The present invention relates to a portable terminal, and more particularly to a portable terminal capable of outputting a multi-button voice.

A portable terminal is a device capable of making a call or exchanging data while moving, for example, a mobile phone, a PDA (Personal Digital Assistant), or the like.

2. Description of the Related Art [0002] With the generalization of such portable terminals, various functions used in the portable terminal have been developed. Typical functions include outputting ring tones and button tones using various sound sources.

Portable handsets have come up to terminals that support 64 chords through 4 chord, 16 chord, and 40 chord in a single note. However, there is no portable terminal capable of simultaneously outputting a plurality of button tones. In the conventional portable terminal, when a signal for outputting another button sound is input before the completion of one button sound output, the button sound is outputted by terminating the button sound being output and outputting only the new button sound. That is, in the conventional button sound output method of the portable terminal, it is possible to output one button sound data of a plurality of chords (for example, 40 chords, 64 chords, etc.) There is no.

Accordingly, in the case where there is a high-speed button operation by the user, although a plurality of buttons are actually input to and processed in the portable terminal, there is a fear that only one button is input to the portable terminal and processed by the user. In particular, when a blind person inputs a plurality of buttons simultaneously and / or sequentially, it is impossible to audibly confirm whether or not an accurate input is made, so that information must be re-entered or a call connection or a message is created with incorrect information input . Also, when the subsequent button sound output starts before the completion of one button sound output, if the input of both buttons is performed at a high speed, there is a problem that the portable terminal processes only one button as if it is input.

In addition, there has been a problem that it is not possible to produce a musical effect such as a chord with a button sound of a portable terminal.

1 is a configuration diagram of a portable terminal according to a preferred embodiment of the present invention.

1, the portable terminal 100 includes a button unit 110, a control unit 120, a storage unit 130, a sound source processing unit 140, a sound source output unit 150, and a display unit 160 do. The sound source processing unit 140 may include a plurality of sound source processing units 140-1, 140-2, ..., 140-n (hereinafter collectively referred to as 140-n) and an accumulator 145. The sound source processing unit 140 is not divided into a plurality of sound source processing units 140-n in a hardware manner, but may be divided in software to process corresponding to a plurality of consecutive button operations. It is obvious that the number of divided sound source processing units 140-n can be determined in advance or can be determined flexibly by a control operation of the control unit 120. [ The portable terminal 100 may further include another high frequency processor, an antenna, and the like.

The button unit 110 includes a plurality of buttons, and various signals are input by the user's operation of the buttons, and the input unit 120 transmits the input signals. In particular, when there is a specific key input by a user's button operation, a signal for outputting a button sound corresponding to the key input (hereinafter referred to as a button sound output command) is transmitted to the control unit 120. The button unit 110 may be a number pad and / or a touch pad.

The control unit 120 modulates and modulates data such as voice, text, and images, and processes various signals in the portable terminal 100. In particular, upon receiving the button sound output command, the storage unit 130 is accessed to read the button sound data corresponding to the button sound output command of the stored button sound data. Also, one of the sound source processing units in an inactive state (for example, 140-1) is selected by determining whether the sound source processing unit 140-n is active and / or inactive. Also, the button sound data read from the storage unit 130 is transmitted to the selected sound source processing unit (for example, 140-1). If there is no sound source processing unit 140-n in an inactive state, a sound source processing unit (for example, 140-4) that terminates the earliest activity is selected and a signal for stopping button sound processing Quot; button sound processing stop command "). The controller 160 controls the display unit 160 to display data corresponding to the signal transmitted from the button unit 110 on the display unit 160.

If the button sound data is not generated and stored in the storage unit 130, the controller 120 may generate button sound data corresponding to the button sound data when the button sound output command is transmitted. In this case, a plurality of events (Event) for generating button sound data may be stored in the storage unit 130. [ Of course, since a plurality of events occupy a very small capacity, the additional storage unit in the control unit 120 may be provided separately and stored in the additional storage unit. Hereinafter, it is assumed that a plurality of events are stored in the storage unit 130 for convenience of explanation and explanation.

Most of the data used as button tones is composed of simple structures. Accordingly, when the button sound output command is transmitted, the control unit 120 accesses the storage unit 130 to read data on events necessary for the basic header, and combines the events to generate button sound data. For example, it is assumed that the data to be generated is data of the SMAF Phrase format. The SMAF Phrase format means a sound source format capable of outputting a plurality of sound sources at the same time. The data of the SMAF Phrase format is composed of a plurality of events. Accordingly, when receiving the button sound output command, the control unit 120 reads a plurality of events such as the size, output time, height, and end of the button sound in the storage unit 130 and generates the button sound data recorded in turn. The method of generating the data in the SMAF Phrase format is obvious to those skilled in the art, so that the detailed description is omitted here.

