Abstract
In one aspect, a sound transducer unit includes at least two magnet units having a permanent magnetic field and further includes at least two acoustic units. Each acoustic unit has a diaphragm that is deflectable along a stroke axis for generating sound waves. The sound transducer unit also includes a coil arrangement provided in association with each acoustic unit, wherein the coil arrangement is configured to be supplied electric current such that the diaphragm is deflectable along the stroke axis. The at least two magnet units and the at least two acoustic units are arranged alternatively one above the other.
Claims20
A sound transducer unit, comprising:
- at least two magnet units having a permanent magnetic field;
- at least two acoustic units arranged in the permanent magnetic field, each of the at least two acoustic units including a diaphragm that is deflectable along a stroke axis for generating sound waves;
- and
- a coil arrangement provided in association each of the at least two acoustic units, the coil arrangement configured to be supplied an electric current such that the diaphragm is deflectable along the stroke axis;
- wherein the at least two magnet units and the at least two acoustic units are arranged alternatingly one above the other,
- wherein the sound transducer unit has a front volume and a back volume,
- wherein the sound transducer unit includes a separating arrangement that separates the front volume and the back volume from one another, and
- wherein the separating arrangement and/or a housing of the sound transducer element is/are arranged such that sound from the at least two acoustic units can be combined in the front volume and/or in the back volume.
A method for operating a sound transducer unit, the sound transducer unit including at least two magnet units having a permanent magnetic field and at least two acoustic units arranged in the permanent magnetic field, each of the at least two acoustic units including a diaphragm that is deflectable along a stroke axis for generating sound waves, the sound transducer unit further including a coil arrangement provided in association each of the at least two acoustic units, the coil arrangement configured to be supplied an electric current such that the diaphragm is deflectable along the stroke axis, the at least two magnet units and the at least two acoustic units being arranged alternatingly one above the other, wherein the sound transducer unit has a front volume and a back volume, wherein the sound transducer unit includes a separating arrangement that separates the front volume and the back volume from one another, and wherein the separating arrangement and/or a housing of the sound transducer element is/are arranged such that sound from the at least two acoustic units can be combined in the front volume and/or in the back volume, the method comprising:
- operating the at least two acoustic units in synchronization with one another.
