The Mystery of Two-Type Speakers: Will It Work?

In summary: If the speaker is connected to an output of the amplifier that is not connected to an AC source, then the speaker will not work.

I have uploaded the pic of schematic of two type speaker. The left side of pic shows the usual one speaker where sighnals are fed at both the wire of the coil.

1) I assume the right side of the pic(speaker)(which I imagine) should work , where I have grounded one of the coil and ths signal is fed into other. I am confused shall it work .

2) If it works, how shall I ground the wire?

Moving coil speakers should not have DC voltage across the coil. This causes the speaker cone to move towards one end of its travel and this may limit the audio available from the speaker and could cause distortion.

So, if your speaker has a capacitor in series with it, inside the amplifier, it is OK to ground the other side of the speaker.

In some circuits, the speaker is placed between two outputs of an amplifier and neither side is grounded.

Just follow the markings on the amplifier. These will tell you how to connect the speaker to the amplifier.

Sir , for now I am not taking amplifier into account. Actually I was going to desighn very simple paper cup speaker.
I searched all over interne , saw sighnal fed into both side of the wire?

What woul be effect of one side ground actually?

It doesn't matter if the speaker is grounded.

If one side of the speaker is grounded and one side of the amplifier output is grounded, then these points are considered as joined together.

There just has to be an AC signal reaching the two input connections of the speaker.
 

FAQ: The Mystery of Two-Type Speakers: Will It Work?

How do two-type speakers work?

Two-type speakers, also known as bi-amplified speakers, work by dividing the audio signal into two separate frequency ranges. Each frequency range is then amplified by its own dedicated amplifier and sent to a separate speaker driver. This allows for better control and accuracy in reproducing sound, resulting in improved overall sound quality.

What are the benefits of using two-type speakers?

Two-type speakers offer several benefits, including improved sound quality, increased power handling, and better control over sound reproduction. By separating the audio signal into two frequency ranges, each driver can focus on reproducing a specific range of frequencies, resulting in clearer and more accurate sound.

3. Can I use any type of amplifier with two-type speakers?

Yes, you can use any type of amplifier with two-type speakers as long as it has the appropriate power output for the speakers. However, using a dedicated bi-amplifier or an amplifier with a bi-amping feature can provide better results as they are specifically designed for this type of speaker setup.

4. Are two-type speakers suitable for all types of audio systems?

Two-type speakers can be used in a variety of audio systems, such as home theater systems, studio monitors, and even car audio systems. However, they may not be necessary or suitable for all setups. It is best to consult with a professional or do thorough research to determine if two-type speakers are the right choice for your specific audio system.

5. Do I need to use a crossover with two-type speakers?

Yes, a crossover is an essential component in a two-type speaker setup. It is responsible for dividing the audio signal into two frequency ranges and sending them to the appropriate speaker driver. Without a crossover, the speakers would not be able to accurately reproduce sound, and the overall sound quality would be greatly compromised.
