Abstract: A blocking piece covering the sound hole of a loudspeaker module may be arranged at a position where the sound hole is located on the case of the loudspeaker module and covers the sound hole. The blocking piece may be made of a nonmetallic flexible net. The nonmetallic net-shaped blocking piece and the case may be formed integrally by injection molding. The loudspeaker module and the blocking piece covering the sound hole thereof in the present invention may provide good acoustic performance, high reliability, high space utilization rate and/or high production efficiency. The assembling method for the blocking piece covering the sound hole of the loudspeaker module further makes the assembling of the blocking piece convenient for operation, and improves the assembling efficiency and assembling quality.
