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

When the electronic equipment is in a play mode, the first audio driving unit and the second audio driving unit emit electric signals with the same phase, so that the phases of the first sound wave and the second sound wave are the same; in the non-play mode of the electronic device, the first audio driving unit and the second audio driving unit emit electric signals with opposite phases, so that the first sound wave and the second sound wave have opposite phases. Specifically, the non-play mode refers to a handheld call mode or other modes capable of realizing a private call.
Please refer to fig. 2, which is a schematic diagram illustrating a working principle of a secondary receiver of an electronic device according to an embodiment of the present application. As shown in fig. 2, in the loudspeaker, the main receiver and the sub-receiver operate simultaneously in the loudspeaker-in-loudspeaker mode, and the sub-receiver emits sound waves with the same phase as the main receiver to enhance the surrounding sound field, so that the electronic device has a good loudspeaker effect. In a handheld call mode, the loudspeaker does not work, the auxiliary receiver sends sound waves with phases opposite to those of the main receiver, surrounding sound fields are weakened, sound leakage around a user is reduced, and call privacy is improved.
In an embodiment, the first sound outlet is disposed at the top of the first housing or the top of the frame.
In an embodiment, the second sound outlet is provided at a central position of the back of the device body, and a central axis of the second sound outlet and a central axis of the first sound outlet are located on the same vertical plane.
In an embodiment, a distance between the first sound emitting hole and a first ear hole of the electronic device user is a first distance, a distance between the third sound emitting hole and a second ear hole of the electronic device user is a second distance, wherein the first ear hole is an ear hole close to the first sound emitting hole, the second ear hole is an ear hole close to the third sound emitting hole, and 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 of the first ear hole is close to the sound pressure of the second ear hole.
Please refer to fig. 3, which is a schematic diagram illustrating a position of a sound outlet of an electronic device according to an embodiment of the present application. As shown in fig. 3, in the play mode, the smaller the distance D between the primary sound outlet and the secondary sound outlet, the more significant the enhancement effect on the far-field sound wave, and the better the stereo effect. In the handheld communication mode, the smaller the distance D between the main sound outlet hole and the auxiliary sound outlet hole is, the more obvious the attenuation effect on the far-field sound wave is, but the greater the attenuation on the in-ear sound pressure of a user is; conversely, the larger D, the weaker the sound wave attenuation effect on the far field, but the smaller the sound pressure attenuation on the user's ear. Therefore, the distance D is determined comprehensively according to the actual specifications of the main and sub-receivers and the sound pressure of the ear. Because the sound field of the superposed main and auxiliary receivers has directivity, preferably, the auxiliary sound outlet hole can be arranged on the central axis of the main sound outlet hole, and the main receiver and the auxiliary receiver with equal sound pressure amplitude are selected, so that the maximum sound pressure of the sound radiated to the ear of a user can be ensured in a handheld conversation mode.
In an embodiment, the third sound outlet is disposed at the bottom of the first housing or the bottom of the frame.
In an embodiment, the number of the first sound emitting hole, the second sound emitting hole and the third sound emitting hole is at least one.
It should be noted that, the size and shape of the first sound outlet, the second sound outlet, and the third sound outlet are not limited in this application, and any design manner of size and/or shape that can satisfy the principle of the electronic device of this application is within the scope of protection of this application.
Specifically, the secondary sound outlet hole may be disposed at a position other than the central axis of the device, such as a side surface of the middle frame of the mobile phone, in consideration of the limitation of the actual installation space. The main sound outlet hole can be arranged at the top of the front shell of the mobile phone or at the top of the middle frame. The third sound outlet hole can be arranged at the bottom of the front shell of the mobile phone or at the bottom of the middle frame, and the effects of enhancing the stereo and increasing the privacy can be realized.
It should be noted that, the positions of the first sound outlet, the second sound outlet, and the third sound outlet are not limited in the present application, and any design manner that can satisfy the positions of the electronic device of the present application except the positions of the first sound outlet, the second sound outlet, and the third sound outlet, which are exemplified in the text, is within the scope of protection of the present application.
In an embodiment, the sound pressure amplitudes of the first sound wave emitted by the first receiver through the first sound emitting hole and the second sound wave emitted by the second receiver through the second sound emitting hole are equal.
