voice coil การใช้

• The central controller system vibrated the electromagnet like an audio-speaker voice coil.
• Rotary voice coils are widely employed in devices such as disk drives.
• A rotary voice coil is a rotational version of a solenoid.
• The voice coil and the magnet form a linear electric motor.
• Inaccurate reproduction of the voice coil signal results in acoustical distortion.
• Copper wire provides an easily manufactured, general purpose voice coil, at a reasonable cost.
• They block the power amplifier from taking maximum control over the voice coil motion.
• The voice coil is attached by adhesives to the back of the speaker cone.
• Level shifts caused by resistive heating of the voice coil are termed power compression.
• A second pole piece in turn surrounds the voice coil.
• The last character denotes the magnet / voice coil size, and directly influences the power rating.
• In 2002, Meyer Sound produced the SB-2, a horn with a throat and a voice coil.
• Planar magnetic speakers consist of a flexible membrane with a voice coil printed or mounted on it.
• Four years later, in 1915, they built a dynamic loudspeaker with a voice coil, a corrugated G.
• The purpose of the cone / surround assembly is to accurately reproduce the voice coil signal waveform.
• The arm is moved using a voice coil actuator or in some older designs a stepper motor.
• In loudspeakers, thermal capacities of the voice coils and magnet structures largely determine continuous power handling ratings.
• This is due to Morel's own, super-secret audio technology, cryptically called EVC ( external voice coil ).
• In the earliest loudspeakers, voice coils were wound onto paper bobbins, which was appropriate for modest power levels.
• More technically, the phone's speaker has to have a voice coil that generates a relatively strong electromagnetic field.
