【Detailed ways】

Please refer to FIG. 1 , which shows a flow chart of a method for adjusting the playback sound of a mobile phone according to an embodiment of the present invention. This method includes the following steps. In step S120, the mobile device senses the volume of an ambient sound at its location. In step S140 , the mobile device correspondingly adjusts the volume of a playing sound played by the mobile device according to the volume of the ambient sound. Hereinafter, taking a mobile phone as an example, how the mobile phone executes the playing sound adjustment method according to the embodiment of the present invention is described in detail as follows.

Please refer to Figures 2 and 3 at the same time. FIG. 2 is a block diagram of a mobile phone 200 according to an embodiment of the invention. FIG. 3 is a flow chart of an example of the method for adjusting the playback sound executed by the mobile phone 200 of FIG. 2 . The mobile phone 200 includes a playback unit 210, an ambient sound sensing unit 220, a control unit 230, a judging unit 240, a volume adjustment button (not shown in FIG. 2 ), a setting interface 260, a timing unit 270, and a storage unit 280. The playing unit 210 is used for playing a playing sound Vo, and the playing sound Vo has a volume. The ambient sound sensing unit 220 is used for sensing the volume of the ambient sound Vi. The control unit 230 correspondingly adjusts the volume of the playing sound Vo of the playing unit 210 according to the volume of the ambient sound Vi.

The method for adjusting the playing sound performed by the mobile phone 200 is described below. In step S310, the judging unit 240 judges whether an automatic option of the setting interface 260 is activated. If the automatic option is not activated, it may indicate that the manual option is activated, so the mobile device 200 will enable the volume adjustment button, and the mobile phone 200 can adjust the volume of the playback volume sound Vo according to the actuation of the sound adjustment button, such as Shown in step S320. If the automatic option is activated, the mobile device 200 will enable the ambient sound sensing unit 220 and the control unit 230, and execute step S330.

In step S330, the judging unit 240 judges whether the playing unit 210 is playing. If the judging unit 240 judges that the playing unit 210 is playing, the mobile phone 200 will execute the two steps S340 and S350 of sensing the volume of the ambient sound Vi and adjusting the volume of the playing sound Vo.

In step S340, the ambient sound sensing unit 220 senses the volume of the ambient sound Vi. Next, the control unit 230 correspondingly adjusts the volume of the playing sound Vo of the playing unit 210 according to the volume of the ambient sound Vi, as shown in step S350 .

Further, step S350 may further include the following steps. In step S352, the judging unit 240 judges whether the volume of the ambient sound Vi exceeds a predetermined range. If the volume of the ambient sound Vi is greater than the maximum value of the predetermined range, step S354 is executed, and the control unit 230 increases the volume of the playing sound Vo of the playing unit 210 . If the volume of the ambient sound Vi is smaller than the minimum value of the predetermined range, step S356 is executed, and the control unit 230 reduces the volume of the playing sound Vo of the playing unit 210 . If the judging unit 240 judges that the volume of the ambient sound Vi does not exceed the predetermined range, go back to step S330.

Since the mobile phone 200 mentioned above can perform the two steps S340 and S350 of sensing the volume of the ambient sound Vi and adjusting the volume of the playing sound Vo when the playback unit 210 is playing. In this way, the mobile phone 200 can adjust the volume of the playing sound Vo to an appropriate volume when providing the playing sound Vo, for example, during a call or playing music. Furthermore, the mobile phone 200 can also end the method and the actions of each unit after the playback is stopped, and execute the sound adjustment method again when the playback is performed next time, so that the effect of power saving can be achieved.

Furthermore, when the judging unit 240 judges that the playing unit 210 is playing, it is also used to enable the timing unit 270 . The enabled timing unit 250 transmits an enable signal S to the ambient sound sensing unit 220 and the control unit 230 every predetermined time, so that the ambient sound sensing unit 220 periodically acquires the volume of the ambient sound Vi. In this way, every predetermined time, the mobile phone 200 will repeatedly perform the two steps S340 and S350 of sensing the volume of the ambient sound Vi and adjusting the volume of the playing sound Vo, so as to adjust the volume of the playing sound Vo of the mobile phone 200 in real time. Appropriate volume.

The following describes how the control unit 230 correspondingly adjusts the volume of the playing sound Vo of the playing unit 210 according to the volume of the ambient sound Vi by taking an example. Please refer to FIG. 4 , which shows a schematic diagram of an example of a lookup table LUT stored in the storage unit 280 of the mobile phone 200 according to an embodiment of the present invention. The storage unit 280 is used for storing the content of the LUT in FIG. 4 . This comparison table LUT has the corresponding relationship between the volume of the ambient sound Vi and the volume of the playback sound Vo, that is, the correspondence between various predetermined ranges of the volume of the ambient sound Vi and the multi-level volume of the playback sound Vo, such as the predetermined range d2-d3 Correspondence between decibels (dB) and the third-level volume "Level 3". In this way, when the control unit 230 is adjusting the volume of the playback sound Vo, the control unit 230 can query the corresponding relationship between the ambient sound Vi in the comparison table LUT and the volume of the playback sound Vo, so as to use the comparison table LUT and the volume of the ambient sound Vi, to adjust the volume of the playing sound Vo of the playing unit 210 accordingly.

