Abstract

A speaker includes a speaker driver and a speaker back cover. The speaker driver has a basket at its rear side. The speaker back cover is sealed and fixed to the basket and includes two casing parts which are relatively movably or rotatably connected and form a resonance space at the rear side of the speaker driver. Each casing part has a channel structure with an opening. The two channel structures are connected so that the resonance space is connected to the outside of the speaker back cover through it. The two casing parts can be moved or rotated relative to each other to adjust a channel path length of the two channel structures from their inner opening to their outer opening.
