Rated Noise Power: Continuously input analog noise signal to the speaker for continuous operation within 100 hours without overheating and mechanical damage. This power is called the rated noise power of the speaker.
Maximum Sinusoidal power: This is a continuous sinusoidal signal that is sent to a single frequency in a given frequency band. It is sent to a single-frequency continuous sinusoidal signal and works continuously for one hour. At this power, the speaker's voice coil vibration should not produce a sound. The speaker has no overheating and mechanical damage.
Long-Term Power: This is a specially specified noise signal power in a given frequency band.
Short-Term Power: It is also a special kind of noise power, which is defined as the speaker working for 1 second, stopping 60 minutes and repeating 60 times. It does not cause permanent mechanical damage during this power.
Music Power: Depending on the ability to subject the speaker to short-term sinusoidal signals below 250 Hz, it does not sound noticeable and there is no permanent mechanical damage.
