Here are 6 working modes to enable the professional portable speaker amplifier protection function:
1. Overcurrent protection
When the load of the portable speaker amplifier is too low but does not reach the short-circuit state, the short-circuit protection will not act at this time, but the output current will be very large and exceed the safe use value of the portable speaker amplifier. At this time, the overcurrent protection circuit will intervene in the work. The usual practice is: Control the input voltage and output current so that the power amplifier always works within a safe range.
2. Overheating protection
The well-designed amplifier will not have overheating protection under normal use. It will only act when the external use environment is bad or the internal failure occurs. The hottest part of the whole portable speaker amplifier is the C pole (collector) of the output stage transistor, so the temperature sensor for overheating protection is generally installed in the place closest to the C pole of the transistor or the hottest place on the radiator. The threshold value of overheating protection is generally 95°C, but also 105°C, and the extreme temperature of the transistor is 105°C.
3. Soft start protection value
Audio equipment with a large current draw can flow 4-10 times the average current value at the moment when the power is turned on. This is a shock to the power grid and the equipment itself, and will damage the equipment in severe cases. The soft-start circuit can suppress the inrush of current at the moment when the equipment is switched on and off, so that it can reach normal smoothly to protect the equipment and not cause grid fluctuations. This function is usually achieved with the negative temperature characteristic of the thermistor (NTC).
4. DC protection
When the portable speaker amplifier output stage is damaged or the static bias is shifted, it is possible to deliver a DC signal. For the speaker, its working method only produces impedance to the AC signal, and it does not produce any impedance (equal to zero impedance) for the DC signal. At this time, the current is infinite, so the coil of the speaker is equivalent to a DC signal. A heating wire will burn quickly. So accurate and fast DC protection circuit is very important. The DC protection start value of the portable speaker amplifier is usually set at 2V. When it is greater than or equal to this value, the portable speaker amplifier will cut off the output to protect the speaker. There are also amplifiers that will cut off the output by blowing the built-in DC fuse.
If the DC protection circuit of a portable speaker amplifier is normal, but the coil of the speaker is burned out, there are only two reasons: the power input to the speaker is too large, or the signal output by the portable speaker amplifier is clipped into a square wave.
Short circuit protection
When the output of the portable speaker amplifier is short-circuited for some reason, the current output by the portable speaker amplifier will circulate in its own circuit and become infinite. Such a situation is very dangerous, so there must be accurate and fast short circuit protection circuits to protect the best portable speaker amplifier equipment. Under normal circumstances, when a short circuit occurs in the portable speaker amplifier, first it will control the input signal to reduce its amplitude even to zero. If the situation does not improve (the current flowing through the best portable speaker amplifier still exceeds the safe value), it will suppress the output current, allowing The current flowing inside the amplifier is always lower than the safe value of the output stage transistors.
5. Distortion Compressor
The input level value of audio equipment has a specified range. If it exceeds this range, the signal will be clipped, and in severe cases, it will become a square wave. The function of the distortion limiter is to ensure that the level of the input signal is always controlled within the linear working area allowed by the audio equipment. The general standard is to start when THD1%.
