Classification: CPC H | IPC H

Claim 12:
13. A method for a loudspeaker, comprising:
applying an electrical signal to a contact, wherein the contact is coupled to a first voice coil, a second voice coil, and a third voice coil;
translating the electrical signal into an acoustic signal using a first magnet and a second magnet; and
outputting the acoustic signal in a low-mid frequency range and a high frequency range,
wherein the electrical signal generates a first electromagnetic field (EMF) at the first voice coil, a second EMF at the second voice coil, and a third EMF at the third voice coil;
wherein the second magnet generates a second magnetic field which interacts with the second EMF to oscillate a second diaphragm coupled to the second voice coil; and
wherein the second magnetic field further interacts with the third EMF to oscillate a third diaphragm coupled to the third voice coil.
