Description

  The present invention relates to an apparatus that is connected to a mobile phone terminal and synthesizes and transmits a desired BGM / sound effect or the like to the voice of a speaker.

  Conventionally, as a device for synthesizing desired sounds such as BGM and sound effects into the voice of a speaker in a telephone call to bounce the conversation or enhance the mood, for example, Japanese Patent No. 2547676 discloses a telephone public Using a device connected between the line and the telephone, a sound effect stored in the device during conversation or a sound collected from a microphone converted to an arbitrary pitch is sent to the line to create a new conversation. It is disclosed that an acoustic function is provided. According to the present invention, it is possible to transmit by changing the voice of the sender, or to transmit while adding sound effects, but it is intended for fixed telephones and cannot be applied to mobile phone terminals. Since the device is interposed in the middle, there is a drawback that noise is generated in the call sound and the call quality is deteriorated.

  Japanese Laid-Open Patent Publication No. 2001-60993 discloses that BGM is reproduced and synthesized into speech during a call in a mobile phone terminal. This is because data is stored in advance in a data storage unit built in the mobile phone terminal. Playback is possible by storing or downloading and storing BGM data such as music data via a communication line. For this reason, a mobile phone terminal that does not include the mechanism cannot synthesize BGM, and has a disadvantage that it is not versatile.

Japanese Patent No. 2547676 JP 2001-60993 A

  As described above, what has been disclosed for the purpose of synthesizing BGM / sound effects and other sounds into a telephone conversation and sending them to the other party to bounce the conversation or enhance the mood. Anyone can easily install BGM into the voice of the talker simply by attaching it to various popular mobile phone terminals, such as those dedicated to fixed telephone lines or those that require dedicated mobile phone terminals. -It was not a device that could synthesize desired sounds such as sound effects and send them to the other party.

  The problem to be solved is that in a call on a mobile phone terminal, just connecting to the mobile phone terminal, anyone can easily synthesize and transmit the desired BGM / sound effect sound to their own voice, This is to provide a device that can bounce conversation and enhance the mood.

  Means taken by the present invention to solve the above problems are a data storage unit for storing sound data such as BGM and sound effects, and a selection unit for selecting desired sound data stored in the data storage unit. A microphone that collects the voice of the sender, a mixer circuit that synthesizes the voice data and the voice of the sender collected from the microphone, a connection terminal that is connected to the mobile phone terminal, and a control unit that controls them The sound data selected by the selection means is synthesized with the voice of the caller collected by the microphone and sent to the mobile phone terminal via the connection terminal.

  The sound data stored in the data storage unit is a digital signal, which is digital / analog (D / A) converted by the control unit and then synthesized with the voice of the sender.

  Furthermore, the connection terminal has a structure that can be connected to an earphone / microphone terminal of a mobile phone terminal or a structure that can be connected to an external extension terminal provided in the mobile phone terminal.

  According to the present invention, it is possible to synthesize a desired BGM / sound effect sound and the like and send it to the other party simply by attaching a small and light device to the mobile phone terminal. It makes it easy to bounce conversations and enhance mood.

  Details of the present invention will be described below with reference to the drawings. (1) is an apparatus main body according to the present invention, which is connected to a mobile phone terminal via a connection terminal (2) to an earphone / microphone terminal or an external extension terminal equipped on a currently distributed mobile phone terminal. . The device body (1) has a data storage unit (12) for storing sound data such as BGM and sound effects as digital data, a sound data selection circuit, a mixer circuit for synthesizing sound data collected by a microphone, In addition, digital / analog (D / A) conversion of sound data, a control unit (11) for controlling these, and a driving power source are incorporated. Note that the sound data stored in the data storage unit may be an analog sound, but it is preferable to convert it into digital data and store it because the capacity of the semiconductor memory that can be built into the device is limited. . (3) is a selection means, for example, a dial switch comprising a selection dial for giving a sound data number to the BGM selection section. (4) is a microphone unit, which is equipped with a sound collecting microphone for conversation and a BGM playback button (5). (6) is an earphone and speaks the other party's voice. If the device does not use the sound data mixing function, which will be described later, it can make a normal call while connected to a mobile phone terminal, as with hands-free call earphone sets that have been commercially available. I can do it.

