摘要： A metamaterial loudspeaker diaphragm is disclosed. The diaphragm includes a cone structure having a periodic arrangement of two dissimilar materials, e.g., soft and hard, in an alternating periodic pattern to achieve an anisotropic structure, which results in passive amplification of the sound. The anisotropic cone structure includes a baseline cone material and a different, compatible second material. The cone includes a body having a conical cross-section, an interior side, an exterior side, and concentric circles of material alternating between a soft material and a rigid material. Circumferential grooves disposed within the concentric circles include rigid material. Concentric circles including rigid material line the interior side of the body. Substantially all the soft material of the concentric circles is disposed on the exterior side of the cone. Spokes disposed on the exterior side of the cone extend from a base toward a vertex of the cone.

摘要： There is provided a sound device used while being worn on the listener's ears.
The sound device includes a main body installed on a medial surface of an auricle, a holding portion having an annular hollow structure arranged to be coupled to an intertragic notch of an ear near an entrance of an ear canal, a sound guide portion formed as a pipe structure having one end communicating with the main body and another end communicating with the holding portion, an open/close operation unit configured to open or close an earhole, and a control unit configured to control driving of the open/close operation unit. The earhole open/close state is set for each user. The earhole open/close state can be switched depending on the type of application or content to be played, ambient noise level, user behavior, position information, or the like.-

摘要： An acoustic liquid transfer system that includes a processor; a source holding component configured to hold a source microplate; a destination holding component configured to hold a destination microplate; an acoustic transducer configured to cause liquid to transfer between the source and destination microplates; and a controller configured to direct movements, according to an ordered picklist, of one or more of the: source holding component, destination holding component, and acoustic transducer. The processor is configured to access an initial picklist of a plurality of source/destination pairs; obtain a current source/destination pair on the ordered picklist being created; calculate a plurality of movement metrics between the current source/destination pair and at least some of the plurality of source/destination pairs on the initial picklist but not yet on the ordered picklist; select a next source/destination pair with reference to the movement metrics; and add the next source/destination pair to the ordered picklist.

摘要： The present disclosure provides a reliable structure which can prevent disconnection of a voice coil lead wire, while employing a voice coil embodied as an aluminum coil to improve the mid-frequency band SPL of a slim high-pressure water resistant microspeaker. According to the present disclosure, there is provided a high-pressure water resistant microspeaker with an improved coil structure, including an FPCB attached to the outer surface of a frame, a pad of the FPCB extending inside the frame and another part of the FPCB extending outside the frame. The upper end of the voice coil is attached to an overlapping position of a side diaphragm and a center diaphragm, and the lower end of the voice coil is supported by the part of the FPCB extending inside the frame.
