In a first aspect, an embodiment of the present application first provides an electronic device, where the electronic device can reduce wind noise and improve a call experience of a user. The electronic device may also be referred to as a terminal device or terminal. The electronic device includes, but is not limited to, a handheld device, an in-vehicle device, a wearable device, a computing device, or other processing device connected to a wireless modem. For example, the electronic device may include a headset (earphone), a smart phone (smart phone), a Personal Digital Assistant (PDA) computer, a tablet computer, a laptop computer (laptop computer), a car computer, a smart watch (smart watch), a smart bracelet (smart watch), smart glasses (smart glasses), a pedometer (pedometer), a walkie talkie (twway radio), and other electronic devices having a voice call function.

The electronic equipment can be suitable for various call scenes. For example, call scenarios include, but are not limited to, indoor call scenarios, outdoor call scenarios, and in-vehicle call scenarios. The call scenes may include quiet call scenes, noisy call scenes (e.g., scenes in streets, shopping malls, airports, stations, construction sites, in the rain, at tours, concerts, etc.), riding call scenes, running call scenes, outdoor windy call scenes, monaural call scenes, binaural call scenes, and other call-enabled scenes.

In order to more conveniently illustrate the electronic device provided in the embodiments of the present application, by way of example and not limitation, the following will illustrate the technical solutions of the present application in detail by taking the electronic device as an example, which is an earphone.

The earphone (ear-set) may be a pair of converting units for receiving electrical signals from a media player or a receiver and converting the electrical signals into audible sound waves by using a speaker near the ear. The earphones may be classified into in-ear earphones, head earphones, ear earphones, and the like according to the wearing manner.

The headset may be generally classified into a wired headset (wired headset) and a wireless headset (wireless headset). The wired earphone is provided with two earphones and a connecting wire, wherein the left earphone and the right earphone are connected through the connecting wire. The wired headset may be inconvenient to wear and needs to be connected with the terminal device through a headset jack, and the electric quantity of the terminal device needs to be consumed in the working process. The wireless earphone can communicate with the terminal device by using a wireless communication technology (such as a Bluetooth technology, an infrared radio frequency technology, a 2.4G wireless technology, ultrasonic waves and the like), and compared with the wired earphone, the wireless earphone is more convenient and rapid to use due to the fact that the wireless earphone is free from the constraint of physical wires. Wherein, the left earphone of wireless earphone can pass through bluetooth connection right earphone.

Bluetooth is a low-cost large-capacity short interval wireless communication standard, the Bluetooth standard selects microwave frequency band operation, the transmission rate can be 1 Mbyte per second, the maximum transmission interval can be 10 meters, and the transmission power can reach 100 meters after being added. With the elimination of earphone jacks in some terminal devices and the popularization and version updating of bluetooth technologies, various wireless bluetooth earphones are coming into the market, and from business type monaural bluetooth earphones for conversation scenes in the early stage, to stereo bluetooth earphones capable of supporting music playing, to true wireless bluetooth earphones which completely abandon wires, the functions of the wireless earphones are more and more abundant, and the application scenes are more and more abundant.

A true wireless bluetooth headset, also called a True Wireless Stereo (TWS) headset, completely discards the wire connection approach, including two headsets (e.g., a master headset and a slave headset). For example, when the portable terminal is used, a terminal device (also referred to as a transmitting device, such as a mobile phone, a tablet, a music player with bluetooth output, etc.) is wirelessly connected with a master earphone, and then the master earphone is connected with a slave earphone in a bluetooth wireless manner, so that real bluetooth left and right channel wireless separation use can be realized. The left earphone and the right earphone of the TWS earphone can form a stereo system through Bluetooth, and the performances of listening to songs, communicating and wearing are improved. In addition, either of the two earphones can also work alone, e.g., the master earphone can return to mono sound quality in case the master earphone is not connected to the slave earphone.

The speaker 13, which may also be referred to as a horn, is disposed in the housing with its sound emitting direction facing the front housing 1, and the sound emitted from the speaker 13 can be transmitted to the ear of the user through the sound transmission hole 4 formed in the ear cap 3. The speaker 13 is an electroacoustic transducer for converting an audio signal into an acoustic signal, and the speaker 13 may be a moving-coil speaker (or called dynamic speaker), a moving-iron speaker, a moving-iron hybrid speaker, or the like, but is not limited thereto.

