Description

Headphones with Physical Transparency Mode for External Sound

The invention relates to an earphone, in particular to an earphone that can listen to external sounds after adjustment.

Headphones are wearable devices that use speakers to convert electrical signals into sound waves. Usually, it is necessary to maintain airtightness in the ear canal and isolate external sounds to improve user experience. However, excessive isolation of external sounds, especially the popular active noise reduction or ambient noise reduction in recent years, will greatly reduce the perception of the surrounding environment, causing a certain degree of safety concerns.

At present, when some well-known headphone manufacturers develop new headphones, they have considered safety issues and designed a transparent mode that enhances external sounds. For example, turn off active noise cancellation, or use external microphones and amplifiers to send external sounds into the interior as signals, and then play them internally. However, the external sound of these methods is easy to be distorted, or it will increase the power consumption of the battery, which is not conducive to prolonging the use time of the earphone.

Aiming at the problems in the prior art, the present invention designs an earphone, which uses the transformation of physical structure to naturally send the external sound into the ear canal, and can be converted into a transparent mode in which the external sound can be heard without changing the wearing condition.

The internal magnetic unit is arranged in the structure of the mode switching element. The magnetic induction module is coupled to the speaker module. When the front audio cavity and the mode switching element rotate relative to make the magnetic induction module close to or away from the internal magnetic unit, the magnetic induction module outputs one of a speaker off signal or a speaker on signal to the speaker module.

Further, when the front sound cavity body and the mode switching element are relatively rotated until the outer sound-transmitting hole is connected to the inner sound-transmitting hole, the magnetic induction module outputs a speaker shutdown signal; the current sound cavity body and the mode switching element are relatively rotated to the mode switching.

The speaker module 1 has a sound-speaking direction side for emitting a sound from the sound-speaking direction side. The front sound cavity 2 is coupled with the speaker module 1 from the sound-speaking direction side, and the front sound cavity 2 further includes a sound guide tube 21 for receiving and conducting sound; a pipe wall of the sound guide tube 21 has at least one The inner sound-transmitting channel 20 penetrates the pipe wall. The mode switching element 3 is disposed outside the pipe wall of the sound guide pipe 21 and can rotate relative to the pipe wall. The mode switching element 3 has at least one outer sound-transmitting hole 30 penetrating the mode switching element 3 . Wherein, when the front sound cavity body 2 and the mode switching element 3 are relatively rotated until the outer sound transmission hole 30 communicates with the inner sound transmission hole 20, the sound guide tube 21 receives the sound from the outside through the outer sound transmission hole 30 and the inner sound transmission hole 20. An external sound, as shown in Figure 2; the current sound When the cavity 2 and the mode switching element 3 are relatively rotated until the mode switching element 3 blocks the inner sound-transmitting channel 20 from the outside, the mode switching element 3 blocks the external sound from entering the sound guide tube 21 , as shown in FIG. 3 .

The speaker module 1 includes a diaphragm and a circuit control element, receives electrical signals to convert them into sound waves, and sends out sound toward the ear canal and the earplugs 5 . Generally defined, the diaphragm of the speaker module 1 is the center line, the sound-emitting side is the front sound cavity 2, and the back-to-sound side is the rear sound cavity 4. The rear sound cavity 4 is closed to the front sound cavity 2, so that the speaker module 1 is located between the front sound cavity 2 and the rear sound cavity 4, and is protected in the cavity.

In this embodiment, the mode switching element 3 is annular and is sleeved outside the front sound cavity 2 . The mode switching element 3 has four outer sound-transmitting holes 30 (as shown in FIG. 4A ), and there are four sound-transmitting holes 30 on the wall of the sound guide pipe 21 .

The four outer sound-transmitting channels 30 and the four inner sound-transmitting channels 20 are substantially located on the same plane, and each outer sound-transmitting channel 30 corresponds to at least one inner sound-transmitting channel 20 . Rotating the mode switching element 3 makes the outer sound-transmitting holes 30 and the inner sound-transmitting holes 20 overlap and the air circulates. At this time, the outside sound can enter the sound guide tube 21 through the air medium, as shown in FIG. 2B . Rotating the mode switching element 3 makes the outer sound-transmitting holes 30 and the inner sound-transmitting holes 20 staggered and the air does not circulate. At this time, the external sound entering the outer sound-transmitting holes 30 is blocked by the wall of the sound guide pipe 21 , as shown in FIG. 3 .

