Description

Technical Field

The present application belongs to the technical field of electronic devices and relates to an electronic device and a sound generation method of the electronic device.

Background technique

With the development of science and technology, mobile phones, tablets and other electronic devices have become important tools for people to use. Among them, audio calls and external speakers are one of the most basic and important functions of such electronic devices. Taking mobile phones as an example, in the relevant technology, the common design method is to install only a receiver on the top of the mobile phone and a speaker on the bottom of the mobile phone.

However, in the above design, in the external speaker mode, the receiver and the speaker work at the same time, but because the size and power of the receiver are generally smaller than the speaker, the sound emitted by the receiver is smaller than that of the speaker, resulting in a poor audio stereo effect. At the same time, in the call mode, only the top receiver works, and the sound pressure leaked from the receiver to the user's surroundings is also relatively large, and the call privacy is poor. Although the amount of surrounding sound leakage can be reduced by lowering the volume, the sound pressure in the user's ear will also decrease, affecting the acoustic experience.

Therefore, how to solve the defects of the prior art such as the inability to further improve the call quality in the external speaker mode and the handheld call mode has become a technical problem that needs to be solved urgently by those skilled in the art.

Summary of the invention

The purpose of the present application is to provide an electronic device and a sound generation method of the electronic device, so as to solve the problem that the prior art cannot further improve the call quality in the external speaker mode and the handheld call mode.

To achieve the above-mentioned purpose and other related purposes, on one hand, an embodiment of the present application provides an electronic device, which includes: a device body; a first receiver and a first sound outlet; the first receiver is arranged in the device body, the first sound outlet is opened on the upper part or top side of the device body surface, and is connected to the first receiver, and the first receiver emits a first sound wave through the first sound outlet; a second receiver and a second sound outlet; the second receiver is arranged in the device body, the second sound outlet is opened on the side or back of the device body, and is connected to the second receiver, the second receiver emits a second sound wave through the second sound outlet, and the first sound wave and the second sound wave have the same or opposite phase.

In a possible implementation, it further includes: a speaker and a third sound outlet hole; the speaker is disposed in the device body, the third sound outlet hole is opened at the lower part or bottom side of the surface of the device body and is connected to the speaker, and the speaker emits a third sound wave through the third sound outlet hole.

In a possible implementation manner, the first receiver is disposed on an upper portion of the device body.

In a possible implementation manner, the first sound outlet is opened at a central position on an upper portion of a surface of the device body.

In a possible implementation manner, the distance between the first sound outlet hole and the second sound outlet hole is within a preset distance range.

In a possible implementation manner, the preset distance range is determined by specifications of the first receiver and the second receiver and an in-ear sound pressure.

In a possible implementation, the electronic device further includes: a first audio drive unit and a second audio drive unit; the first receiver is electrically connected to the first audio drive unit, and the second receiver is electrically connected to the second audio drive unit; when the electronic device is in an external speaker mode, the first audio drive unit and the second audio drive unit emit electrical signals with the same phase, so that the first sound wave and the second sound wave have the same phase; when the electronic device is in a non-external speaker mode, the first audio drive unit and the second audio drive unit emit electrical signals with opposite phases, so that the first sound wave and the second sound wave have opposite phases.

In a possible implementation manner, a sound pressure amplitude of a first sound wave emitted by the first receiver through the first sound outlet hole is equal to a sound pressure amplitude of a second sound wave emitted by the second receiver through the second sound outlet hole.

In a possible implementation, the second sound outlet hole is opened at a central position on the back side of the device body, and a central axis of the second sound outlet hole and a central axis of the first sound outlet hole are located on the same vertical plane.

In a possible implementation manner, the sound pressure amplitudes of the first sound wave and the second sound wave are equal.

In a possible implementation, the distance between the first sound outlet and the first ear hole of the user of the electronic device is a first distance, and the distance between the third sound outlet and the second ear hole of the user of the electronic device is a second distance, wherein the first ear hole is an ear hole close to the first sound outlet, and the second ear hole is an ear hole close to the third sound outlet. When the first distance is close to the second distance and the phases of the first sound wave and the second sound wave are the same: the sound pressure entering the ear through the first ear hole is close to the sound pressure entering the ear through the second ear hole.

