Abstract
An open audio device including an acoustic radiator that emits front-side acoustic radiation from its front side, and emits rear-side acoustic radiation from its rear side. A front acoustic cavity receives front-side acoustic radiation and comprises at least one front sound-emitting opening, and a rear acoustic cavity receives rear-side acoustic radiation and comprises at least one rear sound-emitting opening. The front and rear acoustic cavities each have a fundamental frequency. The fundamental frequencies are within one octave of each other.
Claims22
An open audio device, comprising:
- an acoustic radiator that emits front-side acoustic radiation from its front side, and emits rear-side acoustic radiation from its rear side;
- a front acoustic cavity that receives front-side acoustic radiation and comprises at least one front sound-emitting opening that is configured to emit front-side acoustic radiation at a front sound pressure level (SPL);
- and
- a rear acoustic cavity that receives rear-side acoustic radiation and comprises at least one rear sound-emitting opening that is configured to emit rear-side acoustic radiation at a rear SPL;
- wherein the front and rear acoustic cavities each have a fundamental frequency, and wherein the fundamental frequencies are within one octave of each other such that the front and rear SPLs are balanced, so as to reduce sound spillage.
