QX-RFLM-10 sound recorder module (Item No. #D01, #D11)
|
This is a 10 seconds solid state sound recording IC. A 10 second sound can be recorded many times. The sampling rate is 6.4 kHz. S The module is measured 45mm by 25mm by 15mm. To form a complete sound recording and replaying device, you require three switches (one for recording, one for re-play and one for stop), one LED to indicate recording status, one speaker (8 Ohms) and one electret microphone. The module requires a power supply from 4.5 V to 6.5 V DC. In recording and replaying modes, current consumption is typically 25mA. In idle mode, the current drops to 0.05 m A. |

QX-RFLM-20 sound recorder module (Item No. #D02, #D11)
|
It is a 20 seconds solid state sound recording IC. The sampling rate is 6.4 kHz. The module is measured 45mm by 25mm by 15mm. To form a complete sound recording and replaying device, you require three switches (one for recording, one for re-play and one for stop), one LED to indicate recording status, one speaker (8 Ohms) and one electret microphone. For this module, the 20 seconds recorded sound can be programmed to replay once or continuously after a PLAY button is pressed The module requires a power supply from 4.5 V to 6.5 V DC. In record and replay modes, current consumption is typically 30mA. In idle mode, the current drops to 0.05 m A. |

QX-RD1-20 sound recorder module (Item No. D-03, #D11)
|
It is a 20 seconds solid state sound recording IC. The sampling rate is 6.4 kHz. The module is measured 45mm by 25mm by 15mm. To form a complete sound recording and replaying device, you require three switches (one for recording, one for re-play and one for stop), one LED to indicate recording status, one speaker (8 Ohms) and one electret microphone. The 20 seconds can be divided into 4 segments. Each section can be replayed only once after a PLAY button is pressed. The module requires a power supply from 4.5 V to 6.5 V DC. In record and replay modes, current consumption is typically 25mA. In idle mode, the current drops to 0.05 m A. |

APR9600 sound recorder module (Item No. #D04)
|
APR9600 is sound record/replay IC incorporating flash analogue storage technique. Recorded sound is retained after power supply is removed from the module. The replayed sound exhibits high quality with a low noise level. Sampling rate for a 60 second recording period is 4.2 kHz that gives a sound record/replay bandwidth of 20Hz to 2.1 kHz. However, by changing an oscillation resistor, a sampling rate as high as 8.0 kHz can be achieved. This shortens the total length of sound recording to 32 seconds. Total sound recording time can be varied from 32 seconds to 60 seconds. The IC can operate in one of two modes: serial mode and parallel mode. In serial access mode, sound can be recorded in 256 sections. In parallel access mode, sound can be recorded in 2, 4 or 8 sections. The IC can be controlled simply using push button keys. It is also possible to control the IC using external digital circuitry such as micro-controllers and computers. |

The APR9600 experimental board is an assembled PCB board consisting of an APR9600 IC, an electret microphone, support components and necessary switches to allow users to explore all functions of the APR9600 chip. The oscillation resistor is chosen so that the total recording period is 60 seconds with a sampling rate of 4.2 kHz. The board measures 80mm by 55mm. |
