Abstract: An electronic device includes a first housing, a second housing engaged with the first housing, a circuit board enclosed between the first and second housings, two speakers, and an antenna. The speakers and the antenna are attached to two sides of the circuit board. 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. The speakers are received in the receiving recesses. The receiving recesses communicate with the vents to form front resonating chambers for the speakers. The circuit board defines two third through holes aligned with the first through holes and communicating with the recessed sections. The first, second, and third through holes, the recessed sections, and the vents communicate with each other to form back resonating chambers for the speakers.

Abstract: A housing assembly includes a housing and a speaker module. The housing defines a slot. The speaker module is assembled to the housing. The speaker module includes a speaker and a base. The speaker is received in the base. The base includes a protrusion protruding from a side surface of the base and surrounding the base. The base is received in the slot. The protrusion is fixed to an inner surface of the housing around the slot.

Abstract: A sound amplifying device includes a base part and an amplifying part. The amplifying part is mounted on the base part. The amplifying part includes a reflecting wall and a bracket. The reflecting wall has a hollow semi-ellipse shape with a semi major axis and a minor axis. The bracket is mounted on the reflecting wall and has one end positioned on the semi major axis. An electronic product using the sound amplifying device includes the sound amplifying device and an electronic device removably mounted on the sound amplifying device. The sound amplifying device generates a maximum loudness effect.

Abstract: A speaker assembly is configured for assembly to a housing. The housing defines a through hole and a receiving groove communicating with each other. The speaker assembly includes a speaker and a speaker cover. The speaker is received in the through hole. The speaker cover has an extending edge beyond a peripheral wall of the speaker and is received in the receiving groove.

Abstract: A portable electronic device (40) includes a main body (10), a speaker (20), and a latching mechanism (30). The speaker is movable relative to the main body and has a positioning stop member (262) associated therewith. The latching mechanism is mounted in a longitudinal side of the main body and has a latching body (31). The latching body is configured for selectable biased engagement with the positioning stop member to enable the speaker to be selectably retained within the main body. The speaker further includes a speaker-driving elastic member (28), and the main body further includes a partition wall (132) and has a cavity (131) defined therein. The partition wall is in communication with the cavity. A first end of the speaker-driving elastic member resists the partition wall, and a second opposite end of the speaker-driving elastic member resists the speaker.
