Loudspeaker monomer and loudspeaker module accepting same

The utility model discloses a loudspeaker monomer and a loudspeaker module accepting the same, and relates to the electroacoustical product technology field. The monomer comprises a monomer shell and a monomer front cover combined as one, a vibration system and a magnetic circuit system are accepted in a cavity defined by the monomer shell and the monomer front cover, and the back end edge part of the monomer shell is equipped with a stepped structure. The stepped structure comprises a stepped surface and a stepped side surface used for connecting a back end face of the monomer shell and the stepped surface, the stepped surface is equipped with a first sound aperture for communicating an inner cavity of the monomer and the world outside the monomer, and the above loudspeaker monomer is accepted in a module shell. The loudspeaker monomer of the utility model has the advantages of high acoustic performance, long service life, etc., thereby improving the acoustic performance and service life of the loudspeaker module accepting the loudspeaker monomer.
