Description

Technical Field

[0001] This application relates to the field of headphone technology, specifically to headphone heads and over-ear headphones. Background Technology

[0002] For privacy and to avoid external interference, people often wear headphones. However, both in-ear and semi-in-ear headphones need to penetrate the auricle, inevitably causing significant fatigue during prolonged wear. Therefore, more and more people are choosing to wear over-ear headphones. Over-ear headphones consist of a headband and earpieces connected to both ends of the headband. After the headband is wrapped around the head, the earpiece housings are placed on the ears. Because the earpieces do not penetrate the auricle, fatigue is less even during extended wear.

[0003] However, because the ear is located in the ear canal and the surrounding skin of the ear seals the ear canal, the ear is prone to sweating and feeling stuffy after wearing it for a long time.

[0004] Therefore, how to solve or improve the problem of human ears easily sweating and feeling stuffy in the earphone cavity in related technologies has become an important technical problem to be solved by those skilled in the art. Utility Model Content

[0042] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0043] The following is combined Figures 1 to 8 This describes an embodiment of the present application.

[0044] According to embodiments of this application, in one aspect, an earphone head is provided, such as... Figure 1 and Figure 2 As shown, it includes a housing 1, a sound-generating unit 2, earmuffs 3, and a ventilation unit 4. The sound-generating unit 2 is disposed inside the housing 1 and is used to emit sound.

[0045] An air intake channel is provided inside the housing 1, and an air outlet 121 is provided on the housing 1. The outer end of the air outlet 121 penetrates the outer wall of the housing 1, and the inner end of the air outlet 121 is connected to the air intake channel, so that the airflow in the air intake channel can be discharged outside the housing 1 through the air outlet 121.

[0046] The earcup 3 is connected to the housing 1 and is provided with a receiving groove 311 for accommodating the ear. An air intake channel communicates with the receiving groove 311, allowing airflow within the receiving groove 311 to enter the air intake channel. A first air hole 312 is provided through the earcup 3, penetrating both the outer wall of the earcup 3 and the inner wall of the receiving groove 311.

[0047] A first air hole 312 is provided through the ear cup 3, so that one end of the first air hole 312 penetrates the outer wall of the ear cup 3 and the other end penetrates the inner wall of the receiving groove 311, thereby the first air hole 312 is connected to the receiving groove 311, and outside air can enter the receiving groove 311 through the first air hole 312.

[0048] The exhaust unit 4 is installed inside the air outlet 121 and can discharge the gas inside the air outlet 121 to the outside.

[0049] When using this headset, the user inserts their ear into the receiving slot 311 on the earcup 3 to hear the sound emitted by the sound-producing unit 2. At the same time, the exhaust unit 4 is activated, continuously expelling the gas in the vent 121 to the outside, creating a negative pressure inside the vent 121. Since the first vent 312, the receiving slot 311, the air inlet channel, and the vent 121 are connected in sequence, under the action of the exhaust unit 4, air enters from the first vent 312, then flows through the receiving slot 311 and the air inlet channel in sequence, and finally exits from the vent 121.

[0050] In this way, under the continuous action of the exhaust unit 4, airflow is continuously generated in the receiving slot 311 to dissipate heat and prevent the user's ears from sweating and feeling stuffy in the receiving slot 311.

[0051] Meanwhile, under the continuous action of the exhaust unit 4, airflow is continuously generated in the air intake channel. The air flowing in the air intake channel can exchange heat with the sound unit 2 to dissipate heat from the sound unit 2 and prevent the sound unit 2 from overheating and affecting normal use.

[0052] The sound-generating unit 2 can be a loudspeaker or a piezoelectric sound-generating element, etc. The exhaust unit 4 can be a fan or a blower.

[0053] In optional embodiments, such as Figure 1 and Figure 3 As shown, multiple first air holes 312 are provided, and each first air hole 312 is evenly arranged along the circumference of the earcup 3, that is, each first air hole 312 is arranged sequentially along the circumference of the earcup 3.

[0054] After the exhaust unit 4 is activated, under the action of negative pressure, the outside air flows into the receiving tank 311 through each of the first air holes 312, which makes the airflow in the receiving tank 311 larger and the heat dissipation effect better.

[0055] As an optional embodiment, such as Figure 2 As shown, housing 1 includes mounting housing 11 and outer housing 12. Sound unit 2 is mounted on mounting housing 11, and earcups 3 are connected to mounting housing 11.

[0056] The outer shell 12 is connected to the mounting shell 11, forming a flow cavity 122 between the outer shell 12 and the mounting shell 11. An air intake channel is formed on the mounting shell 11 and communicates with the flow cavity 122. When the earmuff 3 is connected to the mounting shell 11, the receiving groove 311 communicates with the flow cavity 122 through the air intake channel. An air outlet 121 is formed on the outer shell 12, such that one end of the air outlet 121 penetrates the inner wall of the flow cavity 122 and the other end penetrates the outer wall of the outer shell 12, thereby allowing the flow cavity 122 to communicate with the outside through the air outlet 121.