In this embodiment, a limit hook 27 is designed on the outer surface of the front sound cavity 2 to limit the rotation angle of the mode switching element 3 . The rotation angle is between 20 and 60 degrees. For example, after turning 45 degrees clockwise, it is blocked by the limit hook 27. At this time, the outer sound-transmitting hole 30 and the inner sound-transmitting hole 20 are completely superimposed; The outer sound transmission channel 30 and the inner sound transmission channel 20 are completely staggered.

By switching the physical structure, the user can consume no extra power Hear the original sound of the outside environment. And for the user, the control is simple and intuitive, and the switching can be completed without visual assistance.

The sound transmission extension direction E of the outer sound transmission channel 30 and the sound transmission extension direction M of the sound guide tube 21 form an included angle A, and the included angle A is less than 90 degrees, so that an external sound enters the outer sound transmission channel 30 in a forward direction. Increase the volume and clarity of external sounds.

The earphone W1 with the external sound physical transmission mode further includes an internal magnetic unit 63 and a magnetic induction module 61 . The internal magnetic unit 63 is arranged in the structure of the mode switching element 3 . The magnetic induction module 61 is coupled to the speaker module 1 . When the pre-audio cavity 2 and the mode switching element 3 rotate relative to make the magnetic sensing module 61 approach or move away from the internal magnetic unit 63 , the magnetic sensing module 61 outputs either a speaker off signal or a speaker on signal to speaker module 1. The speaker off signal can completely prevent the electrical signal from being converted into sound waves, or reduce the volume; the speaker on signal can restore the corresponding electrical signal into sound waves, or restore the volume.

When the front sound cavity 2 and the mode switching element 3 rotate relative to each other until the outer sound-transmitting channel 30 is connected to the inner sound-transmitting channel 20, the magnetic induction module 61 outputs a speaker shutdown signal; the current sound cavity 2 and the mode switching element 3 are relatively opposite When the mode switching element 3 is turned to block the inner sound-transmitting channel 20 from the outside, the magnetic induction module 61 outputs a speaker-on signal. In this embodiment, the front sound cavity 2 and the mode switching element 3 are relatively rotated until the outer sound transmission channel 30 is connected to the inner sound transmission channel 20. At the same time, the magnetic induction module 61 is also close to the inner magnetic unit 63, so that the magnetic induction module 61 Output a speaker shutdown signal. The internal magnetic unit 63 can be a NdFeB magnet with no power consumption, and the magnetic induction module 61 can be a Hall sensor with extremely low power consumption. In this way, under the configuration of extremely low power consumption, the musical sound originally emitted by the speaker module 1 can be simultaneously turned off or reduced in the transparent mode, so that the external sound is clearer.

The earphone W1 with external sound physical transparency mode further includes a thin The electromagnet module 74 and an external magnetic unit 73 . The thin electromagnet module 74 is disposed on the surface of the rear sound cavity 4 in the rotation direction of the mode switching element 3 . The external magnetic unit 73 is fixed on the surface of the mode switching element 3, and is magnetically coupled with the thin electromagnet module 74, as shown in FIG. 4A . When the thin electromagnet module 74 receives a control signal, the thin electromagnet module 74 reverses the magnetic pole direction, the magnetic field drives the external magnetic unit 73 to displace, and drives the mode switching element 3 to rotate. The external magnetic unit 73 can also be an NdFeB magnet. For example, the S end of the external magnetic unit 73 is magnetically coupled with the N pole of the upper end of the thin electromagnet module 74; The S end of the thin electromagnet module 74 is repelled by the S pole at the upper end, and is attracted to the N pole at the lower end, thereby driving the mode switching element 3 to rotate. Of course, when another control signal is received, the upper and lower magnetic poles of the thin electromagnet module 74 can be reversed again to drive the mode switching element 3 to turn back.

In this embodiment, the mode switching element 3 further includes a sound-collecting cover structure 38 that communicates with the outside world and an external sound-transmitting channel 30 . The sound collecting cover structure 38 can be a tapered structure, mainly to increase the received external sound.

The structures and elements not mentioned in the second embodiment are basically the same as those of the first embodiment. The differences between the second embodiment and the first embodiment will be described in the following paragraphs.

