Definitions

  • the present invention relates to a dynamic sound transducer and a listener.
  • a voice coil is provided in the region of the diaphragm bead, with coil wires being used to contact the voice coil.
  • the coil wires thus connect the diaphragm edge and the voice coil.
  • the provision of such coil wires in the production of dynamic transducers manufacturing technology very complex and can lead to rejects of the sound transducer, for example, when clutter or coil wire tears are present. Since the coil wires are typically laid on only one side of the membrane, an asymmetric mechanical force can be exerted on the voice coil, so that an undesirable tumbling of the membrane may be present.
  • US 2004/0141629 A1 shows a dynamic transducer with a membrane, wherein a voice coil is arranged in the region of the diaphragm bead. At the edge of the membrane two electrodes are provided, which are connected to the voice coil. The connecting portions between the electrodes and the voice coil are coated with an electrically conductive polymer layer.
  • US 6,320,970 B1 shows a dynamic transducer with a membrane system, which has a membrane with a bead and an inner and outer membrane pad. Furthermore, the dynamic sound transducer has a voice coil.
  • US-A1-2005 / 0238197 discloses a dynamic transducer whose membrane system has first and second beads with inner and outer membrane pads.
  • GB-A-2347044 shows a transducer whose membrane consists of a first and second bead. In one embodiment, at least one of the edges of the membrane is bonded to a soft material and secured thereto above the chassis.
  • Dynamic transducers also typically include a diaphragm having a crimp and a dome.
  • the upper limit frequency of such a dynamic sound transducer depends on the size of the surface which emits sound. The larger the sound-radiating surface, the lower the upper limit frequency of the frequency response. If the sound emitting area is increased, an audio signal having a reduced distortion can be reproduced.
  • a dynamic transducer is provided with a membrane system having a membrane with a hole in the center, first and second beads, and inner and outer membrane pads. Furthermore, the sound transducer has a voice coil, which is arranged on a coil seat in the region between the first and second bead.
  • the membrane of the membrane system is disposed in a chassis and the second bead is secured to the inside of the chassis via the inner membrane pad and the first bead is attached to the exterior of the chassis via the outer membrane pad.
  • the membrane is designed stiff in the coil seats and is made softer towards the inner and outer membrane pad.
  • the present invention also relates to a sound transducer having a diaphragm system having first and second beads and a voice coil disposed in the region between the first and second beads.
  • the invention relates to the idea of providing a dynamic sound transducer with a membrane which is (half-sidedly) coated with a conductive coating.
  • the center of the membrane can have an insulating strip, which has no conductive coating.
  • the surface of the conductive coating can be divided into two mutually insulated sections.
  • the coil wires of the coil can be cut short and be attached or glued in an immediate proximity to the coil electrically conductive to the membrane, so that an electrical connection with the membrane edge on the conductive layer of the membrane is provided.
  • the chassis of the dynamic transducer may have two conductive lines, with the membrane having the conductive coating glued to the chassis so that the conductive coating of the membrane has a conductive contact with the chassis.
  • Fig. 1a shows a plan view of a diaphragm system of a dynamic sound transducer.
  • the membrane 10 is connected to a voice coil 20 and embedded in a chassis 30.
  • the membrane 10 has on its one side two metallized surfaces 11 and an insulating, ie not electrically coated portion 12 between the two metallized surfaces 11.
  • the coil wires 25 of the voice coil 20 are respectively adhesively bonded to one of the metallized surfaces 11 or conductively connected to the metallized surfaces 11.
  • two contact elements 15 are provided, which are conductively connected to the two metallized surfaces 11, for example, by gluing.
  • the two electrical contact elements serve to couple the voice coil via the electrically conductive surfaces with an electrical circuit G, which serves, for example, to apply a signal to the voice coil.
  • Fig. 1b shows a sectional view of the membrane system of Fig. 1a ,
  • the diaphragm 10 is disposed in the chassis 30 and has a voice coil 20 with a coil wire 25.
  • One side of the membrane preferably the underside, is coated with an electrically conductive layer 11 in a sputtering process, for example.
  • an electrically conductive layer 11 may be formed, for example, by sputtering Al (a few angstroms) and sputtering AU (about 2000 angstroms).
  • sputtering Al a few angstroms
  • sputtering AU about 2000 angstroms
  • the connecting wires 25 of a voice coil 20 are then bent inward, the insulation of the connecting wires of the voice coil are thermally stripped in the vicinity of the coil (at about 380 °) and shortened.
  • the coils 25 may then be placed and secured to the membranes 10 in a conventional manner.
  • the two stripped and shortened connecting wires 25 of the voice coil 20 are electrically conductively connected or glued to one another with the two contact surfaces 11 of the electrically conductive layer.
  • the chassis 30 of the dynamic transducer has at the membrane seat two wires 15 which are connected to a printed circuit board in the dynamic transducer.
  • the membranes 10 are inserted into the chassis 30, and the wires are contacted accordingly.
  • the membrane can be glued or attached to the chassis.
  • a dynamic sound transducer having a nominal resistance which is slightly larger than the nominal resistance of the coil can be obtained.
  • the contact has only a contact resistance of a few ohms.
