When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of devices consistent with certain aspects of the present disclosure, as detailed in the appended claims.
In the description of the present disclosure, it is to be understood that the terms "upper", "lower", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in fig. 1.
The embodiment of the present disclosure provides an audio module, including:
a first audio component 140 having a speaker mode of operation as a speaker and an earpiece mode of operation as an earpiece; wherein, the output power of the first audio component 140 in the speaker operating mode is greater than the output power of the first audio component 140 in the earpiece operating mode;
a sound outlet hole for outputting the sound outputted from the first audio module 140 to the outside;
the first sound cavity 112 is respectively connected to the first audio module 140 and the sound outlet.
In the embodiment of the present disclosure, the first audio component 140 refers to a transducer device for converting an electrical signal into an audio signal, wherein the electrical signal may be a communication electrical signal or a multimedia electrical signal, and the communication electrical signal may be a voice call electrical signal completed in a voice call procedure; the multimedia electrical signal may be an electrical signal generated during playing of the streaming media file.
The first audio component 140 may be a magnet that generates a driving force under the action of a magnetic field to make the diaphragm vibrate to generate sound, or a piezoelectric material that generates a piezoelectric effect under the action of an electric field to make the diaphragm vibrate to generate sound.
The first audio component 140 includes, but is not limited to, an electrodynamic audio component, an electromagnetic audio component, or a piezoelectric audio component.
Taking the electromagnetic audio component as an example, the first audio component 140 includes a housing and a sound generating device located in the housing, where the sound generating device includes an electromagnet, a vibrating element and a diaphragm, and after the electromagnet is powered on, the electromagnet and the vibrating element attract or repel each other and generate a driving force in the process of attracting or repelling each other, and the driving force further drives the diaphragm to vibrate and generate sound. The adjustment of the output power of the first audio module 140 can be realized by a driving circuit, specifically, the driving circuit is electrically connected to the electromagnet, the driving circuit increases the current passing through the first audio module 140, and the output power of the first audio module 140 increases. The drive circuit reduces the current through the first audio component 140 and the power output by the first audio component 140 is reduced. That is, the magnitude of the output power of the first audio component 140 may be achieved by varying the magnitude of the current of the audio signal through the first audio component 140.
The first sound cavity 112 may serve as a front sound cavity of the first audio component 140, and the first sound cavity 112 has a sound amplifying function by resonating with a diaphragm of the first audio component 140. The sound outputted from the first audio module 140 passes through the first sound cavity 112 and is transmitted out through the sound outlet, and finally is heard by the user.
In contrast, the output power of the first audio component 140 in the working mode of the handset is relatively low, and the volume of the sound heard by the user is also relatively low, for example, the volume of the sound is 60 db or not more than 80 db at most, at this time, the ear of the user can be close to the sound outlet hole to make a call or voice, and the working mode of the handset effectively ensures the privacy of the call. The earphone working mode is suitable for scenes with low sound volume needing to be output, for example, scenes in which the terminal device uses social software such as WeChat to play voice or answer an incoming call and the like.
The output power of the first audio component 140 in the speaker operating mode is larger, and the volume of sound heard by the user is larger, for example, the volume of sound is 85 db, and even can reach 150 db at most, at this time, the volume of sound exceeds the range of the human ear, and the human ear can be far away from the sound outlet hole. The working mode of the loudspeaker is suitable for the scene needing larger output sound volume. For example, in a scene such as a ringing sound of a terminal device, an incoming music sound of a terminal device, or a video or music played by a terminal device.
The embodiment of the present disclosure utilizes the difference of the output power of the first audio component 140, so that the first audio component 140 has the working mode of the speaker and the working mode of the receiver at the same time, and the receiver and the speaker are combined into one. The earphone function and the loudspeaker function can be realized only by one audio component, at least one piece of hardware is reduced, the earphone function and the loudspeaker function are not required to be realized by two audio modules respectively, the hardware cost is saved, meanwhile, the occupied space is also reduced, for example, the limitation of the audio modules on the layout of the stacked circuit boards in the terminal is reduced, and the terminal containing the audio module is favorably thinned.
In other alternative embodiments, the sound outlet port comprises: at least one first sound outlet 131 and at least one second sound outlet 111;
wherein the first sound emitting hole 131 and the at least one second sound emitting hole 111 are in communication with the first sound cavity 112 on different sides of the first sound cavity 112.
