Abstract
The utility model relates to a molded bluetooth sound box, which comprises a sound box enclosure, a circuit board and four speakers; wherein, the circuit board and the four speakers are mounted in the sound box enclosure; the sound box enclosure is composed of a box body and a bottom board fixed on the bottom of the box body; the box body is provided with LED lamps; speaker grills corresponding to two speakers are arranged on the box body; the circuit board is provided with a bluetooth module and a power amplifier; the bluetooth module receives the signal inputted by an external bluetooth device, and after the signal is processed, an audio signal is inputted into the power amplifier and then drives the speakers to utter sound. Since the sound box can be wirelessly connected with a device with the bluetooth function, such as a computer, a mobile phone, a MP3 or a wireless microphone, devices such as an audio cable, an external power amplifier and a CD driver are no longer needed, thereby, the cost is reduced, and mobility and fidelity are improved. Since the sound box adopts the enclosure with a certain shape and the LED lamps are assembled on the box body, the artistic effect of the sound box is enhanced, and with both light and sound, the sound box is more decorative.
