Acoustic resonance is an important consideration for instrument builders, as most acoustic instruments use resonators, such as the strings and body of a violin, the length of tube in a flute, and the shape of a drum membrane. Acoustic resonance is also important for hearing.
A diagram showing the wiring of a Gibson Les Paul electric guitar. Shown are the humbucker pickups with individual tone and volume controls (T and V, respectively), 3-way pickup selector switch, tone capacitors that form a passive low-pass filter, the output jack and connections between those components. The top right shows a modification that ...
A wiring diagram for parts of an electric guitar, showing semi-pictorial representation of devices arranged in roughly the same locations they would have in the guitar. An automotive wiring diagram, showing useful information such as crimp connection locations and wire colors. These details may not be so easily found on a more schematic drawing.
A resonator guitar or resophonic guitar (often generically called a "Dobro" [1]) is an acoustic guitar that produces sound by conducting string vibrations through the bridge to one or more spun metal cones , instead of to the guitar's sounding board (top). Resonator guitars were originally designed to be louder than regular acoustic guitars ...
The exhaust pipes in automobile exhaust systems are designed as acoustic resonators that work with the muffler to reduce noise, by making sound waves "cancel each other out". [7] The "exhaust note" is an important feature for some vehicle owners, so both the original manufacturers and the after-market suppliers use the resonator to enhance the ...
The diagram shows the sound generation processes in an organ pipe and in the resonator of the Kienle Resonator System. To activate the organ pipe, the required air flow (black arrow) must be generated first in a sufficient quantity and supplied from below through the pipe foot.
The Q specifies how long resonators continue to ring after drive to them is stopped, or equivalently when viewed as filters how narrow their pass-bands are. In particular, the Q times f, or Qf product, determines the near-carrier phase noise. [41] Early MEMS resonators showed unacceptably low Qf products for reference.
Collinear transverse acoustic waves or perpendicular longitudinal waves can change the polarization. The acoustic waves induce a birefringent phase-shift, much like in a Pockels cell [dubious – discuss]. The acousto-optic tunable filter, especially the dazzler, which can generate variable pulse shapes, is based on this principle. [6]
