Amusement equipment is entertainment and stimulating because it belongs to entertainment products, so it is warmly welcomed by people. In the past amusement equipment, it is only a simple action type, and the fun is like a little less fun of communication. Now, with the advent of voice chip products, many changes have been made to amusement equipment. Amusement equipment, plus voice function, no doubt, let the equipment and play a more communication path between the guests, the original equipment will also be voiced. It gives people more fun.

Our company has been engaged in the voice industry for nearly 10 years, and has made numerous voice products. Among them, there are many kinds of voice circuit board, suitable for amusement equipment. Below, I will apply these voice circuit board to the amusement equipment, and give a brief introduction to everyone.

Application case: a shooting machine

The shooting machine is undoubtedly a more stimulating type in amusement equipment. When the tourists buckle the plate buckle and hit the target, there is a voice prompts on the target side, which is really very enjoyable for tourists to shoot.

For this kind of voice product, how to choose a solution to achieve it? Below, our company provides several implementations for your reference.

Program 1: voice chip, it is suitable for occasions of short seconds, one-off, voice cannot be changed. Cheap price

For example, NV180C, at the 6K sampling rate, can contain 180 seconds of voice, and the content of the speech can include all the voice of the above table. In addition to the general sound effect, such as laughter, applause can also be well displayed. In the case of 8K sampling, the sound quality is also good.

Scheme 2: voice module, which is suitable for a long time. It can not only be repeated erasure (through a special downloader), but also can modify the voice content freely through the software. In addition, it has good sound quality and high cost performance.

There are several varieties of this module.

1) N9100 voice module

The module integrates MCU and decoder chip for control, and the sound quality level reaches MP3 sound quality. The maximum storage time is up to 60 minutes. No Downloader, direct USB replacement voice is more advanced and convenient than the general module in the market.

There are 4 modes of operation for modules:

A. button function: 10 ADKEY keys, a button corresponding to a function, you can request the corresponding.

B. microcontroller serial port serial port function: can be divided into 239 paragraphs. It only needs 2 I/O ports to play a random voice in the module.

C.UART serial port function: up to 9999 paragraphs. Specified time, specified repertoire play, insert.

D. standard mode: similar to MP3, play / pause, last, next, volume plus, volume reduction, stop.

2) N9101 card module

The module uses SD card as storage medium, so it is very easy to replace voice. It can be completed with only one card reader. Or with our latest revision of the USB interface module can also be. Voice format: MP3. Capacity support: 32M - 1G.

This is a very good sound quality. There are 4 ways of working:

A. button function: 10 ADKEY keys, a button corresponding to a function, you can request the corresponding.

B. microcontroller serial port serial port function: can be divided into 239 paragraphs. It only needs 2 I/O ports to play a random voice in the module.

C.UART serial port function: up to 9999 paragraphs. Specified time, specified repertoire play, insert.

D. standard mode: similar to MP3, play / pause, last, next, volume plus, volume reduction, stop.

3) N9200 music module

Direct USB copy content in. Time from: 10 seconds - dozens of hours optional. The scheme is compact and can provide modules, and can also provide module solutions to meet the needs of customers in all directions. It can support TF card, U disk, flash at the same time, and switch at any time.

A. button function: 10 ADKEY keys, a button corresponding to a function, you can request the corresponding.

B. microcontroller serial port serial port function: can be divided into 239 paragraphs. It only needs 2 I/O ports to play a random voice in the module.

C.UART serial port function: up to 9999 paragraphs. Specified time, specified repertoire play, insert.

D. standard mode: similar to MP3, play / pause, last, next, volume plus, volume reduction, stop.

4) NR9600 music module (also supports flash, U disk, TF card storage medium).

Compatible with all functions of N9200 module, and adding real-time recording function, it can connect MIC live recording to MP3 file or AUX input and output.

A. button function: 10 ADKEY keys, a button corresponding to a function, you can according to their request to receive the corresponding, recording, playing.

B. microcontroller serial port serial port function: can be divided into 239 paragraphs. It only needs 2 I/O ports to play a random voice in the module.

C.UART serial port function: up to 9999 paragraphs. Designated time, designated tracks play, insert, you can record, play, switch, insert function.
