  • Patent number: 11682375
    Abstract: A speaker system includes a wearable speaker capable of outputting a first sound which is a voice of a communication partner of a talker and a second sound, a microphone, and a sound processing device which processes a sound output from the wearable speaker and a sound picked up by the microphone. The sound processing device generates a reference signal by synthesizing a first signal indicating the first sound and a second signal indicating the second sound, outputs the first signal and the second signal to the wearable speaker, obtains a sound pickup signal including the voice of the talker from the microphone, performs, on the sound pickup signal, a process of cancelling the sound component output from the wearable speaker by using the reference signal, and outputs the sound pickup signal on which the cancellation process has been performed.

  • Patent number: 11251499
    Abstract: A battery cover includes: a case for housing a battery; and a rib formed on an inner peripheral face of the case to form a first space between the inner peripheral face of the case and an outer peripheral face of the battery. The case has an air hole that communicates the inside and outside of the case, a first housing part for housing a positive electrode of the battery, and a second housing part for housing a negative electrode of the battery. The air hole is disposed in a position in the case closer to the second housing part than to the first housing part.

  • Patent number: 10856061
    Abstract: A speaker device includes a housing that has a sound guide space having a vertically flattened shape, a first speaker disposed in the housing to be oriented toward a front of the housing, and a second speaker that is disposed in the housing and is oriented upward or downward to output sound into the sound guide space positioned at an internal upper part or an internal lower part of the housing. The sound guide space opens at an opening that is formed in vertically flattened form in the housing, and the opening has a vertical height that is smaller than an aperture of the first speaker.

  • Patent number: 10674275
    Abstract: An electroacoustic transducer includes: a diaphragm; a frame that is disposed around the diaphragm so as to surround the diaphragm; an edge that closes a space between the diaphragm and the frame in a manner of forming a membrane so as to connect the diaphragm and the frame; a base body that supports the frame and has a through sound output hole in front of the diaphragm; a magnet that is attached to the frame; and a voice coil body that is attached to the diaphragm. The frame has an annular first fitting portion that is disposed around the diaphragm so as to surround the diaphragm. The base body has a second fitting portion that fits with the first fitting portion. The electroacoustic transducer further includes a sealing member that is made of a thermoplastic substance and seals a space between the first fitting portion and the second fitting portion fitted with each other.