The sound emitting holes include two first sound emitting holes 131 and two second sound emitting holes 111, which is also beneficial to enlarging the area of the opening.
The first audio component 140 will sound both the first sound outlet 131 and the second sound outlet 111 whether in an earpiece mode or in a speaker mode of operation.
The first sound emitting hole 131 and the second sound emitting hole 111 are located on different sides of the first sound cavity 112, and include: the first sound emitting hole 131 and the second sound emitting hole 111 are respectively located at adjacent sides of the first sound cavity 112, or the first sound emitting hole 131 and the second sound emitting hole 111 are respectively located at opposite sides of the first sound cavity 112. When the first sound emitting hole 131 and the second sound emitting hole 111 are located at opposite sides of the first sound chamber 112, respectively, the user can sense sounds in different directions more easily, and thus stereo surround sound is realized.
The position of the first sound emitting hole 131 and the position of the second sound emitting hole 111 may be independently set as needed. In practical applications, the first sound outlet hole 131 can be located more suitable for being close to the ear, for example, the first sound outlet hole 131 is located in front of the first sound cavity 112, so that when the receiver is used in the working mode, the first sound outlet hole 131 is aligned with the ear of the user, and the communication privacy is ensured, and at this time, the first sound outlet hole 131 is reused as the receiver sound outlet hole. The position of the second sound outlet hole 111 is more suitable for external use, for example, the second sound outlet hole 111 is located on the top surface of the first sound cavity 112, so that the possibility that the second sound outlet hole 111 is blocked due to different placing modes of the audio module can be reduced, the normal operation of the speaker working mode is ensured, and at this time, the second sound outlet hole 111 is multiplexed into the speaker sound outlet hole.
In other optional embodiments, the audio module further comprises:
a second sound cavity; wherein the second acoustic chamber and the first acoustic chamber 112 are separated at different locations by the first audio component 140.
In practical applications, the second cavity is used as a back cavity of the first audio component 140, and needs to be completely separated from the first cavity 112 to ensure the sound cavity to correct the sound, thereby improving the sound quality. Typically, the volume of the first acoustic chamber 112 is smaller than the volume of the second acoustic chamber.
An embodiment of the present disclosure further provides a terminal, including:
a middle frame 110 having a mounting location 118;
a first audio component 140 mounted on the mounting location 118 and having a speaker mode of operation as a speaker and an earpiece mode of operation as an earpiece; wherein, the output power of the first audio component 140 in the speaker operating mode is greater than the output power of the first audio component 140 in the earpiece operating mode;
a sound outlet hole located on the middle frame 110 for outputting the sound output by the first audio module 140;
the first sound cavity 112 is located in the middle frame 110 and is respectively communicated with the first audio component 140 and the sound outlet.
The terminal can be a mobile terminal such as a mobile phone, a tablet computer, a notebook computer, or the like, or a wearable electronic device such as a smart watch, or a vehicle-mounted device such as a vehicle-mounted navigation device, without limitation.
In the embodiment of the present disclosure, the first audio component 140 may be the same as the first audio component 140 of any of the above embodiments. The first sound chamber 112 and the sound outlet may both be defined by the middle frame 110.
Without limitation, mounting locations 118 may be grooves and/or openings, such as by machining grooves into center frame 110. The recess may also have an opening, for example.
The first audio component 140 may cover the opening, sealing the recess to form the first acoustic chamber 112. And a sound outlet hole is formed by machining and punching, so that the sound outlet hole is communicated with the first sound cavity 112.
As shown in fig. 2, 3, 6 and 8, the first acoustic cavity 112 is a bending type acoustic transmission channel, and the first acoustic cavity 112 according to the embodiment of the present disclosure may increase the length of the acoustic transmission channel compared to a straight type acoustic transmission channel. Therefore, the attenuation length of noise caused by vibration of the device of the terminal equipment can be increased, the noise in the terminal equipment can be attenuated more, and the audio output effect of the terminal equipment is improved.
The middle frame 110 serves as a support frame of the terminal, and is used for fixing and supporting functional devices such as the circuit board 150, the display screen 120, the rear case 160 or the battery cover 170 of the terminal, and the strength of the middle frame 110 directly affects the strength of the whole terminal. The material of the middle frame 110 can be selected from metal, alloy, or composite material of plastic and alloy. In a specific example, the middle frame 110 is made of an aluminum alloy, and the middle frame 110 can also be reused as an antenna.
