Definitions

  • the invention relates to a loudspeaker system.
  • Loudspeaker systems or, according to another common name sound converters are used to convert electrical energy into sound waves.
  • membranes are usually set into mechanical vibrations.
  • Loudspeakers are used in loudspeaker boxes, radios, televisions, radio receivers, handheld radios, test receivers, cell phones and MP3 players.
  • EP 2 736 269 A1 published May 28, 2014, discloses in Figure 4 a waterproof loudspeaker system with a loudspeaker which consists of a housing and a flat membrane, the housing of the loudspeaker being covered with a polymer foam.
  • the invention is based on the object of expanding the possible uses of loudspeaker systems, especially in mobile devices.
  • an exemplary loudspeaker system has an oval basic shape.
  • the top is essentially formed by the membrane 1, which consists of an approximately 3 mm thick flat plate made of hard-foamed PVC (FOREX).
  • Drivers mounted in a freely floating manner behind the diaphragm 1 enable the user to come into contact with the diaphragm and thus also feel the sound pressure and thus make music perceptible and not just audible.
  • the membrane 1 is connected to the housing 3 by means of a rubber bead 2.
  • This is advantageously made from extruded polypropylene, which gives it high strength and low weight.
  • the elasticity of the material enables control elements in the form of push buttons 4.5 to be inserted into the To integrate housing 3, as they are provided in the embodiment on the underside of the speaker system.
  • the membrane 1 also becomes a control surface by means of pushbuttons and magnetic switches embedded on the inside of the device.
  • a particularly advantageous embodiment of the loudspeaker system according to the invention is obtained when a coupling process with other loudspeaker systems can be triggered by magnetic switches integrated in the membrane. This coupling can take place, for example, via Bluetooth or Wifi and several speaker systems can then play the same music synchronously.
  • This "Pick my Tune” functionality can be triggered, for example, by joining two loudspeaker systems on their membrane side.
  • the production of the housing 3 from extruded polypropylene provides a high degree of flexibility in the design of the housing. Due to the low weight of the material, the housing 3 can also serve as a floating body. Its elasticity has the effect that the internal sound pressure generated by the membrane 1 is reproduced via the housing 3 and, when used on a water surface, the housing transmits sound waves to the water.
  • housing 3 is coupled to other hollow bodies such as empty boxes or plastic containers by touching them, sound is transmitted to them, thereby producing a better reproduction of low frequencies.
  • the music being played can be made perceptible, which can support relaxation techniques and therapies, for example.
  • Fig. 2 shows a cross-section through an exemplary loudspeaker system with membrane 1, rubber surround 2, housing 3 and a frame for the control electronics for the loudspeaker which in particular includes an accumulator including charging interface, as well as signal processor unit, acoustic converter and communication units based on Bluetooth and WiFi with a signal source but also with other speaker systems.
  • an accumulator including charging interface, as well as signal processor unit, acoustic converter and communication units based on Bluetooth and WiFi with a signal source but also with other speaker systems.
  • the combination of the membrane 1 according to the invention made of a flat plate made of a hard-foamed plastic with a housing made of extruded polypropylene enables particularly robust, versatile loudspeaker systems with exceptional sound properties.
  • the design according to the invention with control elements also enables several loudspeaker systems to be coupled in a simple manner.
  • display elements such as LEDs can also be integrated into the membrane 1 or the housing 3.
  • the charging interface 7 can be implemented wirelessly.
  • the possibility of inductive charging makes the charging process easy to handle.
