The speaker includes a frame, a vibrating diaphragm held in the frame, and a voice coil located below the vibrating diaphragm and configured to drive the vibrating diaphragm to vibrate to produce a sound. The speaker further includes a heat insulation material layer sandwiched at a junction between the vibrating diaphragm and the voice coil. According to the speaker in the present disclosure, the heat insulation material layer is additionally disposed between the vibrating diaphragm and the voice coil. The heat insulation material layer can prevent or reduce heat transferred by the voice coil to the vibrating diaphragm when the voice coil works, thereby reducing creeping of the vibrating diaphragm caused by heat and reducing a change in F0. This increases a frequency response and improves acoustic performance of the speaker.

Abstract: A shell application feature can include trigger information and logic. During operation, the shell application feature can receive an indicator that a trigger occurred; and, in response to the trigger, initiate its logic. The logic of the shell feature is locally performed to identify whether state, object type, user actions, or a combination thereof, with respect to the application satisfy a success criteria corresponding to behavior that will be a prerequisite for a potential feature that is not yet fully implemented. If the state, object type, user action, or combination thereof satisfies the success criteria, a success notification can be communicated to a feature collection service.
