摘要： The present disclosure discloses an acoustic output apparatus. The acoustic output apparatus may include at least one acoustic driver, a housing structure, and at least two sound guide holes. The at least one acoustic driver may output sounds having opposite phases from the at least two sound guide holes. The housing structure may be configured to carry the at least one acoustic driver. The housing structure may include a user contact surface to be in contact with a user. When the user wears the acoustic output apparatus, the user contact surface may be in contact with a body of the user. An included angle between a connection line between the at least two sound guide holes and the user contact surface may be in a range of 75°-105°.

摘要： The invention relates to various rotational action audio transducer embodiments having a diaphragm structure including a single or multiple diaphragms. A diaphragm suspension rotatably mounts the diaphragm structure to a base structure. In some embodiments, the diaphragm suspension may be made from soft and/or damped materials. In some embodiments, the location of an axis of rotation of the diaphragm is determined based on a node axis of the diaphragm. A transducing mechanism of the audio transducer cooperates with the moving diaphragm to transduce sound. The mechanism may comprise a moving magnet design in some embodiments, or a moving coil design in others.

摘要： An acoustic wave device includes a substrate, functional elements on a first main surface of the substrate, an outer support portion on the substrate around a region where the functional elements are disposed, a cover portion opposed to the first main surface of the substrate with the outer support portion interposed therebetween, a support portion in a hollow space defined by the substrate, the outer support portion, and the cover portion, a wiring pattern electrically connected to the functional elements, and a through electrode extending through the substrate and electrically connected to the wiring pattern. A gap is provided between the support portion and the cover portion. A distance from the first main surface of the substrate to an upper surface of the support portion is greater than a distance from the first main surface of the substrate to an upper surface of the functional elements.

摘要： An acoustic transducer that includes a housing, a diaphragm, a spider, a motor, and a drop ring. The motor includes a backplate, a frontplate, a magnet, and a voice coil. The drop ring connects the diaphragm to the spider at a circumference of the spider. The drop ring extends parallel with respect to a central axis of the housing. The circumference of the spider is spaced away from the motor and connects to the diaphragm at a resonant node of the diaphragm.
