A speaker device having a vibration section and generating an audio sound by vibration of the vibration section is provided with a magnetic circuit section for forming a magnetic field for vibrating the vibration section and also with a weight section fixed to the magnetic circuit section and suppressing vibration of the magnetic circuit section subjected to reaction force caused by vibration of the vibration section. The weight section is fixed to the magnetic circuit section through a joint section for joining the magnetic circuit section and the weight section to each other, and this forms between the magnetic circuit section and the weight section a predetermined space for magnetically separating the magnetic circuit section and the weight section from each other."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Speaker device","description":"A speaker device, wherein vibration of a magnetic circuit section is suppressed with a magnetic influence on the magnetic circuit section suppressed.
