Embodiment Construction
[0018] A preferred embodiment of the present invention discloses an electronic device 500 that can be connected to an external speaker. The electronic device 500 can be a portable electronic device such as a mobile phone, a personal digital assistant (PDA), a tablet computer, MP3 and MP4, and the like. The electronic device 500 can improve the sound quality by connecting an external speaker 200 .
[0019] see figure 1 and figure 2 , the electronic device 500 includes a speaker assembly 510 . The speaker assembly 510 includes a built-in speaker set 100 and the external sound box 200 , and the external sound box 200 is detachably connected to the built-in speaker set 100 . The built-in speaker set 100 includes a speaker 20 and an internal sound cavity 30 . The inner sound cavity 30 can be formed in the electronic device 500 , or can be manufactured separately and installed on the electronic device 500 .
[0020] The inner sound cavity 30 includes an opening 32 , a magnetic ...

An electronic device comprises an internally-arranged loudspeaker set with an inner sound cavity and an externally-connected loudspeaker box with an outer sound cavity. The inner sound cavity comprises an opening, a magnet attraction piece, a valve and a guide portion, the opening is formed in one end of the inner sound cavity, and a flange is arranged on the portion, around the inner wall of the opening, of the inner sound cavity in a protruding mode. The magnet attraction piece is arranged on the side, facing outwards, of the flange. The valve is made of a magnetic material, one magnetic pole face faces the magnet attraction piece and the valve is attracted by magnetism of the magnet attraction piece so as to be attached to the inner wall of the flange, so that the opening is closed. The guide portion is opposite to the opening and is arranged in the inner sound cavity. The externally-connected loudspeaker box comprises a magnetic connecting piece arranged at one end of the loudspeaker box, the magnetic pole face of the connecting piece faces the magnet attraction piece, and a connecting hole is formed in the middle of the connecting piece. When the connecting piece is magnetically attracted to the magnet attraction piece, the magnetism of the connecting piece repels the magnetism of the valve, so that the valve moves in the guide portion with the back facing to the opening and positioned in the guide portion. The connecting hole is correspondingly communicated with the opening, so that the outer sound cavity is communicated with the inner sound cavity. The invention further provides the loudspeaker set and the externally-connected loudspeaker box.
Description
technical field [0001] The present invention relates to an electronic device and an external sound box, in particular to a convenient electronic device that can be connected to an external sound box and the corresponding external sound box. Background technique [0002] Common portable electronic devices are equipped with speaker components for playing audio files and the like. A certain space is usually reserved in the speaker assembly as the sound cavity of the speaker, so that the sound emitted by the speaker can resonate. However, due to the limitation of the external size of the portable electronic device, the design space of the sound cavity is small, so that the space for the sound from the speaker to resonate is insufficient, resulting in sharp sound, poor low-frequency sound, and poor sound quality. It has become an important issue to improve the sound quality of the sound produced by the portable electronic device without affecting the volume of the portable elect...
