Abstract
A device, including an electromagnetic transducer including a bobbin having a space therein, a connection apparatus in fixed relationship to the bobbin configured to transfer vibrational energy directly or indirectly at least one of to or from the electromagnetic transducer, and a passage from the space to the connection apparatus.
Claims41
A device, comprising:
- an electromagnetic transducer including a bobbin having a space therein;
- a connection apparatus in fixed relationship to the bobbin configured to transfer vibrational energy directly or indirectly, at least one of to or from the electromagnetic transducer;
- and
- a passage from the space to the connection apparatus.
1 more element
A method, comprising:
- transmitting a force through a space extending through an electromagnetic transducer, thereby at least one of fixing or unfixing a component to or from, respectively, the electromagnetic transducer.
A device, comprising:
- an electromagnetic transducer in vibrational communication with a fixation component, wherein the electromagnetic transducer is locationally fixed to the fixation component via a mechanical connection extending through the electromagnetic transducer.
A method of transducing vibration, comprising:
- transmitting vibration to or from an electromagnetic transducer subcutaneously implanted in a recipient and in vibrational communication with a single point fixation system securing the electromagnetic transducer to bone of the recipient at a single point.
A device, comprising:
- an electromagnetic transducer including a bobbin through which a dynamic magnetic flux flows, wherein at least a portion of the bobbin forms a magnetic core having a wall thickness of about ten times or less of a depth of penetration of the dynamic magnetic flux at that location.
