AN APPARATUS FOR USE IN THE ADJUSTMENT OF THE SECONDARY ADJUSTMENT MEANS OF A HEARING AID

摘要

An apparatus intended for use in the adjustment of the secondary adjustment means (18) of a hearing aid (10) consists of an adaptor (20) which can be so placed on the hearing aid that the adjustment means of the aid are coupled to corresponding moving means (26) on the adaptor. These moving means are in turn coupled to their respective activation means (28) on a control desk (19) through their respective wires (27) in a bowden cable (21), enabling the secondary adjustment means of the hearing aid to be adjusted with the aid in the position of use on the patient by manipulation of the activation means of the control desk. Transformation mechanisms may be inserted between these and the cable wires so that the desk and its buttons as well as the extent of their movements can be given a suitable size allowing convenient manipulation.
