40 results about "In-ear monitor" patented technology

A multi-driver in-ear monitor for use with either a recorded or a live audio source is provided. If a pair of drivers is used, each driver has an individual sound delivery tube. If three drivers are used, the outputs from two of the drivers are merged into a single sound delivery tube while the output from the third driver is maintained in a separate, discrete sound tube. The sound delivery tubes remain separate throughout the end portion of the earpiece. The earpiece tip is configured to be fitted with any of a variety of sleeves (e.g., foam sleeves, flanged sleeves, etc.), thus allowing the in-ear monitor to be easily tailored to comfortably fit within any of a variety of ear canals. Due to the size constraints of such an earpiece, the sound delivery tubes include a transition region. Acoustic filters (i.e., dampers) can be interposed between one or both driver outputs and the earpiece output.

A system and method that reduces the perceptual effect resulting from ear occlusion include an electro-acoustic feedback network that produces phase canceling sounds in the ear, where a receiver and a microphone are located. A control mechanism controls the response of the feedback network to minimize distortion in the ear while maintaining a desired frequency response for external signals. Devices producing the external signal include hearing aids, personal sound devices, in ear monitors, communications headsets and hearing protectors. The integration of the above with these devices improves a user's perception of their own voice.

An in-ear monitor for use with either a recorded or a live audio source is provided. The disclosed in-ear monitor combines a single diaphragm driver and a single armature driver within a single earpiece, thereby taking advantage of the capabilities of each type of driver. Preferably, the diaphragm is used to reproduce the lower frequencies while the higher frequencies are accurately reproduced by the armature driver. Such a hybrid design offers improved fidelity across the desired frequency spectrum and does so at a reduced cost in comparison to multiple armature designs. In addition to the two drivers, the disclosed in-ear monitor includes means for splitting the incoming signal into separate inputs for each driver. Typically this function is performed by a passive crossover circuit although an active crossover circuit can also be used. In at least one embodiment, acoustic dampers are interposed between one or both driver outputs and the eartip.

A multi-driver, in-ear monitor is provided that is coupleable to an external audio source, for example via a source input cable or a wireless receiver. A circuit, for example comprising a passive or active crossover circuit, receives the electrical signal from the external audio source and provides separate input signals to the drivers contained within the in-ear monitor. A plurality of sound delivery tubes acoustically couple the audio output from each of the drivers to the acoustic output surface of the in-ear monitor. The in-ear monitor may be configured as a custom fit IEM or configured to accept a removable eartip. The plurality of sound delivery tubes may be comprised of a pair of concentric tubes; a pair of concentric tubes and a discrete tube; or three concentric tubes.

A system and method are provided for controlling the own-voice experience of a user who talks while an earpiece is mounted to occlude an ear of the user. A vibration sensor is engaged with the user's head to sense vibrations formed by the user speaking and conducted by the user's head to the vibration sensor. A signal generator operates a speaker element, which is integrated with the earpiece, to generate sound waves in the ear canal of the user, based on the output signal of the vibration sensor. The signal generator generates the sound waves to at least partially cancel other sound waves that are generated by at least part of said vibrations entering the ear canal from surrounding bone and / or tissue. The system and method counteracts the occlusion effect and are applicable in connection with in-ear headsets, earphones, in-ear headphones, in-ear monitors, circumaural headphones, hearing aids, earplugs and earmuffs.

A headset with an active crossover network is provided. The headset is coupleable to a first audio source using a wired connection and to a second audio source using a wireless connection. A controller is used to determine whether the first, or second, audio source is coupled to the active crossover network which, utilizing either analog or digital filtering, divides each channel of the incoming audio signal into multiple frequency regions sufficient for the number of drivers contained within the in-ear monitors of the headset. The output from the network's filters is amplified using either single channel or multi-channel amplifies. Preferably, gain control circuitry is used to control the gain of the amplifier(s) and thus the volume produced by the drivers. More preferably, the gain of the gain control circuitry is adjustable. The headset includes a power source that is coupled to the amplifier(s) and, if necessary, the network's filters. The power source can be included within some portion of the headset or included within the wireless interface. Alternately, an external power source can be used, for example one associated with the audio source.

A custom-fit in-ear-monitor (IEM) is provided that utilizes a plurality of drivers and a single piece driver module that significantly simplifies fabrication while insuring that the completed IEM achieves the desired acoustic performance. The driver module, which is fit within a custom-fit ear mold shell, includes a plurality of driver ports to which the drivers are coupled. The driver module also includes an acoustic output member that includes one or more sound bores that acoustically couple the acoustic output surface of the custom-fit ear mold shell to the plurality of driver ports via a plurality of sound ducts within the driver module.

A wireless audio transmission system which has at least one wireless transmitter for the wireless transmission of a detected audio signal as a first audio signal by way of a first wireless transmission path. The wireless audio transmission system further has at least one in-ear monitor unit for directly receiving the first audio signal and for receiving a second audio signal. The first and second audio signals are mixed in the in-ear monitor unit and output as an output signal. The wireless audio transmission system has a mixing desk for mixing the first audio signal and further received audio signals to give an output signal which can be output to the public or recorded.
