Abstract
A portable electronic device comprising: an enclosure having an enclosure wall that forms an interior chamber and a sound output port to an ambient environment; a transducer positioned within the interior chamber and dividing the interior chamber into a front volume chamber coupling a first side of the transducer to the sound output port and a back volume chamber coupled to a second side of the transducer; and an electromechanical valve comprising a number of flaps operable to open and close a vent to the interior chamber, the front volume chamber or the back volume chamber.
Claims20
A portable electronic device comprising:
- an enclosure having an enclosure wall that forms an interior chamber and a sound output port to an ambient environment;
- a transducer positioned within the interior chamber and dividing the interior chamber into a front volume chamber coupling a first side of the transducer to the sound output port and a back volume chamber coupled to a second side of the transducer;
- and
- an electromechanical valve comprising a number of flaps operable to open and close a vent to the interior chamber, the front volume chamber or the back volume chamber, and at least one flap of the number of flaps comprises a first material layer, a second material layer and a third material layer.
A valve assembly for a portable electronic device, the valve assembly comprising:
- a support member coupled to an enclosure opening, the support member having an insulating layer;
- and
- an electromechanical flap movably coupled to the support member, the electromechanical flap comprising a first material layer, a second material layer, a third material layer, and a fourth material layer, and wherein upon application of a voltage, the electromechanical flap is operable to transition between a closed configuration in which the electromechanical flap covers the enclosure opening and an open configuration in which the electromechanical flap uncovers the enclosure opening.