The storage battery 14 is used for storing the electric energy charged from the functional interface 6 and supplying power to other electric devices (for example, the speaker 13) to drive them to operate. Alternatively, the battery 14 may be any one of a nickel cadmium battery, a lithium battery, and the like.

The microphone 15, which may also be commonly referred to as a microphone, a microphone head, a microphone core, etc., is an energy conversion device that converts an acoustic signal into an electrical signal, and a device that functions in reverse of the speaker 13 (the speaker 13 is used to convert an electrical signal into an acoustic signal).

The microphone 15 may be an electrodynamic (moving coil type, aluminum ribbon type) microphone, a capacitance type microphone, a piezoelectric (crystal type, ceramic type) microphone, an electromagnetic type microphone, a semiconductor type microphone, etc., or may be a cardioid type microphone, an acute cardioid type microphone, a hyper cardioid type microphone, a bidirectional (8-shaped) microphone, a non-directional (omnidirectional type) microphone, etc., according to the principle of transduction of the microphone.

The different sounds we hear are all produced by the slight pressure difference of the surrounding air, which can be transmitted well and really for a long distance, i.e. the sound is an invisible sound wave formed by different air pressures. The microphone 15 may convert these sound waves into a change in voltage or current by a particular mechanism, and then give the change to the processor for processing. The microphone 15 typically comprises a diaphragm, the transduction of which is premised on the sound causing vibration of the microphone diaphragm.

In an exemplary working principle of the moving-coil microphone, the vibrating diaphragm drives the coil to make a cutting magnetic induction line movement, so as to generate an electric signal. The aluminum strip type microphone uses an aluminum strip as a vibrating diaphragm, the aluminum strip is placed in a strong magnetic field, and when sound enables the aluminum strip to vibrate, the aluminum strip does cutting magnetic induction line movement, so that an electric signal is generated. The capacitance microphone uses an extremely thin metal diaphragm as one stage of a capacitor and another metal back plate (about a few tenths of millimeters) with a close distance as the other stage, so that the vibration of the diaphragm can cause the change of the capacity of the capacitor to form an electric signal.

With the development of Micro Electro Mechanical System (MEMS) technology, the microphone 15 may also be a MEMS microphone in the embodiment of the present application. Compared with the traditional microphone, the MEMS microphone has smaller volume, stronger heat resistance, vibration resistance and radio frequency interference resistance, and better pickup effect.

The wireless communication module 16 is used to enable wireless communication between the wireless headset 100 and other electronic devices (e.g., cell phones).

Further, in the present embodiment, the second sound pickup hole 18 is opened in the side wall of the functional interface 6, and communicates with the outside through the functional interface 6. The side wall of the functional interface 6 is usually hidden inside the casing, and the second sound collecting hole 18 formed in the side wall cannot be seen by a user, so that a through hole is not required to be additionally formed in the casing, the overall appearance of the wireless earphone 100 cannot be affected by the formation of the second sound collecting hole 18, and the overall performance of the wireless earphone 100 is further improved.

Alternatively, the air flow may enter the communication passage 21 from the first sound pickup aperture 7 and then exit from the second sound pickup aperture 18.

Alternatively, the air flow may enter the communication passage 21 from the second sound pickup aperture 18 and then exit from the first sound pickup aperture 7.

In the embodiment of the present application, the communication channel 21 communicates the first sound pickup hole 7 and the second sound pickup hole 18, and may communicate directly or via an intermediate medium, which is not limited in the present application.

As shown in fig. 7, in the present embodiment, the opening directions of the first sound-collecting hole 7 and the second sound-collecting hole 18 are different. Through the above arrangement, it is possible to prevent the air current from simultaneously entering the communicating channel 21 from the first sound-collecting hole 7 and the second sound-collecting hole 18, causing a problem that a large air current impacts the diaphragm of the microphone 15 to cause an excessive wind noise.

Alternatively, the first sound pickup aperture 7 and the second sound pickup aperture 18 may be the same shape or different shapes.

For example, the shapes of the first and second pickup holes 7 and 18 may be any one of a circle, an ellipse, a polygon, and a track.

