A method for mounting an electroacoustic component on a PCB comprising the steps of: separately constructing a housing of the electroacoustic component, the housing comprising a shell seat and a base seat which are separate and then combined into a single body, and a plurality of sound producing components being pre-installed in the shell seat, and the base seat being pre-installed and comprising at least two conducting terminals; adhering the base seat to the PCB, so that the at least two conducting terminals on the base seat and at least two contacts on the PCB adhere to each other and are electrically connected in a reflow oven; and combining the shell seat and the base seat, so that the shell seat comprising the plurality of sound producing components is combined with the base seat adhered to the PCB outside the reflow oven into a single body, and the at least two conducting terminals being electrically connected to at least one of the plurality of the sound producing components to be configured to be attached to the electroacoustic component on the PCB, wherein the base seat is made of a heat-resistant plastic, and the shell seat and the sound producing components are excluded from being made of the heat-resistant plastic, wherein one end of the shell seat is formed with a connecting part, one end of the base seat forms a pair of docking sections for coupling the connecting part, and the shell seat and the base seat can be combined with each other at the outside of the reflow oven into a single body, by means of the combination of the connecting part and the docking sections such that the at least two conducting terminals are electrically connected to at least one of the plurality of sound producing components. separately constructing a housing of the electroacoustic component, the housing comprising a shell seat and a base seat which are separate and then combined into a single body, and a plurality of sound producing components being pre-installed in the shell seat, and the base seat being pre-installed and comprising at least two conducting terminals; adhering the base seat to the PCB, so that the at least two conducting terminals on the base seat and at least two contacts on the PCB adhere to each other and are electrically connected in a reflow oven; and combining the shell seat and the base seat, so that the shell seat comprising the plurality of sound producing components is combined with the base seat adhered to the PCB outside the reflow oven into a single body, and the at least two conducting terminals being electrically connected to at least one of the plurality of the sound producing components to be configured to be attached to the electroacoustic component on the PCB, wherein the base seat is made of a heat-resistant plastic, and the shell seat and the sound producing components are excluded from being made of the heat-resistant plastic, wherein one end of the shell seat is formed with a connecting part, one end of the base seat forms a pair of docking sections for coupling the connecting part, and the shell seat and the base seat can be combined with each other at the outside of the reflow oven into a single body, by means of the combination of the connecting part and the docking sections such that the at least two conducting terminals are electrically connected to at least one of the plurality of sound producing components.
