For this week, I design the casing to cover the circuit for make it's more smart and easy to carry. For each casing, I have to drill the hole for the input (power supply), audio input and output (speaker). After placing each circuit in the casing, I must check all the circuit if it's function or not because some mistake such as broken connecting wire or other than that.
Pictures below show the casing that I have used for the each circuit:
Figure 19: The complete circuit of Class B in the casing
Figure 20: The complete circuit of Class AB using TDA 2030 in the casing
Figure 21: The complete circuit of Class AB using TDA 2003 in the casing
For the Class D audio amplifier, I have some doing troubleshoot to know what the problem and it still does not work. A class D amplifier is basically a switching amplier or PMW amplifier. Efficiency of 90-95% are possible.
