Abstract
A receiver tube for connecting a receiver to a hearing aid instrument and a hearing aid instrument with a receiver tube, include a connection which ensures good acoustic stability and low feedback tendencies, can be produced in an uncomplicated manner and has high impact and shock strength. The receiver tube includes a receiver connector constructed as a cup at least partly holding a receiver when connected together. The receiver connector includes a form-locking mechanism for a receiver and a flexible element for locking the receiver. The form-locking connection simplifies installation of the receiver during production or replacement by requiring neither application of a force, as when pretensioning or expanding force-locking connections, nor establishment of an adhesive connection. The locking mechanism can be opened/closed by the flexible element. The cup-shape of the receiver connector contributes to increased rigidity and reliability of the form-locking connection to the receiver and an acoustic shield.
