摘要： A glass plate construct provided with a first glass plate, a second plate disposed facing the first glass plate, and a liquid layer formed by sealing a liquid between the first glass plate and the second plate, the glass plate construct having a plurality of vibration areas that are independent from each other in a plan view. The glass plate construct is a diaphragm including at least one vibrator installed on one side or both sides of the glass plate construct. Independent vibration in each of the vibration areas is made possible, thus enabling stereophonic or multidimensional reproduction, as well as enabling local reproduction matched to a video. Furthermore, because the present invention is a diaphragm that includes a vibrator, sound reproduction is exceptional.

摘要： A vibration component for loudspeakers includes a base layer, an intermediate layer, and a coating layer. The base layer has a front face and a rear face, has a first density, and is formed of a paper body containing a plurality of fibers. The intermediate layer has a first face joined to the front face of the base layer, and a second face on a reverse side of the intermediate layer from the first face, has a second density higher than the first density, and includes a plurality of cellulose fibers as a main component. The coating layer is provided on the second face of the intermediate layer, and includes an inorganic powder formed of a plurality of inorganic fine particles.

摘要： A loudspeaker diaphragm includes a continuous coating on at least one surface of the diaphragm. The continuous coating may be non-uniform and may taper from a maximum in value in a conical region of the diaphragm to a minimum value in a cylindrical region of the diaphragm. The coating is formed in a single coating step without the need for use of a contact mask or interruption of the process to change process parameters. The tapered coating is formed by controlling the current density distribution within an electrochemical cell such that the rate of formation of the coating tapers from a first value in the conical region of the diaphragm to a second value is the cylindrical region of the diaphragm.

摘要： A speaker device having an improved sound quality is provided. The speaker device according to one embodiment of the present invention includes a vibration generator (1), a rod-like member (2), and a sound generator (3). The vibration generator (1) vibrates when receiving an electrical signal. The rod-like member (2) has a first longitudinal end fixed to the vibration generator (1). The sound generator (3) is attached to a part of the rod-like member (2). The sound generator (3) integrally includes a vibration transmitter (30) which has a fibrous structure and a diaphragm (31) which is a sheet and has a fibrous structure. When a fiber direction is defined as a direction in which fibers of a fibrous structure are oriented, a fiber direction of the vibration transmitter (30) and a fiber direction of the diaphragm (31) intersect with each other.
