Description

Technical Field

[0001] The present application belongs to the technical field of electronic equipment, and specifically relates to a headset. Background Art

[0002] To ensure the quality of sound while avoiding interference from the surrounding environment, more and more users prefer to listen to music and watch videos through headphones. Headphones usually have a single sound unit that simultaneously plays high-frequency, low-frequency, and mid-frequency sound sources.

[0003] In the prior art, a sound-generating unit comprises a vibration system and a magnetic circuit system with a magnetic gap. The vibration system includes a diaphragm and a voice coil inserted into the magnetic gap to drive the diaphragm's vibrations. The sound-generating unit is tailored to reproduce high-, low-, and mid-frequency sound sources by varying the thickness of the voice coil, the thickness of the diaphragm, and the strength of the magnetic field within the magnetic gap. However, it is difficult for the same sound-generating unit to produce a combination of high, medium, and low-frequency sound effects. Furthermore, the high-frequency and low-frequency vibrations produced by the same sound-generating unit can interfere with each other, resulting in a mixed and unclear sound quality, which affects the user's listening experience. Summary of the Invention

[0004] The present application aims to provide a headset that can solve the problems of mixed tones and poor sound quality in headphones.

[0005] In order to solve the above technical problems, this application is implemented as follows:

[0006] The present application provides an earphone, comprising:

[0007] a housing, wherein a sound outlet is provided on the housing;

[0008] A first sound-emitting monomer and a second sound-emitting monomer, wherein the first sound-emitting monomer and the second sound-emitting monomer are both arranged in the shell, and the sound-emitting directions of the first sound-emitting monomer and the second sound-emitting monomer are both toward the sound outlet;

[0009] a first channel and a second channel, wherein the first channel is located between the first sound-emitting monomer and the sound outlet, and the second channel is located between the second sound-emitting monomer and the sound outlet;

[0010] a shielding portion, the shielding portion being movably disposed on the first channel and the second channel;

[0011] When the first sound-emitting unit is in a sound-emitting state, the shielding part moves to a first position so that the first channel is in an open state and the second channel is in a closed state; when the second sound-emitting unit is in a sound-emitting state, the shielding part moves to a second position so that the second channel is in an open state and the first channel is in a closed state.

[0012] In the present application, the first sound unit and the second sound unit in the earphone provided by the present application can share a sound outlet, and the sound between the first sound unit and the second sound unit can be switched by the movement of the shielding part, so that the sound of the first sound unit and the second sound unit do not interfere with each other, thereby improving the sound effect of the earphone.

[0029] The following combination Figure 1 - Figure 9 The present invention describes an earphone according to an embodiment of the present application.

[0030] like Figures 1 to 5 As shown, according to some embodiments of the present application, a headset is provided, the headset comprising:

[0031] A shell body 1, a first sound-emitting unit 2, a second sound-emitting unit 3, a first channel 4, a second channel 5 and a shielding portion, the shell body 1 is provided with a sound hole 11, the first sound-emitting unit 2 and the second sound-emitting unit 3 are both arranged in the shell body 1, and the sound emission directions of the first sound-emitting unit 2 and the second sound-emitting unit 3 are both toward the sound hole 11, so that the sounds of the first sound-emitting unit 2 and the second sound-emitting unit 3 can be transmitted to the outside from the sound hole 11, thereby ensuring the sound effect of the earphones.

[0032] See also Figure 2 The first channel 4 is located between the first sound-emitting monomer 2 and the sound-emitting hole 11, that is, the sound emitted by the first sound-emitting monomer 2 can be transmitted to the sound-emitting hole 11 through the first channel 4; the second channel 5 is located between the second sound-emitting monomer 3 and the sound-emitting hole 11, that is, the sound emitted by the second sound-emitting monomer 3 can be transmitted to the sound-emitting hole 11 through the second channel 5. The blocking portion is movably provided on the first channel and the second channel, and the blocking portion can flexibly adjust the switch state of the first channel and the second channel, so that the switch state of the first channel and the second channel matches the sounding and non-sounding states of the first sound-emitting monomer 2 and the second sound-emitting monomer 3, thereby ensuring the flexibility and independence of the first sound-emitting monomer 2 and the second sound-emitting monomer 3 in emitting sound to the outside.

[0033] See also Figure 4 When the first sounding unit 2 is in the sounding state, the shielding part moves to the first position, so that the first channel 4 is in the open state and the second channel 5 is in the closed state. For example, the sounding action of the first sounding unit 2 can be linked to the movement of the shielding part. When the first sounding unit 2 is sounding, the shielding part can be moved to the first position.

