Abstract

The piezotransducer is received within a transducer housing (B), integrated in the body (A) of the wind musical instrument between the mouthpiece (F) and the sound exit opening (G) and is provided by a moisture-resistant piezo-membrane (C) with a hollow space (D) at its rear, receiving an electrical lead cable (H).

Description

Üblicherweise werden bis jetzt Kondensator- oder dynamische Mikrofone für die akustische Verstärkung von Blasinstrumenten eingesetzt. Meist werden diese außen montiert. Es gibt wenige Hersteller, die den Schall im Inneren des Instrumentes abnehmen. Dazu wird ein Tonabnehmer in eine entsprechende Bohrung zwischen Mundstück und Klappen bzw. Ventilen eingesetzt. Jedoch werden bisher in jedem uns bekannten Fall dafür Kondensator- oder dynamische Mikrofone verwendet. Diese haben jedoch folgende Nachteile:Usually are condenser or dynamic microphones for acoustic reinforcement used by wind instruments. Most of these are mounted outside. There are only a few manufacturers that absorb the sound inside the instrument. To do this, insert a pickup into a corresponding hole mouthpiece and flaps or valves are used. However, so far in everyone known case for us Condenser or dynamic microphones are used. However, these have the following disadvantages:

  • – Sie sind nur für relativ geringe Schalldrücke geeignet und übersteuern schnell.- She are only for relatively low sound pressure suitable and override fast.
  • – Mikrofone sind empfindlich gegenüber Feuchtigkeit.- microphones are sensitive to Humidity.
  • – Konstruktionsbedingt ergibt sich oft ein schlechter Frequenzgang.- Due to construction there is often a poor frequency response.

Die Neuheit bei meiner Entwicklung ist der Einsatz einer Piezoscheibe zur direkten Schallabnahme. Piezos werden bisher üblicherweise als Signalgeber oder Körperschall-Tonabnehmer eingesetzt. Bei unserem Tonabnehmer nimmt die Piezoscheibe die Luftschwingung im Inneren des Blaasinstrumentes direkt auf. (Differenzdruck zwischen innen und außen.) Dazu wird ebenfalls eine Bohrung zwischen Mundstück und Klappen bzw. Ventilen gesetzt, in die der neuartige Piezo-Tonabnehmer bündig eingesetzt wird. Die Vorteile dieses Piezo-Tonabnehmers sind:The novelty in my development is the use of a piezo disk for direct sound absorption. piezos have been common so far used as a signal generator or structure-borne sound pickup. With our pickup, the piezo disc absorbs the air vibration inside the Blaasinstrument directly. (Differential pressure between inside and outside.) There is also a hole between the mouthpiece and the flaps or valves set, in which the new piezo cartridge is inserted flush becomes. The advantages of this piezo pickup are:

  • – nicht übersteuerbar und somit für höchste Schalldrücke optimal geeignet.- cannot be overridden and therefore for optimal sound pressure suitable.
  • – optimaler Frequenzgang- more optimal frequency response
  • – völlig resistent gegenüber Feuchtigkeit - completely resistant across from humidity
  • – günstig in der Herstellung- cheap in the production
  • – sehr robust- very robust
  • – durch bündigen Einbau (kein zusätzliches Volumen) keine Veränderung der Klangeigenschaften des Instruments- by flush Installation (no additional Volume) no change the sound characteristics of the instrument
  • – konstruktionsbedingte geringe Körperschallübertragung- design-related low structure-borne noise transmission
