In this embodiment, a terminal is provided. As shown in FIG. 4, the method includes: a plurality of speakers 40, a sensor 42 disposed to sense a display manner of the terminal; and a processor 44 connected to the sensor 42 and configured to be The display mode generates a switching signal; the electronic switch 46 is connected to the processor 44, and is configured to select a designated speaker from the plurality of speakers to perform sound external release according to the switching signal, wherein the current external release effect of the designated speaker is excellent The current external release effect of the speaker that is not selected. In a preferred embodiment of the present embodiment, the sensor 42 may include, but is not limited to, a gravity sensor (or an acceleration sensor). In order to better understand the above embodiments, the following detailed description will be given in conjunction with the preferred embodiments. The main design idea of this embodiment is that the gravity sensor can simultaneously read the values of the three dimensions (x, y, z), and the terminal can be conveniently determined. Then the terminal can judge the terminal according to the gravity sensor. The position (that is, the way the terminal is placed), and then select the most suitable speaker to work, so that the terminal can ensure that the volume is normal and the sound quality is normal regardless of the position. As shown in FIG. 11, the principle of this embodiment is as follows: The terminal includes a processor 44, a plurality of speakers 40, an electronic switch 46 and a gravity sensor 42. Among them, the gravity sensor 42 of the terminal is placed in the sensing terminal. There are several basic placement methods, such as horizontally facing up, horizontally facing down, vertical placement, etc., which will be described in detail below. Narration. It can record the values of the three directions (x, y, z) in real time, so that it can be prepared to judge the current placement of the terminal. The processor 44 receives the data of the gravity sensor 42, determines the terminal placement mode, and then looks up the table, matches the position of the speaker 40 of the terminal itself, finds the most suitable speaker 40, and then switches to the electronic switch. The control command is issued; the processor here can directly use the processor of the terminal itself, and of course, other processors can also be used. Select the speaker corresponding to this placement method; send the command to the electronic switch to execute. The electronic switch 46 connects the corresponding speaker path according to the command to make it work. Electronic switch: The electronic switch can select one of the speaker channels according to the instruction of the controller. Correspondingly, if it is not selected, it will be closed by default; it accepts the command of the controller and executes the command. Speaker (or speaker) Speaker 40: In this embodiment, the terminal has two speakers, speaker@located on the back and speaker2 at the bottom of the terminal. Its main function is to perform audio sound release. In this embodiment, the opening of the speaker 40 (for example, the speaker above or below the figure) is specified, which is controlled by the controller. The multi-speaker terminal of this embodiment has two or more speakers. For convenience of explanation, a terminal having two speakers will be described as an example. In the following embodiments, it is assumed that two speakers are respectively located at the back of the terminal and the lower portion of the terminal when placed vertically. As shown in Figure 5-10, there are 6 types of terminal basic placement methods of the present invention, and other placements can also be classified into one of the 6 modes; the basic placement position: the terminal has six basic planes, and the six reference planes are Benchmarks, there are six basic placement methods, as shown in the six figures in Figure 5-10. Of course, there are still more placement methods between the six placement methods, and these intermediate states can be classified into one of six, and therefore will not be separately described. The six basic placement methods are explained separately: Basic placement method 1: The terminal is placed vertically. At this time, the gravity sensor data should be (*, +g, *), where the Y axis is the value of gravity acceleration (g), X The data of the z-axis and the z-axis are data of about 0 (the case of the completely vertical is 0, but in reality, it is a value that swings around 0). Therefore, as long as it is judged that the value of the Y-axis is g, it can be determined that the current placement mode of the terminal is as shown in FIG. 5. Basic placement 2: The terminal is placed vertically and then rotated 180° C, ie vertically inverted. At this time, the gravity sensor data should be (*, -g, *), where the Y axis is a negative value of gravity acceleration (-g), and the data of the X and z axes is about 0 (the case of a completely vertical is 0, But in reality it will be a value that swings around 0). Therefore, as long as it is judged that the value of the Y-axis is -g, it can be determined that the current placement mode of the terminal is as shown in FIG. 6. Basic placement mode 3: The terminal is placed horizontally and the screen is facing up. This is also a very common way for the terminal. If the speaker of the terminal is just at the back of the terminal, the sound quality pit will be greatly affected. At this time, the gravity sensor data should be (+g, *, *), where the X axis is the value of gravity acceleration (+g), the number of y and z axes According to the data of 0 or so (the case of completely vertical is 0, but in reality it will be a value that swings around 0). Therefore, as long as it is judged that the value of the X-axis is +g, it can be determined that the current placement mode of the terminal is as shown in FIG. Basic placement method 4: The terminal is placed horizontally with the screen facing down, which is also a very common way for terminals. At this time, the gravity sensor data should be (-g, *, *), where the X axis is the value of gravity acceleration (-g), and the data of the y and z axes is about 0 (the case of complete vertical is 0, but In practice, it will be a value that swings around 0). Therefore, as long as it is judged that the value of the X-axis is -g, it can be determined that the current placement mode of the terminal is as shown in FIG. Basic placement mode 5: The terminal is placed vertically on the side and rotated 90° on the vertical basis. The data of the gravity sensor should be (*, *, +g), where the Z axis is the value of gravity acceleration (+g). The data of the X and y axes is about 0 (the case of a completely vertical is 0, but in reality it will be a value that swings around 0). Therefore, as long as it is judged that the value of the Z axis is +g, it can be determined that the