[0034] When the shielding part moves to the first position, the shielding part can open the first channel 4 so that the first channel 4 is in an open state. At this time, the closed state of the second channel 5 can be due to the fact that the second channel 5 is closed by the shielding part while the shielding part moves to the first position, or the second channel 5 is already in a closed state before the shielding part moves to the first position, and the second channel 5 can only be opened when the shielding part moves to the second position, for example, by controlling the switching state of the second channel 5 through a diaphragm with a gap.

[0035] In one embodiment, when the first sounding unit 2 is in a sounding state, the first channel 4 can be in an open state. In another embodiment, when the first sounding unit 2 is in a non-sounding state, the first channel 4 can be in a closed state. The opening of the first channel 4 when the first sounding unit 2 is in a sounding state can be based on the sound pressure airflow caused by the vibration of the diaphragm in the first sounding unit 2 pushing the shielding part to the first position, at which time the shielding part can open the first channel 4; or the circuit board in the earphone controls the movement of the shielding part according to the sounding state of the first sounding unit 2, so that the first channel 4 is opened when the shielding part moves to the first position.

[0036] See also Figure 2 When the second sound-emitting unit 3 is in the sounding state, the shielding part moves to the second position, so that the second channel 5 is in the open state and the first channel 4 is in the closed state. For example, the sound-emitting action of the second sound-emitting unit 3 can be linked to the movement of the shielding part. When the second sound-emitting unit 3 is sounding, the shielding part can be moved to the second position.

[0037] In one embodiment, when the second sounding monomer 3 is in a sounding state, the second channel 5 can be in an open state. In another embodiment, when the second sounding monomer 3 is in a non-sounding state, the second channel 5 can be in a closed state. The opening of the second channel 5 when the second sounding monomer 3 is in a sounding state can be based on the sound pressure airflow brought by the vibration of the diaphragm in the second sounding monomer 3 pushing the shielding part to the second position, at which time the shielding part can open the second channel 5. Alternatively, the circuit board in the earphone controls the movement of the shielding part according to the sounding state of the second sounding monomer 3, so that the second channel 5 is opened when the shielding part moves to the first position.

[0038] The first sound unit 2 and the second sound unit 3 in the earphones provided in the present application can share the sound outlet 11, and the sound between the first sound unit 2 and the second sound unit 3 can be switched by the movement of the shielding part, so that the sound of the first sound unit 2 and the second sound unit 3 do not interfere with each other, the first sound unit 2 and the second sound unit 3 can each have an efficient sound frequency band, and the first sound unit 2 and the second sound unit 3 can take into account the high, medium and low frequency sound effects while simplifying their respective structures, so that the earphones can be made smaller while outputting high-quality high, medium and low frequency sound segments in all directions, thereby improving the sound effect of the earphones.

[0039] Optionally, the first sound-emitting unit 2 and the second sound-emitting unit 3 do not emit sound at the same time.

[0040] Specifically, the first sounding unit 2 and the second sounding unit 3 can each have an efficient sounding frequency band. For example, the first sounding unit 2 can be a MEMS speaker with good high-frequency sound effects, and the second sounding unit 3 can be a dynamic speaker with good medium and low-frequency sound effects. This allows the combination of the first sounding unit 2 and the second sounding unit 3 to take into account the sound effects of high, medium and low frequencies. Moreover, when the earphones need to produce sound in different frequency bands, the first sounding unit 2 or the second sounding unit 3 can be flexibly selected to produce sound, so as to give full play to the sound effects of the first sounding unit 2 and the second sounding unit 3 and ensure the sound effect of the earphones.

[0041] Alternatively, see Figure 2 , the first channel 4 includes a first through hole 41, the second channel 5 includes a second through hole 51, and the shielding portion includes a first shielding portion 42 cooperating with the first through hole 41 and a second shielding portion 52 cooperating with the second through hole 51;

[0042] When the first sounding unit 2 is in a sounding state, the first blocking portion 42 releases the seal on the first through hole 41 to open the first channel 4, and the second blocking portion 52 seals the second through hole 51 to close the second channel 5.

[0043] When the second sound-emitting unit 3 is in a sound-emitting state, the second blocking portion 52 releases the seal on the second through hole 51 to open the second channel 5 , and the first blocking portion 42 seals the first through hole 41 to close the first channel 4 .

