Abstract: An electromagnetic relay has a contact device and an electromagnet device. An electromagnetic relay has stators which are a pair of rod-like members, and a mover. The mover may face the side of the stator. A housing supports the stator and accommodates the mover. A yoke is fixed to the housing so as to face the movable facing surface and contains a soft magnetic material.

Abstract: An audio output device includes PWM output devices, a weighting unit, a mixer, and an amplifier. The PWM output devices divide audio data into multiple parts including an upper bit part to a lower bit part, and output the multiple parts of the audio data as PWM outputs. The weighting unit weights the PWM outputs from the PWM output devices. The mixer synthesizes the PWM outputs after being weighted. The amplifier supplies an electric current to a sounding body in accordance with a synthesis result by the mixer to cause the sounding body to emit a sound.

Abstract: An electromagnetic relay includes: an excitation coil; a movable core; a movable contactor that operates by following the movable core; a fixed contactor that is in contact with the movable contactor when the excitation coil is energized; a base that supports the fixed contactor; a fixed yoke fixed to the base; a moving yoke; a first pressing spring that biases the moving yoke toward the movable contactor; and a second pressing spring that biases the movable contactor such that the movable contactor and the fixed contactor are in contact with each other. The moving yoke is disposed to be in contact with a surface of the movable contactor opposite from the fixed contactor and to oppose the fixed yoke through the movable contactor. The moving yoke is provided to be able to contact and separate from the movable contactor.