[0057] Thus, after the exhaust unit 4 is activated, under negative pressure, outside air flows into the receiving tank 311 through the first air hole 312. Since the receiving tank 311 is connected to the flow cavity 122 through the air inlet channel, and the flow cavity 122 is connected to the outside through the air outlet 121, the airflow flowing into the receiving tank 311 enters the flow cavity 122 through the air inlet channel, and then flows from the flow cavity 122 to the outside through the air outlet 121.

[0058] Under the continuous action of the exhaust unit 4, the airflow continuously flows through the air intake channel, thereby exchanging heat with the mounting housing 11, and then with the exhaust unit 4 installed on the mounting housing 11. This continuously dissipates heat from the exhaust unit 4, preventing it from overheating and affecting normal operation.

[0059] Furthermore, since the earcups 3 are connected to the mounting shell 11, under the continuous action of the exhaust unit 4, the airflow continuously flows through the receiving groove 311 and can also be used for heat exchange in the mounting shell 11, thereby dissipating heat from the exhaust unit 4.

[0060] Furthermore, since a flow cavity 122 is formed between the outer shell 12 and the mounting shell 11, under the continuous action of the exhaust unit 4, the airflow continuously flows through the flow cavity 122 and can also be used for heat exchange in the mounting shell 11, thereby dissipating heat from the exhaust unit 4.

[0061] In optional embodiments, such as Figure 2 As shown, the mounting housing 11 includes a base housing 111 and a cover housing 112. The sound-generating unit 2 is mounted on the base housing 111, and the cover housing 112 covers the housing, forming a mounting cavity between the cover housing 112 and the base housing 111, and placing the sound-generating unit 2 within the mounting cavity. The outer shell 12 is connected to the side of the cover housing 112 away from the housing, forming a flow cavity 122 between the outer shell 12 and the cover housing 112.

[0062] Thus, after the exhaust unit 4 is activated, the airflow flows within the flow cavity 122 under negative pressure. Since the sound-generating unit 2 is located within the mounting cavity, and the mounting cavity and the flow cavity 122 are separated by the cover 112, the sound-generating unit 2 is isolated from the airflow within the flow cavity 122 by the cover 112. When the airflow flows within the flow cavity 122, it does not come into contact with the sound-generating unit 2, thereby preventing the airflow from affecting the sound output of the sound-generating unit 2.

[0063] The air intake channel may include two parts respectively disposed on the base shell 111 and the cover shell 112. When the base shell 111 and the cover shell 112 are connected, the two parts are combined to form the air intake channel.

[0064] In a further embodiment, such as Figures 4 to 7 As shown, the base shell 111 has a second vent 1111 and an annular groove 1112. One end of the second vent 1111 penetrates the side of the base shell 111 away from the cover shell 112, and the other end communicates with the annular groove 1112. When the earcup 3 is connected to the side of the base shell 111 away from the cover shell 112, the receiving cavity on the earcup 3 communicates with the second vent 1111.

[0065] The opening of the annular groove 1112 penetrates the base shell 111 on the side near the cover shell 112, and a third vent 1121 is provided through the cover shell 112. After the cover shell 112 is connected to the base shell 111 and the outer shell 12 is connected to the cover shell 112, one end of the third vent 1121 communicates with the annular groove 1112, and the other end communicates with the flow cavity 122.

[0066] Thus, the second vent 1111, the annular groove 1112, and the third vent 1121 are connected in sequence to form an air intake channel. After the exhaust unit 4 is started, under the action of negative pressure, the airflow flows from the receiving cavity to the second vent 1111, then flows through the annular groove 1112 and the third vent 1121 in sequence before entering the flow cavity 122, and then is discharged to the outside through the exhaust port 121, forming a continuous airflow.

[0067] Since the annular groove 1112 can accommodate gas, it allows the airflow to flow more smoothly into the flow cavity 122, thereby increasing the air volume flowing in the flow cavity 122 and improving the heat dissipation effect.

[0068] In optional implementations, such as Figure 4 As shown, multiple second air holes 1111 are provided, and each second air hole 1111 is evenly arranged along the circumference of the annular groove 1112, that is, each second air hole 1111 is arranged sequentially along the circumference of the annular groove 1112.

[0069] After the exhaust unit 4 is activated, under the action of negative pressure, the airflow in the receiving groove 311 can enter the annular groove 1112 from each of the second air holes 1111. This results in a larger airflow volume entering the annular groove 1112, which in turn increases the airflow volume entering the flow cavity 122 through the third air hole 1121, leading to better heat dissipation.

