As a speaker design and technical management personnel, and sometimes feel that the speaker although only a dozen small parts, but the degree of complexity troublesome than we imagine. This is because: energy conversion devices commonly encountered usually only once. Such as motor is to convert electrical energy into mechanical energy, light energy is converted [...]

Recently, a client mentioned on the buzzer, speaker of the PA cavity why the overall impact of such a big sound reasons, as follows:
We know that buzzer, speaker of the PA cavity design, is often understood as follows:
1: to have sound chamber, from the PA with, as to why should tone chamber, not sure.
2: Sealing [...]

8 ohm speaker impedance frequency
8 ohm speaker arising from the resonance in the 400Hz, its resistance increased from 8 ohms to 10 ohms, at 10KHz, its resistance began to increase, to 1MHz, 100 ohms. In the absence of the audio signal, the final output is a symmetrical square wave, although speaker impedance of 100 ohms, [...]

Speaker frequency response curve
Speaker frequency response curve, which is a record in the width of 5cm or lOcm irregular curve of the continuous recording paper.
X-axis represents the input signal frequency of the speaker unit;
Y axis represents the measured loudspeaker signals at different frequencies when the sound pressure level generated.
We the human ear can hear the [...]
