About ba:
The subwoofer must be matched well, and then installed into the box to make the phase inversion hole. Other parts shall be well sealed. Pay more attention to the speaker impedance, mouth meridian and height. If the impedance and mouth meridian are not consistent with its note stroke, it will not be enough. Not only the sound is small, but also there is no shaking of the subwoofer
The same board is compared with the following two speakers, both of which are 4 Euro: the sound on the left is also 4 euro, which is not only very small, but also very poor sound quality; The one on the right performs very well in all aspect
This product can drive 5V / 20W (W), based on the principle of circuit, the secondary development and proceing, the maximum power can be configured to 20W [10W ba + 10W sub box (5W * 2)]; so the power amplifier board has strict requirements for power supply and horn,
Selection requirements:
Power requirements: DC Voltage 5V (4.8-5v), current more than 3A; (power line should also be able to pa such a large current; some power lines have such a large current, but the wire can not pa such a large current; secondly, mobile power should use the originaenuine manufacturers, and ensure the discharge capacity to meet the standard (because this kind of product is lithium battery through the way of boosting), Shanzhai not only can't keep up with the current, but also can't keep up with the constant current. In particular, its instantaneous current can't keep up with it (it can't drive or distort the sound) and it's easy to damage the board. Pay attention!!
