[0097] Embodiments of the present application

[0098] The exemplary embodiments will be described in detail herein below with reference to the drawings. When the following description refers to the drawings, identical numbers on different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of apparatuses and methods consistent with some aspects of the present application as detailed in the appended claims.

[0099] It should be noted that, as used in this document, the terms "include," "includes," "including," "has," "have," "having," or the like, are used in the sense of "including" and not by way of rinse, such that a process, method, article, or apparatus that includes items does not include only those items but can include other items not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element preceded by "comprises a... " does not, without more limitations, foreclose the existence of additional identical elements in the process, method, article, or apparatus that includes the element. Components, features, and / or elements with the same name or reference number can have the same or different meanings and / or functions in different embodiments.

[0100] It should be understood that, although the terms first, second, third, etc. can be used herein to describe various information, these terms are not intended to denote a particular order or hierarchy. These terms are used only to distinguish one category of information from another. For example, without departing from the scope hereof, first information can be referred to as second information, and similarly, second information can be referred to as first information. Depending on the context, the word "if' as used herein can be interpreted to mean "when" or "in response to determining" or "in response to a determination." Also, as used herein, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms "comprises," "comprising," "includes," and / or "including," as used herein, specify the presence of stated features, steps, operations, elements, components, items, categories, and / or groups but do not preclude the presence or addition of one or more other features, steps, operations, elements, components, items, categories, and / or groups thereof. As used herein, the term "or," "and / or," "at least one of," and the like as used herein are to be interpreted as inclusive or meaning any one or any combination. For example, "A, B or C" or "A, B, and / or C" means "any of the following: A; B; C; A and B; A and C; B and C; A, B and C." Only terms clearly indicated to the contrary will exclude the presence of other elements or matter. For example, the phrase "comprising A or B" will be understood to include the presence of A alone or B alone, in addition to the presence of both A and B.

[0101] It should be understood that, although each step in the flowchart in the embodiments of the present application is shown in sequence according to the arrow, these steps are not necessarily executed in sequence according to the arrow. Unless otherwise specified herein, the execution of these steps is not strictly limited in sequence, and they can be executed in other sequences. Moreover, at least part of the steps in the figure can include multiple sub-steps or multiple stages, which are not necessarily executed at the same time, but can be executed at different times, and the execution sequence is not necessarily sequential, but can be alternately executed with at least part of other steps or sub-steps or stages of other steps.

[0102] Depending on the context, the word "if" as used herein can be interpreted as meaning "when" or "while" or "in response to determining" or "in response to detecting". Similarly, depending on the context, the phrase "if it is determined" or "if (a stated condition or event) is detected" can be interpreted as meaning "when it is determined" or "in response to determining" or "when (a stated condition or event) is detected" or "in response to detecting (a stated condition or event)".

[0103] It should be noted that, in this document, step codes such as S1, S2, etc. are used for the purpose of more clearly and briefly expressing the corresponding content, and do not constitute a substantial limitation in sequence. Those skilled in the art may, in specific implementation, perform S2 before performing S1, etc., but these should be within the scope of protection of the present application.

[0104] It should be understood that the specific embodiments described herein are merely intended to explain the present application, and are not intended to limit the present application.

[0105] In the following description, the suffixes such as "module", "part", or "unit" used for an element are merely intended for facilitating explanation of the present application, and have no specific meaning by themselves. Thus, "module", "part", or "unit" can be mixedly used.

[0106] The communication device in the present application can be a terminal device (such as a mobile phone) or a network device (such as a base station), and the specific meaning needs to be clarified according to the context.

[0113] The audio output unit 103 can convert audio data, which is received by the radio frequency unit 101 or the WiFi module 102 or stored in the memory 109, into an audio signal and output the audio signal as sound when the mobile terminal 100 is in a call signal reception mode, a call mode, a recording mode, a voice recognition mode, a broadcast reception mode, and / or the like. In addition, the audio output unit 103 can provide audio output related to a particular function performed by the mobile terminal 100 (e.g., a call signal reception sound, a message reception sound, and / or the like). The audio output unit 103 can include a speaker, a buzzer, and / or the like.

[0114] The A / V input unit 104 is configured to receive audio or video signals. The A / V input unit 104 can include a graphics processor (GPU) 1041 and a microphone 1042.

Processed image frames can be displayed on the display unit 106. Processed image frames can be stored in the memory 109 (or other storage medium) or transmitted via the radio frequency unit 101 or the WiFi module 102. The microphone 1042 can receive sound (audio data) via the microphone 1042 in a telephone call mode, a recording mode, a voice recognition mode, or the like, and can process such sound into audio data. Processed audio (voice) data can be converted into a format that can be transmitted to a mobile communication base station via the radio frequency unit 101 in the case of the telephone call mode. The microphone 1042 can implement various types of noise cancellation (or suppression) algorithms to cancel (or suppress) noise or interference generated in the process of receiving and transmitting audio signals.

The touch panel 1071 can include two parts, a touch detecting device and a touch controller. The touch detecting device detects a user's touch position and detects a signal resulting from a touch operation, and transmits the signal to the touch controller; the touch controller receives touch information from the touch detecting device and converts it into touch coordinates, which are then transmitted to the processor 110, and can receive commands from the processor 110 and execute them.

Although in FIG. 1 the touch panel 1071 and the display panel 1061 are implemented as two separate components to achieve the input and output functions of the mobile terminal, in some embodiments, the touch panel 1071 and the display panel 1061 can be integrated to achieve the input and output functions of the mobile terminal, without limitation.
