Specific embodiment
Embodiment one：
Referring to Fig.1, a kind of multi-functional middle sound box with sound, is provided with pronunciation unit 2 in its 1 front of cabinet, sets in 1 side of cabinet
It is equipped with power output socket, power output socket includes three-pin socket 5 and bipod socket 6 and USB interface 7, in addition in 1 side of cabinet
Face is additionally provided with switch button 4.
Referring to Fig. 2, mounting rack 8 is fixed in cabinet 1, mounting rack 8 has at least two slots 9, and slot 9 is for being inserted into
Secondary battery unit 10, secondary battery unit 10 have the connector 11 of plug-in type, and all secondary battery units 10 are by the way of in parallel
It links together to constitute charging cell module.In addition inverter circuit and USB driving circuit are additionally provided in cabinet 1.
Referring to Fig. 3, the power supply line of the charging end connection speaker of charging cell module, the discharge end connection of charging cell module
The input terminal of inverter circuit, the output end of inverter circuit connect AC outlet by switch button 4, USB driving circuit it is defeated
The discharge end and its output end for entering end connection charging cell module connect UBS interface 7.
In addition, the speaker further includes capacity prompt circuit, capacity prompt circuit includes voltage detecting circuit, single-chip microcontroller and shows
Display screen 3.As shown in figure 3, the discharge end of the input terminal connection charging cell module of voltage detecting circuit, the voltage detecting circuit
Output end connection single-chip microcontroller sampled signal input, the display screen 3 connects the I/O interface of single-chip microcontroller.
After the speaker connects working power, charging cell module obtains power supply from speaker power supply line to charge.Due to
Charging cell module is in such a way that multiple secondary battery units 10 are in parallel, therefore charging cell module holds with biggish electric energy