To achieve the above-mentioned purpose and other related purposes, another aspect of an embodiment of the present application provides a method for sound generation of an electronic device, which is applied to the electronic device; the method comprises: the first receiver emits a first sound wave through the first sound outlet hole, and the second receiver emits a second sound wave through the second sound outlet hole, and the first sound wave and the second sound wave have the same or opposite phase.

On the one hand, in the external speaker mode, the main and auxiliary receivers emit sound waves with the same phase, which can enhance the surrounding sound field and make the electronic device have a good external stereo effect. On the other hand, in the call mode, the main and auxiliary receivers emit sound waves with opposite phases, which can weaken the surrounding sound field, reduce the sound leakage around the user, and improve the privacy of the call.

At the same time, due to the difference in the distance between the main sound outlet connected to the main receiver and the secondary sound outlet connected to the secondary receiver and the user's ear hole, the sound waves received by the user are mainly emitted by the main receiver, and the secondary receiver has a very small offset to the sound pressure entering the user's ear. By reasonably setting the acoustic specifications and installation positions of the main and secondary receivers, the effect of the secondary receiver on the sound pressure entering the user's ear can even be ignored. In this way, the sound pressure entering the user's ear is guaranteed to remain unchanged or to be reduced very little, but the surrounding sound pressure is significantly reduced. While ensuring the user's acoustic experience, it also reduces sound leakage and improves call privacy.

The first sound outlet 6, the second sound outlet 7 and the third sound outlet 9 are respectively opened on the device body.

For example, the first sound hole 6, the second sound hole 7 and the third sound hole 9 are all located on the center line of the mobile phone, and the first sound hole 6 and the second sound hole 7 are spaced 10 mm to 30 mm apart; the first sound hole 6 and the third sound hole 9 are respectively located at the top and the bottom of the mobile phone.

In one embodiment, the first receiver 4 is a main receiver, and the first sound outlet 6 is a main sound outlet; the main receiver is disposed on the upper part of the device body. Specifically, the main sound outlet is opened in the middle of the upper part of the device body surface.

In one embodiment, the first receiver 4 is disposed on the upper portion of the device body. The first sound outlet 6 is opened at the center of the upper portion of the surface of the device body.

In one embodiment, the second receiver 5 is an auxiliary receiver, and the second sound outlet 7 is an auxiliary sound outlet; the auxiliary receiver is disposed in the device body, and the distance between the main sound outlet and the auxiliary sound outlet is within a preset distance range.

In one embodiment, the second sound outlet 7 is provided at the center of the back of the device body, and the central axis of the second sound outlet 7 and the central axis of the first sound outlet 6 are located on the same vertical plane. Typically, the shell of the device body includes a first shell 1, a second shell 2 and a frame 3. In some examples, the first shell 1 is also called a cover plate, the second shell 2 is called a back cover, and the frame 3 is called a middle frame. The first shell 1, the second shell 2 and the frame 3 together enclose an internal cavity of the device body for accommodating electronic devices, wherein the electronic devices include processors, memories, camera chips, various sensor chips, batteries, etc.

It should be noted that the shape, size, and material of the first shell, the second shell, and the frame in this application are not limited. They can be the shell and frame shapes of common electronic devices such as existing mobile phones and tablets, or they can be various custom regular or irregular shell and/or frame shapes. For example, the first shell is a transparent form made of glass, and the second shell can be made of metal, ceramic, microcrystalline glass or other materials. The frame is usually made of metal. For another example, the shell that constitutes the device body can be a straight surface, a curved surface, or a folded form. The front shell, back shell, upper part, bottom, lower part, etc. defined in this application for the first shell, the second shell, and the frame are all relative descriptions. The actual design may not be limited to the orientation design described in the embodiments of this application.

In one embodiment, the preset distance range is determined by specifications of the first receiver and the second receiver and in-ear sound pressure.

Please continue to refer to Figure 1. The electronic device is a mobile phone as an example. The mobile phone includes a device body composed of a front shell 1, a rear shell 2 and a frame 3, and a main receiver 4, a secondary receiver 5, at least one main sound hole 6, and at least one secondary sound hole 7 are installed on the top of the mobile phone, as well as a speaker 8 installed at the bottom of the mobile phone, and at least one third sound hole 9. The main sound hole 6 is centrally arranged on the front of the mobile phone and close to the top, the secondary sound hole 7 is opened on the rear shell of the mobile phone, and the third sound hole 9 is arranged on the front of the mobile phone and close to the bottom. Among them, the main receiver 4 is connected to the main sound hole 6, the secondary receiver 5 is connected to the secondary sound hole 7, and the speaker 8 is connected to the third sound hole 9.

