Abstract: Embodiments of the present disclosure provide an inverter vent and a loudspeaker having the same. Preferably, air flows within the inverted vent in a 360 degrees full-circumferential direction. This design can improve the efficiency of the loudspeaker, reduce the wind noise, and increase the bass ductility.

Abstract: A protection device includes a cladding cover and a folding cover. A portable electronic device is detachably disposed on the cladding cover. The cladding cover includes a first connector and a first combining portion. The first connector includes a first joint and a second joint. The first joint contacts a first terminal set of the portable electronic device since the portable electronic device is disposed on the cladding cover. The folding cover includes a second terminal set and a second combining portion. The second terminal set contacts the second joint since the cladding cover is assembled with the folding cover. The first/second combining portions are respectively disposed around the first/second terminal sets. The second combining portion is rotatably combined with the first combining portion so that the cladding cover is switched relative to the folding cover between a first position and a second position.

Abstract: A low noise clock oscillator in standard surface mount plastic or ceramic form. With the same soldering pads design such devices can be replace with a convention standard surface mount clock oscillator to reduce Electro-magnetic Interference or RFI (Radio Frequency Interference) without redesign of the main board. The oscillator is characterized by using a spectrum spread clock generator and a spread controller on an elevated platform to reduce common mode emission currents.