[0044] Specifically, the first shielding portion 42 releases the seal of the first through hole 41 by the sound pressure generated when the first sound unit 2 is in a sounding state, which pushes the first shielding portion 42 away from the first through hole 41, or the first shielding portion 42 moves in a direction away from the first through hole 41 under the control of a control component such as a circuit board in the earphone; at the same time, the second shielding portion 52 forms a seal on the second through hole 51 by the disappearance of the sound pressure when the second sound unit 3 is not making a sound, which causes the second shielding portion 52 to approach the second through hole 51, or the second shielding portion 52 moves in a direction close to the second through hole 51 under the control of a control component such as a circuit board in the earphone.

[0045] Similarly, the second shielding portion 52 may release the seal on the second through hole 51 by the sound pressure generated when the second sound unit 3 is in the sounding state to push the second shielding portion 52 away from the second through hole 51, or the second shielding portion 52 may move in the direction away from the second through hole 51 under the control of the control components such as the circuit board in the earphone; at the same time, the first shielding portion 42 may seal the first through hole 41 by the disappearance of the sound pressure when the first sound unit 2 is not making a sound, so that the first shielding portion 42 is close to the first through hole 41, or the first shielding portion 42 may move in the direction close to the first through hole 41 under the control of the control components such as the circuit board in the earphone, so as to ensure the independent sound of the first sound unit 2 and the second sound unit 3 in the earphone, thereby improving the sound effect of the earphone.

[0046] In one embodiment, the first shielding portion 42 and the second shielding portion 52 can be molded together to form a shielding portion of an integral structure. When the first sound-emitting unit 2 is in a sounding state, the air pressure in the first channel drives the shielding portion to move to the first position, so that the first shielding portion 42 releases the seal on the first through hole 41, and the second shielding portion 52 forms a seal on the second through hole 51; that is, when the shielding portion moves to the first position, the first shielding portion 42 moves away from the first through hole 41 and releases the seal on the first through hole 41, while the second shielding portion 52 approaches the second through hole 51 and forms a seal on the second through hole 51.

[0047] When the second sound-emitting unit 3 is in the sounding state, the air pressure in the second channel drives the shielding portion to move to the second position, so that the second shielding portion 52 releases the seal on the second through-hole 51, and the first shielding portion 42 forms a seal on the first through-hole 41. In other words, when the shielding portion moves to the second position, the second shielding portion 52 moves away from the second through-hole 51 and releases the seal on the second through-hole 51, while the first shielding portion 42 moves closer to the first through-hole 41 and forms a seal on the first through-hole 41, thereby improving the flexibility of the shielding portion in adjusting the opening and closing states of the first through-hole 41 and the second through-hole 51.

[0048] Alternatively, see Figure 3 , a first magnetic member 411 is provided on the first through hole 41, and a second magnetic member 421 that is magnetically coupled with the first magnetic member 411 is provided on the first shielding portion 42;

[0049] The second through hole 51 is provided with a third magnetic member 511 , and the second shielding portion 52 is provided with a fourth magnetic member 521 that is magnetically coupled with the third magnetic member 511 ;

[0050] When the first sound-emitting unit 2 is in a sounding state, the shielding portion moves to the first position, and the third magnetic member 511 and the fourth magnetic member 521 are magnetically connected;

[0051] When the second sound-emitting unit 3 is in a sound-emitting state, the shielding portion moves to the second position, and the first magnetic member 411 and the second magnetic member 421 are magnetically connected.

[0052] Specifically, when the shielding portion moves to the second position, the first shielding portion 42 can approach the first through hole 41 and form a seal with the first through hole 41. To improve the sealing effect of the first shielding portion 42 on the first through hole 41, the first shielding portion 42 can be tightly attached to the first through hole 41 and block the first through hole 41. The magnetic attraction between the first magnetic member 411 and the second magnetic member 421 can make the first shielding portion 42 tightly attached to the first through hole 41, ensuring the sealing of the first channel 4 when it is closed by the first shielding portion 42.

[0053] Similarly, when the shielding portion moves to the first position, the second shielding portion 52 can approach the second through hole 51 and form a seal with the second through hole 51. To improve the sealing effect of the second shielding portion 52 on the second through hole 51, the second shielding portion 52 can be tightly attached to the second through hole 51 and block the second through hole 51. The magnetic attraction between the third magnetic member 511 and the fourth magnetic member 521 can make the second shielding portion 52 tightly attached to the second through hole 51, ensuring the sealing of the second channel 5 when it is closed by the second shielding portion 52.

[0054] Specifically, the first magnetic part 411 is a first iron sheet, and the second magnetic part 421 is a first magnet, so that when the first iron sheet and the first magnet are close to each other, no matter which pole of the first magnet is close to the first iron sheet, the first iron sheet and the first magnet can be magnetically attracted to each other, thereby ensuring the sealing of the first channel 4 when it is closed.

