Detailed ways

In order to make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only some, but not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

FIG. 1 shows a schematic flowchart of a method for adjusting a call sound according to an embodiment of the present invention. As shown in FIG. 1 , the method includes:

Step 120: When the mobile terminal is in a call state, determine the touch pattern formed by the touch points received on the touch screen of the mobile terminal.

The mobile terminal is in a call state, which may be the moment when the user answers the call through the mobile terminal, or the user is on a call.

When a user answers a call through a mobile terminal, he will put his ear close to the touch screen surface of the mobile terminal. At this time, the user's ear will be in contact with the touch screen of the mobile terminal. At the same time, the mobile terminal will receive these touch points, and according to these touch points The touch points form the corresponding touch graphics,

Step 140, when the touch pattern matches the pre-stored ear image, call the target audio parameter corresponding to the contact area where the touch pattern is located.

When a user answers a call, he/she just connects, but does not put his ear close to the touch screen of the mobile terminal. For example, if the user answers the call in a "hands-free" way, in this case, due to the loud voice of the external call, Usually no further volume adjustment is required. Therefore, the situation of this embodiment is that when the user puts his ear close to the touch screen of the mobile terminal, the call sound is adjusted. At this time, in this embodiment, the touch graphic can be matched with the pre-stored ear image. If the matching is successful, it means that the user has brought the ear close to the touch screen of the mobile terminal to make a call.

When the user's ear is close to the touch screen of the mobile terminal, the ear and the touch screen will form a contact area, and these contact areas are naturally the areas where the touch graphics are located.

In this embodiment, the mobile terminal can call the target audio parameter corresponding to the contact area where the touch graphic is located.

Step 160: Adjust the volume of the call sound output by the mobile terminal according to the target audio parameter.

The target audio parameter can adjust the volume of the call sound, so as to prevent the user from hearing too much or too little sound.

In this embodiment of the present invention, when the mobile terminal is in a call state, it collects touch points received on the touch screen and forms a touch pattern. When the touch pattern matches the pre-stored ear image, it means that the user is bringing his ear close to the touch screen. At this time, the target audio parameters corresponding to the contact area where the touch graphic is located can be called correspondingly, and the volume of the call sound can be adjusted according to the target audio parameters, so that when the user's ear is close to any area of the touch screen, You can hear clear calls.

FIG. 2 shows a schematic flowchart of a method for adjusting a call sound according to another embodiment of the present invention. As shown in FIG. 2 , step 120 includes:

Step 121, collecting touch points formed on the touch screen when the user's ear is in contact with the touch screen of the mobile terminal;

Step 122: Generate a corresponding touch graphic according to the touch point.

The current mobile terminal is usually a touch screen, and the touch screen includes a capacitive screen and the like. A full-screen mobile terminal usually adopts a capacitive screen. When the user's ear is close to the capacitive screen of the mobile terminal and contacts, all the contact points will cause the corresponding capacitance on the capacitive screen to change. According to the capacitance change of the touch point, all the touch points can be collected.

In this embodiment, the number of collected touch points may be relatively large, and corresponding touch graphics may be generated through these touch points. For example, these touch points can be modeled by some specific modeling models to generate corresponding touch graphics. The specific modeling solution is not described in detail in this embodiment. It should be pointed out in this embodiment that generating a touch graphic according to a touch point by any means is within the achievable scope of this embodiment.

When the user answers the phone, there is also a case where the ear is not brought close to the touch screen of the mobile terminal. For example, different situations such as answering a call in a "hands-free" manner. Therefore, in this embodiment, the corresponding touch graphic is accurately generated by the touch point, and it can be further judged whether the user puts the ear close to the touch screen of the mobile terminal to answer the call.

In this embodiment, ear images are pre-stored in the mobile terminal, and these ear images can form a standard library for judging whether the touch graphic is an ear image. When the touch pattern does not match the pre-stored ear image, it means that the user does not put the ear close to the touch screen of the mobile terminal to answer the call. At this time, it may be the collected finger touch pattern, etc. The audio parameter adjusts the volume of the call sound output by the mobile terminal. The preset audio parameters may be default values set by the operating system in the mobile terminal when answering a call.

FIG. 3 shows a schematic flowchart of a method for adjusting a call sound according to still another embodiment of the present invention. As shown in FIG. 3 , step 140 includes:

Step 141, acquiring the audio region divided by the touch screen according to the preset mode and the audio parameters corresponding to the audio region;

Step 142, determining the target audio area to which the contact area where the touch graphic is located belongs;

Step 143, calling corresponding target audio parameters according to the target audio region.

Wherein, when the mobile terminal can divide the touch screen into different audio regions in a preset manner, the touch screen of the mobile terminal can be regarded as a whole rectangular region, and then the rectangular region can be divided. This embodiment is not limited to a specific division manner, which does not affect the specific implementation of this embodiment. It should be pointed out that the size of the divided audio regions may be the same or different.

According to the divided audio regions, corresponding audio parameters can be matched for these audio regions. The size of the audio parameter determines the size of the sound output by the mobile terminal. And the larger the audio parameter is, the louder the sound output by the mobile terminal is; on the contrary, the smaller the audio parameter is, the smaller the sound output by the mobile terminal is.

In this embodiment, the size of the output power of the exciter in the mobile terminal can correspondingly adjust the size of the sound output by the mobile terminal. When the exciter is working, the output power of the exciter is transmitted outward with the center position of the exciter. At this time, the greater the distance between the corresponding area of the touch screen of the mobile terminal and the location of the exciter, the smaller the received power. Therefore, these areas require relatively large audio parameters to be set. Therefore, in this embodiment, when determining the audio parameters corresponding to the audio region, the distance between the center position of the audio region and the position of the exciter in the mobile terminal can be obtained, and the audio frequency corresponding to the audio region can be determined according to the size of the distance. parameter. Specifically, when the audio parameter corresponding to the audio region is determined according to the size of the distance, the audio parameter corresponding to the audio region can be correspondingly increased as the distance increases. In this way, even if the user's ear is close to the touch screen of the mobile terminal and the corresponding target audio area is far from the exciter, the user can hear the clear call sound due to the large audio parameter, avoiding unclear call sound.

FIG. 4 shows a schematic flowchart of a method for adjusting a call sound according to still another embodiment of the present invention. As shown in FIG. 4 , step 160 includes:

Step 161, correspondingly adjust the output power of the exciter according to the target audio parameter;

Step 162: Adjust the volume of the call sound according to the adjusted output power of the exciter.

In this embodiment, the mobile terminal can use the audio parameters to drive the exciter to work. For example, the output power of the exciter can be correspondingly increased through the audio parameters, and the call sound of the mobile terminal can be correspondingly increased, or the mobile terminal can also reduce the The output power of the small exciter reduces the call sound of the mobile terminal accordingly.

The audio parameter may be various parameters such as the size of the sound, the frequency response curve, the parallel parameter, and the degree of distortion. It should be noted that, in this embodiment, the mobile terminal correspondingly adjusts the output power of the exciter according to the target audio parameter, and after adjusting the volume of the call sound, the volume of the call sound is stabilized at a fixed value or around the fixed value. Specifically, no matter where the user's ear is close to any audio area of the touch screen of the mobile terminal, after adjusting the size of the sound by the audio parameters of the audio area, the user can hear the sound of a fixed size without causing the sound to follow As the user's ear moves on the touch screen of the mobile terminal, the sound heard by the user changes greatly, thereby providing the user with a better call state.