For example, if the volume of the ambient sound Vi sensed by the ambient sound sensing unit 220 is dx decibels (dB), and the control unit 230 learns that the volume of the ambient sound Vi at this time is between d2˜d3 decibels according to the comparison table LUT When within the predetermined range, that is, d2<dx<d3, at this time, the control unit 230 will correspondingly adjust the volume of the playing sound Vo to be the third-level volume "Level3" that the mobile phone 200 can output, as shown in FIG. 4 .

Furthermore, it is assumed that the volume of the ambient sound Vi sensed by the ambient sound sensing unit 220 increases from dx decibels to dy decibels. At this time, if the judging unit 240 judges that the volume of the ambient sound Vi at this time has exceeded the predetermined range of d2-d3 decibels, and the volume of the environmental sound Vi (dy decibels) at this time is greater than the maximum value (d3 decibels) of the predetermined range. ), that is, d3<dy, then the control unit 230 will increase the volume of the playback sound Vo of the playback unit 210, for example, to the fourth-level volume “Level 4” that the mobile phone 200 can output, as shown in FIG. 4 . Similarly, if the judging unit 240 judges that the volume of the ambient sound Vi at this time has exceeded the predetermined range of d2 to d3 decibels, and the volume of the environmental sound Vi (dy decibels) at this time is smaller than the minimum value of the predetermined range (d2 decibels), that is, dy<d2, then the control unit 230 will correspondingly reduce the volume of the playback sound Vo of the playback unit 210, for example, to the second-level volume "Level 2" that the mobile phone 200 can output, as shown in FIG. 4 .

Please refer to FIG. 5 , which shows a schematic diagram of an example of a mobile phone 200 and its volume adjustment button 250 and setting interface 260 according to an embodiment of the present invention. In this example, the setting interface 260 includes a screen 261 and an operation key 262 . The setting interface 260 has an automatic option 260a and a manual option 260b, such as displayed on the screen 261 . The automatic option 260a will be determined by the mobile phone 200 as being activated, as shown in step S310 of FIG. 3 . If the automatic option 260a is activated, for example by the user using the operation key 262, it means that the mobile phone 200 can execute the above two steps S340 and S350 of sensing the volume of the ambient sound Vi and adjusting the volume of the playing sound Vo. If the manual option 260b is activated, it means that the mobile phone 200 can adjust the volume of the playing sound Vo according to the actuation of the sound adjustment button 250 , as shown in step S320 of FIG. 3 .

In the above example, the setting interface 260 uses the screen 261 as an interactive interface, and uses the operation keys 262 to perform software setting on the mobile phone 200 . However, it is not limited thereto, and the above-mentioned setting interface 260 can also be implemented in other ways. In the present invention, as long as the playback volume of the mobile phone 200 can be selectively adjusted manually or automatically through the setting interface 260, all are within the protection scope of the present invention.

In addition, please refer to FIGS. 6A and 6B , which respectively illustrate schematic views of an example of the front and back of the mobile phone 200 according to an embodiment of the present invention. As shown in FIG. 6A , the playback unit 210 (such as a speaker) of the mobile phone 200 is disposed on the upper side of the front of the mobile phone 200 . Furthermore, when the mobile phone 200 is in a call, for example, a radio unit 290 (such as: a microphone) is used to receive the volume of the user's conversation voice Vp during the call, and the radio unit 290 is arranged on the bottom of the front of the mobile phone 200. side. Therefore, in practice, the ambient sound sensing unit 220 can be disposed on the side of the mobile phone 200, as shown in FIG. 6A . Alternatively, the ambient sound sensing unit 220 can also be disposed on the back of the mobile phone 200, as shown in FIG. 6B. In this way, the ambient sound sensing unit 220 will be prevented from sensing the volume of the playback sound Vo provided by the playback unit 200 and the volume of the call sound Vp provided by the user to the sound receiving unit 290 during a call, However, the volume of the ambient sound Vi sensed by the ambient sound sensing unit 220 is affected. However, it is not limited to this. The ambient sound sensing unit 220 can also be disposed at other locations that can avoid interference from the playback sound Vo and the call sound Vp.

In the mobile phone and its sound adjustment method disclosed above in the present invention, the mobile phone can sense the volume of the ambient sound at its location, so as to adjust the volume of the sound played by the mobile phone accordingly according to the volume of the ambient sound. In this way, in a place where the volume of the ambient sound is high, the mobile phone can automatically increase the volume of the sound to avoid the volume being too low for the user to hear clearly. The phone can automatically reduce the volume of the playing sound, so as not to cause discomfort to the user due to too high volume.

In summary, although the present invention has been disclosed as above with a preferred embodiment, it is not intended to limit the present invention.
