Definitions

  • the invention relates to a pop protection for microphones with a housing in which a electroacoustic transducer is housed and with a shell made of open-pore Foam, which, together with the housing, the electroacoustic transducer at least essentially completely enveloped.
  • the invention relates in particular but not exclusively microphones that have built in the pop protection, so inside their housing or their grille cover.
  • a shield is provided in the prior art, mostly made of foamed plastic (in the following text foam) around the membrane
  • foamed plastic in the following text foam
  • Embodiments are spherical or cube-like structures made of foam Microphones plugged in, this is particularly the case with microphones used for reports are used, an investigation showing that such push-on sleeves that often referred to as wind protection, not very effective.
  • Both real windbreakers that have foam sleeves and an exterior there are fur-like covering arranged above, but this is different, these devices are actually capable of wind noise and that similar to the wind noise prevent occurring popping or popping.
  • the pop protection covering is proposed to achieve these goals at least in the main speaking direction of the microphone at a distance of two from each other having to divide envelopes.
  • microphones that are preferably discussed from one direction (e.g. rod microphones in the axial direction)
  • the invention is based on the knowledge that conventional pop protection covers too if the wall thickness is increased, there is no noticeable improvement in the pop protection, but attenuated the sensitivity, directional characteristics and frequency response changed become. Compared to conventional pop protection covers, they can Wall thickness can be significantly reduced without the pop protection achieved being reduced.
  • a cover according to the invention designated in its entirety with 1 is not for a illustrated microphone thought that preferred and essentially in the direction of the arrow 2 is discussed.
  • Such microphones are particularly common in interviews but can also be used for other purposes.
  • the cover according to the invention consists of two foam parts 4 and 5, part 4 essentially corresponds to the cover according to the prior art, albeit with a change discussed below.
  • this foam part 4 according to the invention another, similarly designed foam part 5 is placed, whose most important surface when using the microphone is the end face 6, the is arranged like a screen between the speaker and the microphone.
  • Parallel there is an end face 7 of the foam 4, the two end faces 6, 7 Have a distance from each other and an air gap L in the main direction of the arrow 2 lies between the two surfaces. It is not so important that the outer surfaces of the front foam body 5 a closed air space in this Form area than the fact that the end faces 6 and 7 are spaced apart.
  • a detail is drawn from which a preferred connection between the two foam parts 4 and 5 emerges. It is about Enlargement of the adhesive surface and to facilitate centering by a bit Formation of the joint.
  • FIG. 2 A somewhat different embodiment is shown in FIG. 2.
  • a foam body 4 ' is essentially H-shaped in cross-section, in reality it is cylindrical with an integrally formed intermediate floor 7 ', instead of the entire covering in Fig. 1 only one end face 6 'is inserted into the foam body 4'.
  • the use with offset to facilitate centering and connection Provide wall thickness so that a stop for the end face 6 'in the foam body 4' is created.
  • the two foam bodies 4, 5 and 4 ', 6' can be made of different materials exist, this can be easily selected by a person skilled in the art knowing the invention. In this context, it should briefly refer to the physical mode of action Popp covers of this type are considered:
  • These covers are made of open-cell foam, in which the connections between the individual cavities sound paths of different lengths between two form opposite surfaces of such a foam body. When it hits a sound wave in the form of a shock front on one surface of the foam body now has the sound entering the foam body due to the different Length of the individual sound paths when exiting on the other side of the foam body no longer the character of a bump front, but the exit from the individual Channels are staggered.
  • the foam layers 4 and 5 consist of foam with 80 ppi (pores per inch), the "placeholder” made of foam with 20-40 ppi.
  • the open-pore currently used for shielding can be used as foam Foams are used, the mounting on the microphone is the same as in the state of the Technology, as well as the attachment of a protective grille if desired.
  • the two foam parts are connected to one another using suitable commercially available Adhesive that is matched to the foams used and the specialist are known in the field of foams and their use.
