Abstract
The utility model belongs to the information storing device. A speech recording and playing circuit which takes a TC8832F speech integrated circuit as a main circuit and a control circuit which takes an HIBO-200 integrated circuit chip as a main circuit are connected together. The speech recording and playing circuit is connected with a dynamic memory, and the control circuit is connected with a keyboard controller and a liquid crystal display device. The utility model is a novel speech recording and playing device, and the recording and playing time of each section of speeches can be regulated according to real requirements. The utility model makes users feel convenient and prevents the speeches from being cut off suddenly and prevents the waste of sources.
Description
The utility model belongs to a kind of information storage device.
Random digit recording playback product in prior art for example digital speech reminiscences and digital phone is answered record device etc., their each section record lengths all are the regular lengths of setting, and people are when using this series products, each record length that requires is different in size, therefore the fixing recording/displaying device of this class time length brings very big inconvenience to the user, what this series products adopted is to be the recording playback means of control unit with the section, therefore can't overcome this intrinsic shortcoming.
The purpose of this utility model is to adopt the technology of look-alike disk management, design a kind of every section record length to be adjusted at random, automatically free segment length's speech digit recording/displaying device of managing.
Embodiment of the present utility model is to adopt the audio record circuit of auto-adaptive increment modulation technique to be connected with control circuit based on the HIBO-2O0 integrated circuit (IC) chip, on audio record circuit, connect a dynamic memor again, making dynamic memor by control circuit is that unit is divided into some very little sound sections with the point, make its sound section distribute chained list, connecting key disk controller and LCD on control circuit with corresponding multistage voice.
The utility model has the advantages that provides a kind of speech recording and reproducing of novelty device, and the recording playback time of every section voice can be adjusted with actual needs, allows the user feel very convenient, has avoided voice to be blocked suddenly and the wasting of resources.

Embodiment:
Control circuit adopts the HIBO-200 large scale integrated circuit design, by the control in the external world, finishes timing recording and control, and drives liquid crystal display displays time and corresponding various functional symbol.
Audio record circuit is made of TC8832F speech IC and peripheral circuit, and it adopts the work of 640KHZ crystal.Voice signal is coupled to audio input end by the microphone input through O6 during recording, and there is microphone amplifier inside, changes through A/D again.In dynamic memor U2DRAM, audio record circuit can adopt as Fig. 3, Fig. 4, Fig. 5 or different structure shown in Figure 6 with sound signal storage, and it is applicable to and connects any dynamic memor.
After powering up during use, control circuit formats dynamic storage, and it is divided into a plurality of sections (for example 64 or 128), and sign is set, at memory head foundation sound section allocation table.When beginning to record, control circuit is at first noted down the segment number of current recording, and inquiry sound section allocation table, find first to be masked as empty sound section, beginning this of the digital signal typing section with voice, is non-NULL with this segment mark after record is full, and inquiry is next again is masked as empty sound section, by that analogy, all record is full or stop recording by end key until sound section of institute.At this moment the institute with this section voice is recorded in the sound section allocation table for sound section in order.During the beginning playback, control circuit at first finds the voice segment number that will put, and the sound section chained list according to behind the segment number comes out speech data taking-up and playback in the corresponding internal memory of this section successively.When needing deletion, control circuit at first finds the voice segment number that will delete, and according to the sound section chained list behind the segment number, the sign with each section changes sky into by non-NULL successively, so that use later on, again the sound section chained list cancellation behind the segment number.
Claims (1)
1, a kind of free segment length's speech digit recording/displaying device, it is characterized in that it is to be connected with control circuit based on the HIBO-200 integrated circuit (IC) chip being main audio record circuit by the TC8832F speech IC, on audio record circuit, connect a dynamic memor, connecting key disk controller and LCD on control circuit again.
