1. Field of the Invention
The present patent document relates generally to vinyl record turntables and more specifically to a method and system for recording analog audio from a vinyl record turntable to a handheld computing device.
2. Background of the Related Art
Handheld computing devices, such as Apple®'s iPad®, iPod® or iPhone®, have become popular devices to store and play back music. However, there is no easy way to get music from conventional vinyl records onto handheld computing devices directly without the aid of a personal computer. Handheld computing devices, such as the iPad® for instance, lack analog audio inputs, which prevents music from being recorded directly to the handheld computing device from the vinyl record turntable.
The current method of transferring music from a vinyl record onto a handheld computing device involves using a turntable equipped with a computer serial interface or a conventional turntable with a computer serial interface module coupled to the audio output of the conventional vinyl record turntable.
Specifically, the audio output of the turntable is communicated through the computer serial interface and into a personal computer. The audio input is then captured in digital format by music management software, such as Apple®'s iTunes® software. The digital copy of the vinyl record may then be transferred to the handheld computing device by attaching and synchronizing the handheld computing device to the music management software running on the personal computer. As can be ascertained, this method involves multiple steps and requires the use of a personal computer.
Therefore, there is a perceived need in the art for a method and device for transferring music from a vinyl record turntable digitally to a handheld computing device.
The present invention solves the problems of the prior art by providing a method and system for recording analog audio from a vinyl record turntable to a handheld computing device. Specifically, a digital way to record analog audio from a vinyl record into a handheld computing device without resort to use of a personal computer to facilitate the transfer is disclosed.
These and other features, aspects, and advantages of the present invention will become better understood with reference to the following description, appended claims, and accompanying drawings where:
Referring now to
The analog-to-digital converter 14 is connected to a serial interface device 16, such as a universal serial bus (“USB”) interface device. The serial interface device 16 formats the digital signal into a digital audio format, such as USB audio format, and transmits the formatted digital audio output to s handheld computing device's 18 USB serial interface, where the digital audio may be recorded to the handheld computing device's 18 memory.
Further provided, a microcontroller 20 may be included to communicate with the handheld computing device 18. Specifically, handheld computing devices 18, such as the Apple® iOS® family of devices, require authentication of the vinyl record turntable 10 as a valid peripheral, and set up of the serial interface device 16 communication link between the handheld computing device 18 and the serial interface device 16.
In the embodiment shown in
In the case where both a USB serial interface and a slow-speed or standard serial interface are present on the handheld computing devices 18, the initial communication (i.e. the authentication process and serial communication setup) with the handheld computing device 18 can be configured to occur through the slow-speed or standard serial interface of the handheld computing device's 18 serial interface or be configured to connect through USB formatted communication with the handheld computing device's 18 USB serial interface.

Additionally, a volume control may be located between the RIAA preamp 12 (or at the RIAA preamp) and the analog-to-digital converter 14 to adjust the recording level in either the first or second embodiments shown in
Referring now to
The turntable 10 includes all the standard features of a conventional record player, i.e. a housing 26, a rotating platter 28 with selectable speed, tone arm 30 with a pickup cartridge 32 connected to the analog audio output, etc. as is well known in the prior art and need not be described in detail herein.

Note that one advantage of the method and system of the present invention is that the audio output is transmitted to the handheld computing device 18 digitally, and not as an analog signal. This improvement allows the use of better components like analog-to-digital converters 14 that offer superior sound quality.
The method and system of the present invention may be integrated into the housing of a turntable 10 or housed in a separate housing that is external to the turntable 10.
Therefore, it can be seen that the present invention provides a unique solution to the problem of providing a solution to the problem of having analog music on a vinyl record, converting the music to digital format and transferring the digitally formatted music to a handheld computing device without the aid of a personal computer.
It would be appreciated by those skilled in the art that various changes and modifications can be made to the illustrated embodiments without departing from the spirit of the present invention. All such modifications and changes are intended to be within the scope of the present invention.
