Definitions

  • the present invention relates to a portable device for transmitting sound with a Housing and at least one sound transmission means, wherein the sound transmission means is arranged on the body of a person such that a sound transmission path from Sound transmission means through the Eustachi tube to the person's ear bones.
  • DE 196 09 554 C1 Such a device is known from DE 196 09 554 C1.
  • DE 196 also describes 09 554 the basic method of transmitting sound using a sound transmission source, which is placed directly on the body of a person, so that there is a direct sound transmission path from the sound transmission medium via the Eustachi tube to the ossicles of the person. This results in a particularly sound-intensive transmission of tones emitted by the sound transmission means.
  • a disadvantage of the known generic devices for transmitting sound is, however, that the quality of the sound transmission, and thus the acoustic quality, is only very poor is.
  • a portable device for transmitting sound according to the invention has at least one Sound transmission means, each of at least one in the direction of a body one Person openly trained, tubular device is surrounded, so that the tubular device a sound space between the sound transmission means and the body of the person trains. Due to the additional, newly created sound space between the sound transmission means and the person’s body surprisingly has improved sound transmission, and thus improved acoustics when transmitting sound from the sound transmission means over the Eustachi tube to the person's ossicles.
  • the tubular device has a circular shape or elliptical or rectangular or square or triangular or polygonal or irregular cross-sectional shape. It is also possible that the shape of the cross section of the tubular device in approximately the geometric configuration of the housing of the invention Device corresponds. This ensures that the tubular device is always close to the body. In addition, the tubular device fits together as a single element easily in the design of the other elements of the portable device, so that the device according to the invention is also visually attractive.
  • the tube-like device consists of an elastic one Material, for example made of plastic. Due to the elasticity of the tubular device the concern or liability of the device according to the invention or the tubular device on the body increased so that a tightly sealed Sound space is created. The closer the connection between the tubular device and the Body, the better the sound transmission or the resulting acoustics.
  • the wall thickness of the tube-like device can range between 0.5 and 4.0 cm. This results in a correspondingly large contact surface of the tubular device on the body with the advantages described.
  • the cross-sectional area of the of the tube-like device formed sound space larger than the corresponding cross-sectional area of the sound transmission means. This advantageously results in an increase in volume of the resulting sound space with a corresponding improvement in sound transmission.
  • the tube-like device can point towards the housing End in the area of that not overlaid by the cross-sectional area of the sound transmission means Sound space have a flat support element. This support element serves on the one hand to stabilize the tubular device and on the other hand for an intimate connection with the housing of the portable device.
  • FIG. 1 shows a schematic side view of the portable device 10 according to the invention for the transmission of sound.
  • the portable device 10 has a housing 12 a sound transmission means 28 (see FIG. 2).
  • the housing 12 consists of one Base element 14 and a cover element 16, which by means of one or more first Fastening means 20 are releasably connected to one another.
  • the holding device 18 has one or several receiving devices 36 for receiving a sling, a belt or the like. It is thus possible to position the device 10 on a person's body.
  • FIG. 2 shows a view from below of the device 10 for transmitting sound.
  • the tube-like device 26 has a sound space 30 between the sound transmission means 28 and the body of the person (not shown).
  • the shape of the cross-section of the tubular device 26 is approximately the geometric Design of the housing 12 corresponds to the device 10.
  • the tubular device 26 has any other regular or irregular cross-sectional shape having.
  • the tube-like device 26 consists of an elastic material, in particular plastic.
  • the wall thickness of the tube-like Device 26 is in the range between 0.5 and 4.0 cm.
  • the sound transmission medium 28 is a speaker in the embodiment. But it is also possible that Sound transmission means 28 is designed as a resonator.
  • the cross-sectional area of the tube-like device 26 formed sound space 30 is larger than the corresponding cross-sectional area of the Sound transmission means 28.
  • the tube-like device 26 points in the direction of the housing 12 facing end 34 (see FIG. 1) in the region of the cross-sectional area of the sound transmission means 28 superimposed sound space 30 a flat Support element 32 on.
  • the holding element 18 is in the illustrated embodiment by means of of the second fastening means 22 rotatably mounted on the housing 12.
