| 11. | The last character denotes the magnet / voice coil size, and directly influences the power rating.
|
| 12. | In 2002, Meyer Sound produced the SB-2, a horn with a throat and a voice coil.
|
| 13. | Planar magnetic speakers consist of a flexible membrane with a voice coil printed or mounted on it.
|
| 14. | Four years later, in 1915, they built a dynamic loudspeaker with a voice coil, a corrugated G.
|
| 15. | The purpose of the cone / surround assembly is to accurately reproduce the voice coil signal waveform.
|
| 16. | The arm is moved using a voice coil actuator or in some older designs a stepper motor.
|
| 17. | In loudspeakers, thermal capacities of the voice coils and magnet structures largely determine continuous power handling ratings.
|
| 18. | This is due to Morel's own, super-secret audio technology, cryptically called EVC ( external voice coil ).
|
| 19. | In the earliest loudspeakers, voice coils were wound onto paper bobbins, which was appropriate for modest power levels.
|
| 20. | More technically, the phone's speaker has to have a voice coil that generates a relatively strong electromagnetic field.
