Description
Background of the Invention
1. Field of the Invention
The invention relates to an attachment for a communication device, in particular a cellular telephone.
2. Description of the Related Art
Cellular telephones are often small and short. Consequently, the microphone on the cellular telephone is often next to a speaker's cheek rather than mouth if the receiver on the cellular telephone is held against the speaker's ear. The microphone only picks-up a fraction of the sound waves from the speaker's voice as a result. Additionally, cellular telephone microphones are often sensitive to compensate for the lack of proximity to the speaker's mouth, so they pick-up background noise.
The microphone on a cellular flip telephone is also typically next to a speaker's cheek rather than mouth. Such flip cellular telephones appear to have a microphone on the flip lid, but actually the microphone is on the main body of the cellular telephone. Consequently, the microphones on cellular flip telephones also only pick-up a fraction of the sound waves from the speaker's voice.
Other communication devices with microphones also frequently lack proximity to a speaker's mouth, i.e. telephones, portable telephones, and walkie-talkies. The microphones on such communication devices also only pick-up a fraction of the sound waves from the speaker's mouth.
Although attachments for communication devices are known, such attachments do not overcome the aforementioned disadvantages. For example, U.S. Pat. No. 2,245,724 discloses a voice muffler for muffling the voice of a speaker desiring to converse confidentially in the presence of others on a "hand set" type of telephone. The muffler includes a transmitter engaging member, a domed mouthpiece supporting member and a mouthpiece, which are molded of hard rubber and are substantially rigid and non-deformable. Additionally, the muffler includes a sound absorbing unit to muffle sound. In use, the mouth of the speaker is pressed against the rim of the mouthpiece to prevent escape of sound being directed to the transmitter.
Another known attachment for a communication device is disclosed in U.S. Pat. No. 2,425,061. That telephone attachment is for excluding extraneous noises from the microphone of a telephone instrument. When the user of the telephone is not talking, all sound may be excluded from the microphone of the telephone by closing a shutter. When the user is speaking, the shutter is opened so that the microphone picks-up sound.
Summary of the Invention

Description of the Preferred Embodiments
Referring now to the figures of the drawing in detail and first, particularly, to FIGS. 1 and 2 thereof, there is seen a voice reflector 1 attached to a cellular telephone 2. The voice reflector 1 reflects or redirects sounds waves of a voice into a microphone 3 on the cellular telephone 2. The reflector 1 is preferably made of a flexible material such as rubber or polyurethane so that the possessor of the cellular telephone 2 may still put the cellular telephone 2 in a pocket or purse with the voice reflector 1 attached. Alternatively, the reflector 1 is plastic such as polyethylene, PVC, etc.
FIGS. 3-7 illustrate five embodiments of the voice reflector 1 according to the invention. The voice reflector 1 is illustrated in the form of a hood or a cap 20. The inner surface of the cap 20 is a reflection region 30 which reflects sound waves into a microphone on the cellular telephone 2. The hood or cap 20 of the embodiments illustrated in FIGS. 3-7 also includes two wings 10 which attach to lateral surfaces of the cellular telephone 2.
A first embodiment of the voice reflector 1 is illustrated in FIG. 3. The voice reflector 1 connects with the cellular telephone 2 to redirect sound waves of a voice speaking into the cellular telephone 2. The cap 20 in the first embodiment integrally connects to the lateral surfaces of the cellular telephone 2. The cap 20 may be integrally connected to the cellular telephone 2 for example with glue or by heating the cap 20 and the sides of the cellular telephone 2 to fuse them together.
FIGS. 4-6 illustrate additional embodiments of the voice reflector 1 in which the voice reflector 1 includes fasteners 40 to connect the cap 20 to the cellular telephone 2. An inner surface of each wing 10 of the cap 20 has a fastener 40 in these embodiments.
The fasteners 40 are Velcro.RTM. strips in FIG. 4. Velcro.RTM. fasteners have a loop strip and a hook strip. The fasteners 40 on the inner surface of each wing 10 of the voice reflector 1 may be either a loop strip or a hook strip. In this embodiment, the cellular telephone 2 must also have a Velcro.RTM. strip attached on each longitudinal side for engaging with the Velcro.RTM. strips on the voice reflector 1. The Velcro.RTM. strips on the cellular telephone 2 are of the corresponding type to the Velcro.RTM. strips on the voice reflector 1.
Alternatively, the fasteners 40 illustrated in FIG. 4 could be adhesive tape. If the fasteners are adhesive tape, only one double-sided strip of tape is required to connect the voice reflector 1 to the cellular telephone 2.
FIG. 5 illustrates a third embodiment of the voice reflector 1. The fasteners 40 are tongues formed on the wings 10 of the cap 20 for engaging in grooves on the cellular telephone in order to connect the voice reflector 1 with the cellular telephone 2.
A fourth embodiment of the voice reflector 1 is illustrated in FIG. 6. The fasteners 40 are hinges to be engaged with bores on the cellular telephone. The hinge on one wing 10 of the cap 20 protrudes into a bore on one side of the cellular telephone, whereas the hinge on the other wing 10 of the cap 20 protrudes into a bore on the opposite side of the cellular telephone.
FIG. 7 illustrates a fifth embodiment of the voice reflector 1 according to the invention. The fastener 40 is a pocket connected to lower edges 60 of the cap 20, which are proximal to the microphone 3 on the cellular telephone 2. An end of the cellular telephone 2 proximal the microphone protrudes into the pocket of the voice reflector 1. The fastener or pocket 40 may be made from any flexible material such as padded vinyl or leather. Additionally, the pocket 40 may be elastic to permit connection with cellular telephones of various sizes. For example, the pocket could fit over a lid 4 of a cellular flip telephone, illustrated in FIG. 9, to connect the cap 20 to the cellular flip telephone.
FIG. 7a illustrates an extender 70 attached to the voice reflector 1. The preferred embodiment of the extender has an opening formed on one end. An end of the cellular telephone 2 proximal the microphone protrudes into the opening of the extender 70. Additionally, the lower edges of the cap 20 are connected to the extender 70. This embodiment ensures the voice reflector 1 is positioned proximal to a speaker's mouth even when the cellular telephone 2 is so short that the voice reflector 1 would otherwise be next to the speaker's cheek.
A sixth embodiment of the voice reflector 1 is illustrated in FIG. 8. The cap 20 has creases 50 formed therein. The creases 50 permit the cap 20 to fold up like an accordion so that the cellular telephone 2 may more easily be put in a pocket or purse with the voice reflector 1 attached.
FIG. 9 illustrates a seventh embodiment of the voice reflector 1 attached to a cellular flip telephone 2. The cellular flip telephone 2 has a microphone 3 and a lid 4.
Sound waves of a voice are directed towards an inoperable microphone 5. The voice reflector 1 of this embodiment includes a jalousie with a plurality of baffles 10 attached to the lid 4 of the cellular flip telephone 2 in order to redirect the sound waves towards the operable microphone 3. In one preferred embodiment, the baffles 10 are attached to the lid 4 with hinges so that the lid 4 can close when the baffles 10 are parallel to the lid 4. In another preferred embodiment, the baffles 10 are made of a flexible material such as rubber, polyurethane, etc. The jalousie may be connected to the lid 4, for example, with an elastic pocket as described above with respect to FIG. 7.