As an example of the generated button sound, if the instrument of the button sound is set to the piano according to the user's preset environment setting, and the size of the button sound is set to 4 steps of the total 5 steps, that is, 80% I suppose. When one of the plurality of buttons on the button unit 310 is pressed by the user's selection, the tone generator 370 generates' 80% of button sound, a piano sound, C sound for 600 ms, And generates button sound data composed of the same events. When another button among the plurality of buttons of the button unit 310 is pressed by the user's selection, the sound source data generator 370 generates a sound of 80 percent of a button sound, a piano sound, a D sound for 600 ms, &Quot;, " a ", and " a ". Here, the plurality of events are stored in the storage unit 130. Of course, it is obvious to those skilled in the art that the button tone data may be in a different sound source data format, such as a file in MIDI format in addition to data in the SMAF Phrase format. However, it should be a sound source format capable of outputting a plurality of sound sources at the same time.

The storage unit 130 is connected to the control unit 120 and stores various parameters for communication of the portable terminal 100. In particular, the button sound data corresponding to the button sound output command is stored. The button sound data can be stored in the number corresponding to the number of the plurality of buttons of the button unit 110 at least. For example, when the button of the button unit 110 is a numeric pad of '0 to 9', at least ten button sound data corresponding to each of the buttons 0 to 9 may be stored in the storage unit 130. In addition, when there are a plurality of types of instrument sounds (e.g., piano, organ, etc.) of button sounds, button sound data corresponding to each instrument can be stored as the number of the plurality of buttons of the button section 110. That is, if the instrument type of the button sound is two types of piano and organ, and the button of the button unit 110 is a numeral pad of '0 to 9', the button sound data corresponding to the piano corresponds to each button of 0 to 9 And the button tone data corresponding to the organ may be stored in the storage unit 130 by the number corresponding to each of the buttons 0 to 9. Of course, it is obvious that the button tone data stored corresponding to each button can be diversified according to the playing genre (for example, jazz, etc.).

Also, the button unit 110 may store the button sound data corresponding to the plurality of buttons in advance in the storage unit 130, and may store a plurality of events constituting the button sound data.

The sound source processing unit 140 processes various sound source data, such as decoding and mixing various transmitted sound source data, and transmits them to the sound source output unit 150. More specifically, the sound source processing unit 140 includes a plurality of sound source processing units 140-n and an accumulator 145. The sound source processing unit 140-n processes the sound source data such as decoding the button sound data read from the storage unit 130 by the control unit 120 and transmitted to the sound source processing unit 140-n, Mixes the sound source data processed by the plurality of sound source processing units 140-n and transmits them to the sound source output unit 150. [

The sound source output unit 150 converts various sound source data processed by the sound source processing unit 140 (for example, button sound data, etc.) into an analog signal and outputs the analog signal.

The display unit 160 displays various kinds of photographs, images, and text data read by the control unit 120 and stored in the storage unit 130 under the control of the control unit 120. [ In particular, when the user intends to set a preset environment for the button sound by button operation, it displays the button sound instrument type and / or button sound intensity.

2 is a flowchart illustrating a multi-button sound output method in a portable terminal according to a preferred embodiment of the present invention. Hereinafter, a multi-button sound output method in a portable terminal according to a preferred embodiment of the present invention will be described with reference to FIG.

In order to output the button sound, first, a preference setting for specifying the sound of the button sound (e.g., musical instrument type, performance genre, etc.) and size is performed by the user's selection (step 200). If there is no selection by the user for the dictionary environment setting, a preset environment is used.

In step 210, when there is a specific button operation of the button unit 110 of the user, a button sound output command for outputting a button sound corresponding to the button operation is transmitted to the control unit 120.

 In step 220, when the button sound output command is received, the control unit 120 determines whether all of the plurality of sound source processing units 140-n determined in advance or dynamically are active.

If all of the sound source processing units 140-n are active, the controller 120 first selects a sound source processing unit (for example, 140-4) to end the button sound data processing (step 230 ), A signal for stopping the processing of the button sound in process (hereinafter, referred to as a "button sound processing stop command") is transmitted (step 240).

If there is an inactive sound source processing unit (for example, 140-1, 140-2, 140-3) as a result of the determination in step 220, the controller 120 determines that one of these -1). If there are a plurality of sound source processing units 140-n in an inactive state, it is preferable to select them in a predetermined order.

In step 260, the control unit 120 accesses the storage unit 130 to read out the button sound data corresponding to the button sound output command and transmits it to the selected sound source processing unit (e.g., 140-1 or 140-4) . Of course, in addition to the method in which the control unit 120 transmits the read button sound data to the selected sound source processing unit 140-1 or 140-4, the sound source processing unit 140-1 or 140-4 selected by the control unit 120 and / / RTI > and / or may be provided with direct access to the storage 130, as would be apparent to those skilled in the art.

