Abstract:
1. An electronic device with speakers, comprising: a first housing, the first housing comprising a bottom wall and a peripheral wall surrounding and extending downwardly from the bottom wall; the first housing defining two opposite vents in the peripheral wall; a second housing assembled to the first housing; a circuit board positioned between the first and second housings, the circuit board comprising a first surface facing the first housing and a second surface facing the second housing; two speakers attached to the first surface of the circuit board; and an antenna attached to the second surface of the circuit board, the antenna comprising two recessed sections; wherein the first housing defines two receiving recesses in a surface facing the circuit board and two first through holes each adjacent to one corresponding receiving recess; each receiving recess defines a second through hole in a bottom thereof; the two speakers are received in corresponding receiving recesses; each receiving recess communicates with one corresponding vent to form a front resonating chamber for the corresponding speaker; the circuit board defines two third through holes aligned with the two first through holes and communicating with the two recessed sections; the bottom wall defines two first channels transversely extending therein; each of the first channels communicates with one corresponding first through hole and one corresponding second through hole; the first through holes, the second through holes, the third through holes, the recessed sections, and the vents communicate with each other and cooperatively form two back resonating chambers for the two speakers, respectively.