In the earphone W2 with the external sound physical transparent mode of the second embodiment, the mode switching element 3 further includes an ear wing hook structure 39, and the ear wing hook structure 39 has a sound collecting cover structure connected to the ear wing hook structure 39. Pass through the outside and the outside sound-transmitting channel 30 . The ear wing hook structure 39 is fastened at the user's auricle and ear conch, so that the earphone W2 with the external sound physical transmission mode is more firmly attached to the user's ear. The ear wing hook structure 39 also acts as a sound collecting cover structure, which further increases the clarity of the received external sound. Therefore, the earphone W2 with the external sound physical transmission mode may have only one outer sound transmission hole 30 and a corresponding inner sound transmission hole 20 .

Since the ear wing hook structure 39 of the second embodiment makes it difficult for the mode switching element 3 to rotate, in the second embodiment, the mode switching element 3 is fixed and the rear sound cavity 4 is rotated to link the front sound cavity 2, so that the outer sound-transmitting hole is 30 and the inner sound-transmitting channel 20 are connected or staggered. Rotation makes the outer sound-transmitting holes 30 and the inner sound-transmitting holes 20 overlap and the air circulates. At this time, the outside sound can enter the sound guide tube 21 through the air medium, as shown in FIG. 6 . Rotation makes the outer sound-transmitting holes 30 and the inner sound-transmitting holes 20 staggered and the air does not circulate. At this time, the external sound entering the outer sound-transmitting holes 30 is blocked by the wall of the sound guide pipe 21 , as shown in FIG. 7 .

In this embodiment, a limit hook (not shown) is also designed to limit the rotation angle of the mode switching element 3 . The rotation angle can be between 10 degrees and 60 degrees. For example, in this embodiment, the difference between the rear sound cavity 4 (headphone cable) of FIG. 6A and the rear sound cavity 4 (headphone cable) of FIG. 7A is 43 degrees.

In this embodiment, the earphone W2 with external sound physical transparency mode may also include a thin electromagnet module and an external magnetic unit (not shown), the operation mode, means and purpose of which are the same as those of the first embodiment.

In the transparent mode as shown in FIG. 6 , when the magnetic sensing module 61 is far away from the internal magnetic unit 63 , the magnetic sensing module 61 outputs a speaker shutdown signal; in the musical sound mode as shown in FIG. 7 , the magnetic sensing module 61 is close to the internal magnetic unit 63 . When the unit 63 is turned on, the magnetic induction module 61 outputs a speaker-on signal. The means and purpose of the speaker-off signal and the speaker-on signal are the same as in the aforementioned embodiments.

In the third embodiment, the present invention further provides an earphone W3 with an external sound physical transparent mode, which includes a speaker module 1 , a front sound cavity 2 and a mode switching element 3 . The speaker module 1 is the same as the aforementioned embodiment. The front sound cavity 2 is coupled with the speaker module 1 from the sounding direction side. The front sound cavity 2 further includes a sound guide tube 21 for receiving and conducting sound. The wall of the sound guide tube 21 has an inner transparent The sound hole 20 penetrates the pipe wall. The mode switching element 3 is movably penetrated through the sound guide tube 21 through the inner sound-transmitting channel 20 . The mode switching element 3 further has an outer sound-transmitting channel 30 formed inside the mode switching element 3 and has an outer port 30E and an inner port 30I, the outer port 30E communicates with the outside world, and the inner port 30I is used for communicating with the sound guide tube 21 . When the mode switching element 3 is relatively moved to the inner port 30I and communicates with the sound guide pipe 21, the sound guide pipe 21 receives an external sound from the outside through the outer sound transmission hole 30 and the inner sound transmission hole 20, as shown in Figure 10; When the mode switching element 3 relatively moves to the point where the pipe wall blocks the inner port 30I, the pipe wall blocks the external sound from entering the sound guide pipe 21 , as shown in FIG. 9 .

The biggest difference between the third embodiment and the first embodiment and the second embodiment is that the rotation mode switching element 3 is changed to the displacement mode switching element 3, and the relative positions of the outer sound-transmitting holes 30 and the inner sound-transmitting holes 20 are changed from inside and outside to interspersed.

