The invention discloses loudspeaker die set, and relates to the technical field of electroacoustic products. The loudspeaker die set comprises a housing in which a single loudspeaker body is contained; the single loudspeaker body comprises a vibrating system and a magnetic circuit system; an inner cavity of the whole die set is divided into two cavities, namely, a front vocal cavity and a rear vocal cavity, through the single loudspeaker body; a sound absorbing material is positioned in the rear vocal cavity; a separating structure for separating the sound absorbing material and the single loudspeaker body is also arranged in the rear vocal cavity; the whole rear vocal cavity is divided into a filling area and a non-filling area through the separating structure; the sound absorbing material which is foaming material is positioned in the filling area; the sound absorbing material is filled by foaming the foaming material and fully filled in the filling area. With the adoption of the loudspeaker die set, the technical problems of poor consistency and high production cost of the loudspeaker die set product in the prior art can be solved; the loudspeaker die set is high in acoustic performance, high in production efficiency, small in production cost, and high in product consistency.
