Description

A WIRELESS ENHANCED SOUND SYSTEM AND RETROFIT CONTROL MODULE Related Applications [001a] This application is a divisional application of international patent application no. PCT/AU2016/000124 filed on 8 April 2016, and claims priority to Australian provisional patent application no. 2015901248 filed on 8 April 2015; This application is also related to Australian patent application no. 2017100398 filed on 7 April 2017. The entire contents of each of these applications is incorporated herein by reference.

Field of the Invention [001] The present invention relates to a wireless enhanced sound system and in particular to a wireless enhanced sound system in a vehicle.

Background of the Invention [003] A vehicle sound system is customarily included in the original specifications of the vehicle when purchased. The components are hard wired and therefore limited to the original specification. However the quality and effect of the sound system will then match the cost of the vehicle. If it is an expensive luxury car then there is a great sound system. But if the vehicle is anything other than an expensive luxury car the sound system is often not to the standard required.

[004] With the hard wiring of systems it is necessary to fully remove the original sound system or to include a second sound system mounted in a secondary position. These options are expensive and often aesthetically downgrades the look of the interior of the vehicle.

[005] A further aspect in the sound system is the new choice of storage of music for play on a sound system. Generally most music is now downloaded onto hard drives in mobile phones or iPod or audio hard drives in MP3 or MP4 format or the like. Therefore the source of the audio for sound system is separate and needs to be plugged into the auxiliary port of the vehicle sound system. This is irritating to find the right cords. Also the mobile phone is tethered to the spot and therefore readily forgotten when leaving the vehicle or otherwise inconvenient when in use in legally allowable circumstances requiring disconnection and reconnection.

[006] The present invention seeks to provide a wireless enhanced sound system, which will overcome or substantially ameliorate at least one or more of the deficiencies of the prior art, or to at least provide an alternative.

[0047] However the enhanced sound system includes a control module 31 which controls transmission from the audio input 21, 22 to an amplifier system having a first speaker system; and a separate enhancing amplifier speaker system; wherein the control module includes: [0048] The input means of the control module 31 is for receiving an audio input wirelessly from an audio source 21,22; and an output means having a first transmitter for wirelessly connecting to the amplifier 41 of the first speaker system and a second transmitter able to wirelessly connect to the separate enhancing amplifier speaker system having amplifier 32 and speaker 51 wherein the wireless enhanced system coherently delivers audio from the audio source to the first transmitter and the second transmitter for providing enhanced amplification of the audio source.

[0049] The audio source is a portable audio input such as a USB or SD card 22 or a mobile phone 21 or iPod or other portable audio input. Particularly the audio source is a portable audio input such as a mobile phone 21 that wirelessly transmits via Bluetooth to the control module 31, or wirelessly transmits via Wi-Fi to the control module, or wirelessly transmits via FM radio transmission to the control module.

[0050] The amplifier system has the first speaker system 41, 42 wirelessly receiving audio signal from the first transmitter by Bluetooth, or wirelessly receives audio signal from the first transmitter by Wi-Fi or wirelessly receives audio signal from the first transmitter by FM radio transmission.

[0051] The wireless enhanced sound system therefore in Figure 1 includes the amplifier system having the first speaker system being a vehicle audio system and including a receiver 41 for receiving audio signal transmitted wirelessly from the first transmitter 33. The amplifier system has a first speaker system receiving the full audio signal while the second amplifier 32 receives audio signal substantially in the range of 5 Hertz and 500 Hertz from the second transmitter. The system preferably coherently delivers audio from the audio source to the first transmitter and the second transmitter for providing enhanced amplification of the audio source by simultaneously transmitting the audio source to the first transmitter and the second transmitter.

[0052] However the system preferably can in one form coherently deliver audio from the audio source to the first transmitter and the second transmitter for providing enhanced amplification of the audio source by simultaneously transmitting the audio source to the first transmitter and the second transmitter.

[0053] Preferably the system coherently delivers audio from the audio source to the first transmitter and the second transmitter for providing enhanced amplification of the audio source by the control module 31 separating the audio signal substantially in the range of 5 Hertz and 500 Hertz to the second transmitter 32.

[0054] The separate enhancing amplifier speaker system can be a separate amplifier speaker system with a wireless receiver for receiving audio signal from the second transmitter of the output means of the control module.

[0055] The separate enhancing amplifier speaker system is a separate subwoofer system 51 with a wireless receiver for receiving audio signal from the second transmitter of the output means of the control module 31.

