Wireless headset for karaoke inside a vehicle

Description

FIELD OF THE INVENTION

The present invention relates to a wireless headset, and more particularly to a wireless headset for karaoke inside a vehicle.

BACKGROUND OF THE INVENTION

Many people enjoy singing within a vehicle when they hear a favorite song. However, most vehicle sound system can play music from single source, either from radio, disk files, or external resources via aux input or Bluetooth connection. Therefore, there is a need for a music system inside a vehicle that allows a driver to sing, wherein such a system can receive send the driver/passenger's voice and play the voice via the vehicle speakers together with the music files being played.

Any feature or combination of features described herein are included within the scope of the present invention provided that the features included in any such combination are not mutually inconsistent as will be apparent from the context, this specification, and the knowledge of one of ordinary skill in the art. Additional advantages and aspects of the present invention are apparent in the following detailed description and claims.

SUMMARY OF THE INVENTION

The present invention features a wireless headset system for karaoke inside a vehicle. A driver or passenger wears the headset and sings with a music being played by a vehicle music player. The headset has a microphone to pick up the singing voice and send the voice to a vehicle sound system via Bluetooth connection. The vehicle sound system plays the voice via the vehicle speakers together with the music files being played.

Referring now to FIGS. 1-5, the present invention features a wireless headset system (100) for karaoke inside a vehicle (210) with a wireless headset (110). The vehicle (210) comprises a car stereo system (214), at least one speaker (216), a music player (215) and a Bluetooth receiver (212); where the music player (215) is configured to play a music file with a music signal being sent to the speaker (216) via the car stereo system (214). The music file is a compact disk (CD) track, an mp3 file, a wma file or an audio track of a video file.

The headset is a wireless single-earpiece headset (110) comprising an over-the-head headband (120) with a first end (121) and a second end (122), wherein a pad (124) is attached to the second end (122); a headphone (130) attached to the first end (122) of the headband (120); a microphone (140) attached to the first end (122) of the headband (120) via a microphone connection conduit (142); a power ON/OFF switch (152), a function switch (154), a volume up button (156) and volume down button (158) disposed on the headband (120) adjacent to the first end (121); a microprocessor (160), a battery (170) and a Bluetooth transmitter (180) disposed within the headset (110).

The microphone is configured to pick up a voice signal when the user sings. The microprocessor (160) is operatively connected to the microphone (140), the headphone (130), the battery (170), the Bluetooth transmitter (180), the power ON/OFF button (152), the function switch (154), the volume up button (156) and the volume down button (158).

The microprocessor is configured to turn off the microphone (140) when the power ON/OFF switch is turned off, wherein the microprocessor is configured and turn on the microphone (140) when the power ON/OFF switch is turned on.

The microprocessor is configured to receive the voice signal from the microphone (140), wherein when the function button is tuned ON, the microprocessor is configured to send the voice signal to the headphone (130).

When the function switch is tuned OFF, the microprocessor is configured to send the voice signal to the Bluetooth transmitter (180), wherein the Bluetooth transmitter (180) is configured to send the voice signal to the Bluetooth receiver (212); wherein the Bluetooth receiver (212) sends the voice signal to the car stereo system (214); wherein the car stereo system (214) mixes the voice signal and the music signal into a mixed signal, wherein the mixed signal is sent to the speaker (216).

In some embodiments, the headband (120) is length adjustable. In some embodiments, the microphone connection conduit (142) is length adjustable.

In some embodiments, the battery (170) resides within a battery compartment (172) disposed on the inside surface (126) of the headband adjacent to the first end (121).

In some embodiments, the headset (110) further comprises a reverb switch (159), wherein the reverb switch (159) is operatively connected to the microprocessor (160), wherein the power ON/OFF switch, function switch and the reverb switch (159) are tuned on, the microprocessor (160) is configured to receive the voice signal from the microphone (140) and add a pre-determined numbers of echoes of the voice signal, wherein the microprocessor is configured to send the voice signal and the added echoes together to the Bluetooth transmitter.

In some embodiments, the power ON/OFF switch (152), the function switch (154) and the reverb button (159) are push-button switches or micro switches. Push-button switches or micro switches are well known to one of ordinary skill in the art.
