Abstract

A motor apparatus includes a motor body, a circuit board, a driver, and a voice detector. The circuit board, which is connected to the motor body, supplies driving electric power to the motor body. The driver, which is mounted on the circuit board, converts power source electric power to the driving electric power. The voice detector, which is mounted on the circuit board, detects a voice.

First claim

What is claimed is:

1. A motor apparatus comprising:
a motor body;
a circuit board connected to the motor body to supply driving electric power to the motor body;
a driver mounted on the circuit board to convert power source electric power to the driving electric power;
a voice detector mounted on the circuit board to detect a voice;
an integrated controller mounted on the circuit board to control the motor body; and
a communication circuit mounted on the circuit board to transmit to an external apparatus voice data based on a voice detected by the voice detector; wherein
the external apparatus is an additional motor apparatus other than the motor apparatus.

2. The motor apparatus according to claim 1 , wherein
the driver includes an inverter circuit to convert the power source electric power to the driving electric power according to open/close operations of a plurality of switches; and
the motor body includes a brushless DC motor that operates according to the driving electric power.

3. The motor apparatus according to claim 1 , wherein the integrated controller performs signal processing on voice data based on the voice detected by the voice detector.

4. The motor apparatus according to claim 1 , wherein the integrated controller controls an operation of the motor body according to the voice detected by the voice detector.

5. The motor apparatus according to claim 1 , wherein the integrated controller performs processing to recognize a voice detected by the voice detector and controls an operation of the motor body according to a voice recognition result.

6. The motor apparatus according to claim 1 , wherein
the additional motor apparatus includes an additional motor body and an additional communication circuit.

7. The motor apparatus according to claim 1 , wherein
the voice detector includes a MEMS microphone.

8. The motor apparatus according to claim 2 , wherein
the circuit board further includes a power supply circuit connected to the inverter circuit.

9. A motor system in which a plurality of motor apparatuses mutually communicate according to a predetermined protocol, each of the plurality of motor apparatuses comprising:
a motor body;
a circuit board connected to the motor body to supply driving electric power that drives the motor body;
a driver mounted on the circuit board to convert power source electric power to the driving electric power;
a voice detector mounted on the circuit board to detect a voice;
an integrated controller to control an operation of the motor body; and
a communication circuit mounted on the circuit board to transmit voice data based on a voice detected by the voice detector to a motor apparatus other than the motor apparatus from which the voice data has been transmitted.

10. The motor system according to claim 9 , wherein each integrated controller in the plurality of motor apparatuses controls an operation of the motor body according to voice data received from the communication circuit.

11. The motor system according to claim 9 , wherein
the motor apparatus other than the motor apparatus from which the voice data has been transmitted includes an additional motor body and an additional communication circuit.

12. The motor system according to claim 9 , wherein
the circuit board further includes a power supply circuit connected to an inverter circuit.

13. The motor system according to claim 9 , wherein
the voice detector includes a MEMS microphone.