current placement mode of the terminal is as shown in FIG. Basic placement mode 6: The terminal is placed vertically on the side and rotated 90° on the vertical basis. The data of the gravity sensor should be (*, *, -g), where the Z axis is the value of gravity acceleration (-g). The data of the X and y axes is about 0 (the case of a completely vertical is 0, but in reality it will be a value that swings around 0). Therefore, as long as it is judged that the value of the Z axis is -g, it can be determined that the current placement mode of the terminal is as shown in FIG. Gravity sensor and basic placement position: The value of the gravity sensor can be used to judge the current basic position of the terminal very easily. Once the terminal position of the terminal is designed, it is also determined, so each base can be placed in a certain position. The speaker is bound and solidified in the terminal program in the form of a list. As shown in FIG. 12, the flow of the sound release method based on the terminal speaker is as follows: Step S1202: The system is initialized, and the system associates each basic placement mode of the terminal with a certain speaker. These correspondences can be queried by the program. For basic placement methods 1 and 2, since the terminal is placed vertically, the speaker2 at the bottom is occluded, so we have to choose speaker!, that is, the basic placement methods 1 and 2 correspond to speakei. In the same way, the correspondence between other basic placement methods and the speaker can be judged; since the speaker position of each terminal is different, this initialization needs to be performed according to each terminal, and a user interface can be specifically designed, and the user himself can perform according to the situation of the terminal. Configure, configure the speaker corresponding to each basic placement mode. Since there are six basic placement methods, and the speaker may be only two or three, there will be multiple cases where the basic placement method corresponds to the same speaker. Step S1204: The gravity sensor is opened by default in the same case. It can be recorded without special processing. It automatically records the acceleration values of the three directions (x, y, z). In order to ensure that the gravity sensor is valid, during program initialization, The gravity sensor will be calibrated and read. If there is a problem with the gravity sensor, a prompt will be given on the UI interface to notify the user in time. Step S1206: The processor reads the value of the (x, y, z) of the gravity sensor in real time, and judges the placement manner of the terminal according to the values, such as x=+g (g is the acceleration under the gravity of the earth, about 9.8 m/ S2), it can be judged that the terminal is placed horizontally at this time, and the screen is facing upward, that is, the basic placement mode in FIG. 7, and speaker2 should be selected to work. If x=-g (g is the acceleration under the gravity of the earth, about 9.8m/s2), it can be judged that the terminal is placed horizontally at this time, and the screen is facing down, that is, the basic placement mode in Fig. 8, then select speaker ! To work, select speaker2 at this time. If y=+g (g is the acceleration under the gravity of the earth, about 9.8m/s2), it can be judged that the terminal is vertically placed at this time, and it is the positive sequence, that is, the basic placement mode in Fig. 5, and the speaker should be selected at this time. !working. If =-9 is the acceleration under the gravity of the Earth, about 9.8m/s2), it can be judged that the terminal is placed horizontally at this time, and the screen is facing down, that is, the basic placement mode in Figure 6, at this time, select speakei to work, At this point, you can choose speaker2. For example, if z=+g (g is the acceleration under the gravity of the earth, about 9.8m/s2), it can be judged that the terminal is vertically placed at this time, and it is the positive sequence, that is, the basic placement mode in Fig. 9. At this time, you should select speakei. working. For example, if 2=-9 ( ₉ is the acceleration under the gravity of the earth, about 9.8m/s2), it can be judged that the terminal is placed horizontally at this time, and the screen is facing down, that is, the basic placement mode in Fig. 10, and then select speakei. Step S1208: It is determined whether the basic placement mode of the terminal is consistent with the basic placement mode currently detected. If they are consistent, no change is needed, and the process branches to S1206. If not, step S1210 is performed; Step S1210: Processor query The speaker corresponding to the current basic placement mode, this list of queries, has been given in step S1202. Once the query is complete, you know which speaker you should use. The processor then sends an instruction to the electronic switch; Step S1212: The electronic switch receives the command and turns on the specified speaker. The specified speaker will work, and the speaker that is not specified will not work. Upon completion, the process jumps to step S1206 to continue the loop. Until the program stops or the terminal is shut down. The above steps are all automatically executed by the program without manual intervention. But you can also add a manual intervention option based on this. This can be set in the program, the user can select the speaker he wants to use, and the system will let the speaker work. However, there are a few points to be explained: a) The priority of the manual setting is higher than the priority of the automatic judgment of the program, that is, as long as the user selects a specific speaker, the terminal uses the speaker for external release; b) the general situation Next, it is recommended to use the program to automatically judge the main, the program is more flexible, the feedback is more sensitive, can make up for the problem of slow manual operation, and can provide higher sound quality and volume for the largest program. In summary, the embodiments of the present invention achieve the following beneficial effects: Compared with the current speaker technology, the following advantages are achieved: No matter how the terminal is placed, a suitable speaker can be selected to ensure volume and sound quality; only one electronic component is added to the hardware. Switch (when the terminal has a speaker, one or more need to be added), other can borrow the existing configuration of the terminal (such as the gravity sensor configured by the terminal itself), which is simple and convenient; only one speaker works at a time, ensuring that multiple speakers are not Will interfere with each other, resulting in a decline in sound quality; the entire process is automatically executed by the program, the entire process of data reading, program judgment and execution are automatically executed according to the script, without manual participation, reliable and practical.
