This application is a continuation of application Ser. No. 892,641, filed Aug. 4, 1986, now abandoned.
BACKGROUND OF THE INVENTION1. Field of the invention
The present invention relates to audio communication and more particularly to a sound intake control device and adjustable supports therefor.
Radios, tape players and other audio equipment have been miniaturized to such an extent that they may be conveniently carried on the person of a user, such as in a pocket or other portion of the wearer's clothing or accessories. Many diverse audio sources are now in use.
A need in terms of safety, further choice in listening capability, and the intake and/or blocking of external sounds has arisen. This device has been created to answer the needs of pilots, communications personnel, music lovers, airport linemen or anyone with the need to hear more than one audio source simultaneously and/or in regulated quantities or levels. This invention is designed to accurately achieve multiple source sound (sound on sound), single source sound or no sound.
Presently and as technological and social change occur the demand for safety, utility and convenience are major considerations. A device which provides a means for greater discrimination of aural sources will aid many people who desire to listen, communicate and deal with sound more effectively.
This invention is also directed toward a means of providing high quality sound reproduction with the versatility to be utilized as a headset, earphones and/or hearing aid or earplugs. The device can be worn in combination with, or as a means to secure spectacles or headgear of the wearer. The design places the device where it can be utilized on a regular basis.
This invention is directed toward a manner of mounting miniature speakers or earphones to enhance their utility, versatility and minimize any inconvenience or discomfort as a result of the supporting components.
2. Description of the prior art
At present audio headsets and earphones are limited to a single position; existing headsets and earphones enclose the ear, are pressed adjacent to the ear, are placed in the outer ear, or, are positioned inside the auditory canal.
Prior art, due to this single position limitation, has the inherent effect of masking outside sounds with sound produced by the earphones. With respect to safety, the wearer is hindered in his ability to hear surrounding sounds such as instructions, warnings, automobiles, sirens, conversations etc.
The most widely used, present design audio headset is awkward to wear and cumbersome to carry. Cord entanglement problems occur regularly and the resulting entanglement can cause short circuiting of speaker or microphone leads, as well as incur the bother and loss of time spent untangling headset wires.
Additional entanglement problems arise when the now common "leash" (a retainer cord used to suspend the glasses around the wearer's neck when not in use) is worn simultaneously with the prior art headset.
Another difficulty involves the wearing of a hat, visor or helmet and a prior art headset simultaneously. Since the majority of headsets in use today consist of a band, which transversely spans the head, a hat, helmet or visor does not fit the wearer's head properly when worn in combination with the headset. At present the small in ear-type headsets circumvent this problem however sound quality is sacrificed due to the extra small size of the speakers and they are limited to a single position.
Further shortcomings of prior art include the lack of single hand placement. Both hands are needed to place the headset or earphones in listening position.
Other prior art devices disclose speakers or earphones used as hearing aids for the hard of hearing some of which were supported by spectacles or constructed as a part thereof, such as disclosed by Pat. No. 2,874,230 in which the terminal end of the respective sidepiece supports a speaker.
The present invention is distinctive over prior art devices by adjustably supporting a pair of miniature speakers on headgear or spectacle sidepieces which can be positioned in the ear, adjacent the ear or in varying distances from the ear as desired. The inherent design serves multiple functions and places the sound in the control device where it can be safely heard, worn, transported and utilized more effectively.
SUMMARY OF THE INVENTIONA pair of miniature speakers, each connected with one end of an audio lead are provided with members connecting the respective speaker to means on the head of the user, such as a respective spectacle sidepiece or headgear having a band horizontally surrounding the head of the user or the user's hair which supports each speaker in depending relation for vertical adjustment of the speaker toward and away from the sidepiece or headgear and for horizontal movement longitudinally of the sidepiece or headgear. The other end of the respective audio lead is joined to a plug removably received by an audio jack in equipment supplying an audio signal. An audio lead gripping member surrounds the two leads intermediate their ends which serves to maintain the two leads in single cord fashion and by sliding movement longitudinally of the leads acts as a retainer or chin strap for maintaining the speakers and the glasses sidepiece adjacent the user's ears when the leads are located in front of the user's neck, or alternatively as a support or leash for hanging the speakers and spectacles from the user's neck when the leads and plug end extend rearwardly of the user's neck.
