Embodiment Construction

[0036] 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 .

[0037] 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 .

[0038] The inner sound cavity 30 includes an opening 32 , a magnetic ...

Abstract

An electronic device includes a built-in speaker group including an inner sound chamber and an external sound box including an outer sound chamber. The inner sound chamber includes an opening, a magnetic member, a valve and a guide part. The opening is set at one end of the inner sound chamber, and a flange is protruded from the inner wall of the inner sound chamber surrounding the opening. The magnetic absorbing part is arranged on the side facing outward of the flange. The valve is made of magnetic material, and a magnetic pole faces the magnetic part. The valve and the magnetic part are magnetically attracted so that the valve is attached to the inner wall of the flange, thereby closing the opening. The type sound box includes a magnetic connecting piece installed at one end thereof, the connecting piece has a magnetic pole facing the magnetic absorbing piece, and a connecting hole is opened in the middle of the connecting piece. When the connecting piece is magnetically attracted to the magnetic piece, the connecting piece and the valve magnetically repel each other, so that the valve moves in the guide part against the opening and is positioned in the guide part, and the connecting hole communicates with the opening correspondingly, so that the external sound cavity is connected to the internal sound cavity cavity. The invention also provides a loudspeaker group and an external sound 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...
