The role of the speaker is to convert electrical signals into sound signals, that is, to make the audio energy vibrate the cone or diaphragm and resonate (resonate) with the surrounding air through electromagnetic, piezoelectric or electrostatic effects, thereby making sound. The speaker is a key component in audio equipment, and its performance has a significant impact on the sound quality.
The working conditions of the speaker include the following aspects:
Power limit: The power of the speaker should not exceed its rated power, otherwise the voice coil may be burned or dispersed.
Impedance matching: The impedance of the speaker should match the output line to ensure normal operation.
Environmental layout: When arranging the speaker, ensure that the sound field is uniform and has sufficient sound level (3 meters above the ground). The electric horn speaker must be used after the sound head is put on the horn, otherwise it is easy to damage the sound head.
Phase problem: When two or more speakers are used together, you need to pay attention to the phase problem to ensure the synchronization and coordination of the sound.
Usage order: When using the amplifier, turn on the sound source first, then the amplifier. After use, turn it off in the opposite order to prevent the speaker from being subjected to instantaneous current surges.
Heat dissipation problem: The amplifier should be placed in a clean, dust-free, ventilated, and dry place. It is strictly forbidden to be exposed to rain. Pay attention to heat dissipation when using it in high temperature seasons