The mode switching element 3 in the third embodiment may be a long cylindrical shape or a long flat shape, and at least one end of the mode switching element 3 has an external port 30E that communicates with the outer sound-transmitting hole 30 . The external port 30E may be an opening facing the front of the axis of the mode switching element 3 , or an opening facing the side of the end point of the mode switching element 3 . The mode switching element 3 may further include a tapered sound collecting cover structure 38 to communicate with the outside world and the external sound transmission channel 30E.

The middle section of the mode switching element 3 has an inner port 30I that communicates with the outer sound-transmitting channel 30 . In the third embodiment, the inner port 30I is a side opening of the mode switching element 3 , so as to ensure that the inner port 30I can face the pipe wall of the sound guide pipe 21 beside the inner sound-transmitting hole 20 . When the mode switching element 3 is displaced outward so that the inner port 30I faces the pipe wall of the sound guide pipe 21 beside the inner sound-transmitting hole 20, the inner port 30I is blocked by the pipe wall, and the outer sound-transmitting hole 30 communicates with the outside world but not the sound guide pipe. 21, form the musical tone pattern of Fig. 9; When the mode switching element 3 is displaced inward and the inner port 30I penetrates into the sound guide pipe 21, the outer sound-transmitting hole 30 communicates with the outside world and the sound guide pipe 21 at the same time, forming as shown in Fig. 10 transparent mode.

In other embodiments, the inner sound-transmitting channel 20 may be a bent channel, such as a U-shaped channel. At this time, the inner port 30I is an opening facing the axis of the mode switching element 3. When the mode switching element 3 is displaced inward and is blocked by the pipe wall of the inner sound-transmitting hole 20, the outer sound-transmitting hole 30 is connected to the outside world but not connected to the sound guide pipe. 21, to form a musical tone mode; when the mode switching element 3 is displaced outward to keep a gap with the wall of the inner sound transmission hole 20, the outer sound transmission hole 30 communicates with the outside world and the sound guide pipe 21 at the same time, forming a transparent mode.

In the earphone W3 with external sound physical transparent mode of the third embodiment, if the mode switching element 3 is large in size and still occupies the inner path of the sound guide tube in the musical sound mode, a gap can be opened in the middle of the mode switching element 3 or the musical sound hole 35. In this way, in the music mode, the sound can still pass through the gap or the music hole 35 from the speaker module 1 and reach the ear canal.

The earphone W3 with external sound physical transparent mode further includes a miniature pressing unit 7 coupled to the speaker module 1 and used to interfere with the mode switching element 3. When the mode switching element 3 and the sound guide tube 21 move relative to each other, the internal port 30I is connected to the sound guide tube. At 21:00, the micro-pressing unit 7 moves away from the mode switching element 3 and outputs a speaker shutdown signal to the speaker module 1 . Conversely, when the mode switching element 3 and the sound guide tube 21 move relative to each other so that the wall of the sound guide tube 21 blocks the internal port 30I, the micro pressing unit 7 touches the mode switching element 3 and outputs a loudspeaker on signal to the speaker mode Group 1. The means and purpose of the speaker-off signal and the speaker-on signal are the same as those of the aforementioned embodiments.

In this embodiment, the earphone W3 with the external sound physical transparent mode may also include a thin electromagnet module and an external magnetic unit (not shown in the figure), and the thin electromagnet module and the mode switching element 3 are arranged in the same direction at the front Outside the sound cavity 2, the external magnetic unit is installed on the mode switching element 3 near the thin electromagnet module. When the thin electromagnet module receives the control signal to reverse the electrodes, the external magnetic unit is pulled to the other magnetic pole, and the mode switching element 3 is also pulled to move.

The external sound transmission hole in the mode switching element and the inner sound transmission hole in the sound guide tube are mutually transparent, so that the external sound can be transmitted through each other. into the sound guide tube. In addition, the relative structure of the mode switching element and the sound guide tube can be changed by rotating or pushing the displacement, so that the transparency of the external sound can be changed simply by switching. In addition, while changing the relative structure, the micro sensor in the earphone is used to trigger the opening or closing of the music sound of the speaker, so as to improve the clarity of the external sound. Finally, the simple electromagnet principle can be used to convert the signal into magnetic force to change the relative structure, so as to achieve the effect of automatically converting the external sound transmission mode.
