Abstract

The embodiment of the invention discloses an installation device of a microphone assembly, which is applied to the technical field of microphone. A mounting device comprises a bottom die for limitinga back polar plate in the microphone assembly at a preset distance from an opening of an annular cavity in the microphone assembly, the bottom die is embedded into the opening, the upper surface of the bottom die is higher than the preset distance of the opening, the back polar plate is embedded into the cavity of the annular cavity, and the lower surface of the back polar plate makes contact withthe upper surface of the bottom die. The embodiment of the invention further discloses a novel microphone assembly, an installation device of the sensor assembly and the novel microphone assembly, and the yield of microphone assembly can be improved.

Description

technical field [0001] The invention belongs to the technical field of microphones, in particular to a mounting device for a microphone assembly and a novel microphone. Background technique [0002] The microphone is an energy conversion device that converts sound signals into electrical signals. In the automatic assembly process of the microphone, there is a step of embedding the back plate into the cavity, which requires the back plate to be embedded and pressed to the lower plane of the plastic cavity. . [0003] However, due to the characteristics of plastic processing, the two ends of the ring-shaped cavity are actually slightly bell-shaped. After the back plate is embedded in the bottom of the plastic cavity, the back plate is just at the position of the bell mouth. At this time The fit between the back plate and the plastic cavity is a loose fit, not a tight fit. At this moment, under the vibration of the automatic production line, the back plate will fall off from t...
