1. Taboo power overload phenomenon
Usually when the wireless bluetooth speakers is equipped with a power amplifier, in order to make the performance of the wireless bluetooth speakers fully play, the power of the power amplifier is often larger than the power of the wireless bluetooth speakers, sometimes it is about 1 times larger.
In this case, in actual use, control the signal to the power amplifier not to be too large, the wireless bluetooth speakers will have a good performance, the sound is full, and the distortion is small. However, if you do not pay attention to the control signal and the signal input to the power amplifier is too large, the output power of the power amplifier will exceed the power that the wireless bluetooth speakers can withstand. For wireless bluetooth speakers, this is an overload phenomenon. Short-term overload has little effect on the wireless bluetooth speakers, but if the is overloaded for a long time, even if the wireless bluetooth speakers in the wireless bluetooth speaker does not burn, mechanical damage may occur. For example: the folding ring of the paper cone of the woofer is broken, the paper cone is broken, the lead wire of the voice coil is torn, the diaphragm of the tweeter is broken, etc. Therefore, if the power amplifier wireless bluetooth speakerused is more than 50% higher than the power of the wireless bluetooth speakers, you need to pay special attention to the signal size when using it, and try to control the use of the power amplifier in a state where the red light does not flash.
2. Frequency response, a hidden danger that affects the safety of wireless bluetooth speakers.
For example, a 15-inch full-frequency wireless bluetooth speaker has a frequency response range of 60-18kHz, which tells you that the electrical signal in this range can be restored to sound normally. Note that its lower limit frequency is 60Hz, and electrical signals below 60Hz cannot be converted into sound normally. If the electrical signal you input to it is a full-range signal without any processing, including components below 60 Hz. However, the energy of this part of the electrical signal by the wireless bluetooth speaker cannot be converted into sound. This part of the electrical energy is basically converted into heat, which is a hidden danger.
If the wireless bluetooth speaker works with high power input for a long time, the heat will cause the temperature of the voice coil to continue to rise, causing the glue that fixes the coil to melt, and the loose coil of the voice coil is damaged. If you don't realize this problem, even if the wireless bluetooth speaker is repaired, it will be broken again in the future.
Solution: Use the filter (HPF) and (LOW CUT) on the processor or other equipment to cut off the low frequency part that the wireless bluetooth speaker cannot express. The same is true for the high frequency part above 18KHz, which should be cut off by the filter of the processor.
So, how to make the wireless bluetooth speakers have a longer service life? Let's take a look!
1. The normal working temperature of sound equipment should be 18℃~45℃. Too low a temperature will reduce the flexibility of some machines (such as tube machines); too high a temperature will easily burn out the components, or cause the components to age prematurely. In summer, pay special attention to cooling and maintain air circulation.
2. Avoid direct sunlight on sound equipment, and prevent it from getting close to heat sources, such as heaters.
3. After the sound equipment is used up, the function keys should be reset. If the function key is not reset for a long time, and the torsion spring is in a stressed state for a long time, it is easy to malfunction.
4. Before switching on and off the sound power, turn the volume potential of the power amplifier to the minimum. This is the most effective way to maintain power amplifiers and wireless bluetooth speakers. At this time, the power amplification of the power amplifier is almost zero, and at least it will not cause harm to the wireless bluetooth speakers during misoperation.
5. Turn on from front to back when turning on, that is, turn on the CD player first, and then turn on the front and rear stages. Turn the volume potentiometer of the power amplifier to the minimum when turning on. When shutting down, turn off the power amplifier first, so that the amplification function of the power amplifier is completely turned off. At this time, when the front-end equipment is turned off, no matter how large the inrush current is generated, it will not affect the power amplifier and wireless bluetooth speakers.
6. The machine should be used frequently. It can prolong the life of the machine, such as some parts with motors (recording stand, laser disc player, laser video disc player, etc.). If it does not rotate for a long time, some parts of the machine will be deformed.
7. Power on regularly. In situations where it will not be used for a long time, especially in humid and high temperature periods, it is best to power on for half an hour a day. In this way, the heat generated by the internal components of the machine can be used to drive away moisture and prevent internal coils, wireless bluetooth speaker voice coils, transformers, etc. from being damp and moldy.
8. Wipe the surface of the machine with a clean, moist, soft cotton cloth at regular intervals; when not in use, cover the machine with a dust cover or a cover cloth to prevent dust from entering.
