Compared with the power supply part of the traditional network sound post in the figure 1, the power supply module 7 has the advantages of fewer used components, simpler circuit structure and convenience in maintenance, and can reduce the hardware cost due to the fact that some components are saved. In addition, the sixth resistor R6 is a current limiting resistor, and is used for current limiting protection of the collector current of the first diode Q2. The current limiting protection principle is as follows: when the collector current of the first diode Q2 is large, the sixth resistor R6 can reduce the collector current of the first diode Q2 to keep the first diode Q2 in a normal operating state, so that the device in the circuit is not burned out due to too large current, and the safety and reliability of the circuit are high. It should be noted that, in the present embodiment, the resistance of the sixth resistor R6 is 29k Ω. Of course, in practical applications, the resistance of the sixth resistor R6 may be increased or decreased according to specific situations.

The working principle of the power supply module 7 is as follows: the first inductor L1, the first capacitor C1 and the second capacitor C2 in the circuit form a low-power-consumption pi-type filter which can filter electromagnetic interference, the circuit is essentially a boost chopper, if the second triode Q2 is switched on and off, the output voltage higher than the input voltage can be obtained, and the duty ratio is required to be changed according to the input voltage. In the circuit, a first unijunction transistor V1 is adopted to form an oscillation circuit, the first unijunction transistor V1 generates oscillation to output a pulse signal, the pulse width of the pulse signal is a constant value, and the output pulse is sent to the base electrode of a second triode Q2 to enable the second triode Q2 to be switched on and off. Therefore, the on time of the second transistor Q2 is kept constant, and the off time is controlled to control the output voltage. In order to control the off-time of the second transistor Q2, the first transistor Q1 shunts the charging current of the third capacitor C3 through the second resistor R2, so as to prolong the charging time, i.e., the period, of the third capacitor C3. The output voltage is divided by the fourth resistor R4 and the fifth resistor R5, and the base electrode of the first triode Q1 is driven by the first diode D1 (voltage regulator tube), so that the output voltage is controlled, and the purpose of regulating the output voltage is achieved.

In this embodiment, the first transistor Q1 is an NPN transistor, and the second transistor Q2 is an NPN transistor. Certainly, in practical applications, the first transistor Q1 and the second transistor Q2 may both adopt PNP transistors, but the circuit structure is also changed accordingly.

In this embodiment, the power supply module 7 further includes a second diode D2, an anode of the second diode D2 is connected to an emitter of the second transistor Q2, and a cathode of the second diode D2 is connected to the other end of the third resistor R3. The second diode D2 is a current limiting diode for current limiting protection of the emitter current of the second transistor Q2. The current limiting protection principle is as follows: when the emitter current of the second triode Q2 is large, the second diode D2 can reduce the emitter current of the second triode Q2 to keep the second triode Q2 in a normal working state, so that the elements in the circuit are not burnt out due to too large current, and the safety and reliability of the circuit are further enhanced. It should be noted that in the present embodiment, the second diode D2 has a model number of S-272T. Of course, in practical applications, the second diode D2 may also be another type of diode with the same function.

In short, in this embodiment, compared with the power supply part of the conventional network sound post, the power supply module 7 has fewer used components, simpler circuit structure and convenient maintenance, and can reduce the hardware cost due to the saving of some components. In addition, since the power supply module 7 is provided with a current limiting resistor, the safety and reliability of the circuit are high.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
