Abstract
The invention relates to audio transducer technology, including audio tuning systems to be utilised in personal audio devices, such as headphone, earphones, mobile phones and the like. The audio tuning system optimises the frequency response of the personal audio device by using Diffuse Field curve characteristics. The audio transducers of the personal audio device incorporate low resonance designs, including low resonance transducer and diaphragm suspensions to further optimise the sound quality of the device. The invention also relates to an audio transducer diaphragm construction that includes a three-dimensional lattice which may be utilised in any audio transducer application.

-173. (canceled)
An audio system comprising:
- a personal audio device having:
- at least one output audio channel comprising:
- a housing;
- and
- at least one electro-acoustic transducer associated with the housing that is operable to convert an input audio signal into sound;
- and
- an audio tuning system operatively coupled to the one or more output audio channels, comprising:
- a bass control module configured to adaptively adjust lower cut-off frequency of a frequency response of the audio system based on one or more predetermined characteristics associated with the respective output audio channel(s) of the personal audio device;
- and
- an equaliser configured to adjust the frequency response of the audio system such that the frequency response increases a voltage passed into each output channel at frequencies below approximately 200 Hz, relative to the voltage over a frequency range of approximately 200 Hz to 400 Hz.
An audio system as claimed in claim 1 wherein the audio tuning system is on-board the personal audio device and located within the housing of at least one output audio channel.