For another example, the first sound pickup hole 7 may be circular, and the aperture of the first sound pickup hole 7 is 0.8-1.2 mm for normal sound pickup and no influence on the appearance of the product. Further, the aperture of the first sound pickup hole 7 may be 1.0 mm.

Alternatively, the cross-sectional shape of the communication passage 21 may be any one of a circle, an ellipse, a polygon, and a raceway type.

Alternatively, the cross-sectional shapes and sizes of the first sound pickup hole 7, the second sound pickup hole 18, and the communication passage 21 may be the same.

In the present embodiment, as shown in fig. 6 and 8, the microphone 15 communicates with the communication passage 21 through the sound inlet hole 22. The sound signal passes through the first sound-collecting hole 7 and/or the second sound-collecting hole 18, the communication channel 21, and the sound inlet hole 22 in sequence and then is transmitted to the sound hole of the microphone 15, and the diaphragm of the microphone 15 collects the sound signal.

Further, the sectional area of the sound inlet hole 22 is smaller than the sectional area of the communication passage 21. Through the arrangement, the air quantity entering the microphone 15 can be reduced, so that the influence on a microphone diaphragm is reduced, and the effect of reducing wind noise is achieved.

As shown in fig. 6 and 8, the sound inlet hole 22 is provided to be offset from the first sound pickup hole 7 and the second sound pickup hole 18. The sound inlet hole 22 is offset from the first sound-pick-up hole 7 and the second sound-pick-up hole 18, rather than directly opposite, in this way it is avoided that the air flow entering the first sound-pick-up hole 7 or the second sound-pick-up hole 18 directly impacts the diaphragm of the microphone 15, thereby further reducing wind noise.

Optionally, a center line (axis) of at least one of the first sound pickup hole 7 and the second sound pickup hole 18 is perpendicular to a center line of the sound inlet hole 22.

In the embodiment of the present application, as shown in fig. 4 to 8, the center lines of the first sound pickup hole 7 and the second sound pickup hole 18 are perpendicular to the center line of the sound inlet hole 22 (actually, the center lines of the three constitute a three-dimensional rectangular coordinate system). In other embodiments, the center line of either of the two pickup holes may be perpendicular to the center line of the sound inlet hole 22. In this way, it is avoided that the first pick-up hole 7 and/or the second pick-up hole 18 is/are directly opposite to the sound inlet hole 22, so that the air flow does not directly impact the diaphragm of the microphone 15, thereby further reducing wind noise.

As shown in fig. 9, the side wall of the function interface 6 includes a peripheral wall 6a and a top wall 6b, and the peripheral wall 6a is connected to one side of the top wall 6b and is disposed around the circumference of the top wall 6 b. The peripheral wall 6a and the top wall 6b together define a slot-like structure open at one side, in which metal terminals for electrical connection with a mating plug are provided. The second sound pickup hole 18 is opened in the peripheral wall 6 a. In other embodiments, the second sound-collecting hole 18 may be opened in the top wall 6b, which is not limited in the present application.

One end of the wind noise reducing device 20 is formed with a microphone mounting groove 25, and the microphone 15 is fixedly mounted in the microphone mounting groove 25. The bottom of the microphone mounting groove 25 communicates with the communication passage 21 through the sound inlet hole 22, and the sound hole of the microphone 15 is disposed toward the sound inlet hole 22. Thus, the sound signal can smoothly enter the sound hole of the microphone through the sound inlet hole 22, and the diaphragm of the microphone 15 picks up the sound signal.

As shown in fig. 8, a waterproof sound-transmitting membrane 28 is provided between the microphone 15 and the sound inlet hole 22.

The waterproof sound-transmitting membrane 28 can play a role of waterproof sound transmission, and by providing the waterproof sound-transmitting membrane 28, under the condition of normal sound input, on the one hand, it is possible to prevent water drops, sweat, dust, or the like from entering the sound hole of the microphone 15, and further, adverse effects are generated on the quality of the microphone. On the other hand, the waterproof sound-transmitting membrane 28 also suppresses the amount of air reaching the microphone 15 to some extent, thereby further reducing wind noise and reducing the influence on the normal sound collection of the microphone.

