Device For Creating A Sound Source

摘要

Described is a device for creating a sound source comprising integrated measuring means (50) for measuring a property representative of the strength of the sound source, the device comprising a sound generator (40a, 40b) for generating sound within an annular space defined around a central axis, the device comprising a pair of guiding surfaces (113, 123) for guiding sound away from the annular space in opposite directions along the central axis. With sound being guided as described, sound in addition being allowed to propagate outside the device in a radial direction with respect to the central axis, a high degree of omnidirectionality of the created sound source is attained.

1. A device for creating a sound source comprising:
integrated measuring means for measuring a property representative of the strength of the sound a housing having a sound emission area comprising at least one emission opening for emitting a sound wave; and at least one sound generator for generating a sound wave, arranged in the housing so as for a generated sound wave to radiate from the sound emission area; wherein the housing has a longitudinal axis and a continuous circumference within a plane perpendicular to the longitudinal axis, the housing comprising a pair of housing portions located on opposite sides of the sound emission area, the housing portions each having a cylindrical outer surface extending away from the sound emission area along the longitudinal axis, the sound emission area extending along the continuous circumference.