[0056] In Figure 1 the control module 31 receives input from portable source 21, 22 by wireless transmission and outputs signal through FM transmitter 33 to the vehicle FM radio for receipt on particular input FM wavelength and output to its speaker system 42. At the same time the control module 31 outputs to the amplifier 32 of the second speaker system being a sub-woofer system 51. By the coherent transmission from portable source 21, 22 being the mobile phone or the like, which does not need to be tethered or otherwise physically connected, to the first speaker system 41, 42 of the vehicle but enhanced through the second speaker system 51. This is achieved without the need for hard installation and can be readily powered from auxiliary power through power connection 35.

[0057] Referring to Figure 2 the flow is altered in that a capacitor is used to enhance power of signal and the control module 31 can transmit to first speaker system while also outputting to an audio decoder module 33 that directs the amplifier 32 of the secondary speaker system 51.

[0058] In Figure 3 there is an enhancement of the secondary speaker system in that the amplifier includes an air port for cooling the amplifier while it drives the sub-woofer secondary speaker 51. This air port can also be used to enhance audio as a sound chamber.

[0059] In Figure 4 there is shown the system of Figure 3 but without the capacitor.

[0060] The separate enhancing amplifier speaker system is a separate subwoofer system with a wireless receiver for receiving audio signal substantially in the range of 5 Flertz to 500 Flertz from the second transmitter of the output means of the control module.

[0061] The system coherently delivers audio from the audio source to the first transmitter and the second transmitter for providing enhanced amplification of the audio source by transmitting the audio source to the first transmitter and the second transmitter in a respective delayed manner depending on the difference in processing of the signal in the first speaker system and the second enhancing amplifier speaker system.

[0062] Referring to the embodiment shown in Figure 3 there is a wireless enhanced sound system the separate enhancing amplifier speaker system is a separate subwoofer system which includes (1) an amplifier for the subwoofer 32 (2) a subwoofer speaker 51 (3) an air-port for cooling the subwoofer amplifier 37 wherein the air-port is tubular with a radius substantially in the range of 5 cubic centimetres to 50 cubic centimetres and the air-port is adapted with the subwoofer speaker to enhance the audio of the subwoofer speaker.

[0063] The tubular shape of the air-port can be of any cross-sectional shape including circular, square, irregular or multisided.

[0064] The separate subwoofer system is powerable through a power point 35 on the vehicle and preferably the power point on the vehicle is a cigarette lighter port or similar vehicle auxiliary power port.

[0065] In each embodiment there is provided a wireless enhanced sound system for enhancing a vehicle with a first speaker system comprising a wireless control unit and a portable separate subwoofer system wherein the control unit includes a control module including: an input means for receiving an audio input wirelessly from an audio source; and an output means having a first transmitter for wirelessly connecting to the first speaker system; and a second transmitter able to wirelessly connect to the subwoofer speaker system; wherein the wireless enhanced system coherently delivers audio from the audio source to the first transmitter and the second transmitter for providing enhanced amplification of the audio source.

[0066] In use the method of enhancing a vehicle sound system including the steps of: a) Providing a portable subwoofer system having a receiver for receiving audio signal wirelessly; b) Providing a control module including an input means for receiving an audio input wirelessly from an audio source; and an output means having a first transmitter for wirelessly connecting to the amplifier of the first speaker system; and a second transmitter able to wirelessly connect to the separate enhancing amplifier speaker system; c) coherently delivering audio from the audio source to the first transmitter and the second transmitter for providing enhanced amplification of the audio source by transmitting the audio source to the first transmitter and the second transmitter in a respective delayed manner depending on the difference in processing of the signal in the first speaker system and the second enhancing amplifier speaker system.

[0056] The method preferably provides a separate enhancing amplifier speaker system which is a separate subwoofer system including an amplifier for the subwoofer, a subwoofer speaker and an air-port for cooling the subwoofer and amplifier wherein the air-port is tubular with a radius substantially in the range of 5 cubic centimetres to 50 cubic centimetres and the air-port is adapted with the subwoofer speaker to enhance the audio of the subwoofer speaker.

[0057] Referring to Fig. 5 there is shown the configuration of the articles of the system in which the mobile phone 21 or other digital communication device can have a playlist and be able to communicate by Wi-Fi or Bluetooth to the car radio system 41 or to the Drive Buddy™ control unit 31. The control unit can receive and transmit to the car radio 41 which is connected by wire or wirelessly to the normal amplifier 42.

[0058] Flowever apart from the normal amplifier the system allows for a portable subwoofer to be installed and controlled by the Drive Buddy™ control unit 31 in unison and complementing the normal amplifier 42. This is achieved by the subwoofer control 32 having wireless receiver for receiving communication from the control unit 31. The subwoofer control 32 which can include an amplifier to drive the sub-woofer 51 will be attached to the subwoofer with wired connector. The connector would be on the rear of the device and subwoofer and as such would not be visible to the user.

