Abstract
An acoustic system includes: a charging apparatus, and speakers that are chargeable with the charging apparatus. The speakers include: a speaker unit that generates a sound based on the first electrical signal, and a power reception coil that is configured to be disposed to have at least a part of it overlaps with the extension line of the central axis of a power transmission coil of the charging apparatus and generates electric power to be supplied to the speaker unit with a magnetic flux generated by a power transmission coil.
Claims20
An electro-acoustic transducer system, comprising:
- a first electro-acoustic transducer;
- a second electro-acoustic transducer;
- and
- a charging apparatus that charges the first electro-acoustic transducer and the second electro-acoustic transducer, wherein
- the charging apparatus includes:
- an electric power acquisition part that acquires electric power from an exterior power supply;
- and
- a power transmission coil that generates a magnetic flux based on electric power acquired by the electric power acquisition part, and
- the first electro-acoustic transducer includes:
- a first electro-acoustic transducer part that generates a sound based on a first electrical signal;
- and
- a first power reception coil that generates electric power to be supplied to the first electro-acoustic transducer part with the magnetic flux generated by the power transmission coil, the first power reception coil being configured to be disposed at a position where at least a part of the first power reception coil overlaps with an extension line of a central axis of the power transmission coil, and
- the second electro-acoustic transducer includes:
- a second electro-acoustic transducer part that generates a sound based on a second electrical signal;
- and
- a second power reception coil that generates electric power to be supplied to the second electro-acoustic transducer part with the magnetic flux generated by the power transmission coil, the second power reception coil being configured to be disposed at a position where at least a part of the second power reception coil overlaps with the extension line of the central axis of the power transmission coil.
