Definitions

• This mechanical invention relates to the decrease in sound volume, therefore the decrease in the amplitude of sound, of beak instruments, such as saxophones, clarinets, etc.
• This invention is a mouthpiece which is characterized by a diaphragm (fig. 1, 1), appreciably reducing the passage of air
• the reduction in sound volume is obtained by preventing the musician from playing loudly
• the reed, generator of sound cannot vibrate noticeably, because the diaphragm (fig 1; 1) allows only a low air flow Before this diaphragm (fig 1; 1) the sound relaxes in a room sound expansion (fig 1, 2) which has a triple purpose 'firstly, the sound wave is dispersed, which reduces the amplitude of the sound II results that a sound wave at reduced amplitude passes through the diaphragm (fig 1 , 1) Second, the volume of air in this expansion chamber (fig 1, 2) serves as a pneumatic cushion.
• the air outlet channel (s) (fig. 2, 5 and 6) end in the air outlet holes (fig. 2, 9 and 10) located on the part of the spout which remains outside the mouth
• This mute differs from the amplitude and frequency modifier for wind instruments mentioned above, by the fact that its operating principle is totally different. Indeed, this invention prevents the instrumentalist from generating a high sound volume by reducing the passage of air, while the amplitude and frequency modifier decreases a sound normally generated at the beak, by absorption at a later stage. Furthermore this invention is placed in the spout, which is the cavity where the sound is formed, while the amplitude and frequency modifier elements are mounted in the jar or the barrel which, together with the body of the instrument, forms the sound amplification part of the instrument
• This invention has the advantage of allowing the musician to foil the keys of his original instrument at a less disturbing sound level. In addition, part of the volume of air in the expansion chamber makes it possible to hold a small microphone without altering the accuracy of the tones.
• This invention has the advantage that the diameter of the exhaust air channel (s) can be adjusted (pre-adjusted or adjustable) to obtain different air flows, without having to change the opening of the nozzle at the level of the 'reed.
• Figure 1 is a longitudinal sectional view of the invention, at right angles to the reed
• FIG. 2 is a view in longitudinal section of the invention along the plane AA 'shown in FIG. 1.
• Figure 1 shows the beak with its reed and its ligature (fig. 1; 4).
• the air flow is limited by the diaphragm (fig. 1, 1).
• the volume of air in the expansion chamber (fig l; 2) together with the volume of air in the compression channel (fig. 1; 3) makes it possible to generate sounds despite the small diameter of the diaphragm (fig l ; 1).
• the expansion chamber (fig. L; 2) is long and thin for guarantee a slow return of the waves, which makes it possible to easily generate the low notes.
• the sound compression channel (fig. 1; 3) directs the high waves towards the diaphragm (fig. 1; 1) to facilitate the octave jump and keep the timbre.
• the exhaust air channels are not visible in Figure 1.
• Figure 2 shows the spout on which are drawn two air exhaust channels (fig. 2; 5 and 6) independent of the sound ducts, and whose air intakes (fig. 2; 7 and 8) are located on the edges of the beak at a level which is inside the musician's mouth, and whose air outlet orifice (fig. 2; 9 and 10) are located at a level of the beak which remains outside the mouth.
• the excess air can therefore be evacuated by these two channels (fig. 2; 5 and 6).
