Problems solved by technology

However, a further miniaturization of the above-mentioned known device and the above-mentioned acoustic-electric transducer causes problems because of the mating contact element formed by the terminal contact element with a bent contact spring and the conductive track area on the printed circuit board A normal conductive connection can only be established if the structure of the housing and the structure of the printed circuit board lie within relatively narrow tolerance limits, since the contact element with a bent terminal can only compensate the tolerances in the above-mentioned structure to a limited extent
It should also be noted that the above-mentioned terminal contact element composed of a curved contact spring provided by the patent document WO98 / 38832 A1 can only be miniaturized to a limited extent, and thus cannot be compared with existing converters. Further miniaturized converters are used in

Abstract

In an apparatus (1) having an electroacoustic transducer (14) and having a printed circuit board (51) the electroacoustic transducer (14) has two terminal contact elements (36, 37) and the printed circuit board (51) has two mating contact elements (52, 53), which terminal contact elements (36, 37) have two terminal contact portions (38, 39) which are oriented parallel to the transducer axis (34) of the transducer (14) and which mating contact elements (52, 53) have two mating contact portions (56, 57) which are oriented parallel to the transducer axis (34), the terminal contact portions (38, 39) and the mating contact portions (56, 57) being held pairwise against each other in a direction transverse to the transducer axis (34) and thus forming at least parts of a retainer (72) with the aid of which the transducer (14) is secured to the printed circuit board (51).

Description

technical field [0001] The invention relates to a device having a housing and an acoustic-electric transducer accommodated in the housing. [0002] The invention also relates to an acoustic-electric transducer. Background technique [0003] Devices having a housing and an acoustic-electric transducer housed in the housing and the acoustic-electric transducer have been widely used and are known. For this known structure, reference can be made to patent document WO98 / 38832 A1. According to the patent document WO 98 / 38832 A1, the known construction of such an acoustic-electric transducer can be fastened to the housing of a known device by means of a fastening device. The printed circuit board is then also fastened to the housing or connected to a stationary part of the housing by means of other fastening means. The terminal contact element is formed with a bent contact spring. The mating contact elements are formed by areas of conductive traces on the printed circuit board....
