I CLAIM:

1. An apparatus comprising:

a support structure of a wearable device;

at least one transducer coupled to the support structure, the at least one transducer being configured to generate movements in response to an audio input signal; and

at least one movement-conducting element coupled to the transducer, the movement conducting element being configured to apply the generated movements to a top portion of a user's ear,

wherein the movement-conducting element maintains contact with the top portion of the user's ear such that the generated movements are consistently conducted to the user's ear regardless of which portion of the movement-conducting element contacts the top portion of the user's ear.

2. The apparatus of claim 1, wherein the apparatus comprises a pair of artificial reality glasses.

3. The apparatus of claim 2, wherein the support structure comprises at least one temple arm, and wherein the movement-conducting element is positioned on the at least one temple arm of the artificial reality glasses.

4. The apparatus of claim 2, wherein the apparatus includes at least one transducer and at least one movement-conducting element over each of the user's ears.

5. The apparatus of claim 1, wherein the support structure, the transducer, and the conducting element each contribute to a combined weight associated with the wearable device, and

wherein the combined weight of the wearable device causes the movement-conducting element to maintain contact with the top portion of the user's ear such that the generated movements are consistently conducted to the user's ear regardless of which portion of the movement-conducting element contacts the top portion of the user's ear.

6. The apparatus of claim 1, wherein the apparatus includes at least two transducers coupled to the movement-conducting element.

7. The apparatus of claim 1, wherein the movement-conducting element includes a proximal end and a distal end, the proximal and distal ends being coupled to a counterbalancing member, and

wherein a pressure provided by the top of the user's ear on either the proximal end or the distal end of the movement conducting member causes the counterbalancing member to apply a counterforce to balance the opposite respective end of the movement-conducting element, such that the generated movements are consistently conducted to the user's ear regardless of where the movement-conducting element couples with the user's ear.

8. The apparatus of claim 1, wherein the generated movements are consistently conducted to the user's ear within a specified frequency range regardless of which portion of the movement-conducting element contacts the top portion of the user's ear.

9. The apparatus of claim 8, wherein the specified frequency range comprises about 20Hz - 20,000Hz.

10. The apparatus of claim 1, wherein the at least one transducer comprises a custom-built transducer that is optimized for specified frequencies and/or specified acoustics, and that is further impedance-matched to the user's ear.

11. The apparatus of claim 1, further comprising a dual-spring mechanism to isolate the at least one transducer from the support structure.

12. The apparatus of claim 1, wherein the movement-conducting element rests partially on the top of the user's ear, and wherein at least part of the movement-conducting element is surrounded by air, providing at least some air conduction of the input signal to the user's ear.

13. The apparatus of claim 1, further comprising a second movement-conducting element, wherein the movement-conducting element comprises a first specified length, and

wherein the second movement-conducting element comprises a second specified length that is longer than the first specified length.

14. The apparatus of claim 1, further comprising a bone-conducting transducer configured to generate additional movements in response to the audio input signal, the additional movements being optimized for bone conduction.

15. The apparatus of claim 1, wherein the apparatus includes an air conduction speaker for high-range frequencies, and further includes at least one transducer for mid-range and/or low-range frequencies.