In one embodiment, the electronic device further includes: a first audio driving unit and a second audio driving unit.

The first receiver is electrically connected to the first audio driving unit, and the second receiver is electrically connected to the second audio driving unit.

When the electronic device is in an external speaker mode, the first audio driving unit and the second audio driving unit send out electrical signals with the same phase, so that the first sound wave and the second sound wave have the same phase; when the electronic device is in a non-external speaker mode, the first audio driving unit and the second audio driving unit send out electrical signals with opposite phases, so that the first sound wave and the second sound wave have opposite phases. Specifically, the non-external speaker mode refers to a mode that can realize a private call, such as a handheld call mode.

Please refer to FIG2, which shows a schematic diagram of the working principle of the auxiliary receiver of an electronic device in an embodiment of the present application. As shown in FIG2, in the external speaker mode, the speaker, the main receiver and the auxiliary receiver work simultaneously, and the auxiliary receiver emits sound waves with the same phase as the main receiver, enhancing the surrounding sound field, so that the electronic device has a good external speaker stereo effect. In the handheld call mode, the speaker does not work, and the auxiliary receiver emits sound waves with the opposite phase to the main receiver, weakening the surrounding sound field, reducing the amount of sound leakage around the user, and improving the privacy of the call.

In one embodiment, the first sound outlet is disposed on the top of the first housing or the top of the frame.

In one embodiment, the second sound outlet hole is opened at a central position on the back side of the device body, and a central axis of the second sound outlet hole and a central axis of the first sound outlet hole are located on the same vertical plane.

In one embodiment, the distance between the first sound outlet and the first ear hole of the user of the electronic device is a first distance, and the distance between the third sound outlet and the second ear hole of the user of the electronic device is a second distance, wherein the first ear hole is an ear hole close to the first sound outlet, and the second ear hole is an ear hole close to the third sound outlet. When the first distance is close to the second distance and the phases of the first sound wave and the second sound wave are the same: the sound pressure entering the ear of the first ear hole is close to the sound pressure entering the ear of the second ear hole.

Please refer to FIG3, which is a schematic diagram of the position of the sound outlet of an electronic device in an embodiment of the present application. As shown in FIG3, in the external speaker mode, the smaller the distance D between the main sound outlet and the auxiliary sound outlet, the more obvious the enhancement effect on the far-field sound waves and the better the stereo effect. In the handheld call mode, the smaller the distance D between the main sound outlet and the auxiliary sound outlet, the more obvious the attenuation effect on the far-field sound waves, but the greater the attenuation of the user's in-ear sound pressure; conversely, the larger the D, the weaker the attenuation effect on the far-field sound waves, but the attenuation of the user's in-ear sound pressure also becomes smaller. Therefore, the size of the distance D should be determined comprehensively according to the actual specifications of the main and auxiliary receivers and the in-ear sound pressure. Since the sound field after the superposition of the main and auxiliary receivers is directional, preferably, the auxiliary sound outlet can be set on the central axis of the main sound outlet, and the main receiver and the auxiliary receiver with equal sound pressure amplitude are selected, so as to ensure that the in-ear sound pressure radiated to the user in the handheld call mode is the maximum.

In one embodiment, the third sound outlet is disposed at the bottom of the first housing or the bottom of the frame.

In one embodiment, the number of the first sound outlet hole, the second sound outlet hole and the third sound outlet hole is at least one.

It should be noted that the present application does not limit the size and shape of the first sound hole, the second sound hole and the third sound hole, and any design of size and/or shape that can meet the principle of the electronic device of the present application is within the scope of protection of the present application.

Specifically, considering the limitation of the actual installation space, the secondary sound hole can be set at other positions besides the central axis of the device, such as the side of the middle frame of the mobile phone. The main sound hole can be set at the top of the front shell of the mobile phone, or at the top of the middle frame. The tertiary sound hole can be at the bottom of the front shell of the mobile phone, or at the bottom of the middle frame, both of which can achieve the effect of stereo enhancement and increased privacy.

It should be noted that the present application does not limit the positions of the first sound hole, the second sound hole and the third sound hole. Except for the positions of the first sound hole, the second sound hole and the third sound hole listed in the text, any design method of the position that can meet the principle of the electronic device of the present application is within the scope of protection of the present application.