Optionally, the waterproof sound-transmitting membrane 28 may be air-permeable or air-impermeable, which is not limited in this application.

As shown in fig. 8, the microphone 15 is mounted on the flexible circuit board 26, a through hole is opened on the flexible circuit board 26, and the microphone 15 is communicated with the sound inlet hole 22 through the through hole, so that normal sound pickup is not affected.

Further, the flexible circuit board 26 is disposed between the microphone 15 and the waterproof sound-transmitting membrane 28, so that the waterproof sound-transmitting membrane 28 can also protect the flexible circuit board 26.

Optionally, in order to prevent the flexible circuit board 26 from bending and deforming, a metal ring 27 is further disposed on the flexible circuit board 26, in which case the metal ring 27 may be disposed on a side of the flexible circuit board 26 facing the waterproof sound-transmitting membrane 28, and the flexible circuit board 26 is connected to the waterproof sound-transmitting membrane 28 through the metal ring 27.

At this time, due to the existence of the right portion of the second communicating channel 21b, the air flow can be better buffered, the pressure and the flow speed of the wind are effectively reduced, and the effect of reducing the wind noise is further achieved.

Alternatively, the wind noise reduction device 20 may be manufactured by an integral molding process.

For example, the integral molding process may be injection molding, but is not limited thereto. In this way, the processing and manufacturing difficulty is reduced, and the device is ensured to have enough mechanical strength.

Alternatively, the wind noise reduction device 20 may be made of a silicone or rubber material. Silica gel and rubber have great elasticity, can absorb the energy of wind more effectively to further reach the effect that reduces wind and make an uproar.

According to the wireless earphone 100 provided by the embodiment of the application, the air noise reduction device 20 is arranged, so that the pressure of air can be effectively relieved, a large amount of air flow can be prevented from entering the microphone 15, the influence on the diaphragm of the microphone is reduced, and the effect of reducing the air noise is achieved. According to the method and the device, the wind noise is reduced by arranging the wind noise reducing device 20, and the high specification requirements on the digital noise reduction and noise reduction algorithm processing capacity of the rear-end processor can be reduced. According to results of software simulation and actual test, the wind noise reduction performance of the wireless earphone 100 is very obvious, and the pure wind noise reduction performance benefit is about 2-5 dB.

In terms of software simulation, with a conventional wireless headset (hereinafter referred to as a conventional headset) having a pickup hole directly connected to a microphone hole as a comparison object, under the same air volume, a wind pressure value at the microphone diaphragm of the conventional headset is measured to be 33.5Pa, whereas a wind pressure value at the microphone diaphragm of the wireless headset 100 provided by the present application is measured to be 20.5Pa, which is expected to be optimized by about 20 × log10(33.5/20.5) to 4.3dB at maximum, that is, the wind noise effect reduction gain is 4.3dB at maximum.

In the aspect of practical test, the existing earphone is still used as a comparison object, and under different wearing scenes (the wearing angles are respectively 30 degrees, 60 degrees and 90 degrees), the wind noise reduction yield is about 2-5 dB, and the yield is obvious.

The third sound pickup hole 30 communicates with the first sound pickup hole 7, the sound inlet hole 22, and the second sound pickup hole 18 through the communication passage 21, respectively. At this time, the sound signal may reach the microphone 15 through the third sound pickup hole 30 and the communication passage 21 to achieve the pickup of the sound. Compared with the prior art, the wind noise reduction device has the advantages that the wind noise reduction device can better relieve wind by additionally arranging the sound pickup hole, and has a better wind noise reduction effect.

Alternatively, the air flow may enter the communication channel 21 from any one of the first pick-up sound hole 7, the second pick-up sound hole 18, and the third pick-up sound hole 30, and then flow out from the other two pick-up sound holes.

Alternatively, the air flow may enter the communication channel 21 from any one of the first pick-up hole 7, the second pick-up hole 18 and the third pick-up hole 30 and then flow out from any one of the other two pick-up holes.

For example, the air flow can flow from the third sound pickup hole 30 into the communication passage 21 and then flow out from the second sound pickup hole 18 without passing through the first sound pickup hole 7.

Similarly, the relative sizes and the cross-sectional shapes of the cross-sectional areas of the first sound pickup hole 7, the second sound pickup hole 18 and the third sound pickup hole 30 are not limited in the present application.

