They will either pull in or push out depending on the polarity of the DC voltage and remain stationary.

This is a bad idea as the DC resistance of the voice coil is much less than the AC impedance of the voice coil and it is possible to overheat and burn out the voice coil due to the much higher current the DC voltage can produce in the voice coil compared to the AC voltage that would drive the voice coil in normal operation.

How do close-circuit jacks work?

These jacks are used in audio systems to patch in a piece of outboard gear. When you plug in the cable, the circuit is interrupted and sent to the external gear. When you remove the cable, the circuit 'closes' and sends the signal on through. A headphone jack is a closed-circuit jack. When you plug in your headphones, the circuit to the internal speaker 'opens' and sound is sent only to the headphones. When you unplug them, the circuit to the speaker 'closes' and you hear sound through the speaker again.


Why does only one speaker on my Beats by Dr. Dre work?

You may have accidentally dislodged the circuit by hitting or vigorously shaking the headphones. This can result in one speaker not working.


How does circuit protection work in speaker selectors?

Circuit protection in speaker selectors typically involves components such as fuses, circuit breakers, or overload protection devices that are designed to interrupt the circuit in case of excessive current flow or a short circuit. These components help prevent damage to the selector and connected speakers by cutting off power in case of a fault, thereby protecting the system from potential electrical hazards.


What do a speaker do in a circuit?

The purpose of a speaker is to produce sound. With respect to the circuit, it uses up some power, which is provided by other parts of the circuit. The generic name for elements that are designed to consume power is "load".


What energy type do you use to create a circuit to operate a speaker?

Crating the Circuit alone would be electric energy and when the speaker is operating it would turn into sound energy.


Is every resistance load resistance?

No. Load resistance is the value of the element actually doing the work of the circuit it is connected to. A speaker connected to an amplifier is the load.


What does a speaker do in a circuit?

It converts electrical energy to sound energy.


What are the applications of squelch circuit in communications?

A squelch circuit turns off the audio input to the speaker when there is no radio signal being received. This stops the speaker from producing annoying noise when no radio signal is being received.

What causes radio speaker on drivers door not work?

Answer 1 - Non-funcional SpeakersThere could be one or more of several causes, a few of which that come to my mind follow: A connector plug between the radio and speaker has become loose or disconnected,Corrosion has developed on the metal contacts INSIDE one of the connectors in the circuit,The speaker has become defective or,The circuit INSIDE the radio has become defective.There could be other causes, but these are the major ones that I can think of at the moment. Good luck.