  • the insulating section 12 may preferably be designed smaller than the first and second electrically conductive surface 11. This allows easy and locally flexible contacting of the wires 15 since one of the wires 15 can be connected to the first conductive surface at any location, preferably near the outer edge. The other wire is connected to the second conductive surface accordingly.
  • one side of the membrane is provided with a central strip-shaped insulation section 12 and the remaining approximately semicircular surfaces of one side of the membrane are coated with the first and second electrically conductive surfaces. By a very large first and second electrically conductive surface and a low electrical resistance between the wires 15 and the leads 25 can be achieved.
  • Such a dynamic sound transducer may preferably be used in a headphone, a handset or a headset.
  • Fig. 2a shows a sectional view of a dynamic transducer according to the invention.
  • the dynamic sound transducer has a chassis 130, a membrane 110 with two beads 110 a, 110 b, a voice coil 120 and a magnet system 140.
  • Fig. 2b shows a perspective schematic view of a dynamic transducer according to Fig. 2a ,
  • the dynamic transducer has two beads, but no dome, ie in the middle of the membrane, a hole 150 is provided.
  • Fig. 2c shows a further perspective view of a dynamic transducer of Fig. 2a , In particular, the corresponding membrane system is shown here.
  • the membrane system has an outer membrane pad 111 and an inner membrane pad 112 and a passage or hole 150. Between the outer membrane support 111 and the coil seat 122 is a first bead 110a and between the coil seat 122 and the inner membrane pad 112, a second bead 110b is provided.
  • the invention thus relates to the idea of reducing or avoiding occurring distortions by increasing the membrane area, wherein an upper limit frequency is maintained. Furthermore, a dynamic sound transducer is provided, which has a reduced resonance frequency, so that such a sound transducer can be used as a broadband converter. To reduce the vibration modes, a higher circumference is provided relative to the calotte converter.
  • the invention thus relates to the idea to provide a dynamic transducer with two beads 110a, 110b, but without dome. The two beads 110a, 110b are fastened inside and outside on the chassis 130 of the dynamic transducer.
  • a coil 120 for driving the membrane is provided at the center 122 between the outer and inner beads 110a, 110b.
  • the membrane 110 In the region of the membrane where the coil is arranged, ie on the coil seat 122, the membrane 110 is made rigid, which can be achieved by a corresponding contour of the membrane. The membrane is further softened toward the edge regions, ie the membrane supports 111, 112. Due to the fact that the membrane does not have a uniform rigidity, the size of the sound-radiating surface depends on the frequency. At low frequencies, a large part of the beads 110a, 110b vibrates homogeneously with the coil 120 and thus represents a large sound radiating surface. However, when the frequency is increased, only a near portion of the coil seat 122 vibrates, so that the sound radiating surface is reduced. Thus, high frequency components can be emitted accordingly.
  • the upper limit frequency of the dynamic sound transducer is set outside the listening area. As the active sound radiating surface of the dynamic transducer is increased, lower strokes are allowed to produce the sound signals, which can reduce distortion.
  • the dynamic transducer has a Ringradiator with a vapor-deposited foil (Duofol) in order to reduce the resonance frequency.
  • a broadband converter can be provided, which can be used for example in an open headphone.
  • the membrane of the dynamic transducer can be steamed. Due to the enlarged circumference of the membrane, vibration modes can propagate more poorly. Thus, a uniform amplitude and frequency response can be obtained.
  • Fig. 3a shows a perspective view of a magnetic ring for a dynamic transducer.
  • the magnetic ring 240 according to Fig. 3a For example, in the dynamic transducer according to Fig. 2a or in the magnet system 140 of the dynamic sound transducer of Fig. 2a be used.
  • Fig. 3b shows an enlarged portion B of Fig. 3a
  • the magnetic ring 240 has a substantially U-shaped cross section, wherein no complete magnetic ring, but only magnetic segments 241 are provided in the U-shaped magnetic ring. Thus, 241 air gaps 242 are provided between the magnet segments.
  • the magnet system For venting the air gap of the magnet system, the magnet system is designed annular, with no complete magnetic ring, but only magnetic segments 241 are provided.
  • the resulting air gaps 242 between the individual magnet segments 241 thus allow the air to escape in the region of the magnet system.
  • the otherwise usual compressions of the air cushion in the region of the air gap of the magnet system can be avoided.
  • unwanted acoustic springs can be avoided by the compression of the air cushion.
  • airflows between the various regions of a membrane system, such as between a crimp and a dome region, or between an inner and an outer crimp (such as in FIG Fig. 2a to 2c shown) are prevented by the air gap.
  • Fig. 4 shows a schematic sectional view of a headphone.
  • the headphone has a sound transducer 300, ear pads 400, and a baffle 600.
  • the headset is placed over ear 700 by ear cushions 400.
  • the headphone according to the fourth embodiment has a curved baffle 600.
  • the flat baffle according to the prior art and its corresponding sound transmission serves to control the acoustic path to the outside world and the back of the sound transducer.
  • grids or similar elements are often placed on the back of the transducer. Through these elements However, unwanted reflections may occur, which may affect the acoustic reproduction of the transducer.
  • the baffle 600 is configured bent and at the same time constitutes an outer wall or sleeve for the headphones. Thus, no undesired acoustic effects are created by an additional protective housing. By means of the curved baffle 600, a reflection-free termination to the outside world can thus be achieved.