Alternatively, the cross-sectional shapes and sizes of the first pick-up hole 7, the second pick-up hole 18, and the third pick-up hole 30 may be the same.

As shown in fig. 12 and 13, in the present embodiment, the first sound-collecting hole 7, the second sound-collecting hole 18, and the third sound-collecting hole 30 are oriented differently from each other. Through the arrangement, at least one sound pickup hole in the three sound pickup holes can be used as an exhaust hole to exhaust air flow, and the air flow cannot be used as an air inlet hole. So that the problem of excessive wind noise caused by the impact of larger air flow on the diaphragm of the microphone 15 can be avoided.

Specifically, in fig. 12 and 13, the opening of the first pickup hole 7 faces downward in the drawing, the opening of the second pickup hole 18 faces leftward in the drawing, the opening of the third pickup hole 30 faces rightward in the drawing, and the openings of the three face differently. The first sound pickup hole 7 is perpendicular to the second sound pickup hole 18 and the third sound pickup hole 30, respectively, and the second sound pickup hole 18 and the third sound pickup hole 30 are opposite in orientation and are arranged opposite to each other.

According to results of software simulation and actual test, the wind noise reduction performance of the wireless headset 100 provided by the embodiment is very obvious, and the pure wind noise reduction performance gain is about 3-4 dB.

In terms of software simulation, the existing earphone is used as a comparison object, and under the same air volume, the air pressure value at the microphone diaphragm of the existing earphone is measured to be 33.5, while the air pressure value at the microphone diaphragm of the wireless earphone 100 provided by the present application is 22.5, the maximum optimizable value is about 20 × log10(33.5/22.5) ═ 3.5dB, that is, the wind noise influence reduction gain is 3.5dB at most.

In the aspect of practical test, the existing earphone is still used as a comparison object, and under different wearing scenes (the wearing angles are respectively 30 degrees, 60 degrees and 90 degrees), the wind noise reduction yield is about 3-4 dB, and the yield is obvious.

At this time, the communication passage 21 is linear, and the communication passage 21 and the sound inlet hole 22 are integrally formed in a "T" shape.

The center lines of the first sound pickup hole 7 and the second sound pickup hole 18 are perpendicular to the center line of the sound inlet hole 22. It is avoided that the first pick-up hole 7 and the second pick-up hole 18 are directly opposite to the sound inlet hole 22 so that the air flow does not directly impact the diaphragm of the microphone 15, thereby further reducing the wind noise.

In this embodiment, the communicating channel 21 is straight and has no bend, and the air flow entering the channel can flow out quickly.

For example, the air flow may enter the communication passage 21 from the first sound pickup aperture 7 and then quickly exit the second sound pickup aperture 18.

As another example, the air flow may enter the communication passage 21 from the second sound pickup aperture 18 and then quickly exit the first sound pickup aperture 7.

As shown in fig. 14 and 15, in the present embodiment, the orientations of the first sound pickup hole 7 and the second sound pickup hole 18 are different. Through the above arrangement, it is possible to prevent the air current from simultaneously entering the communicating channel 21 from the first sound-collecting hole 7 and the second sound-collecting hole 18, causing a problem that a large air current impacts the diaphragm of the microphone 15 to cause an excessive wind noise.

According to results of software simulation and actual test, the wind noise reduction performance of the wireless headset 100 provided by the embodiment is very obvious, and the pure wind noise reduction performance gain is about 2-5 dB.

In terms of software simulation, the existing earphone is used as a comparison object, and under the same air volume, the air pressure value at the microphone diaphragm of the existing earphone is measured to be 33.5Pa, while the air pressure value at the microphone diaphragm of the wireless earphone 100 provided by the present application is 10.5Pa, and it is expected that the maximum optimizable value is about 20 × log10(33.5/10.5) ═ 10.1dB, that is, the wind noise influence reduction gain is 10.1dB at most.

In the aspect of practical test, the existing earphone is still used as a comparison object, and under different wearing scenes (the wearing angles are respectively 30 degrees, 60 degrees and 90 degrees), the wind noise reduction yield is about 4-7 dB, and the yield is obvious.
