Abstract
An external sound box includes a connecting member and a sound box. The connecting member includes a sound passage and is selectively attachable to a surface of an electronic device to cover a sounding hole of the electronic device. The sound box is mounted to the connecting member. The sound box defines a resonant chamber communicating with the sound passage and a sounding output hole. Sound generated by the electronic device moves from the sounding hole into the sound passage and the sound box. The sounding passage and the sound box are configured so that the sound from the sounding hole resonates before exiting the sound output hole with increased volume.

An external sound box for an electronic device comprising:
- a connecting member with a sound passage, the connecting member selectively attachable to a surface of the electronic device to cover a sounding hole of the electronic device;
- and
- a sound box mounted on the connecting member, the sound box defining a resonant chamber communicating with the sound passage and comprising a sound output hole;
- wherein, sound generated by the electronic device moves from the sounding hole into the sound passage and the sound box;
- and
- wherein, the sounding passage and the sound box are configured so that the sound from the sounding hole resonates before exiting the sound output hole with increased volume.
A loudspeaker module comprising:
- a loudspeaker having at least one sound outlet;
- a connecting member with a sound passage, the connecting member selectively attachable to a surface of the electronic device to cover the at least one sound outlet;
- and
- a sound box defining a resonant chamber and a sounding output hole, and the sound box mounted to the connecting member in a manner that sound generated by loudspeaker passes through the at least one sound outlet and the sound passage, resonates in the sound passage and the resonant chamber, and leaks from the sounding output hole with increased volume.
An electronic device comprising:
- a housing defining a sounding hole;
- and
- a loudspeaker module, the loudspeaker comprising:
- a loudspeaker mounted to an interior of the housing;
- a connecting member with a sound passage, the connecting member selectively attachable to an exterior of the housing to cover the sounding hole;
- and
- a sound box defining a resonant chamber and a sounding output hole, and the sound box mounted to the connecting member in a manner that sound generated by loudspeaker passes through from the sound passage, resonates in the sound passage and the resonant chamber, and leaks from the sounding output hole with increased volume.
