Omnidirectional modular siren.

摘要

An omnidirectional siren having a plurality of hollow modules supported in vertical alignment on a single, central pole. Active modules each enclose a plurality of audio transducers (i.e., compression drivers) and a horn mechanism which guides sound waves from the drivers to an outlet in the lower surface of the module. The drivers are positioned peripherally within each module so that they can be easily accessed for repair or replacement through slots in the peripheral surface of the module. <IMAGE>
