Abstract (en)
[origin: CN204168461U] The utility model relates to a loudspeaker, which comprises a housing (10) and at least one acoustic transformer (38, 40) arranged in the housing. According to the technical scheme of the utility model, a plurality of channels (42, 44 and 46) are extending in the housing (10) while being separated from one another. By means of the channels, sound waves can be arranged at the front/rear side of the at least one acoustic transformer (38, 40) by means of the at least one acoustic transformer (38, 40). In this way, the reaction force of sound waves emitted from one part of a film onto the other part of the film can be avoided. Therefore, the distortion of the loudspeaker is reduced.