[0070] In optional implementations, such as Figure 5 As shown, multiple third air holes 1121 are provided, and each third air hole 1121 is evenly arranged along the circumference of the annular groove 1112, that is, each third air hole 1121 is arranged sequentially along the circumference of the annular groove 1112.

[0071] After the exhaust unit 4 is activated, under the action of negative pressure, the airflow entering the annular groove 1112 can flow into the flow cavity 122 through each of the third air holes 1121, so that the airflow into the flow cavity 122 is smoother, and thus the air volume flowing in the flow cavity 122 is larger, and the heat dissipation effect is better.

[0072] In some combined embodiments, multiple second vents 1111 and third vents 1121 are provided, with each second vent 1111 being evenly arranged along the circumference of the annular groove 1112, and each third vent 1121 being evenly arranged along the circumference of the annular cavity. This further increases the airflow volume entering the flow channel and further improves the heat dissipation effect.

[0073] In optional embodiments, such as Figure 2 As shown, the earphone head also includes a tuning sticker 5, which is attached to the cover 112. After the outer shell 12 is connected to the cover 112, the outer shell 12 presses the tuning sticker 5 so that the tuning sticker is located between the outer shell 12 and the cover 112.

[0074] The setting of the tuning sticker 5 can adjust the vibration frequency of the cover 112 to adjust the timbre effect emitted by the sound unit 2.

[0075] As an optional embodiment, such as Figure 2 and Figure 7 As shown, the earphone head also includes a dustproof component 6. The dustproof component 6 is disposed within the vent 121 and is located on the outside of the exhaust unit 4, specifically on the side of the exhaust unit 4 closest to the outside. The dustproof component 6 separates the vent 121. Because the dustproof component 6 is located on the outside of the exhaust unit 4, when the exhaust unit 4 is not activated, the dustproof component 6 effectively prevents external dust from entering the flow cavity 122 through the vent 121. The dustproof component 6 should allow airflow to pass through so that when the exhaust unit 4 is activated, the airflow can be normally discharged through the vent 121.

[0076] Dustproof component 6 can be a filter screen or a cover with vents.

[0077] In some embodiments, such as Figure 2 and Figure 7 As shown, the dustproof component 6 includes a mesh frame 61 and a dustproof cloth 62. The dustproof cloth 62 is connected inside the mesh frame 61. The shape of the mesh frame 61 is consistent with the air outlet 121. The mesh frame 61 is placed inside the air outlet 121 and covers and blocks the outside of the exhaust unit 4. The dustproof cloth 62 is placed on the side of the mesh frame away from the exhaust unit 4. This prevents external dust from entering. The dustproof cloth 62 is breathable, allowing airflow to be discharged normally through the air outlet 121.

[0078] In an optional embodiment, the earmuff 3 includes an ear loop 31 and a filter element 32. The ear loop 31 is annular, and the filter element 32 is connected to the inner wall of the ear loop 31, such that one side of the filter element 32 forms a receiving groove 311 with the inner wall of the ear loop 31, and the other side of the filter element 32 forms a mounting groove 313 with the inner wall of the ear loop 31. When connecting the earmuff 3 to the housing 1, the mounting groove 313 is fitted onto the housing 1, making installation more convenient.

[0079] The filter element 32 can be filter cotton or dustproof cloth 62.

[0080] Regarding the setting of the first air hole 312, one end of the first air hole 312 penetrates the inner wall of the ear loop 31, and the other end penetrates the outer wall of the ear loop 31.

[0081] In some embodiments, the ear loop 31 includes a breathable foam sponge and an outer skin covering the periphery of the breathable foam sponge.

[0082] The outer skin has a first vent hole and a second vent hole on its inner and outer sides, respectively. The breathable foam sponge has a vent channel through it. The first vent hole, the vent channel and the second vent hole are aligned and connected in sequence to form the first air hole.

[0083] Even without ventilation channels, the breathable foam sponge can still allow airflow to pass through the second ventilation hole to the first ventilation hole by utilizing its breathability.

[0084] The outer skin is made of polyurethane.

[0085] According to embodiments of this application, another aspect also provides a headset, such as... Figure 8 As shown, it includes a headband 7 and earphone bodies 8, where the earphone body 8 can be any of the earphone heads mentioned above. Two earphone bodies 8 are provided, each connected to one end of the headband 7.

[0086] In use, the headband 7 is wrapped around the top of the user's head, so that the earcups 3 of one of the two earphone bodies 8 are placed on the user's left ear and the earcups 3 of the other earphone body 8 are placed on the user's right ear. Thus, the two earphone bodies 8 can emit sound from both sides of the head and be received by the user's left and right ears respectively.

[0087] The technical effects of this headset are the same as those of the headphone head, so they will not be described in detail here.

[0088] Although embodiments of this application have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of this application, and such modifications and variations all fall within the scope defined by this application.
