Description

  The present invention relates to a mobile phone terminal, a volume control method, a program, and a recording medium, and more particularly, to a mobile phone terminal that adjusts transmission / reception volume, a volume control method, a program, and a recording medium.

  In recent years, since mobile phones have become widespread and base stations have increased, it is possible to make calls using mobile phones in various places.

  However, in an environment of urban noise, etc., if you do not talk by adjusting the call volume (transmission / reception volume), it is difficult to hear the reception volume due to the surrounding noise, or if the reception volume is not lowered in quiet places It became a cause.

In view of this, several techniques for adjusting the volume have been proposed, such as adjusting the transmission / reception volume and a device for preventing sound leakage from the earphone when using the audio play function of the mobile phone (Patent Documents 1 to 3). 4).

  However, the technology as described above has a problem that the received sound volume adjustment is a level adjustment on a UI (User Interface), and the operation is troublesome. In addition, the transmission volume is often determined by a fixed value, and there is a problem that ambient noise is not taken into consideration. Also, depending on the surrounding noise, it is often difficult to hear the incoming call sound. On the contrary, in a quiet environment, sound leaks and the surrounding people may hear the content of the call. Moreover, the ambient sound may be excessively picked up as the transmission volume, which has been a problem in enjoying a comfortable call.

  The present invention has been made in view of such a situation, and an object thereof is to optimally control the transmission / reception volume of a mobile phone terminal according to the ambient sound pressure.

  A first mobile phone terminal according to the present invention is a mobile phone terminal having a volume control means capable of adjusting a reception volume level and a transmission volume level, and a call state is started at the mobile phone terminal. A sound detection means for detecting ambient sound pressure, wherein the sound volume control means adjusts the reception sound volume level, the transmission sound volume level, and controls equalization according to the detected sound pressure. Features.

  A first volume control method according to the present invention is a volume adjustment method for a mobile phone terminal having volume control means capable of adjusting a reception volume level and a transmission volume level when a call state is started. And a step of detecting ambient sound pressure, and a step of adjusting the received sound volume level, the transmitted sound volume level and controlling equalization in accordance with the detected sound pressure.

  A first volume control program according to the present invention is a volume control program for a mobile phone terminal having volume control means capable of adjusting a reception volume level and a transmission volume level, and a call state is started. In addition, a computer is caused to execute processing for detecting ambient sound pressure and processing for adjusting a reception sound volume level, a transmission sound volume level and controlling equalization according to the detected sound pressure. .

  The first recording medium according to the present invention is a computer-readable recording medium for recording the processing of the first volume control program of the present invention.

  According to the present invention, the transmission / reception volume of the mobile phone terminal can be optimally controlled according to the ambient sound pressure.

  Embodiments of the present invention will be described below in detail with reference to the drawings. The embodiments described below are preferred embodiments of the present invention, and thus various technically preferable limitations are given. However, the scope of the present invention is particularly limited in the following description. As long as there is no description of the effect, it is not restricted to these aspects.

  The present invention is characterized in that it has a function of grasping and judging a surrounding situation with respect to a reception volume / transmission volume of a mobile phone and can always make a call at an optimum level.

  FIG. 1 is a block diagram of a mobile phone according to an embodiment of the present invention. Sound detection unit 1 for detecting ambient sounds, antenna unit 2, radio unit 3, key input unit 4, RTC (Real Time Clock) unit 5, CPU (Central Processing Unit) 6, memory 7, display control unit 8, display Part 9, receiver control part 10, receiver 11, microphone control part 12, and microphone 13.

  In particular, the present invention includes a sound detection unit 1 and has a function of changing a transmission / reception level after estimating and judging a surrounding situation.

  Next, the operation process of this embodiment will be described.

  When the CPU 6 recognizes that the call state has been entered, the sound detection unit 1 detects the surrounding noise situation at that time.

  FIG. 2 is a diagram for explaining the relationship between the ambient sound pressure detected by the sound detector 1 and the operation mode. As the ambient sound pressure changes from quiet to noisy, the operation mode changes to Mode A, Mode B, and Mode C.

  FIG. 3 is a diagram for explaining the relationship between the ambient sound pressure detected by the sound detection unit 1 and the frequency. Mode L is used when there is a peak in the bass, and Mode M when there is a peak in the mid-high.

  The transmission volume level, reception volume level, and equalizing characteristic are determined by a combination of the modes shown in the above figures. Details are as shown in Table 1 below.

  For example, in a quiet environment (Mode A), the received sound volume level is set to a low value to prevent sound leakage, and the transmitted sound volume level is increased to deal with a quiet call. f Special equalizing is not applied and flat. When noise of a certain level or more is detected, f-specific equalization is performed according to the frequency of the noise to improve the intelligibility in transmission / reception.

  In a noisy environment (Mode C), the received sound volume level is increased and the transmitted sound volume level is suppressed.

  As described above, the CPU 6 performs reference, determination, and control of each figure and table, and transmits the result to the receiver control unit 10 and the microphone control unit 12 to appropriately control the receiver 11 and the microphone 13, respectively.

  As described above, the mobile phone terminal according to the present embodiment can provide a comfortable call in any environment by automatically changing the transmission / reception level according to the surrounding environmental conditions.

  Further, the sound detection unit 1 may not be provided, and a call microphone may have the same function as the sound detection unit 1.

  Also, by adjusting the volume level at regular intervals, it is possible to cope with environmental changes during a call.

  The processing by the CPU for executing the present invention constitutes a program according to the present invention. As a recording medium for recording the program, a semiconductor storage unit, an optical and / or magnetic storage unit, or the like can be used. By using such a program and a recording medium in a system having a configuration different from that of each of the above-described embodiments and causing the CPU to execute the program, substantially the same effect as the present invention can be obtained.

  Although the present invention has been specifically described above based on the preferred embodiments, it is needless to say that the present invention is not limited to the above-described ones and can be variously modified without departing from the gist thereof.