In one embodiment, the sound pressure amplitudes of the first sound wave emitted by the first receiver through the first sound outlet hole and the second sound wave emitted by the second receiver through the second sound outlet hole are equal.

Please refer to FIG4 , which is a schematic diagram of stereo sound in the external speaker mode of an electronic device in an embodiment of the present application. As shown in FIG4 , the size and power of the speaker installed at the bottom of the mobile phone are greater than the main and auxiliary receivers installed at the top. Preferably, when the user is facing the mobile phone in the center, the sound pressure transmitted to the left ear by the speaker is the same as the sound pressure transmitted to the right ear after the main and auxiliary receivers are superimposed, so that the stereo effect is also the best.

In the handheld call mode, the sound pressure entering the ear of the user is closer to the ear hole than the secondary sound hole because the distance between the main sound hole and the ear hole is closer than that between the secondary sound hole and the ear hole. For example, if the distance between the main sound hole and the user's ear hole is 10mm and the distance between the secondary sound hole and the user's ear hole is 30mm, the sound pressure level transmitted from the secondary receiver to the user's ear hole is attenuated by 20log(30/10)≈9.5dB more than that of the main receiver. Therefore, the sound pressure received by the user's ear hole is mainly emitted by the main receiver, and the offset effect of the secondary receiver can be basically ignored. For the far-field environment around the user, for example, at a distance of 50cm from the user, the distance from the main receiver to the main sound hole and the distance from the secondary receiver to the secondary sound hole are basically equal, and the sound pressure level attenuation values emitted by the two sound units are equal, so the sound pressure at the far-field position is the negative superposition of the two, which can achieve good sound wave offset and reduce the amount of sound leakage radiated to the surrounding environment.

In practical applications, the electronic device described in the present application may further include a processor and a memory. The memory is used to store a computer program, and the processor is used to execute the computer program stored in the memory, so that the electronic device executes the electronic device sound generation method of the present application.

The above-mentioned processor can be a general-purpose processor, including a central processing unit (CPU), a network processor (NP), etc.; it can also be a digital signal processor (DSP), an application specific integrated circuit (ASIC), a field programmable gate array (FPGA) or other programmable logic devices, discrete gates or transistor logic devices, discrete hardware components.

The above-mentioned memory may include a random access memory (RAM), and may also include a non-volatile memory (non-volatile memory), such as at least one disk memory.

Please refer to Figure 5, which shows a principle flow chart of the sound-generating method of an electronic device in an embodiment of the present application. As shown in Figure 5, the sound-generating method of an electronic device described in the present application is applied to the electronic device. In combination with Figures 1 to 4, the electronic device includes: a device body, the device body includes a first shell, a second shell and a frame; a first receiver and a first sound outlet, the first receiver is arranged in the device body and communicated with the first sound outlet; a second receiver and a second sound outlet, the second receiver is arranged in the device body and communicated with the second sound outlet; a speaker and a third sound outlet, the speaker is arranged in the device body and communicated with the third sound outlet; the first sound outlet, the second sound outlet and the third sound outlet are respectively opened on the device body; the method includes: the first receiver emits a first sound wave through the first sound outlet, the second receiver emits a second sound wave through the second sound outlet, and the first sound wave and the second sound wave have the same or opposite phase.

In one embodiment, the electronic device further includes: a first audio driving unit and a second audio driving unit; the first receiver is electrically connected to the first audio driving unit, and the second receiver is electrically connected to the second audio driving unit, and the method specifically includes the following steps:

S51, determining the sound emission mode of the electronic device.

S52: When the electronic device is in an external speaker mode, the first audio driving unit and the second audio driving unit send out electrical signals with the same phase, so that the first sound wave and the second sound wave have the same phase.

S53: When the electronic device is in a non-speaker mode, the first audio driving unit and the second audio driving unit send out electrical signals with opposite phases, so that the first sound wave and the second sound wave have opposite phases.

In one embodiment, the electronic device further includes: a speaker and a third sound outlet; the speaker is disposed in the device body, the third sound outlet is opened at the lower part or bottom side of the surface of the device body and is connected to the speaker, and the speaker emits a third sound wave through the third sound outlet.

In one embodiment, the first receiver is disposed on the upper portion of the device body.

