Sound-output device

A sound-output device, comprising:

• a signal processing module configured to generate a control signal;
• a housing;
• a magnetic circuit system configured to generate a first magnetic field;
• a vibration plate connected to the housing;
• a coil connected to the vibration plate and electrically connected to the signal processing module to receive the control signal and generate a second magnetic field based on the control signal, the first magnetic field interacting with the second magnetic field to cause the vibration plate to generate a bone-conducted sound wave;
• and
• a membrane connected to the magnetic circuit system and the housing, the first magnetic field interacting with the second magnetic field to cause the membrane to generate an air-conducted sound wave, wherein.
• the signal processing module includes a microphone configured to collect an ambient noise signal, a bone-conducted signal processing circuit configured to generate a bone-conducted control signal and an air-conducted signal processing circuit configured to generate an air-conducted control signal.
