Definitions
- the invention relates to an electroacoustic transducer which in turn either as Sound generator or acts as a sound receiver and in particular the assembly of such acoustic transducer in one device, for example a mobile phone, headphones, console a computer screen etc.
- Main friction an air path, the volume under the membrane, that's the one between of the membrane and the bottom-lying component initially enclosed Volume that connects to the ambient volume behind the transducer.
- Main friction an air path
- the volume under the membrane that's the one between of the membrane and the bottom-lying component initially enclosed Volume that connects to the ambient volume behind the transducer.
- the aim of the invention is to find a solution that enables the main friction of an electroacoustic transducer only when installed in a device to the respective Adjust necessities, so that all electro-acoustic transducers are installed Series are identical, which means that production, warehousing and repair are essential is simplified.
- these goals are achieved in that in the floor and / or wall area of the electroacoustic transducer is provided at least one and that projections are provided in the device to be equipped with this converter, which at Assembly of the converter the passage between the membrane volume and the back volume define and thus form the desired main friction.
- This solution according to the invention actually allows one and the same electroacoustic Install transducers in different devices because the devices are arranged on the device side Projections the air passages provided in the electroacoustic transducer between the Reduce the membrane volume and the back volume or close it at all so that the desired main friction is created.
- electroacoustic Converter mounted on the parts 2 'and 2 "of a device, not shown.
- the converter 1 consists essentially of a housing 3 and, in the illustrated electroacoustic transducer, a magnet system 4. Between the yoke edges of the Magnet system 4 is formed a circular gap in which a coil in the axial Can swing direction, which is attached to a membrane 6, mostly glued is.
- the membrane volume lies between the magnet system 4 and the membrane 6 5, which changes with the movement of the membrane.
- the characteristic of the electroacoustic transducer now essentially depends on how this membrane volume 5 is connected to the back volume 7.
- the embodiment is the connection between the membrane volume 5 and Back volume 7 from a substantially annular gap 8 'and a central opening 8 ".
- the converter is received by the device-side parts 2 'and 2" these connections between membrane volume and back volume through projections 9 ', or a stamp-like projection 9 ", reduced to the desired extent.
- the central part 2 " a specially manufactured part, which at or just before the installation of the converter 1 in the device attached to the converter, for example glued the corresponding mounting location in the device can of course also be designed in this way be that the part 2 "with the part 2 'by webs or the like. In connection and so part of a wall or an intermediate wall of the device in which the converter 1 is to be installed is represents.
- the device sections are the projections 9 'and 9 ", shown as separate components, but of course this is not necessary, these projections can be integral parts of the mostly made of plastic Housing of the device in which the converter is inserted.
- the converter won't mounted directly on the housing, so of course any other device part can do this wear, or in this case own components are actually used.
