The above discloses a prevent loudspeaker and microphone shake structure altogether for intelligent device. According to the structure, the independent first shockproof assembly and the second shockproof assembly are arranged, so that the loudspeaker assembly and the circuit board microphone assembly are respectively and elastically isolated. The first vibration-proof component effectively absorbs vibration generated when the loudspeaker works and prevents the vibration from being directly transmitted to the shell component, and the second vibration-proof component provides buffer for the circuit board microphone component, so that the possibility that the vibration affects the microphone through mechanical conduction is greatly reduced by double protection. The fixed component passes through the circuit board microphone component and the second shockproof component to be fixed on the shell component, so that the shock conduction caused by rigid connection is avoided while the stable installation of the components is ensured, and the shockproof effect is further optimized. Due to the structural design, noise generated by loudspeaker vibration can be remarkably reduced in the voice interaction process of the equipment, and the accuracy and stability of voice recognition are greatly improved.
