The present invention relates to a washbasin having a sound function, in which a concave space part accommodating water is formed at a center of an upper surface of a washbasin body, a valve is installed at a center of the concave space part, and a faucet is installed on an upper surface of a rear side of the washbasin body.

The disclosed computer-implemented method may include (1) establishing a directional wireless link between a first computing device and a second computing device in a first direction, (2) exchanging, over the directional wireless link in the first direction, first data between the first computing device and the second computing device, (3) determining, via a sensor of the first computing device, a change to a position or an orientation of the first computing device, (4) redirecting, based on the change, the directional wireless link to a second direction, and (5) exchanging, over the directional wireless link in the second direction, second data between the first computing device and the second computing device. Various other methods and systems are also disclosed.

A speaker and an electronic device are provided. The speaker includes a counterweight body, and a lower shell, a middle shell, an electric vibration plate, and a dome where the lower shell, the middle shell, and the electric vibration plate are matched to form an accommodating cavity, and the counterweight body is disposed in the accommodating cavity and is connected to a first surface of the electric vibration plate; the dome is disposed on a second surface of the electric vibration plate away from the counterweight body; and when a voltage is applied to the electric vibration plate, the electric vibration plate drives the dome to move.

An electrodynamic compression driver is defined that contains a compression chamber assembly partially bounded by an annular diaphragm. The compression chamber assembly has an annular axisymmetric geometry with a single exit for acoustic radiation. The chamber geometry is further defined such that only the zero-hertz mode of acoustic coupling is supported, allowing the use of a lumped parameter model for analysis of the acoustic coupling of diaphragm and compression chamber. The lumped parameter model is integrated with eigenmode analysis of diaphragm modes and characterization of the cross-coupling between diaphragm and compression chamber. The result is more rapid computation of how to control mechanical modes in the annular diaphragm so that they benefit the compression driver's acoustic output. Embodiments of compression chamber and diaphragms with geometry that facilitate modal control are provided.

An audio demonstration kit encourages understanding of audio concepts by enabling children to construct and study speaker performance. In a particular embodiment, the audio demonstration kit includes a paper speaker and instructions. The paper speaker includes a backplate, a suspension, and a diaphragm cut from a single sheet of paper. The demonstration kit may feature an amplifier that is configurable to accommodate various hardware additions as a child is ready for more progressively challenging construction. For example, the amplifier of an embodiment allows single and dual mode operation, as well as drives a rotary motor and is coordinated with a strobe light. The amplifier of an embodiment is synchronized with the strobe light and a moveable platform to create the impression of that jiggling figures attached to the table are dancing. Interfaces with smart phone, recording, and other technologies further enhances and encourages the learning experience.

Aspects of the disclosure relate to an audio system architecture designed for sound reinforcement. The audio system may comprise one or more input device(s), one or more output device(s), one or more wireless hubs, and one or more user computing devices. Connections between the input device(s), output device(s), and the one or more wireless hubs may be wireless and automated and/or managed via the one or more user computing devices. The user computing devices or the wireless hub may adjust a configuration of each of the devices in the audio system. One or more of the devices in the audio system may be capable of a network connection which may enable recording, live-streaming to remote audiences, system management and operation, cloud-based storage and/or processing, and more.