Generally, the first audio component 140 is mounted on top of the middle frame 110, and the first sound cavity 112 and the sound outlet are located on top of the middle frame 110, so as to facilitate the use of the earpiece operation mode and the speaker operation mode.
The embodiment of the present disclosure utilizes the difference of the output power of the first audio component 140, so that the first audio component 140 has the working mode of the speaker and the working mode of the receiver at the same time, and the receiver and the speaker are combined into one. The earphone function and the loudspeaker function can be realized only by installing one audio component in the terminal, at least one piece of hardware is reduced, the earphone function and the loudspeaker function are not required to be realized by adopting two audio modules respectively, the hardware cost is saved, meanwhile, the occupied space is also reduced, for example, the limitation of the audio module on the layout of a stacked circuit board in the terminal is reduced, and the realization of the lightness and thinness of the terminal comprising the audio module is facilitated.
In other alternative embodiments, the sound outlet port comprises: at least one first sound outlet 131 and at least one second sound outlet 111;
wherein the first sound emitting hole 131 and the at least one second sound emitting hole 111 are in communication with the first sound chamber 112 on different sides of the middle frame 110.
After passing through the first sound cavity 112, the sound output from the first audio component 140 can be transmitted to the outside of the terminal through the first sound output hole 131 and the second sound output hole 111 at the same time, and then heard by the user. As shown in fig. 1 to 4, wherein arrows in fig. 2 and 3 are directed to a transmission direction of sound. Similar to the sound output holes of the above embodiments, the first sound output hole 131 and the second sound output hole 111 can be disposed on different sides (i.e. different surfaces) of the middle frame 110 as required, so that the first sound output hole 131 is multiplexed as a receiver sound output hole, and the second sound output hole 111 is multiplexed as a speaker sound output hole, which facilitates the use of the first audio component 140 in different working modes.
Further, the shape and number of the first sound emitting hole 131 and the second sound emitting hole 111 may be independently provided. For example, the first sound emitting hole 131 is rectangular, and one or more holes may be provided. The second sound emitting hole 111 has a circular shape, an oval shape, a rectangular shape, or the like, and the number of the second sound emitting holes 111 may be plural.
The plurality of first sound outlet holes 131 may be adjacently distributed on the same side of the middle frame 110. The plurality of second sound outlet holes 111 may also be adjacently distributed on the other side of the middle frame 110.
In other alternative embodiments, the first sound outlet 131 is located on the first surface 113 of the middle frame 110, and the mounting location 118 is located on the second surface 114 of the middle frame 110, wherein the second surface 114 is opposite to the first surface 113;
the second sound outlet hole 111 is located on a third surface 115 of the middle frame 110, and the third surface 115 is perpendicular to the first surface 113 and the second surface 114.
The terminal is a mobile phone, for example, as shown in fig. 1 to 4, the first surface 113 of the middle frame 110 is the front surface of the terminal opposite to the user. The first sound outlet hole 131 is disposed on the first surface 113, so that when the user answers the phone call, the first surface 113 is close to the ear according to the speaking habit of the user, and the first sound outlet hole 131 is more suitable for being used as a receiver sound outlet hole. In addition, the mobile phone is generally shaped like a straight plate, and in the speaker operation mode, the mobile phone is placed on a supporting surface such as a table, and the first surface 113 or the second surface 114 of the middle frame 110 is supported on the supporting surface, so that the first sound outlet hole 131 is more likely to be blocked by the supporting surface. While other sides of the middle frame 110, such as the third surface 115, are usually far away from the supporting surface, the second sound outlet hole 111 is less likely to be folded, and the sound emitted from the second sound outlet hole 111 is less affected.
In other optional embodiments, the terminal further includes:
a second audio assembly mounted on the middle frame 110 and spaced apart from the first audio assembly 140;
the middle frame 110 further has a third sound outlet 119, and the third sound outlet 119 is used for outputting the sound output by the second audio component to the outside;
the orientation of the third sound outlet 119 is opposite to the orientation of the second sound outlet 111.
Similar to the first audio component 140, the second audio component is a transducer device that converts an electrical signal into an acoustic signal, and includes, but is not limited to, an electrodynamic audio component, an electromagnetic audio component, or a piezoelectric audio component.