Please refer to fig. 4, which is a schematic stereo diagram of an electronic device in a play-out mode according to an embodiment of the present application. As shown in fig. 4, the size and power of the speaker installed at the bottom of the cellular phone are larger than those of the main and sub-receivers installed at the top. Preferably, when the user is centered and faces the mobile phone, the sound pressure transmitted to the left ear by the loudspeaker is the same as the sound pressure transmitted to the right ear after the main receiver and the auxiliary receiver are superposed, so that the stereo effect is also best.
Under the handheld conversation mode, for the sound pressure of the user entering the ear, the distance between the main sound outlet and the ear hole is closer to the ear hole than the auxiliary sound outlet. For example, if the primary sound outlet is 10mm away from the ear canal of the user and the secondary sound outlet is 30mm away from the ear canal of the user, the sound pressure level transmitted from the secondary receiver to the ear canal of the user is 20log (30/10) ≈ 9.5dB more than that of the primary receiver. Therefore, the sound pressure received by the ear hole of the user is mainly emitted by the primary receiver, and the cancellation effect of the secondary receiver is basically negligible. For far-field environment around a user, for example, at a position 50cm away from the user, distances from the primary receiver to the primary sound outlet and distances from the secondary receiver to the secondary sound outlet are substantially equal, and attenuation values of sound pressure levels emitted by the two sound emitting units are equal, so that sound pressure at the far-field position is negative superposition of the primary receiver and the secondary sound outlet, good sound wave cancellation can be realized, and sound leakage radiated to the surrounding environment is reduced.
In practical applications, the electronic device described herein may further include a processor and a memory. The memory is used for storing computer programs, and the processor is used for executing the computer programs stored by the memory so as to enable the electronic equipment to execute the electronic equipment sound production method.
The Processor may be a general-purpose Processor, and includes a Central Processing Unit (CPU), a Network Processor (NP), and the like; the Integrated Circuit may also be a Digital Signal Processor (DSP), an Application Specific Integrated Circuit (ASIC), a Field Programmable Gate Array (FPGA) or other Programmable logic device, discrete gate or transistor logic device, discrete hardware component.
The Memory may include a Random Access Memory (RAM), and may further include a non-volatile Memory (non-volatile Memory), such as at least one disk Memory.
Please refer to fig. 5, which is a flowchart illustrating a sound generating method of an electronic device according to an embodiment of the present application. As shown in fig. 5, the electronic device sound generating method according to the present application is applied to the electronic device. With reference to fig. 1 to 4, the electronic device includes: the equipment body comprises a first shell, a second shell and a frame; the first telephone receiver is arranged in the equipment body and is communicated with the first sound outlet; the second receiver is arranged in the equipment body and is communicated with the second sound outlet; the loudspeaker is arranged in the equipment body and is communicated with the third sound outlet; the first sound outlet hole, the second sound outlet hole and the third sound outlet hole are respectively formed in the equipment body; the method comprises the following steps: the first telephone receiver sends out first sound waves through the first sound outlet, the second telephone receiver sends out second sound waves through the second sound outlet, and the phases of the first sound waves and the second sound waves are the same or opposite.
In one embodiment, the electronic device further includes: a first audio driving unit and a second audio driving unit; the first telephone receiver is electrically connected with the first audio driving unit, the second telephone receiver is electrically connected with the second audio driving unit, and the method specifically comprises the following steps:
s51, determining the sound production mode of the electronic equipment.
S52, in a play mode of the electronic device, the first audio driving unit and the second audio driving unit emit electrical signals with the same phase, so that the phases of the first sound wave and the second sound wave are the same.
S53, in the non-play mode of the electronic device, the first audio driving unit and the second audio driving unit emit electric signals with opposite phases, so that the phases of the first sound wave and the second sound wave are opposite.
In one embodiment, the electronic device further includes: a speaker and a third sound outlet; the loudspeaker is arranged in the equipment body, the third sound outlet is formed in the lower part or the bottom side of the surface of the equipment body and communicated with the loudspeaker, and the loudspeaker emits third sound waves through the third sound outlet.
