Goodly, trepanning 36 is exposed by another appearance of electronic device 500.
The loud speaker 20 is contained in the trepanning 36 of interior sound chamber 30.The sound that loud speaker 20 is sent out hair in interior sound chamber 30
It is spread out of again via other sound outlet holes of trepanning 36 or electronic device 500 being connected to interior sound chamber 30 after raw resonance.The loud speaker 20
It is electrically connected to the mainboard of electronic device 500, can be used for playing the audio file of the electronic device 500 or sends out system sounds
Deng.
The valve 38 is installed in inside the interior sound chamber 30, can be attached to the inner wall of 32 peripheries of opening to close opening
32, or moved backwards to the opening 32.38 rectangular-blocklike of valve, area of the area than the opening 32 of the interior sound chamber 30
Greatly.The valve 38 is made of magnetic material, and with a magnetic pole, such as South Pole, towards the opening 32；Then another magnetic pole of valve 38,
Such as the arctic, backwards to the opening 32.When electronic device 500 is not connected with circumscribed speaker 200, the magnetic valve 38 and magnetically attractive part 34
Magnetic attraction, valve 38 are close to support by absorption to the inner wall of the flange 322, independent to be formed to close the opening 32
Closed interior sound chamber 30.
The guide portion 39, which includes at least the setting of opposed open 32, extends projection by the inner wall of interior sound chamber 30 supports wall
392, to guide valve 38 to move and position between opening 32 and guide portion 39.It is appreciated that prevent valve 38 in movement
Middle that unnecessary lateral displacement occurs and causes it that cannot close opening 32, which can further include to surround and open
32 peripheries of mouth are arranged in opening 32 and support the guiding wall 394 between wall 392.The space that guide portion 39 is surrounded and interior sound chamber 30
Its interior complementary space is connected, that is, guide portion 39 is not by the closed separation of other parts of opening 32 and interior sound chamber 30.
Also referring to Fig. 3 and Fig. 4, which can connect a circumscribed speaker 200 to the boombox group
100.The 200 rectangular box body shape of circumscribed speaker, inner hollow form outer sound chamber 210.The outer sound of the circumscribed speaker 200
The volume of the interior sound chamber 30 of the volumetric ratio of chamber 210 loudspeaker assembly 510 is big.The inner wall of the outer sound chamber 210 is by airtight material system
At for preventing the sound in outer sound chamber 210 from revealing.
The circumscribed speaker 200 includes opening portion 220, connector 230 and sealing element 240.The opening portion 220 is opened in
One end of outer sound chamber 210.Preferably, opening portion 220 is exposed by an appearance of circumscribed speaker 200.
The connector 230 is installed in the opening portion 220.The rectangular cyclic annular block of the connector 230, middle part opens up
There are a rectangle connecting hole 232, connecting hole 232 to be connected to outside 210 inside of outer sound chamber and circumscribed speaker 200.The connecting hole 232 with
The appearance and size of the through-hole of the opening 32 and magnetically attractive part 34 is suitable.The connector 230 is made of magnetic material, lateral surface one
Magnetic pole, such as South Pole；Its medial surface is another magnetic pole, such as arctic.Connector 230 is fixed to the magnetically attractive part 34 for magnetic, with
Circumscribed speaker 200 is connected to boombox group 100.
The sealing element 240 is installed in the lateral surface of connector 230, the 240 rectangular ring-type of sealing element, and hollow is logical
Hole is directed at the connecting hole 232.The sealing element 240 is made of airtight material.
Also referring to Fig. 5 and Fig. 6, when the circumscribed speaker 200 is connected to the electronic device 500, the connector 230
With the magnetic attraction of the magnetically attractive part 34 so that the opposite boombox group 100 of the circumscribed speaker 200 is close.At the same time,
Due to the connector 230 towards the magnetically attractive part 34 when the while magnetic having the same with the valve 38 towards the magnetically attractive part 34
Pole, such as South Pole, i.e. connector 230 are repelled each other with 38 magnetism of valve so that the valve 38 is acted in the magnetic repulsion force of the connector 230
Under leave flange 322 and backwards to the opening 32 move.Until the connector 230 is adsorbed on the magnetically attractive part 34, which exists
With being moved to support under the magnetic repulsion force effect of connector 230 wall 392 is supported at this.The circumscribed speaker 200, which is fixed, as a result, connects
It is connected on the outside of the boombox group 100.At this point, the connector 230 connecting hole 232 be aligned the magnetically attractive part 34 through-hole and
The opening 32 of interior sound chamber 30, to so that the outer sound chamber 210 of the circumscribed speaker 200 is connected to interior sound chamber 30 and formed one it is larger
Sound chamber, the sound that loud speaker 20 is sent out occurs resonance in the interior sound chamber 30 and outer sound chamber 210 of the connection, can enhance all-bottom sound
The quality of sound.The sealing element 240 is held between the connector 230 and magnetically attractive part 34, can be the interior sound chamber 30 and outer sound chamber 210
Between airtight combination condition is provided.
The boombox group 100 of the electronic device 500 of the present invention is external to be connected to by connecting circumscribed speaker 200
The outer sound chamber 210 of formula speaker 200 and the interior sound chamber 30 of boombox group 100 make the sound that loud speaker 20 is sent out have larger
Resonance space, can effectively enhance the quality of low-frequency sound.In addition, by having magnetic company in the setting of circumscribed speaker 200
Fitting 230 makes circumscribed speaker 200 be automatically connected to the magnetically attractive part 34 of electronic device 500, and is denounceed by the magnetism of same pole
Power makes interior sound chamber 30 be connected to outer sound chamber 210 after so that valve 38 is moved.Therefore, which can facilitate raises built in connection
Sound device group 100 is with circumscribed speaker 200 to promote sound quality.
