Housing

Abstract

A housing is provided for an acoustic device which is worn in the ear. The housing includes two housing shells, which can be connected with one another along a housing connecting line. The housing connecting line extends at most sectionally in one plane. The housing connecting line is predefined such that the housing shells are configured without undercuts. An outer shape of the housing is adapted to a human ear shape such that the housing lies form-fittingly on an inner side of a tragus and on an inner side of a counter-ledge or antihelix of a human auricle, if the housing is arranged in the auricle.

7. Housing according to claim 6, wherein the curvature of the housing connecting line, in the at least one region, is, in sections, zero, and constantly changes in the remaining extension.

8. Housing according to claim 1, wherein the housing shells are an inner housing shell and an outer housing shell, wherein the inner housing shell is facing an ear canal, and the outer housing shell is at least, in sections, visible from the outside if the housing is arranged in the auricle, wherein the outer housing shell has a planar shape in a region visible from outside.

9. Housing according to claim 8, wherein the outer housing shell comprises a plug recess adjacent to the connecting line.

10. Housing according to claim 8, wherein the inner housing shell comprises a recess facing the ear canal, when used as intended.

11. Housing according to claim 10, wherein an adaptor is arranged on the recess for the placement of an earpiece.

12. Housing according to claim 11, wherein the adaptor is configured in two pans.

13. Housing according to claim 11, wherein the housing includes a retaining ring, with which the adaptor is fixable to the inner housing shell.

14. Housing according to claim 11, wherein the adaptor comprises at least one sound channel.

15. Housing according to claim 14, wherein the adaptor comprises an outer sound channel on its end oriented toward the ear canal, when used as intended, which sound channel opens into at least two sound channels in the interior of the adaptor, which sound channels emerge out of the end of the adaptor facing towards the inner side of the housing in the intended use.

16. Acoustic device with an audio driver in a housing according to claim 1.

17. Acoustic device according to claim 16, wherein an exchangeable, passive noise filter is provided in the housing.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) Further advantageous configurations of the housing according to aspects of the invention are explained in greater detail based on the exemplary embodiments represented in the drawings.

(2) Shown are in:

(3) FIGS. 1 to 3 different schematically-illustrated views of a housing according to an aspect of the invention,

(4) FIGS. 4 to 7 different schematically-illustrated views of a housing according to an aspect of the invention, wherein the housing shells have different colors,

(5) FIG. 8 a schematic view of a housing according to an aspect of the invention with an adaptor, and

(6) FIG. 9 a schematic view of the adaptor.

DETAILED DESCRIPTION

(7) FIGS. 1 to 3 show different schematically-illustrated views of a housing (1) with two housing shells (2), which are connected with one another along a housing connecting line (3). The housing connecting line (3) does not extend in one plane, so that the housing shells (2) can be joined together without undercuts along the housing connecting line (3).

(8) An outer shape (4) of the housing (1) is adapted to a human ear shape such that the housing (1) can be arranged form-fittingly in a non-illustrated auricle of a human ear. In this way, the wearing comfort of the housing can be significantly improved.

(9) The housing shells (2) are an inner housing shell (5) and an outer housing shell (6). The inner housing shell (5) is facing a non-illustrated ear canal, and the outer housing shell (6) is at least in sections visible from outside if the housing (1) is arranged in the auricle. The outer housing shell (6) has a planar shape in a region (7) visible from outside. An individual imprint can, for example, be applied onto this region (7).

(10) In the housing (1) schematically represented in FIGS. 4 to 7 in different views, the housing shells (2) have different colors.

(11) FIG. 8 shows an embodiment of the housing (1) with an adaptor (8). The adaptor (8) and the inner housing shell (5) are configured in two parts here. In order to fix the adaptor (8) in the inner housing shell (5), this adaptor is enclosed by a retaining ring (11). It is thereby avoided that the adaptor (8) unintendedly slips into the housing (1). The adaptor (8) serves for the transmission of sound into the ear canal. To that end, an outer sound channel (10), which can be discerned on the adaptor (8), is provided.

(12) FIG. 9 shows the adaptor (8) in a schematic view. The adaptor (8) has an outer noise channel (9), which guides the noise generated by an audio-transducer, not shown, into the ear canal. The sound is initially received by two inner sound channels (10). These channels are connected, in the interior of the housing (1), with an audio-transducer (100). Two audio drivers (200) are provided on the audio-transducer (100), which audio drivers constitute separate sound sources as seen schematically in FIG. 8. The sound generated by the two audio drivers is separately supplied to the inner sound channels (10) and is merged in the outer sound channel (9). By virtue of the fact that the adaptor (8) is wider in the region of the inner sound channel (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 ear canal. In order to prevent a slipping of the adaptor (8) into the housing, a retaining ring, not shown in FIG. 9, can be provided on the adaptor (8). As seen schematically in FIG. 8, a replaceable, passive noise filter (300) can also be provided in the housing (1) of the acoustic device.
