Definitions
- the present invention relates to a microphone and an isolation part for a microphone.
- Microphone capsules are usually provided in microphones and can have an electrode and a membrane.
- the electrode must be isolated from the membrane.
- a defined distance between the membrane and the electrode is desirable.
- an insulating part and a separate spacer ring are provided for this purpose, both of which are arranged accordingly between the electrode and the membrane in the microphone capsule.
- the required spacer ring is typically punched out of a film, but this does not guarantee that the spacer rings are cleaned properly, since spacer rings adhere to one another due to the cleaning liquid, so that dirt residues, among other things, cannot flow off as desired.
- the invention is based on the idea of manufacturing an insulation part and a spacer ring in a microphone capsule as a single part, for example by injection molding the spacer ring onto the insulation ring.
- a microphone with a microphone capsule housing, a membrane, an electrode and an insulation part is provided, which is arranged between the membrane and the electrode in the microphone capsule housing, the insulation part having a spacer ring.
- the insulation part and the spacer ring Due to the design of the insulation part and the spacer ring as a single element or part, only one element has to be inserted into the microphone capsule instead of two elements, which leads to a more effective manufacturing process. The cleaning of the parts is also improved because sticking together due to the cleaning liquid is avoided.
- the spacer ring is injection molded onto the insulation part. This enables an economical and effective production of the resulting combination part.
- FIG. 1 shows a plan view of an insulation part with a spacer ring
- FIG. 2 shows a sectional view along the section AA of the insulation part of FIG. T
- FIG. 3 shows an enlarged sectional view Z of the sectional view of FIG. 2.
- Figure 1 shows a plan view of an insulating ring 1 for isolating a membrane from an electrode in a microphone capsule housing.
- a spacer ring 2 is provided on the outer edge of the insulating ring. This spacer ring 2 serves to provide a defined distance between the membrane and the electrode.
- the spacer ring 2 is injection molded onto the insulating ring 1 in an injection molding process.
- the injection molding process can be a one- or two-component injection molding process. If the spacer ring 2 is to be made of the same material as the insulating ring 1, a one-component injection molding process can be used. However, if the spacer ring 2 is to be made of a different material than the insulating ring 1, then a two-component injection molding process can be used.
- FIG. 2 shows a sectional view along the section A-A of the insulating ring from FIG. 1. It can clearly be seen here that the spacer ring 2 has a greater thickness than the insulating ring 1.
- Figure 3 shows a partial sectional view Z of the sectional view of Figure 2.
- the spacer ring 2 has a first end 2c, which preferably has a bevel of 45 °. Furthermore, the spacer ring 2 has a further end 2a, which points towards the interior of the spacer ring.
- the spacer ring 2 By spraying the spacer ring 2 onto the insulating ring 1, a new element is produced which has to be inserted into the microphone capsule for assembly. This is advantageous because now it is no longer two parts, but only one part to ensure the insulation and the defined distance between the membrane and the electrode in the microphone capsule is required.
- the insulating ring 1 with the spacer ring 2 can be automatically stacked in a microphone capsule housing. In this way, both automatic and manual stacking can be considerably simplified and the corresponding costs can be reduced.
- the spacer ring can have a thickness of 30 ⁇ m, for example. However, this thickness can vary according to the desired application and the microphone capsule.
