Title: TRANSDUCER APPARATUS FOR AN EDGE-BLOWN AEROPHONE AND AN EDGE-BLOWN AEROPHONE HAVING THE TRANSDUCER APPARATUS
Abstract:
With reference to Figure 2b, the present invention provides transducer apparatus (20) for an edge-blown aerophone(10), the edge-blown aerophone (10) having an aerophone embouchure hole (13). An aerophone speaker (22) delivers sound to a resonant chamber (28)of the aerophone (10) via the aerophone embouchure hole (13). An aerophone microphone (23) receives via the aerophone embouchure hole (13) sound in the resonant chamber (28).A housing (21) provides a lip plate (27)with a housing embouchure hole(29)independent and separate from the aerophone embouchure hole(13). Breath sensors(24,25,26) sense breath applied across the housing embouchure hole(29). An electronic processor (41) receives signals from the microphone (23) and the breath sensors (24, 25,26) and is connected to the speaker (23). The breath sensors (24, 25,26) provide signals indicative of breath strength. The electronic processor (41) generates an excitation signal which is delivered as an acoustic excitation signal to the resonant chamber (28) by the aerophone speaker. The electronic processor (41) uses the signals it receives to determine a desired musical note which a player of the aerophone wishes to play. The electronic processor (41) synthesizes the desired musical note and outputs the synthesized note to one of more of headphones (43), a speaker (44) external to the transducer apparatus (20), computer apparatus (45) and/or a smartphone, whereby the musical note is played audibly and/or displayed visually to the player.