In one embodiment, the first sound outlet is opened at a central position on an upper portion of a surface of the device body.

In one embodiment, the distance between the first sound outlet hole and the second sound outlet hole is within a preset distance range.

In one embodiment, the preset distance range is determined by the specifications of the first receiver and the second receiver and the in-ear sound pressure.

In one embodiment, the distance between the first sound outlet and the first ear hole of the user of the electronic device is a first distance, and the distance between the third sound outlet and the second ear hole of the user of the electronic device is a second distance, wherein the first ear hole is an ear hole close to the first sound outlet, and the second ear hole is an ear hole close to the third sound outlet. When the first distance is close to the second distance and the phases of the first sound wave and the second sound wave are the same: the sound pressure entering the ear of the first ear hole is close to the sound pressure entering the ear of the second ear hole.

Specifically, the preset distance range may actually refer to the distance between the sound outlet of the first receiver and the sound outlet of the second receiver. When the distance between the two sound outlets is set to be smaller, the amount of sound leakage to the outside world is smaller, but at the same time it will have a negative effect on the user's in-ear sound pressure; when the distance between the two sound outlets is set to be larger, the impact on the user's in-ear sound pressure is smaller, but the amount of sound leakage to the outside world will also increase. Therefore, for the main and auxiliary receivers with better acoustic performance, the distance between the two sound outlets can be appropriately reduced. Although this will reduce the user's in-ear sound pressure, due to the high initial performance of the receiver, it can still maintain a high in-ear sound pressure; for the main and auxiliary receivers with poor acoustic performance, in order to ensure that the user's in-ear sound pressure is not too small, it is necessary to appropriately increase the distance between the two sound outlets.

In one embodiment, the sound pressure amplitudes of the first sound wave emitted by the first receiver through the first sound outlet hole and the second sound wave emitted by the second receiver through the second sound outlet hole are equal.

In one embodiment, the second sound outlet hole is opened at a central position on the back side of the device body, and a central axis of the second sound outlet hole and a central axis of the first sound outlet hole are located on the same vertical plane.

In one embodiment, the sound pressure amplitudes of the first sound wave and the second sound wave are equal.

The protection scope of the electronic device sound production method described in the present application is not limited to the execution order of the steps listed in this embodiment. All solutions implemented by adding, reducing or replacing steps in the prior art based on the principles of the present application are included in the protection scope of the present application.

The principle of the electronic device sound-emitting method described in the present application corresponds one-to-one to the electronic device described in the present application. The electronic device described in the present application can implement the electronic device sound-emitting method described in the present application. However, the implementation device of the electronic device sound-emitting method described in the present application includes but is not limited to the structure of the electronic device listed in this embodiment. All structural deformations and replacements of the prior art made according to the principles of the present application are included in the protection scope of the present application.

In summary, the electronic device and the electronic device sound-generating method described in the present application emit sound waves with the same or opposite phases through the two sound-generating units, the main and auxiliary receivers, installed on the device, to enhance or weaken the far-field sound pressure. On the one hand, in the external speaker mode, the main and auxiliary receivers emit sound waves with the same phase, which can enhance the surrounding sound field, so that the electronic device has a good external speaker stereo effect. On the other hand, in the call mode, the main and auxiliary receivers emit sound waves with opposite phases, which can weaken the surrounding sound field, reduce the amount of sound leakage around the user, and improve the privacy of the call. At the same time, due to the difference in the distance between the main sound outlet connected to the main receiver and the auxiliary sound outlet connected to the auxiliary receiver from the user's ear hole, the sound waves received by the user are mainly emitted by the main receiver, and the auxiliary receiver offsets the user's in-ear sound pressure very little. By reasonably setting the acoustic specifications and installation positions of the main and auxiliary receivers, the influence of the auxiliary receiver on the user's in-ear sound pressure can even be ignored. In this way, it is ensured that the user's in-ear sound pressure remains unchanged or is reduced very little, but the surrounding sound pressure is significantly reduced. While ensuring the user's acoustic experience, it also reduces sound leakage and improves call privacy.

The above embodiments are merely illustrative of the principles and effects of the present application and are not intended to limit the present application. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present application. Therefore, all equivalent modifications or changes made by a person of ordinary skill in the art without departing from the spirit and technical ideas disclosed in the present application shall still be covered by the claims of the present application.