Horizontal movement of the speakers longitudinally of the sidepieces or headgear allows the user to position the speakers relative to the ear as desired. If very little external sound is desired to be heard, the user locates the speakers in or adjacent the ears. If more external sound is desired, the speakers are moved forwardly and away from the ears as necessary and the volume adjusted to attain the desired ratio of speaker and external sound mixing (sound on sound).
Vertical movement of the speakers relative to the glasses allows accurate positioning with respect to the ear for different individuals and different sidepieces. Additionally, the vertical movement can be utilized to perform the external sound versus speaker sound (sound on sound) adjustment as primarily achieved by the horizontal positioning.
The attachment to the spectacles or headgear allows the device to be placed near the ears safely and easily with only one hand because the spectacles or headgear are designed for single hand placement. This eliminates the cord entanglement aggravation caused when combining a headset with a spectacle leash, by combining both devices into one apparatus.
The principal objects of this invention are to provide a personal user supported audio unit comprising a relatively inexpensive assembly of audio earphones easily connected with and supported by headgear or the sidepieces of any conventional pair of spectacles and which may be adjusted relative to the headgear or sidepiece either laterally longitudinally or vertically to position the ear-phones in a comfortable position adjacent or within the ear for maximum audio and which can enable the user to hear and identify sounds from sources other than the audio set connected with the earphones.

DESCRIPTION OF THE PREFERRED EMBODIMENTSLike characters of reference designate like parts in those figures of the drawings in which they occur.
In the drawings:
Thereference numeral 10 indicates the unit as a whole. Thedevice 10 comprises a pair of conventional, commerciallyavailable miniature speakers 12 and 14 operatively connected with one end of audio leads 16 and 111, respectively, with the other end of the leads connected with aplug 20 in a conventional manner. Each of the speakers may include acover 22 through which audio sounds are transmitted and an opposite or rearward substantiallycylindrical portion 24, having avent 25, which receives and is connected with the above named one end portion of the respective audio lead. The respectivecylindrical portion 24 is transversely apertured, as at 26, for frictionally receiving, in sliding relation, a portion of the respective audio lead adjacent its connected end to form an audio lead closedloop portion 28 which may be increased or reduced in size to allow thespeakers 12 or 14 to be moved vertically for adjustment purposes.
Aflexible connector 30 is connected with eachspeaker loop 28. Theflexible connectors 30 are preferably endless bands with juxtaposed portions of its wall surrounded and gripped in sliding relation by atension adjuster 32 to define substantially figure eight configuration.
Theconnectors 30 may be formed by an endless band or may be a strap-like length of flexible plastic material doubled back upon itself from both of its ends and secured together. A tension adjuster 32, transversely surrounding the connector band, is formed by a helically twisted length of wire, or the like, and defines oppositely disposed closedloops 34 and 36 at respective ends of the flexible connector. Theloop 34 is engaged with thespeaker loop 28 in chain link fashion and theother loop 36 of the flexible connector transversely surrounds a respective one of a pair ofspectacle sidepieces 38 intermediate its ends. Theloop 36 allows horizontal movement of the speakers longitudinally of the respective sidepiece.
A tension adjuster member 32' also surrounds the audio leads 16 and 18 intermediate their ends for the purpose presently explained. Arheostat 50 is interposed in theleads 16 and 18 between the tension adjuster 32' and theplug 20 as a volume control. An alligator-type clip or clamp 52 is attached to the leads between thevolume control 50 and the tension adjuster 32' for supporting the volume control in a convenient location as by attaching the clamp 82 to a portion of the user'sclothing 54.
