The present invention relates to the technical field of electroacoustic products. Disclosed is a miniature speaker. The miniature speaker comprises an upper housing and a lower housing combined together. A vibration system and a magnetic circuit system are accommodated in the space defined by the upper housing and the lower housing. The upper housing is disposed close to the vibration system. The miniature speaker also comprises a hearing-aid voice coil. The hearing-aid voice coil is fixed to the upper housing and is located at the inner side of the upper housing. The miniature speaker of the present invention solves the problem of poor acoustics caused by collision of a lead wire of a vibrating voice coil with a hearing-aid voice coil of a miniature speaker in the prior art, and the miniature speaker of the present invention has good acoustic performance and a better hearing-aid effect.

A vibration apparatus includes a substrate, an elastic piece, a magnetic component and at least two coils. The substrate abuts on a display panel of a mobile terminal; the at least two cods are fixed on an inner side surface of the substrate; the inner side surface faces away from the display panel; the at least two coils are disposed coaxially; and axes of the at least two coils are perpendicular to the substrate.