In addition, although FIG. 2 shows that the step 260 is performed after the step of determining and selecting the sound source processing unit 140 in the inactive state (i.e., steps 220 to 250) It is not essential, and the end of each step may vary depending on the implementation method. For example, step 260 may be performed before step 220 is performed.

In step 270, the sound source processing unit 140 processes the transmitted button sound data and transmits the processed button sound data to the sound source output unit 150. That is, the selected sound source processing unit 140-1 or 140-4 performs processing such as decoding of the received button sound data, and the accumulator 145 generates a plurality of sound source output units 140- And transmits the mixed data to the sound source output unit 150.

In step 280, the sound source output unit 150 analog-converts the transmitted button sound data and outputs the same. As described above, the data output to the sound source output unit 150 is data obtained by mixing the plurality of data processed by the sound source processing unit 140-n by the accumulator 145, so that even if a new button sound is output, It is possible not to stop the generation of the button sound being outputted to the user. This will be described with reference to Figs. 3A and 3B.

FIG. 3A is a diagram for continuously inputting button sound output in a conventional portable terminal, and FIG. 3B is a diagram for continuously inputting button sound output in a portable terminal according to another preferred embodiment of the present invention.

Referring to FIG. 3A, in the conventional portable terminal, when a new button sound output command is input before the end of the output of one button sound, the conventional button sound is forcibly terminated and a new button sound is output. That is, assuming that the output time of each button sound is 600 ms, if a button sound output command following the preceding button sound is output (for example, in a state of being output for 400 ms) is input, And outputs a succeeding button sound.

However, in the case of the present invention as shown in FIG. 3B, even if a new button sound output command is inputted before one output ends, the button sound data that has been outputting previously can be output at a predetermined output time (for example, 600 ms ), The output of the new button sound data is started for a predetermined output time separately from the point of time when the new button sound output command is input. Therefore, a plurality of button tone data are mixed and output in a certain area (i.e., the hatched area in FIG. 3B). Therefore, even if a new button sound is output, it is possible not to stop the generation of the button sound currently being output.

4 is a flowchart illustrating a multi-button sound output method in a portable terminal according to another embodiment of the present invention.

Referring to FIG. 4, a multi-button sound output method in a portable terminal according to another preferred embodiment of the present invention will be described. The basic method is similar to the method described above with reference to Fig. However, in the above-described method, the button sound data is generated in advance and stored in the storage unit 130. However, in this method, when the button sound output command by the button operation of the user button unit 310 is input, 120 generates button sound data. Therefore, the description will be made focusing on the differences therebetween.

Steps 400 to 450 are the same as or similar to steps 200 to 250 described above. Therefore, detailed description is omitted (see steps 200 to 250 described above).

In step 460, the control unit 320 generates button sound data by combining a plurality of events such as the size, the output time, the height, and the end of the button sound. The process of generating button tone data is as described above. The plurality of events are stored in the storage unit 130. Of course, as described above, even if a plurality of events are not stored in the storage unit 130 but stored in another storage unit in the controller 120, the present invention can be applied to the same or similar events. Here, the step 460 of generating the button sound data is performed by selecting one sound source processing unit (for example, 140-1) by determining the presence or absence of the sound source processing unit 140-n in the inactive state Step 420 to step 450) have been performed, it will be obvious to those skilled in the art that the order of these steps is not necessarily essential. That is, step 460 may be performed before step 420 is performed.

In step 470, the button sound data generated by the control unit 120 is transmitted to a selected sound source processing unit (for example, 140-1) of the plurality of sound source processing apparatuses 140-n and processed. That is, the selected sound source processing unit 140-1 performs processing such as decoding the received button sound data, and the accumulator 145 performs processing such as decoding of the button sound data received from the plurality of sound source output devices (i.e., the remaining sound source output devices except 140-1) And transmits the processed data to the sound source output unit 150 by mixing them. Of course, the sound source processing unit 140-1 selected by the controller 120 in addition to the method of transmitting the button sound data generated by the controller 120 to the sound source processing unit (for example, 140-1) It is obvious to those skilled in the art that it is possible to directly access and process the data.

In step 480, the processed button sound data is transmitted to the sound source output unit 160 and output to the outside. In this case, since the data output to the sound source output unit 150 is data obtained by mixing the plurality of data processed by the sound source output apparatus 140-n by the accumulator 145, even if a new button sound is output, It is possible not to stop the generation of the button sound.

As described above, the multi-button sound output method in the portable terminal and the portable terminal according to the present invention can output independent multi-channel sound sources at the same time without interrupting the existing output sound when the button sound is outputted from the portable terminal .

In addition, the present invention also has the effect of confirming whether or not an auditory input is correctly performed even when a user, particularly a blind person, operates two buttons simultaneously and / or continuously in the portable terminal.

In addition, the present invention also has an effect of producing a chord effect by using a button tone of a portable terminal.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention as defined in the appended claims. It will be understood that the invention may be varied and varied without departing from the scope of the invention.
