Ukulele

A ukulele, comprising a ukulele main body, the ukulele main body comprising a head, strings, a fret board and a body, a front surface of the body being provided with a saddle and a bridge;

• wherein the ukulele further comprises a circuit board, the circuit board being disposed in the body;
• the circuit board being provided with a power supply module, a Bluetooth audio input module, a pickup module, a mixing module, and an audio output module;
• the power supply module supplying power to the Bluetooth audio input module, the mixing module and the audio output module, the Bluetooth audio input module and the pickup module being connected with two input ends of the mixing module respectively, an output end of the mixing module being connected with the audio output module;
• the pickup module including a piezoelectric pickup, the piezoelectric pickup being disposed between the saddle and the bridge that are spaced from each other to collect an audio signal generated by the strings;
• the audio output module including an earphone socket and an audio socket, an amplifying circuit being provided between the earphone socket and the mixing module, the earphone socket and the audio socket being disposed on one side of the body;
• a tone adjustment potentiometer and a volume adjustment potentiometer being connected between the pickup module and the mixing module, the tone adjustment potentiometer and the volume adjustment potentiometer being respectively provided with knobs that are disposed on the front surface of the body;
• the piezoelectric pickup of the pickup module that is disposed between the saddle and the bridge collecting an audio signal generated by the strings, the Bluetooth audio input module adapted to receive an external audio signal, wherein the Bluetooth audio input module that receives an external audio signal supplies a first audio signal corresponding to the external audio signal to the mixing module and the pickup module that collects the audio signal generated by the strings generates a second audio signal corresponding to the audio signal generated by the strings to the mixing module, so that the mixing module to which the pickup module and the Bluetooth audio input module are connected mixes the second audio signal that corresponds to the audio signal generated by the strings with the first audio signal that corresponds to the external audio signal received through the Bluetooth audio input module to form a third audio signal that is outputted through the audio output module.