When the first audio component 140 is in the speaker operation mode, the second audio component and the first audio component 140 output sound simultaneously, so that the user can perceive sound from different directions, and the sound generates surround, as indicated by the arrow in fig. 10, to realize a stereo effect. Moreover, the first audio component 140 and the second audio component both output sound at the same time, which is also beneficial to increasing the volume.
In practical applications, the second audio component and the third sound outlet 119 are both located at the bottom of the middle frame 110, and the third sound outlet 119 and the second sound outlet 111 are distributed on two opposite surfaces of the middle frame 110. For example, as shown in fig. 2, 4, 6, 8, and 10, the second sound outlet hole 111 is located on the top end surface of the middle frame 110, and the third sound outlet hole 119 is located on the bottom end surface of the middle frame 110.
As shown in fig. 11, if two audio components are respectively disposed at the top of the middle frame 30, and are respectively used as the earpiece audio component and the first speaker audio component 10, and another audio component is further disposed at the bottom of the middle frame 30 and is used as the second speaker component 20, the second speaker component 20 and the first speaker component 10 output sound simultaneously to realize stereophonic sound, such a structure may increase the occupation of the audio components to the top space, and moreover, the sound cavities of the two audio components at the top also need to be respectively disposed, which further increases the occupation of the internal space of the terminal.
In other alternative embodiments, the first surface 113 of the middle frame 110 further has an opening 117 communicating with the first acoustic chamber 112;
the terminal further includes:
a bracket 130 covering the opening 117 of the first surface 113 of the middle frame 110 and sealing the first sound cavity 112; the holder 130 has a through hole communicating with the opening 117, which is multiplexed as a first sound outlet hole 131;
and the display screen 120 is arranged on the bracket 130 and is positioned below the through hole.
As shown in fig. 7 to 9, wherein fig. 7 and 8 show only the middle frame 110. In order to facilitate the installation of the functional devices, when the middle frame 110 is provided with a groove, an opening 117 may be further formed on the first surface 113 of the middle frame 110, and the bracket 130 covers the opening 117 to seal the groove to form the first sound cavity 112. The bracket 130 and the middle frame 110 together form a first sound cavity 112 and a first sound outlet 131.
As shown, an adhesive may be disposed around the opening 117 by dispensing, and fig. 5 exemplarily shows a trace 116 of the adhesive, and the bracket 130 and the middle frame 110 are fixed by bonding with the adhesive. In this way, the sealing effect of the bracket 130 is ensured, the leakage of sound is reduced, and the sound can be conducted to the outside of the first surface 113 along the first sound cavity 112 through the first sound outlet 131.
To ensure the sealing effect, the bracket 130 may be made of an elastic material such as plastic.

when the working mode is a loudspeaker working mode, sending a first control signal to the driving circuit, wherein the first control signal is used for controlling the driving circuit to output a driving signal with first power to the first audio component;
when the working mode is an earphone working mode, sending a second control signal to the driving circuit, wherein the second control signal is used for controlling the driving circuit to output a driving signal with second power to the first audio component; the second power is less than the first power.
In an embodiment of the disclosure, the first power and the second power may be used to define a power range, and the power range may include: maximum power and minimum power. Without limitation, the maximum power of the second power does not exceed the minimum power of the first power.
In other optional embodiments, the determining the operation mode of the first audio component includes:
and determining the working mode of the first audio component according to the application scene of the mobile terminal containing the first audio component or the detection of user input.
In practical applications, when the mobile terminal including the first audio component is in a quieter application scenario, for example: library, exhibition room or meeting room, etc., the operating mode of the first audio component may be determined to be the earpiece operating mode. When the mobile terminal containing the first audio component is in a noisy application scenario, for example: an outdoor block or concert, etc., the operating mode of the first audio component may be determined to be a speaker operating mode.
In a specific example, if a terminal with the first audio component receives an incoming call, the call is automatically determined to be a call scene, an earphone working mode is adopted by default, and if a hands-free play scene or the like is monitored, the mode is switched to a loudspeaker mode. If the terminal with the first audio component is in a multimedia information output scene, such as music playing and video playing, the multimedia information playing scene is determined, and a speaker mode is adopted by default.
The operating mode may also be determined based on instructions input by the user. For example, a user may enter an instruction to place the first audio component in an earpiece mode of operation or a speaker mode of operation via an interactive interface of the display screen, a user voice input, or a typing input.