[0055] The third magnetic part 511 is a second iron sheet, and the fourth magnetic part 521 is a second magnet, so that when the second iron sheet and the second magnet are close to each other, no matter which pole of the second magnet is close to the second iron sheet, the second iron sheet and the second magnet can be magnetically attracted to each other, thereby ensuring the sealing of the second channel 5 when it is closed.

[0056] In addition, the first magnetic member 411 and the second magnetic member 421 may also be magnets in cooperation with each other. When the first magnetic member 411 and the second magnetic member 421 are close to each other, the ends with opposite polarities fit together, which can also ensure the sealing of the first channel 4 when it is closed; and the third magnetic member 511 and the fourth magnetic member 521 may also be magnets in cooperation with each other. When the third magnetic member 511 and the fourth magnetic member 521 are close to each other, the ends with opposite polarities fit together, which can also ensure the sealing of the second channel 5 when it is closed.

[0057] Optionally, the first shielding portion 42 is a first elastic diaphragm provided on the first through hole 41, and a first slit is provided on the first elastic diaphragm; the second shielding portion 52 is a second elastic diaphragm provided on the second through hole 51, and a second slit is provided on the second elastic diaphragm;

[0058] When the first sound-emitting unit 2 is in a sound-emitting state, the first gap is opened and the second gap is closed; when the second sound-emitting unit 3 is in a sound-emitting state, the second gap is opened and the first gap is closed.

[0059] Specifically, the first slit on the first elastic diaphragm can be blown open when the pressure on one side of the first elastic diaphragm increases, and remain closed when the pressure on both sides of the first elastic diaphragm is balanced; similarly, the second slit on the second elastic diaphragm can be blown open when the pressure on one side of the second elastic diaphragm increases, and remain closed when the pressure on both sides of the second elastic diaphragm is balanced.

[0060] It can also be achieved that when the first sound unit 2 is in a sounding state, the sound pressure airflow brought about by the vibration of the diaphragm in the first sound unit 2 causes the first gap to open, while the second sound unit 3 is not making any sound at this time, and the pressure on both sides of the second elastic diaphragm is balanced, so that the second gap remains closed; when the second sound unit 3 is in a sounding state, the sound pressure airflow brought about by the vibration of the diaphragm in the second sound unit 3 causes the second gap to open, while the first sound unit 2 is not making any sound at this time, and the pressure on both sides of the first elastic diaphragm is balanced, so that the first gap remains closed.

[0061] Alternatively, see Figure 1 and Figure 2 , the first through hole 41 and the second through hole 51 are both connected to the sound outlet hole 11 through the sound outlet channel 6;

[0062] When the first sound-emitting unit 2 is in a sound-emitting state, the sound of the first sound-emitting unit 2 passes through the first through hole 41 and the sound outlet channel 6 and is output from the sound outlet hole 11; when the second sound-emitting unit 3 is in a sound-emitting state, the sound of the second sound-emitting unit 3 passes through the second through hole 51 and the sound outlet channel 6 and is output from the sound outlet hole 11.

[0063] Specifically, since the first through hole 41 and the second through hole 51 are both connected to the sound outlet hole 11 through the sound outlet channel 6, the sounds of the first sound unit 2 and the second sound unit 3 can be output from the sound outlet hole 11 through the same sound outlet channel 6 after passing through the first through hole 41 and the second through hole 51 respectively, thereby avoiding the need to set separate channels for the first sound unit 2 and the second sound unit 3, thereby simplifying the structure of the earphone.

[0064] Alternatively, see Figures 2 to 4 A rotating shaft 12 is provided in the housing 1, and the shielding portion is movably sleeved on the rotating shaft 12. The shielding portion rotates around the rotating shaft and can switch between a first position and a second position.

[0065] Specifically, when the shielding portion is movably sleeved on the rotating shaft 12 , the first shielding portion 42 and the second shielding portion 52 may be connected to each other and movably sleeved on the rotating shaft 12 .

[0066] When the first sounding unit 2 is in a sounding state, the shielding portion can rotate around the rotation axis to the first position. When the first shielding portion 42 rotates to the first position, the first through hole 41 can be released from the seal. When the second shielding portion 52 rotates to the first position following the first shielding portion 42, the second through hole 51 is sealed.

[0067] When the second sound-emitting unit 3 is in a sound-emitting state, the second shielding portion 52 can release the seal on the second through hole 51 when it is rotated to the second position, and the first shielding portion 42 forms a seal on the first through hole 41 when it follows the second shielding portion 52 to rotate to the second position.

