Abstract
An ultra-thin speaker includes a metal upper casing, and a metal lower casing corresponding to the metal upper casing and capable of covering a vibrating membrane, a support frame, a magnet and a yoke between two corresponding internal surfaces of the metal upper and lower casings and forming a contact surface with the yoke, such that after the yoke conducts heat of a heat source to the metal lower casing, the heat is conducted to the metal upper casing through a connection and a contact of the metal upper and lower casings to increase a heat dissipating area, so as to overcome the heat dissipation problem and minimize the overall thickness of the speaker.
Claims13
An ultra-thin speaker, comprising:
- a) a metal upper casing, having an external surface, an internal surface, and one or more sound holes formed at the middle of the metal upper casing;
- b) a vibrating membrane, positioned at the internal surface of the metal upper casing;
- c) a voice coil, positioned at the bottom of the vibrating membrane;
- d) a support frame, positioned at the bottom of the metal upper casing and the vibrating membrane, and having a first hollow hole formed at the middle of the support frame;
- e) a magnet, positioned in the first hollow hole;
- f) a yoke, positioned at the bottom of the support frame;
- and
- g) a metal lower casing, positioned corresponding to the metal upper casing, and having an external surface and an internal surface, and provided for covering the aforementioned components between the two corresponding internal surfaces, and forming a contact surface with the yoke;
- such that after the yoke conducts heat of a heat source to the metal lower casing, the heat is conducted to the metal upper casing through a connection and a contact between the upper and lower casings to increase a heat dissipating area.
