PURPOSE: A speaker suspension outputs good quality of sound when the peak voltage electric signal of a wideband acoustic signal in a broadband is applied to a voice coil. CONSTITUTION: A speaker suspension comprises a swing bridge (100). The swing bridge is connected to a voice coil (4) to be able to apply an electric current in order to apply an electric signal to the voice coil from the outside. The swing bridge vibrates the voice coil in the longitudinal direction of a permanent magnet through the electromagnetic induction of the electric signal applied to the voice coil. The swing bridge is attached to a space between a vibration plate and the voice coil in order to vibrate the vibration plate with the vibration of the voice coil. Bothe ends of the swing bridge are supplied with electrical signals. The swing bridge electrically connects the lead-in line of the voice coil to the lead-out line of the voice coil by separately soldering the lines. The swing bridge includes a first bridge (110) and a second bridge (120). Both ends of the first bridge are integrated with a positive terminal. The first bridge is connected to the lead-in line of the voice coil. Both ends of the second bridge are integrated with a negative terminal. The second bridge is connected to the lead-out line of the voice coil. |
