Abstract
A vehicle and an adjustable sound distribution system that includes an engine operable to produce a pulsation and a sound assembly coupled to the engine. The sound assembly is disposed upstream from the engine. The sound assembly is configured to generate sound from the pulsation. The sound assembly includes a housing defining a cavity configured to resonate the sound that exits the sound assembly. The sound assembly also includes a first member movable to change a frequency of the sound that exits the sound assembly.
Claims20
An adjustable sound distribution system comprising:
- an engine operable to produce a pulsation;
- and
- a sound assembly coupled to the engine and disposed upstream from the engine, and wherein the sound assembly is configured to generate sound from the pulsation;
- the sound assembly comprising:
- a housing defining a cavity configured to resonate the sound that exits the sound assembly;
- a first member movable to change a frequency of the sound that exits the sound assembly;
- wherein the first member is at least partially disposed in the cavity which creates an open space inside the housing, and wherein the first member is movable relative to the housing to change a size of the open space inside the cavity which changes the frequency of the sound that exits the cavity;
- and
- wherein the sound assembly includes a diaphragm attached to the first member and contained inside the cavity, and wherein movement of the first member changes a position of the diaphragm inside the cavity which changes the size of the open space inside the cavity.
An adjustable sound distribution system comprising:
- an engine operable to produce a pulsation;
- and
- a sound assembly coupled to the engine and disposed upstream from the engine, and wherein the sound assembly is configured to generate sound from the pulsation;
- the sound assembly comprising:
- a housing defining a cavity configured to resonate the sound that exits the sound assembly;
- a first member movable to change a frequency of the sound that exits the sound assembly;
- a diaphragm;
- wherein:
- the first member includes a first end and a second end spaced from each other, with the diaphragm attached to the first end;
- the housing includes a first end and a second end spaced from each other, with the cavity extending through the first end of the housing, and spaced from the second end of the housing;
- the sound assembly includes a first tube attached to the second end of the first member and a second tube attached to the second end of the housing;
- and
- the first tube is coupled to the engine and configured to guide the pulsation from the engine into the first member, and the second tube is configured to guide the sound from the cavity out of the sound assembly.
An adjustable sound distribution system comprising:
- an engine operable to produce a pulsation;
- and
- a sound assembly coupled to the engine and disposed upstream from the engine, and wherein the sound assembly is configured to generate sound from the pulsation;
- the sound assembly comprising:
- a housing defining a cavity configured to resonate the sound that exits the sound assembly;
- a first member movable to change a frequency of the sound that exits the sound assembly;
- wherein:
- the housing is defined as a plurality of housings each defining one cavity;
- the sound assembly includes a plurality of diaphragms, with one of the diaphragms disposed in the cavity of the respective housings to set different frequencies of the sound that resonates in each cavity;
- and
- the first member is movable to select the desired frequency of the sound that exits the cavity of the respective housings.
