Methods for providing a customized audio experience to a user of an audio output device are provided. A user interface is provided on a user device communicatively coupled to the audio output device, the user interface capable of accepting user input for managing the audio experience for the user. A set of activities is provided via the user interface, wherein each activity in the set invokes a set of behaviors configured for the activity for providing the customized audio experience to the user, wherein each behavior in the set customizes the audio experience for the user. A capability is provided via the user interface for the user to launch an activity from the set for invoking the set of behaviors configured for the activity to receive the customized audio experience.

A sound reduction device for use in a mechanical machining method or a joining method, in particular a pulse-type joining method. The sound reduction device comprises a clamping device by means of which at least one part to be machined can be clamped at a plurality of clamping locations, as well as a plurality of engagement components which engage the part surface at a number of engagement points, in order to damp vibrations of the part. The present disclosure also describes a joining method and a machining method in combination with the sound reduction device.

An automatic robot control system and methods relating thereto are described. These systems include components such as a touch screen panel (“TSP”) robot controller for controlling a TSP robot, a camera robot controller for controlling a camera robot and an audio robot controller for controlling an audio robot. The TSP robot operates inside a TSP testing subsystem, the camera robot operates inside a camera testing subsystem, and the audio robot operates inside an audio testing subsystem. Inside the audio testing subsystem, an audio signals measurement system, using a bi-directional coupling, controls the operation of the audio robot controller. In this control scheme, a test application controller is designed to control the different types of subsystem robots. Methods relating to TSP, camera, and audio robots, and their controllers, taken individually or in combination, for automatic testing of device functionalities are also described.

A variable acoustic assembly comprising a housing and a one or more absorbing pads. The housing contains the one or more absorbing pads, a one or more doors, a one or more rear brackets, and a one or more hinges. The one or more doors attach to the one or more rear brackets with the one or more hinges. The one or more doors are configured to selectively open and selectively close between an open configuration and a closed configuration by rotating on the one or more hinges. The variable acoustic assembly having a closed width in the closed configuration and an open width in the open configuration. With the one or more doors in the open configuration, a portion of the one or more absorbing pads are exposed outside of the housing.

A method for audio signal noise cancellation is provided. In response to current noise cancellation coefficients being required to be updated to new noise cancellation coefficients, the digital signal processor calculates the new noise cancellation coefficients and writes the new noise cancellation coefficients into an idle storage module in the at least two storage modules, and the digital signal processor sends an update request for updating the noise cancellation coefficients to the active noise cancellation module. The update request carries position information configured to indicate a position of the storage module to which the new noise cancellation coefficients is written. The active noise cancellation module reads the new noise cancellation coefficients in the storage module indicated by the position information based on the position information carried in the update request, and performs noise cancellation processing according to the new noise cancellation coefficients after a current noise cancellation processing cycle ends.

A laminated structure for use in retrofit building construction (partition, wall, ceiling, floor or door) that exhibits improved acoustical sound proofing characteristics while being optimized for efficient installation. The laminated structure includes a panel with at least one layer of viscoelastic glue, or fire-10 resistant, viscoelastic glue, which functions both as a glue and an energy dissipating layer. In one embodiment, the laminated structure to be attached to an existing wall in some embodiments includes standard paper-faced gypsum board. In another embodiment the to-be-applied laminated structure includes a cement-based board, and in yet another embodiment the to-be-applied laminated 15 structure includes a cellulose-based board. Once the laminated structure is installed on an existing wall or other partition, the resulting structure greatly attenuates transmitted noise and minimizes the labor required for installation and finishing.

The present invention provides a speaker, including: a housing body having an accommodation cavity with a first chamber and a second chamber; a first side wall and a second side wall enclosing the first chamber; a third side wall and a fourth side wall enclosing the second chamber; and a speaker unit including a connection part located in the first chamber and a sounding component connecting to the connection part. A distance between the first side wall and the second side wall is smaller than a distance between the third side wall and the fourth side wall. The speaker enables the connection part to be connected to the side wall of the housing body without the end of the connection part needing to exceed the end of the sounding component, which reduces the volume of the housing body and facilitates the miniaturized design of the speaker.
