At low frequency, a large diameter speaker moves with the entire surface area in phase. But at a specific frequency, dependent on the speed of sound in the membrane material and the diameter, the surface closest to the drive point and the outer edges of the surface starts to move out of phase. The speaker wobbles, creating distortion and decreased sonic output. So a large area speaker is by this reason less well suited for reproducing high frequency signals.
Also, a large speaker is heavy, and is harder to accelerate. This also limits the high frequency reproduction.
Adversely, a small area speaker needs to move far, have a high amplitude, to reproduce low frequency signals, creating Doppler distortion and unlinear reproduction.
One way to solve these problems is to divide the signal between two or more drivers of different sizes.
What else can I help you with?
Is the dimension of the frequency match the dimension of the force?
no ! dimensions of force and that of frequency are different.
How many sine waves does a loudspeaker produce in 1 second if its frequency is 256 Hertz?
256
If a frequency of a wave increases what will happen?
Increase decrease. The frequency MUST decrease.
A loudspeaker makes sounds by vibrating a cardboard cone what happens to the vibrations of the cone as the sound gets quieter?
As the sound gets quieter, the vibrations of the cardboard cone decrease in amplitude and frequency. This results in less movement of the cone, producing a softer sound.
If one dimension decrease will the others increase or decrease?
the others will follow along with the first therefore the others will decrease
What is the frequency range of the loudspeaker of the Lego Mindstorm NXTs Intelligent Brick?
About 14 to 15 feet. Forgive me if i am wrong
How does a decrease in velocity affect the frequency and wavelength of the waves entering the shallow water?
A decrease in velocity of the waves will cause a decrease in frequency and a decrease in wavelength as the waves enter shallow water. This is due to the relationship between velocity, frequency, and wavelength which is defined by the equation: velocity = frequency x wavelength.
What can you do to decrease the value of wavelength?
To decrease the value of wavelength, you can increase the frequency of the wave. This is because the wavelength and frequency of a wave are inversely related according to the wave equation: wavelength = speed of light / frequency. So, by increasing the frequency, you will effectively decrease the wavelength.
If a loudspeaker has a frequency of 120 Hz how often does it vibrate?
120 Hz means a vibration 120 cycles per second.
How does pressure affect frequency?
Pressure has a direct relationship with the speed of sound, which in turn affects the frequency of a wave. As pressure increases, the speed of sound increases. This causes the wavelength to decrease, resulting in an increase in frequency. Conversely, a decrease in pressure would lead to a decrease in frequency.
What is in a longitudinal wave?
When something vibrates, like a loudspeaker, it compresses the air and increases the pressure of the air when it moves out. When the loudspeaker moves in it creates a partial vacum and a decrease in air pressure. The increase/decrease in air pressure is propagated thru the air (or any medium),as a longitudinal wave, by pushing the air in front of it. The part of the cycle which produces the decrease in pressure is called a "rarefacation" of the air.
When does wave frequency decrease?
Wave frequency decreases when the wavelength of the wave increases. This means that less waves pass through a point in a given time, resulting in a decrease in frequency.
