil (2) attached to the membrane (3) and operatively coupled with the magnet-system; at least one figure 8-shaped coil (9A) attached to the membrane (3) and to a lateral surface of the at least one voice coil (2).

Description

technical field [0001] The present invention relates to a dynamic speaker driver, a speaker comprising the dynamic speaker driver, and a mobile device such as a mobile phone comprising the speaker. [0002] The invention also relates to a method of making a loudspeaker driver. Background technique [0003] Dynamic loudspeaker drivers generally include a magnetic circuit, a diaphragm movably mounted relative to the magnetic circuit, and a voice coil engaged with the diaphragm. The magnetic circuit system includes a magnet, and the voice coil is operatively coupled to the magnet. Generally speaking, a loudspeaker includes an enclosure and at least one dynamic speaker driver mounted in the enclosure. [0004] In operation, an electrical signal is applied to the voice coil, for example via an amplifier. The diaphragm is then moved relative to the magnetic system and relative to the housing under the electrical signal, thereby moving the air. The sound pressure level of a lou...
