Description

ATΠDΪO DEVICE
The present invention relates to an audio communications device such as an earphone headset and microphone.
Existing communications headsets are relatively bulky and rely on headbands and or external ear mountings to remain in place.
The present invention seeks to provide an improved device which is lighter weight. The invention also seeks to provide a device which does not require engagement with, or support by, the rest of the head but uses the internal contours of the ear to retain the device in place.
According to the present invention there is provided an audio device comprising an earpiece member incorporating audio circuitry and a boom arm member attached thereto having a sound inlet arranged to be positioned adjacent to a wearer's mouth, wherein the earpiece member is shaped so as to be secured within the contours of a wearer's ear and to be capable of constituting the sole support for the audio device.
A microphone may be provided directly at the sound inlet or at the earpiece member in which case it is connected to the sound inlet via a sound channel extending through the boom arm. In either case a switch may be provided, externally or internally of the earphone member, for muting the microphone.
The boom arm is preferably flexible and may be connected to the earpiece member via a fixed or rotary mounting. 2
The earpiece may have an ambient sound duct extending from its exterior to a free air passage to the wearer's ear drum; the inlet of the ambient sound duct may coincide with the boom arm mounting.
A preferred embodiment of the present invention will now be described, by way of example only, with reference to the accompanying drawings, of which:
Fig. l is a view of an audio device in accordance with a first embodiment of the present invention in a position in a wearer's ear;
Fig.2 is an enlarged view of d e device of Fig 1;
Fig.3 shows an audio device in accordance with a second embodiment of the present invention with the microphone detached;
Fig.4 shows a side sectional view of the device of Fig. 3: and
Fig.5 shows a part of the device of Fig. 3
Referring to Fig. l of the drawings, an audio device 10 comprises an earphone assembly 30 mounted in a wearer's ear 20. A microphone boom 16 extends to the mouth 25 of the wearer. The earphone assembly 30 is arranged to be solely supported by ear 20 in a firm and secure manner. However, a strap for retaining the earphone assembly to the wearer' s head may be provided if desired.
Referring now to Fig.2, earphone assembly 30 comprises a hollow earmould shell 13, of plastics material, having an open face which is closed by a plate member 23, also of plastics material and carrying an earphone and other audio components. Shell 13 incorporates an earphone or sound outiet element 14 in communication with the wearer's ear drum. Plate member 23 is contoured to the shape of the earmould shell 13 and is attached thereto, preferably by adhesive.
The plate member 23 is provided with means (not shown) such as a socket, for the retention of an external communications cable. It also has a flexible boom arm 16 of sufficient length to convey sound from the mouth in the form of acoustic transmission from a sound inlet 15 to a microphone (not shown) within the earmould shell 13. The microphone and the earphone are both connected to tire external communications cable. A switch 12 is provided to electrically mute the microphone when required.
Concentrically with the mounting 26 for the boom arm 16, an ambient sound duct 11 is provided which has a free air passage to the wearer's ear drum. When the wearer wishes to listen to communications arriving through the external cable, a finger may be used to close off duct 11 to attenuate ambient sound.
The device may be used in connection witii any equipment requiring an audio communications accessory, e.g. by a radio or telephone operator or by a person requiring hands-free operation such as sports coach or umpire or a member of a bomb disposal squad.
The device can be quickly inserted and removed, and can be worn in conjunction with a wide range of headwear. in particular protective headwear. It can also be worn by people with head injuries, which would prevent them from wearing conventional headphones.
The earmould shell may be custom made to an individual ear or may be a generic shape of any configuration which will be retained in place by the internal contours of die ear alone. In both cases, the opening in the earmould shell for receiving tire plate member 23 is of standard shape and size.
Various modifications can be made to die above-described device. In particular, a microphone may be provided directly at sound inlet 15 and be connected to die rest of the earphone circuitry via wires passing inside boom arm 16: such an arrangement has me advantage of being less susceptible to ambient noise.
The ambient sound duct 11 may be provided at any convenient location in the earphone, or may be omitted.
The mounting 26 for the boom arm 16 may be fixed or it may permit rotation of die arm. The muting switch 12 may be located internally or externally of me plate member 23, or it may be omitted.
The earphone assembly may incorporate a receiver for radio communications, in which case the external cable connection may be replaced b\ an aerial.
Alternatively, die earphone components may be omitted, in which case die device 10 operates as a speak-only boom microphone.
Referring now to Figs 3 to 5, an audio device 110 in accordance witii a second embodiment comprises an earpiece 130 witii a hollow member 123 which is removably attached to an earmould 113. The cavity 124 widiin member 123 houses inter alia, an earphone 127 connected to a socket 137 to which is attached external communications wire 138. A swivel bush 126 for holding boom microphones 116 is mounted in a corresponding hole in the outside wall of member 123. Microphone 116 is also connected to die communications wire 118. The bush 126 incorporates a through free- air passage 111 for die admission of ambient sound. Sound from die inner end of passage 111 and sound from earphone 127 passes tiirough cavity 124 to an oudet duct 140 located within a projecting spigot 142.
Spigot 142 is arranged to snap fit into a metal bush 150 incorporated when casting die earmould 113. Earmould 113 is shaped to fit witiiin a user's ear and has a drilled passage 151 witii an oudet 152 from which sounds pass to a user's eardrum.
As is conventional, die member 123 may have a raised formation (not shown) spaced from the spigot 142 to limit or prevent rotation of member 123 relative to die earmould 113. Bush 150 is of die type used in hearing aids witii an interior groove accommodating a circular spring 154 for securely holding spigot 142, and an external surface 155 with serrations to enable it to be secured in die moulding material during formation of die earmould 113.
The audio device 1 10 may be manufactured and sold in the form shown in the Figures. However, widiout producing a large range of sizes and shapes of earmoulds 113, the device may not hold itself very well in a user's ear.
Accordingly, die audio device is preferably sold as a kit of parts comprising boom microphone 116, communications wire 138, hollow member 123 containing the various components, and a metal bush 150.
Having purchased me kit of parts, a proposed user visits a local hearing aid specialist and requests the making up of a customised earmould 113 to include die bush 150 and with an air passageway from the location of die bush 150 to die part of d e mould designed to fit adjacent to die wearer's ear duct. This is a simple, widely available and relatively inexpensive process. Indeed, suitable metal bushes 150 are also widely available so that die kit of parts may omit this item. The resulting product is a fully- customised audio device which fits in the ear so well diat its earpiece can constitute d e sole support.
Of course, oti er interconnection arrangements can be used for member 123 and earmould 113; for example die member may have a bush arranged to receive a spigot on he earmould. It is also possible for d e entrance to the passage 151 to be located separately from me interconnection.
Aldiough two embodiments have been described, it will be appreciated that their features and modifications may be interchanged as desired.