[0068] In one embodiment, see Figure 6 and Figure 7The first shielding portion 42 and the second shielding portion 52 can be fixedly connected or integrally formed to form a through hole, and the rotating shaft 12 is passed through the through hole, so that the first shielding portion 42 and the second shielding portion 52 can rotate together relative to the rotating shaft 12, that is, when the first shielding portion 42 rotates relative to the rotating shaft 12, it can drive the second shielding portion 52 to rotate, and when the second shielding portion 52 rotates relative to the rotating shaft 12, it can drive the first shielding portion 42 to rotate.

[0069] See also Figure 4 When the first sound unit 2 is in a sounding state, the sound pressure airflow brought by the vibration of the diaphragm in the first sound unit 2 can push the first shielding part 42 to rotate. When the first shielding part 42 is rotated to the first position, it can be away from the first through hole 41, so that the first shielding part 42 releases the seal on the first through hole 41. At this time, the second shielding part 52 is close to the second through hole 51 when following the first shielding part 42 to rotate to the first position, so that the second shielding part 52 can form a seal on the second through hole 51.

[0070] See also Figure 2 When the second sound unit 3 is in the sounding state, the sound pressure airflow brought by the vibration of the diaphragm in the second sound unit 3 can push the second shielding part 52 to rotate. When the second shielding part 52 is rotated to the second position, it can be away from the second through hole 51, so that the second shielding part 52 can release the seal of the second through hole 51. At this time, the first shielding part 42 is close to the first through hole 41 when following the second shielding part 52 to rotate to the second position, so that the first shielding part 42 forms a seal on the first through hole 41, realizing that when one of the first channel 4 and the second channel 5 is opened, the other can be closed accordingly, ensuring the correspondence between the sound of the first sound unit 2 and the opening of the first channel 4, and the correspondence between the sound of the second sound unit 3 and the opening of the second channel 5, thereby ensuring the sound effect of the earphones.

[0071] Optionally, the first sound-emitting unit 2 is a MEMS speaker, and the second sound-emitting unit 3 is a dynamic speaker.

[0072] Specifically, when the first sound unit 2 is a MEMS speaker, the MEMS speaker does not need to be equipped with a magnet, but only uses the piezoelectric sound principle to vibrate the diaphragm, so that the first sound unit 2 has a higher sensitivity high-frequency extension, and the first sound unit 2 is small in size, which can achieve lightweight headphones; and when the second sound unit 3 is a dynamic speaker, the dynamic speaker has balanced high, medium and low audio frequencies, and a stronger low-frequency dive, which can provide the headphones with a better bass effect.

[0073] Optionally, the earphone further includes a circuit board, and the circuit board is used to control the first sound-emitting unit 2 or the second sound-emitting unit 3 to be in a sound-emitting state.

[0074] Specifically, the first sounding unit 2 and the second sounding unit 3 can each have an efficient sounding frequency band. For example, the first sounding unit 2 can be a MEMS speaker with good high-frequency sound effects, and the second sounding unit 3 can be a dynamic speaker with good medium and low-frequency sound effects, so that the combination of the first sounding unit 2 and the second sounding unit 3 can take into account the sound effects of high, medium and low frequencies. When the circuit board is used to control the first sounding unit 2 or the second sounding unit 3 to be in a sounding state, the earphones can flexibly select the first sounding unit 2 or the second sounding unit 3 to make sound, so as to give full play to the sound effects of the first sounding unit 2 and the second sounding unit 3 and ensure the sound effect of the earphones.

[0075] Optionally, when the earphone is used for high-frequency output, the circuit board controls the first sounding unit 2 to be in a sounding state; when the earphone is used for low-frequency and medium-frequency output, the circuit board controls the second sounding unit 3 to be in a sounding state.

[0076] Specifically, when the circuit board controls the first sound-emitting monomer 2 to be in a sound-emitting state, the diaphragm of the MEMS speaker vibrates, and the air pressure generated by the diaphragm vibration pushes the first shielding portion 42 to move, so that the first shielding portion 42 releases the seal on the first through-hole 41, ensuring that the sound of the first sound-emitting monomer 2 is transmitted to the sound outlet 11 through the first channel 4;

[0077] When the circuit board controls the second sound-emitting unit 3 to be in a sound-emitting state, the diaphragm of the dynamic speaker will vibrate, and the air pressure generated by the vibration of the diaphragm will push the second blocking part 52 to move, so that the second blocking part 52 releases the seal on the second through hole 51, ensuring that the sound of the second sound-emitting unit 3 is transmitted to the sound outlet 11 through the second channel 5, so as to realize the full-range output of high, medium and low frequency sound segments by the earphones.
