摘要:
A fluid sprayer includes a rigid fluid conduit extending along a conduit axis between longitudinally opposed open conduit first and second ends. A spray nozzle having a fluid-expulsion bore is connected to the conduit second end such that the is nozzle can pivot about a nozzle-pivot axis that extends orthogonally to the conduit axis and fluid introduced into the conduit first end is expelled through the fluid-expulsion bore. An attachment-mounting arm is connected to the fluid conduit for pivotal movement about an arm-pivot axis having a component of spatial extension orthogonal to the conduit axis and being longitudinally non-displaceable relative to the rigid fluid conduit. Moreover, the attachment-mounting arm is selectively lockable into a plurality of discrete angular positions relative to the conduit and configured to removably retain a surface-engaging attachment designed for engaging a surface to be cleaned.
摘要:
An amplifying cover for an audio device that enhances the audio output of the device, such as voice or music, louder and clearer, without adding to the bulk of the device. The cover redirects the audio output of the device to a different location that enhances the ergonomics of the device. The amplifying cover can redirect the sound (while also amplifying it) to the top of the device, closer to the user's ear, or to the side of the device. The amplifying cover can redirect the sound to a plurality of different directions, making it easier to make conference calls. The cover is a protective case for an electronic device that also amplifies the sound produced by the electronic device. The cover provides a portable and compact acoustic amplifier for an electronic device that can be permanently or semi-permanently attached to the electronic device.
