Abstract

The utility model relates to a tape or record audio converting device. The audio converting device comprises a rotating mechanism, an analog/digital signal converter (ADC) and a computer and is characterized in that the rotating mechanism converts a tape or a record into an analog audio signal by a magnetic head and a pick-up head; the ADC converts the analog signal into a digital signal; and then the digital signal is stored into a corresponding media through computer software. By the scheme, the tape/record audio is converted to the digital format and then stored in a computer; besides, distortion or missing is reduced in the process of rerecording; and the signal quality is not lowered after multiple times of playback.

Description

Audio conversion device

Technical field

The utility model relates to a kind of audio conversion device, further relates to the song of tape/disc the inside is transcribed the device of preserving in the computer carrier.

Background technology

Existing collection disc for a long time dare not be used for a long time because of the use short limitation of receiving a mandate, or for a long time without tape because of maintaining the improper magnetic permanent damages that comes off.One of solution is to transfer the tape/canned music of larger volume to the digital music storage, makes that the storage time is more permanent and tonequality is higher, plays more conveniently and collect for a long time loved music by PC or MP3.

Some rerecording device major defects of Chu Xianing are in the prior art:

Phonotape and videotape produces distortion or ratio disappearance in the transcription; Repeatedly the playback meeting reduces signal quality.

Summary of the invention

In view of above content, be necessary to provide a kind of device that can realize tape or disc are carried out digital conversion.

The utility model provides a kind of tape or disc audio conversion device, comprises by rotating mechanism analog/digital signal conversion device ADC and computing machine; Wherein rotating mechanism transfers tape or disc to simulated audio signal by magnetic head and pickup, and ADC is a digital signal with analog signal conversion again, by computer software digital signal is being stored in the corresponding medium.

Wherein adopt the 48KHZ sampling rate of two-channel, and 16bit sample format ADC converting system, transcribing of this device can reach DVD tonequality.

Compared with prior art, of the present utility modelly be a little:

1. the sampling of two-channel of the present utility model has realized the collection of sound signal high-quality.

2. in each switch process of the present utility model, conversion efficiency is higher, has reduced the distortion and the deficient phenomena that produce in the transfer process.

Description of drawings

The utility model will be further described in conjunction with the embodiments with reference to the accompanying drawings:

Fig. 1 is the transfer process figure of the utility model tape or disc audio conversion device.

Fig. 2 is the realization basic circuit diagram of the utility model tape or disc audio conversion device.

Embodiment

See also Fig. 1 and Fig. 2, the utility model provides a kind of tape or disc audio conversion device, comprise and pass through rotating mechanism, analog/digital signal conversion device ADC and computing machine: wherein rotating mechanism transfers tape or disc to simulated audio signal by magnetic head and pickup, ADC is a digital signal with analog signal conversion again, by computer software digital signal is being stored in the corresponding medium.

Wherein adopt the 48KHZ sampling rate of two-channel, and 16bit sample format ADC converting system, transcribe and to reach DVD tonequality.

As depicted in figs. 1 and 2, at first by wheelwork, read magnetic recording information and, the earphone simulated audio signal is amplified by motor-driven and pre-driver; After analog/digital signal conversion device ADC acceptance, simulated audio signal is passed through analog to digital conversion, produce digital signal, import in the computing machine through data line, corresponding encoded through computer software, but be transformed into the corresponding format file of playing back music, and be stored in the corresponding media, as u dish, mp3 etc.

The utility model is primarily aimed at the improvement that tape/the disc audio conversion device is carried out, the above only is the utility model preferred embodiment, non-so promptly limit to claim of the present utility model, so the simple and easy variation and the equivalent transformation of doing with the utility model instructions and graphic content such as all should be contained in the claim of the present utility model.

Claims

1. tape or disc audio conversion device comprise by rotating mechanism analog/digital signal conversion device ADC and computing machine; It is characterized in that: described rotating mechanism transfers tape or disc to simulated audio signal by magnetic head and pickup, and ADC is a digital signal with analog signal conversion again, by computer software digital signal is being stored in the corresponding medium.
