Abstract
An electronic device includes an internal speaker module and an external sound box detachably applied to the internal speaker module. The valve is resisted to the opening to cover the opening of the internal speaker module. When external sound box is applied to the internal speaker module, the connector is magnetically attracted with the magnetic attracter, while the valve is magnetically repelled from the connector and moves away from the opening to open the opening, thereby the external sound chamber is communicating with the internal sound chamber.
Claims20
A speaker module for an electronic device, comprising:
- an internal speaker module, comprising:
- a speaker;
- and
- an internal sound chamber, the internal sound chamber receiving the speaker therein and providing a resonating space for sound generated by the speaker, the internal sound chamber including:
- an opening defined on one end portion of the internal sound chamber, and communicating with the resonating space;
- a magnetic attracter mounted to the end portion;
- a valve mounted in the internal sound chamber and made of magnetic material;
- and
- an external sound box detachably applied to the internal speaker module, comprising:
- an additional resonating space therein;
- a window defined on a sidewall of the external sound box, and communicating with the additional resonating space;
- and
- a connector mounted to the sidewall and made of magnetic material;
- wherein when the external sound box is separated from the internal speaker module, the valve is magnetically attracted with the magnetic attracter and covers the opening to form a closed resonating space for the internal sound chamber;
- and when the external sound box is coupled to the internal speaker module, the connector is magnetically attracted with the magnetic attractor to connect the external sound box to the internal speaker module, and the valve is magnetically repelled with the magnetic attracter and moves away from the opening to allow communication between the additional resonating space and the resonating space via the window and the opening.