  Hereinafter, details in use will be described with reference to FIG. 1A. The connection terminal (2a) extending from the device main body (1) is connected to the earphone / microphone terminal provided in the mobile phone. All mobile phone terminals that have been distributed in the past are equipped with a terminal that integrates an earphone and a microphone terminal, and this device equipped with a connection terminal that can handle the terminal depends on the type of the mobile phone terminal. It is possible to connect easily without doing. It should be noted that a call can be made in the same way as when a conventionally provided hands-free earphone set is connected, and there is no restriction on the call due to the connection of this apparatus.

  Next, when a desired BGM / sound effect sound is synthesized with its own voice and transmitted to the other party in a call state, a selection dial (3) as a selection means provided in the apparatus body (1) is set and desired. After selecting the BGM number, the play button (5) is pressed. The control unit (11) that has detected the pressing of the play button (5) acquires the sound data selected by the selection dial (3) from the data storage memory (12), and then digital / analog (D) of the data. / A) Perform conversion. The sound data converted into analog is synthesized by the voice of the speaker (user who uses the device) collected by the microphone built in the microphone unit (4) and the mixer circuit unit (13). And sent to the mobile phone terminal via the connection terminal (2a). Since the mobile phone terminal transmits the synthesized voice to the partner terminal, the voice of the BGM synthesized is delivered to the call partner.

  When synthesizing the BGM / sound effect, the control unit (11) does not acquire all the sound data and performs continuous sound data acquisition and D / A conversion in order to cope with the synthesis for a long time. The sound collected by the microphone may be continuously synthesized by the mixer circuit. If the call exceeds the recording time of one sound data, there are three ways to synthesize the same sound data again after the sound data ends, synthesize the next sound data, and stop the synthesis. However, these can be preset by the user. The setting is preferably performed using a mode change switch (not shown), but this is not restrictive. As for the selection dial (3), a knob type dial is used in the embodiment of the drawing. However, the present invention is not limited to this, and any dial can be used as long as an arbitrary data number can be designated. Good.

  As for the sound data such as BGM and sound effects stored in the data storage memory (12), several types of BGM and sound effect data have already been stored as initial storage data, but the microphone provided in the microphone unit (4). Any sound / sound effect or the like may be recorded / stored. In this case, the sound data can be added by setting the selection dial (3) at the recording position and then collecting desired sounds, music, effects, etc. from the microphone unit (4). . The play button (5) can be used to start and end the sound collection. When the play button (5) is pressed, sound collection is started, and the sound collected by the microphone is analogized by the control unit (11). / Digital (A / D) conversion is performed and stored as digital data in the data storage unit together with the data number.

  In the above embodiment, the earphone / microphone terminal is used as the connection terminal for connection to the mobile phone terminal. However, as shown in FIG. 1B, the connection terminal (2b) is connected to the external extension terminal provided in the mobile phone terminal. You may make it connect via. Even with this connection method, the synthesis operation and the process of sound data such as desired BGM and sound effects are not different from those of the above-described embodiments. When this connection method is used, it becomes possible to supply the driving power of the apparatus from the mobile phone terminal via the external extension terminal, and it is not necessary to store the driving power in the apparatus. There are also benefits.

  FIG. 1C shows another embodiment, which does not have a microphone and earphone, and connects the device main body (1) to an external extension terminal mounted on a mobile phone terminal via a connection terminal (2b). It is. For this reason, the voice of the other party during the call is emitted from the speaker of the mobile phone terminal, and the own voice is collected by the microphone of the mobile phone terminal. The method for synthesizing the desired BGM / sound effect sound is the same as that of the above-mentioned embodiment, and after setting the selection dial (3) to the desired BGM number, pressing the play button (5) Sounds such as desired BGM and sound effects are synthesized with your own voice and sent to the other party. In this embodiment, although not shown, since the voice of the sender is collected by the microphone of the mobile phone terminal, this apparatus acquires the collected voice from the external extension terminal before transmission. However, a process for synthesizing sound data and transmitting it to the terminal is required.
