Detailed description of the invention

Hereinafter, with reference to the accompanying drawings will be described a preferred embodiment according to the present invention.

FIG. 1 is a configuration diagram schematically illustrating a case in which a sound effect is stored in a mobile phone as an embodiment of the apparatus for providing a sound effect during a call according to the present invention. The apparatus for providing a sound effect during a call according to the present invention is additionally or integrally installed in a general mobile communication terminal 100, and has a digital signal processing (DSP) chip 110 that is responsible for reproducing voice calls and sound effects, Flash ROM (ROM) 130 for storing sound data for sound effects, a keypad 150 for a user to select to generate sound effects, and sound data for sound effects stored in the flash ROM 130 to the DSP chip. The controller chip 120 transmits and reproduces the effect sound.

The DSP chip 110, the flash ROM 130, and the controller chip 120 are already provided in a conventional mobile phone, and the keypad 150 may also use a mobile phone as it is. In the flash ROM 130, the controller 120 transmits the sound effect stored in the flash ROM 130 to the DSP chip 110 according to the selection of the keypad 150. And other user interface programs. The interface program may include a program for operating the controller 120 in response to the effect sound generation through the keypad and the selection of the effect sound type, and a program for downloading the effect sound from a separate specific server. The process of downloading the sound effect is substantially the same as the ringtone download process currently in service. For example, when a call is made to a specific server, the announcement is provided from the server. Accordingly, the user selectively downloads the desired sound effect. The flash ROM 130 is stored in the flash ROM 130. Other matters related to normal voice signal transmission, such as RAM, are obvious to those skilled in the art and will be omitted.

If the user wants to deliver the sound effect to the other party during the call, the user presses a predetermined keypad 150, and in response, the controller 120 transmits the sound data of the sound effect stored in the flash ROM 130 to the DSP chip. In step 110, the DSP chip 110 transmits the effect sound to the counterpart. The detailed method will be described in detail with reference to FIG. 3 below.

2 is a configuration diagram schematically illustrating a case in which a sound effect is stored in a separate service server as an embodiment of the apparatus for providing a sound effect during a call according to the present invention. The apparatus for providing a sound effect during a call according to the present invention may be implemented through a separate service server 300 connected to the switch via a switch 200 connecting a user and a counterpart. That is, the system for providing a sound effect during a call according to an embodiment of the present invention includes an effect sound selection signal that decodes a voice signal and a DTMF signal transmitted from a user, a counterpart, and a mobile phone of the user who wants to use the busy effect sound. Exchanger 200 for transmitting the voice signal mixed with the sound effect transmitted from the service server 300 to the mobile phone of the other party, and storing sound data about the sound effect in a separate database, It is composed of a service server 300 for mixing the sound data and the voice signal transmitted from the exchange 200 to transmit to the exchange. The service server 300 mixes sound data corresponding to the effect sound selection signal transmitted from the switch 200 to the sound signal. Techniques for mixing sound data for sound effects and user's voice signals are well known enough to those skilled in the art that there will be no explanation.

The switch 200 automatically connects a signal transmitted from the user's mobile phone to the service server 300 when the user calls a predetermined specific phone number, or the user's mobile phone number, that is, the caller ID. (caller id) to check whether the user can receive the sound effect providing service from the service server 300 to connect to the service server. When connecting through the process of checking the caller ID, it is necessary for the exchange 200 to secure a database for a legitimate user in advance. Preferably, when the user selects a specific keypad during a call and a DTMF signal corresponding to the keypad is input to the switch 200, the signal transmitted from the mobile phone of the user thereafter is changed to the switch 200. Alternatively, the service server 300 may transfer the service to the service server 300.

3 is a flowchart schematically illustrating a process of transmitting an effect sound to a counterpart through a mobile phone according to the present invention. In the case of the system providing the sound effect through the service server 300, as the service server 300 includes a processor having a sufficient performance, the sound of the user's voice data and the sound effect stored in the server as described above. The data may be appropriately mixed as necessary to transmit the voice and the effect sound simultaneously or only the effect sound to the counterpart through the switch 200.

However, since the processor of the mobile phone terminal cannot guarantee sufficient performance, a method of providing only sound effects instead of the user's voice is used. Specifically, it is as follows. In general, the user's voice input (S ₁₀ ) for the DSP chip 110 samples the voice and temporarily stores a certain period in the input buffer (S ₂₀ ). At this time, when the user presses the effect sound providing key pad (S ₃₀ ), the controller 120 retrieves sound data of the sound effect stored in the flash ROM 130 and replaces the voice section stored in the input buffer (S _40). ). In other words, the voice section is deleted and data for the sound effect is stored instead. In this case, the DSP chip 110 encodes the sound data for the effect sound (S ₅₀ ), stores the encoded data in an output buffer (S ₆₀ ) and transmits it to the mobile phone of the other party (S ₇₀ ). .

Alternatively, sound data for the sound effect may be stored in the output buffer. That is, the user's voice signal stored in the output buffer is replaced with sound data for the sound effect (S _{40 '} ) in response to the user's sound effect selection (S _30' ). In this case, the DSP chip 110 transmits a signal for the replaced effect sound to the counterpart (S ₇₀ ). However, when the voice is replaced by the output buffer, the flash ROM 130 needs to be encoded and stored in a form that can be transmitted through the mobile phone.

The present invention has the effect of providing an apparatus and a service capable of providing various sound effects during a call in order to appropriately express the emotion and intention of the speaker in accordance with the selection of the speaker in the voice communication through the mobile phone.

Simple modifications or changes of the present invention can be easily carried out by those skilled in the art, and all such modifications or changes can be seen to be included in the scope of the present invention.
