Wherein, the first battery 12 and the second battery 12a are connected in series, and the AUX interface 25 can be connected to an audio output device, such as a CD player, through a data cable; the charging interface 24 of this embodiment adopts the Micro-USB interface, and a plurality of function keys 23 include key, bluetooth on & off switch, light key, increase volume key and volume reduction key, two pilot lamps 26, and one of them is used for pilot lamp 26 to show bluetooth speaker's electric quantity state, and another pilot lamp 26 is used for showing bluetooth speaker bluetooth connection status.

For a mini-speaker, due to volume limitations, the speaker used cannot be too large, and is generally used with a speaker of 2 inches or less, so that, due to the small aperture of the speaker, the volume of air pushed by the speaker is small each time the speaker vibrates, and the low volume sensation is directly related to the volume of air pushed by the speaker, and thus, the natural defect of the mini-speaker results in the lack of bass. Set up vibrating diaphragm 4 for this, set up the vibrating diaphragm for this in pronunciation main part bottom, when loudspeaker work was sounded, loudspeaker vibration can lead to the air in the box to be compressed and expanded, and under the effect that atmospheric pressure changes, the vibrating diaphragm produced the vibration, promoted the air outside the box, just so can sound. Because the vibrating diaphragm can be designed at the bottom or the rear part of the sound box, the vibrating area of the vibrating diaphragm can be larger. Therefore, the volume of the pushing air is increased, the bass volume is greatly improved, meanwhile, the caliber of the passive vibrating diaphragm is increased, the frequency of a resonant product of the passive vibrating diaphragm can be reduced, and the sound box can obtain better bass diving depth when sounding. Through setting up first vibrating diaphragm 13 and second vibrating diaphragm 13a, rely on great vibrating diaphragm, even if use little loudspeaker, mini audio amplifier also can obtain better bass effect.