[0059] Referring to Figure 6 there is a first version of the Drive Buddy™ control unit 31. This comprises a body 11 shaped to hold a rectangular screen 62 and a domed top wherein between the top curved surface and the screen are control buttons.

[0060] The control buttons include a multi-turn control 63 which allows for scrolling through the listings as displayed on the screen and as communicated from the control unit memory or the mobile phone memory. Therefore the system allows ready interaction of your mobile devices as you move into the vehicle without difficulty. The multi-turn control 63 is mounted centrally so that it is equally accessible from the left or right side.

[0061] Other buttons in the Drive Buddy™ control unit 31 are a play/stop/skip button 64 and a phone connect button 65 for allowing two communication by Wi-Fi or Bluetooth between the phone and the control unit. One part of the buttons can relate to music commands while the others relate to phone commands. However the operation can be intertwined with overlap of the modes associated with the button controls.

[0062] The Drive Buddy™ control unit 31 as shown in Figure 9 can be shaped and sized to fit within the steering wheel 80 of the vehicle and therefore be easily retrofitted and easily handled by the driver in similar ways to other steering wheel mounted controls. The device if located on the steering wheel 80 should be positioned in the inside part of the steering wheel as it is more comfortable and less invasive. The multi-turn control is located close to the steering wheel as it is simpler to reach and more stable. There should be sufficient clearance around the multi-turn control for the fingers to operate it comfortably.

[0063] However by having such connection, the driver of the vehicle can readily turn on the phone, which will already be set-up by Wi-Fi or Bluetooth to the car radio 41 and allow ready hands free communication. This is possible with the use of the driver’s phone and not requiring the need for the vehicle to be purchased and set up with inbuilt [0064] Also the system is able to follow the radio and use the normal amplifier while processing the signals to control the subwoofer in harmony and provide an improved audio sound. An improvement of the audio system can be readily achieved by the wireless interaction of the radio with the control system and the driving of the subwoofer.

[0065] Referring to Figure 12 there is shown a Drive Buddy control unit 31 in which at the heart of the control is a Bluetooth SOC microcontroller. This can be powered by DC power source 72 through connecting plug 73 which is also fed to a 5V regulator 74. The controller 71 has temperature control by the temperature monitor 76. The controller undertakes its operations by activation of the push button on/off and pairing 75 and output and by two communication with the FM transmitter receiver 33 to the car radio and/ or digital communication means 21. The result is to instruct and control the audio amplifier [0066] This Bluetooth system on chip is the master device and will provide the following elements: • Bluetooth pairing with audio source • Bluetooth pairing of multiple Drive Buddy units with remote control • Bluetooth pairing of multiple Drive Buddy units to a single audio source • Bluetooth streaming from audio source • Bluetooth audio commands (Play, Pause, Prev, Next, etc) pass through from Bluetooth Remote to audio source • Remote control commands via FM transceiver • System status via LED indicators • Audio output volume control • Amplifier shutdown power control • System power monitoring to prevent over-discharge of car battery • Over the air firmware upgrades • LED status indication: • System operating • Bluetooth Connection • Car Battery low • Weak signal indication (Bluetooth out of range) [0067] Referring to Fig. 13 there can be a separate or integral Bluetooth remote control and subwoofer display in which the Bluetooth SOC microcontroller receives power from a battery charger 79 powered by USB connection 22 and which can feed to storage lithium battery 86. The input through the audio and phone control buttons 63, 64 and microphone 24 into the controller can have output to display 77 which is locally complemented to ambient light in response to the input of the ambient light sensor 78.

[0068] Bluetooth remote control can be rechargeable via the USB port and can provide the following features: • Microphone audio stream to multiple paired main units • Bluetooth Call answer • Bluetooth Call end • Bluetooth audio commands (Play, Pause, Prev, Next, etc) • FM frequency select • Over the air firmware upgrades • LED status indication: • FM frequency • Call in progress • Bluetooth Connection • Battery level • Weak signal indication (Bluetooth out of range) [0069] Referring to Fig. 14 there is shown the amplifier 32 having amplifier control 92 feeding to the speaker via LC filtering 97 and speaker connector 98. The amplifier control 92 is powered by 12V to 36V DC converter 91 and receives dual channel differential audio input 95 but can be overridden by mute signal 93 if required.

[0070] The amplifier is configured by the micro-controller firmware however, switches will be used to select: • Output Impedance • Frequency Filtering cross-over A mute signal will ensure the amplifier is silent during power up, connection and configuration to eliminate spurious pops and clicks.

[0071] Referring to Fig. 15 there is a version without amplifier but with Display. The systems configuration and display is designed to include: ♦ logo splash screen ♦ Drive Buddy branding ♦ Telephone ♦ Audio source selection
