- the neck is hollow and advantageously has an approximate
- the nozzle and the inner housing shell can be made in one piece. The nozzle is then stable with the
- Combination components of inner housing shell and nozzle is particularly easy to accomplish.
- the nozzle can be advantageously carried out in two parts.
- the nozzle can be in the
- a two-part design of the nozzle offers
- Socket halves can be easily manufactured and assembled during assembly to the neck.
- the cutting line or a sectional plane of the nozzle runs in an axial direction of the nozzle.
- the axial direction extends along a cavity enclosed by the connecting piece.
- the nozzle advantageously has a
- tubular center piece whose outer periphery is adapted to a circumference of the recess of the inner housing shell.
- Inner housing shell, the neck according to the invention arranged at opposite ends of the center piece and a larger outer circumference than the middle piece having bearing elements, wherein the contact elements on
- the Investment elements can advantageously with
- the nozzle can be fixed to the inner housing shell.
- the neck can be fixed by pressing firmly into the recess in this releasably.
- the nozzle is guided from the inside of the inner housing shell through the recess and on the intended
- This embodiment has the advantage that the nozzle sits very securely in the recess, but the fixation by removing the ring is still easily solvable.
- the neck at least one
- the Sound channel has.
- the sound channel is used in the
- the nozzle has an outer sound channel at its end, which is aligned with the auditory canal when used as intended, which opens into at least two sound channels in the interior of the nozzle, which exit from the end of the nozzle facing the inside of the housing when used as intended.
- the nozzle has an outer sound channel at its end, which is aligned with the auditory canal when used as intended, which opens into at least two sound channels in the interior of the nozzle, which exit from the end of the nozzle facing the inside of the housing when used as intended.
- Sound signals can be routed separately to the nozzle and then merged into this.
- the invention further comprises an acoustic device with a sound transducer in a housing.
- the housing is preferably designed according to the embodiments described in more detail above.
- the sound transducer is a component that is adapted to receive and reproduce sound signals.
- At least one sound driver is preferably present in the sound converter.
- the sound driver converts electrical
- Signals in sound signals to.
- a single or multi-way system is provided in the sound converter.
- there are several sound drivers in the sound converter the
- Frequency bands are designed. This results in a particularly good sound reproduction.
- the outputs of the different sound drivers should be connected to the inner sound channels of the nozzle.
- the different sound signals emitted by the sound drivers become inside the socket
- a replaceable, passive noise filter can be provided. Such a noise filter provides additional protection against external sound effects.

- Fig. 9 shows the nozzle (8) in a schematic
- the neck has an outer
- Sound transducer produces sound in the ear canal.
- the sound is first picked up by two inner sound channels (10). These are connected inside the housing (1) with a sound transducer, not shown.
- two sound drivers are provided, which represent separate sound sources.
- the sound generated by the two sound drivers is supplied to the inner sound channels (10) separately and combined in the outer sound channel (9). Because the connecting piece (8) is wider in the region of the inner sound channels (10) than in the region of the outer sound channel (9), it can not slip out of the inner housing shell (5) in the direction of the auditory canal.
