Definitions
- Microphone device incorporated in computer network
- the present invention relates to a microphone device incorporated in a network so as to enable a user to broadcast a desired sound.
- chime sounds that indicate the start and end of broadcasting are used in school broadcasting.
- This chime sound is broadcast by operating the microphone terminal of the broadcasting equipment.
- the chime sound generated from the sound source is built into the microphone terminal.
- the problem here is that the chime recorded on the ROM is a so-called fixed voice. Therefore, if the user wants to use the original chime sound according to the request, either create a ROM that stores the chime sound that meets the user's request individually, or use the desired chime sound. It is necessary to prepare a separate audio playback device to generate sound. However, this not only increases costs, but also requires time and effort to create a chime sound.

- FIG. 2 is a diagram schematically showing a configuration of one embodiment of a microphone device according to the present invention.
- FIG. 3 is a diagram showing an example of a configuration of a flash ROM incorporated in the microphone device shown in FIG.
- FIG. 4 is a flowchart illustrating the operation of the network system shown in FIG.
- FIG. 1 schematically shows one embodiment of a network system incorporating a microphone device according to the present invention.
- the microphone device 1 according to the present invention is connected to one personal computer 3 via a local area network (LAN) 2. That is, the microphone device 1 is one terminal connected to the local area network 2.
- LAN local area network
- the personal computer 3 is provided with a terminal connected to an external sound source so that desired sound data can be created and stored on the hard disk, and the sound from the sound source can be transmitted to the desired sound data. It has software for processing as audio data and storing it on the hard disk.
- the microphone device 1 of FIG. 1 includes a microphone element 11 for supplying a broadcast audio signal of a speaker to a broadcasting device (not shown) including an amplifier and a speaker, and a local device.
- Network interface 12 connected to the area network 2 and a flash ROM 15 connected to the network interface 12 via the reception buffer 13 and the decoding unit 14. .
- Hula The area selection button 16 and the display 17 are connected to the flash ROM 15.
- the flash ROM 15 is divided into a plurality of areas, and audio data sent from the personal computer 3 via the local area network 2 is stored in a plurality of areas of the flash ROM 15. Written on one of them.
- FIG. 3 shows a case where the flash ROM 15 is divided into four areas A1 to A4, and audio data for generating different chime sounds is stored in each area.
- audio data for generating a chime sound for broadcasting start is stored under the name of “broadcast start (1)”
- audio data of broadcast start (1) is paired.
- the audio data to generate the chime sound for the end of broadcast is stored under the name of “End of broadcast (1)”.
- the flash ROM 15 mounted on the microphone device 1 can be rewritten by the personal computer 3. It is.
- the procedure for realizing this will be described with reference to FIG. 4, taking as an example a case where audio data for generating a desired chime sound is written from the personal computer 3 to one area of the flash ROM 15.
- step S1 the power switch of the microphone device 1 is turned on. In response, the microphone device 1 enters a connection accepting state. Therefore, when the user writes the sound data of the chime sound in one of the areas of the flash ROM 15, that is, specifies the address of the area, the sound data for generating the chime sound is received from the personal computer 3. As a result, the reception buffer 13 becomes operable, and the microphone device 1 enters a data waiting state according to the TCPZ IP protocol.
- step S2 the user prepares voice data for generating a desired chime sound in advance using the personal's convenience store 3, and stores the voice data as one file on the hard disk.
- the file format of the audio file is arbitrary, but for example, a commonly used waV file Good.
- step S3 the transfer software installed in the personal computer 3 is used to execute step S3.
- the audio file stored in the hard disk in step 1 is converted into a file format suitable for the microphone device 1.
- the network address together with the audio file name is converted into a file format suitable for the microphone device 1.
- the file format suitable for the microphone device 1 is, for example, a header that describes the file information of the audio file (in the case of a waV file, the header information of the wav file) is deleted and transferred.
- the audio data thus created is encoded, for example, by band division adaptive differential pulse code modulation (SB-ADPCM), and the encoded data is written to a buffer as transfer data. Note that a data length is inserted at the beginning of the transfer data.
- the transfer data written in the buffer in this way is transferred to the microphone device 1 having the network address specified in step S3 according to the TCP / IP protocol (step S4).
- the transfer data transferred from the personal computer 3 is received by the microphone device 1 in step S5, and the received transfer data is written to the reception buffer 13 via the network interface 12.
- the transfer is performed in several steps, and the number of received data is counted by referring to the data length inserted at the head of the received data. Is written.
- the data written in the reception buffer 13 is sent to the decoding unit 14 and decoded, and the audio data before modulation is reproduced.
- the reproduced audio data is written to the designated area of the flash ROM 15 (step S6).
- the receiving buffer 13 is released, and the display 17 displays the name of the stored audio data and the area into which the audio data was written.
- the user 1 transfers the desired chime sound created on the personal computer 3 to the microphone device 1 via the local area network 2 and It can be stored in the flash ROM 15 of the device 1. Since the flash ROM 15 has a plurality of areas, the user can store audio data of a plurality of different chime sounds. Therefore, when starting broadcasting, the user selects an area in which audio data of a desired chime sound is stored, for example, area A1, using the area selection button 16, and then starts broadcasting from area A1.
- the audio data named “1)” is read, decoded by the decoding unit 14 and given to the broadcasting device, so that a chime sound indicating the start of the broadcast is broadcast. The same applies when notifying the end of a broadcast.
- the present invention is not limited to such an embodiment.
- the area of the flash ROM 15 to which the audio data created in the personal computer 3 is to be written can be specified remotely from the personal computer 3.
- the local area network 2 may be replaced by an in-net network.
- TCP / IP the network protocol. This is because updating via the Internet becomes possible and the maintainability of the equipment is improved.
- other protocols can be used.
- the flash ROM 15 any writable and readable storage medium can be used.
- FIG. 1 shows a case where one microphone device and one personal computer are connected to a network, but the present invention is not limited to this. In the case of a plurality of personal computers, a plurality of microphone devices and one personal computer, a plurality of microphone devices and a plurality of personal computers are included.
- the data written to the flash ROM 15 may be modulated data sent from the network instead of the decoded audio data. In this case, since the encoded data is written as it is, memory can be saved.
- the microphone device according to the present invention may be used in a broadcasting system that performs audio broadcasting via a network.
- the broadcast system network and channel It can be shared with the network used to transfer the sound.
- the microphone device does not need to decode the audio data, and the encoded audio data may be transmitted as it is during broadcasting, so that the processing is simplified.
- the present invention incorporates a microphone device having a writable / readable storage means into a computer network. So
- Desired audio data can be created using an existing computer, transferred to a microphone device and stored in a storage means, so that a plurality of different audio data can be easily and specially stored in a special device. Can be set to the microphone device without preparing
- the audio data can be written to the storage means of the microphone device remotely via a computer network, and the writing of the storage means is easy.