Referring also to FIGS. 2 and 3, thereference numerals 40 and 41 indicate a pair of spring clips or clamps which may be used in place of theconnectors 30. This is accomplished by permanent attachment of the clamp to the speaker cord or manually opening the respective spring clamp so that thespeaker cord loop 28 is received between thegripping end portion 42 of the clamp and its spring closed hingedconnection 44 so that therespective speaker 12 or 14 is then supported in depending relation from the respective clamp. Theclamp gripping end 42 is then disposed on opposing sides of therespective spectacle sidepiece 38 at a selected location intermediate its length.
In the event the user of the device does not wear spectacles, theclamps 40 permit attachment to other headgear, such as the sweatband of a hat, not shown, or the band of a visor, as indicated at 46 (FIG. 3). Therespective clamp 40 and 41 is positioned as shown with itsgripping end edge 42 gripping opposing sides of the depending edge portion of thevisor band 48.
Referring more particularly to FIG. 4other clamps 60, only one being shown, similarly gripping thespectacle earpieces 38, supportsimilar speakers 62 in cantilever fashion by arm means 64. Apad 63 surrounds the major portion of the speaker. In the example shown the arm means 64 comprises a forward bar 66 rigidly attached at one end to theclamp 60 opposite its gripping end portion 68 and longitudinally slidably attached at its other end portion to the forward end portion of arearward arm 70 having its opposite or rearward end rigidly secured to thespeaker 62. This permits vertical adjustment of the speaker relative to thesidepiece 38 and the user's ear, not shown, by the angular position of theclamp 60 relative to the longitudinal ads of the sidepiece. Forward and rearward adjustment of thespeaker 62 relative to the sidepiece and the user's ear is achieved primarily by the sliding movement of thearm 70 relative to the bar 66 and secondly by the position of theclamp 60 longitudinally of the sidepiece. It seems obvious that thearm 70 may serve as a gooseneck having a ball at its rearward end cooperatively received by a socket formed in the housing supporting the speaker components to impart substantially all the advantages of ball and socket movement of thespeaker 62 relative to the user's ear, if desired.
OPERATIONIn use theflexible connectors 30 have their free loop ends 36 transversely surrounding the respective spectacle sidepiece. With the spectacles in wearing position, the speakers are adjusted by moving theflexible connectors 30 longitudinally of the respective sidepiece so that the speakers are positioned relative to the user's ear in a desired position in accordance with other parameters which may or may not be limiting the user's attention. For example, the speakers may be positioned so that a desired audio program may be heard and yet other sounds may also be received, such as automobiles, warnings, instructions or the conversations of others. By moving theadjuster 32 toward the respective sidepiece the size of theloop 36 is reduced to grip the sidepiece so the speakers are frictionally maintained adjacent or in the user's audio canal, as desired. The speakers may be positioned independently of each other to further enhance listening capabilities.
The strap-like configuration of theconnectors 30, in combination with a small size for theloop 34, prevents angular rotation of either speaker about a vertical axis through therespective connector 30. The coefficient of sliding friction between theconnector loop 36 and the surface of thesidepiece 38 prevents movement of one component relative to the other except as manually induced. The speakers are easily adjusted vertically relative to the sidepieces or the user's ears by increasing or decreasing the size of thelead loop 28. Further, if the user desires the speakers to be in close proximity to the ear the lead adjuster 32' may be moved longitudinally of the leads until disposed in underlying relation with respect to the user's chin to place a slight tension on theleads 16 and 18 and draw the speakers inwardly toward each other.
Alternatively, the leads may be positioned rearwardly of the user's head and the adjuster 32' disposed adjacent the back of the head to maintain the speakers adjacent the ears and to maintain the spectacles in place on the face of the user. In this position thespeaker assembly 10 may also be employed to support the spectacles in a position hanging from the user's neck.
It seems obvious that the spring clamps 40 and 41 may be connected with thelead loops 28, as described hereinabove, for use with the headgear as desired.
Obviously the invention is susceptible to changes or alterations without defeating its practicability. Therefore, I do not wish to be confined to the preferred embodiment shown in the drawings and described herein.
