Loudspeaker horn

According to the loudspeaker provided by the utility model, the main shell, the magnetic source module and the vibration module are arranged, and the magnetic source module comprises the aluminum sheet and the copper cap, so that the distortion rate of the loudspeaker can be greatly reduced when the loudspeaker vibrates to produce sound; besides, as the air pipe is arranged in the main shell, when the loudspeaker vibrates to produce sound, air flow can be generated in the air pipe, the air flow has a noise reduction effect, the sound production quality is prevented from being influenced by overlarge noise of the environment where the loudspeaker is located, and the stability of the loudspeaker is improved. 本实用新型的扬声喇叭，通过设置主壳、磁源模组及振动模组，由于磁源模组包括铝片和铜帽这两大结构件，能够在扬声喇叭振动发声时，让扬声喇叭的失真率大大降低；此外，由于主壳内设置有风管，当扬声喇叭振动发声时，风管内会产生气流，气流能够降噪作用，防止扬声喇叭因所处的环境噪音过大而影响发声质量，提高扬声喇叭的稳定性。
