Portable loudspeaker
A portable loudspeaker includes a base and a speaker cap opposing the base. The base and speaker cap are interposed by a movable resonance portion. The movable resonance portion is formed in a storing state and a releasing state. The base has a resonance reflection portion to receive reverse resonance sound waves generated by a speaker. The movable resonance portion includes a first transmission channel to transmit the reverse resonance sound waves to the resonance reflection portion and a second transmission channel to transmit base sound waves generated by the resonance reflection portion from the reverse resonance sound waves towards the speaker cap. The speaker cap has a second audio outlet to output the bass sound waves.
