How are our Ganymede MEMS speakers connected mechanically?
Sealing the front from back side of the speaker is critical to obtain the best acoustic output. This can be achieved by two methods:
- Gluing the speaker into the housing. In this case the glue can be applied around the speaker or on the cover. Care must be taken to:
- Obtain a 100% sealed glue-line
- Not cover critical parts with glue spill, like membrane, back opening or electric contacts
- Using a gasket between housing and cover. In this case the speaker must be pressed from the back side onto a gasket in the housing. This can be done by a simple mechanical part or via pogo pins / spring contacts also used for the electrical connection.
While in the final application the usage of glue may be desired due to cost, the use of a gasket offers the advantage of compensating mechanical tolerances and the possibility of non-destructive disassembling.
