DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for recording sound data in a sound recorder which records a voice message and can reproduce the message at any time.

[0002]

2. Description of the Related Art Portable sound recorders (voice recorders) capable of recording voice messages and reproducing them at any time have been commercially available, and are used for games, and are also practically used as memos. I have. Further, as described in JP-A-1-127392,
It is known that a sound recorder having a function of recording and reproducing digital audio data is incorporated in a card for communication or the like. Japanese Patent Application Laid-Open No. 1-127392 discloses a device for recording voice data on the card (voice synthesis card), in addition to a voice signal from a microphone, a BGM (background music) device or a cassette tape. It is described that sound can be recorded. In addition, as described in Japanese Patent Application Laid-Open No. 60-151595, a postcard is coated with a magnetic material to have a voice recording function, and recording and reproduction are performed by a dedicated vending machine. Are known.

[0003]

The conventional portable sound recorder merely records and reproduces the user's voice as it is, and lacks interest. JP-A-60-15
The same applies to the case of the voice postcard described in Japanese Patent Publication No. 1795, which also lacks interest because the voice of the user is simply recorded as it is, and the recording and reproduction are performed by a dedicated vending machine, so the usage range is limited. Can be Further, Japanese Patent Laid-Open No.
In the case of the speech synthesis card described in US Pat.
The user's voice can be mixed with the BGM and recorded, but the user's voice and the BGM can be mixed.
It does not have a function that can independently adjust the volume of each, and it does not have a function to output the mixed sound data as sound for confirmation before recording, so that various users Can't respond to preference.

Therefore, the applicant of the present application has previously described a device which can record a user's voice by mixing it with a BGM in a sound recorder, and furthermore, can record with a variety of features and rich in interest and unexpectedness. Developed a sound data recording device that can independently adjust the volume of the input user's voice and BGM before mixing, and output and check the mixed and synthesized sound data before recording.
Filed a patent application (submitted on September 30, 1997). This sound data recording device is as shown in FIG. 7 and includes a CPU 30 for performing system control of the entire device and a memory 31 for storing a control program. The CPU 30 further includes an input / output register 32 , A bidirectional connection with the depositing unit 40, the operation switch unit 41, the dispensing unit 42, and the coin counter 43, and a personal computer 33, a recording / reproducing IC 53 and each electronic volume IC 5 via an input / output register 32.
2, 57 and 60 are bidirectionally connected to the signal processing unit 63 connected to the writing terminal 35, and output for processing control signals for controlling the motor of the ejection unit 42 and the like. The drive processing unit 65, the sound quality conversion IC 55, and the analog switches 56 and 59 are connected to output control signals. The personal computer 33 displays the guidance screen on the display monitor 3, stores BGM as the second sound data and the guidance sound to the speaker 401 of the receiver 4, and transmits these sound data to the amplifier 5.
1. Output to the mixer 58 via the electronic volume 52. The personal computer 33 is connected to an input / output device (keyboard) 36 for controlling the personal computer. Microphone 40
The voice message as the first sound data input from 2 is temporarily stored in the memory 54 via the amplifier 403, and is reproduced by the recording / reproducing IC 53 at a timing controlled by the CPU 30. The reproduced sound passes through the sound quality conversion IC 55 according to the user's selection.
Alternatively, the signal is output to the mixer 58 via the electronic volume 57 by-passing. Also, BGM and guidance sound as the second sound data are output from the personal computer 33 to the mixer 58 via the amplifier 51 and the electronic volume 52.
Then, the first sound data and the second sound data are superimposed (mixed) by the mixer 58, and by switching the analog switch 59, any one of the speaker 401 of the receiver 4 and the housing speaker 34 as sound data output means is output. Or to the write terminal 35. That is, during recording, the sound data mixed and synthesized by the mixer 58 is supplied to the amplifier 62 and the signal processing unit 6.
The signal is transmitted to the writing terminal 35 via the third terminal 3 and written to the sound recorder 20. When the user confirms the synthesized voice before writing, the analog switch 59 is used.
Is switched, and the output of the mixer 58 is transmitted to the speaker 401 of the receiver 4 via the amplifier 66. And
When the guidance voice is output from the personal computer 33, only the sound data from the personal computer 33 is input to the mixer 58, the analog switch 59 is switched according to the content of the guidance, and the voice data of the guidance voice is passed through the amplifier 66 to the receiver. 4 is transmitted to the speaker 401 (in the case of guidance for operation contents) or to the cabinet speaker 34 via the electronic volume 60 and the amplifier 61 (in the case of guidance for demonstration).

According to the sound data recording apparatus according to the above-mentioned application, the sound of the user can be mixed with the BGM and recorded on the sound recorder. In addition, a plurality of types of sound data such as BGM are prepared in advance, and By making it possible to select freely, a more valuable sound recorder can be obtained according to the content, purpose, and season of the message, and the user can change the sound quality of the voice message and record it. It is possible to obtain a more unexpected sound recorder. The volume of the input user's voice and BGM can be independently adjusted, and the mixed and synthesized sound data can be output as a sound for confirmation before recording. Sound data can be selectively output from a receiver or a housing speaker. However, this device uses two electronic volumes 52 and 57 in order to be able to independently adjust the volume of the user's voice and BGM,
Also, in order to selectively output the user's voice as the first sound data, the BGM or the guide voice as the second sound data, and the mixed and synthesized sound data to the writing terminal or each speaker. , Using an analog switch, and using another electronic volume 60 for adjusting the volume of the guidance voice to be output to an external speaker. These electronic volume and analog switch increase the manufacturing cost. It is a factor.

Accordingly, in the sound data recording device,
It has been a problem to reduce the number of circuit components to be used to reduce the cost, to simplify the circuit configuration and to reduce the number of failures.
