Abstract

Wireless headphones that allows the user to listen to a signal transmitted from a low power consumption portable FM transmitter that can be plugged into conventional portable (or in full size) receiver/amplifier or cassette, Compact Disc player. This eliminates the use of interconnecting wires. Both headphones and transmitter may be tuned to a certain number of different frequencies to allow multiple users in the same area.

Description

Title: Wireless headphones with portable FM transmitter abstract:
Wireless headphones that allows the user to listen to a signal transmitted from a low power consumption portable FM transmitter that can be plugged into conventional portable(or in full size) receiver/amplifier or cassette, Compact Disc player. This elimin:~tçs the use of interconnecting wires. Both headphones and transmitter may be tuned to a certain number of different frequencies to allow multiple users in the same area.
Specification:
This invention relates generally to the field of accessories for audio devices and to the field of cordless audio devices.
If one wished to listen to audio from a audio source without inconveniencing others then that person would use headphones or earphones and interconnecting wires, or just recently wireless infra-red headphones (Patent application number 2012487).
Headphones with cable are cumbersome because they limit the range of the user and the cord becomes a hazard. Wireless infra-red headphones solve the problem but the transmitter is big and is not portable, and infra-red does travel through the Hunan body making the position of the transmitter very important.
I have found that wireless headphones with a low-power portable FM transmitter would solve theses problems. The feature that allows the headphones and transmitter to be set at different frequencies would allow multiple users in a small area.
The low-power wireless headphone in composed of two main parts: The headset (Figure 1) and the low-power consumption portable transmitter (Figure 2).
The headset (1) is comprised of two pads and two speakers. The headset has threecontrols: a volume control switch (6), an on/off switch (7) and a frequency/channel control(15). The batteries(3) powering the headset are housed in (4) mounted on said headset. The headset also includes an whip-type antenna (5).
The second part of the system is a low-power consumption portable transmitter (Figure 2). This transmitter has a phono plug (mono or stereo depending on the choose of the maker) that plugs into the headphone jack of a conventional receiver/amplifier, cassette or Compact Disc player. An antenna transmits the audio signal. It could be a wire antenna (11) or a whip-type antenna(10). The power is provided by the use of batteries (9).
From Figure 3, you can see the output from the conventional receiver/amplifier, cassette and Compact Disc player is passed through a low-power FM transmitter that modulates the signal to a desired frequency that can be set by the user from a pre-determined selection, by turning the channel nob ( 15). The signal is then transmitted through an antenna.
The signal is then received by the antenna on the headphones (Figure 4). Then passed through a FM receiver that must be tuned to the same frequency as the transmitter.
Then the demodulated output is passed through an amplifier and then sent to the speakers.

Claims (3)

1. Wireless headphones with portable FM transmitter comprising of (a) a right and left earphone, (b) a FM receiver built into the headphones connected to the power supply and the outputs of the said receiver are connected to said earphones.
(c) a headphone antenna connected to the said FM receiver (d) a plug-in transmitter comprised of:
-an accessory antenna for said transmitter;
-a housing for said accessory transmitter;
-a phono plug connected to the transmitter and positioned in such a way to allow it to be inserted into a headphone jack of a conventional or portable receiver/amplifier, cassette/Compact Disc player, television... wherein the audio output of said a conventional or portable receiver/amplifier, cassette/Compact Disc player, television...is transmitted from said accessory transmitter to said headphone receiver so that the user can listen to the desired audio source without being tied by a cable to said audio source.
2. A FM headphone and FM transmitter according to claim 1, but they included frequency synthesizers that allow transmition and reception at several different frequencies or channels.
3. A FM headphone and FM transmitter according to claims 1 and 2 with band pass filters before the outputs to filter out noise.