In one embodiment, the first receiver is disposed on the upper portion of the device body.
In an embodiment, the first sound outlet is opened at an upper central position of the surface of the device body.
In an embodiment, a distance between the first sound emitting hole and the second sound emitting hole is within a predetermined distance range.
In an embodiment, the predetermined distance range is determined by the specifications of the first receiver and the second receiver and the in-ear sound pressure.
In an embodiment, a distance between the first sound emitting hole and a first ear hole of the electronic device user is a first distance, a distance between the third sound emitting hole and a second ear hole of the electronic device user is a second distance, wherein the first ear hole is an ear hole close to the first sound emitting hole, the second ear hole is an ear hole close to the third sound emitting hole, and 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 of the first ear hole is close to the sound pressure of the second ear hole.
Specifically, the preset distance range may actually refer to a distance between the sound outlet of the first receiver and the sound outlet of the second receiver. When the distance between the two sound outlet holes is smaller, the sound leakage amount leaking to the outside is smaller, but the negative effect of reducing the sound pressure entering the ear of a user is generated; when the distance between the two sound outlet holes is set to be larger, the influence on the sound pressure entering the ear of the user is smaller, but the sound leakage amount to the outside is also increased. Therefore, for the main receiver and the auxiliary receiver with better acoustic performance, the distance between the two sound outlet holes can be properly reduced, so that although the sound pressure in the ear of a user is weakened, the original performance of the receiver is higher, and higher sound pressure in the ear can still be kept; for the main receiver and the auxiliary receiver with poor acoustic performance, in order to ensure that the sound pressure entering the ear of a user is not too small, the distance between the two sound outlet holes needs to be increased properly.
In an embodiment, the sound pressure amplitudes of the first sound wave emitted by the first receiver through the first sound emitting hole and the second sound wave emitted by the second receiver through the second sound emitting hole are equal.
In an embodiment, the second sound outlet is provided at a central position of the back of the device body, and a central axis of the second sound outlet and a central axis of the first sound outlet are located on the same vertical plane.

The principle of the electronic device sound production method described in the present application corresponds to the electronic device one-to-one, and the electronic device described in the present application can implement the electronic device sound production method described in the present application, but the implementation apparatus of the electronic device sound production method described in the present application includes, but is not limited to, the structure of the electronic device listed in this embodiment, and all structural modifications and replacements in the prior art made according to the principle of the present application are included in the protection scope of the present application.
In summary, the electronic device and the sound generating method of the electronic device in the present application generate sound waves with the same or opposite phases through the two sound generating units, i.e., the primary receiver and the secondary receiver, installed on the device, so as to enhance or weaken the sound pressure of the far field. On one hand, in the external playing mode, the main receiver and the auxiliary receiver send sound waves with the same phase, so that the surrounding sound field can be enhanced, and the electronic equipment has a good external playing stereo effect. On the other hand, in the call mode, the main receiver and the auxiliary receiver emit sound waves with opposite phases, so that the surrounding sound field can be weakened, the sound leakage amount around the user is reduced, and the call privacy is improved. Meanwhile, due to the fact that the distance between the main sound outlet hole communicated with the main receiver and the distance between the auxiliary sound outlet hole communicated with the auxiliary receiver and the ear hole of the user are different, sound waves received by the user are mainly emitted by the main receiver, the offset of the auxiliary receiver to the sound pressure entering the ear of the user is small, and the influence of the auxiliary receiver on the sound pressure entering the ear of the user can be even ignored by reasonably setting the acoustic specifications and the installation positions of the main receiver and the auxiliary receiver. Thus, the sound pressure of the user entering the ear is ensured to be unchanged or reduced a little, but the surrounding sound pressure is obviously reduced. The acoustic experience of the user is guaranteed, meanwhile, the sound leakage is reduced, and the conversation privacy is improved.
The above embodiments are merely illustrative of the principles and utilities of the present application and are not intended to limit the application. Any person skilled in the art can modify or change the above-described embodiments without departing from the spirit and scope of the present application. Accordingly, it is intended that all equivalent modifications or changes which may be made by those skilled in the art without departing from the spirit and technical spirit of the present disclosure be covered by the claims of the present application.
