Abstract: A piezoelectric generation system and piezoelectric generating method for use in a nebulizer are disclosed. The system and method comprises using a processing unit to control the frequency generation unit to continuously generate the first electrical signals with a serial predetermined frequency band range (or third electrical signals after converting the first electrical signals) to be transmitted to a piezoelectric generating element. The piezoelectric generating element then generates a series of corresponding second electrical signals (or the fourth electrical signals after converting the second electrical signals) to be transmitted to the processing unit based on the first electrical signals or the third electrical signals.

Abstract: A droplet generation apparatus is applied to a nebulizer. The droplet generation apparatus comprises a vibratable member, a nozzle disc, a housing and a connection member or a fastening plate or both the connection member and the fastening plate. The vibratable member has a first through hole. The nozzle disc has a plurality of apertures facing the first through hole, and is combined with the vibratable member. The connection member is disposed between the vibratable member and the nozzle disc, and has a second through hole corresponding to the first through hole. Alternatively, the fastening plate is combined with the nozzle disc. The housing covers up the combination of the vibratable member, the nozzle disc and the connection member or the fastening plate. Vibration efficiency generated by the vibratable member is improved through the connection member. An accommodation space is formed by the fastening plate and the nozzle disc.

Abstract: A luminous key mechanism. A keycap moves with respect to a base plate and includes a transparent window. A light-emitting element is disposed under the keycap. A condenser is connected to the transparent window and opposes the light-emitting element. Light output from the light-emitting element is condensed by the condenser and output via the transparent window.

Abstract: A luminous keyboard includes a circuit board, an elastic layer and a light module. The elastic layer on the circuit board includes a plurality of elastic portions. The light module includes a light guiding element and a light source. The light source is installed on the circuit board. The light guiding element covers the light source and includes an anti-dazzle portion and a light penetrating portion. The anti-dazzle portion blocks some light from the light source. The other light passes through the light penetrating portion illuminating the key.
