Description

Technical Field

[0001] The present invention belongs to the technical field of earphones, and particularly relates to an earphone head and a head-mounted earphone. Background Art

[0002] During the use of traditional earphone heads, they usually cause a certain degree of sound insulation to the ears' acquisition of surrounding environmental sounds, posing potential risks in situations such as driving and outdoor running. Specifically, for example, in-ear earphone heads need to be partially or entirely inserted into the ears and block the ears, which will cause a certain degree of blockage to the ears' acquisition of surrounding environmental sounds. And for example, over-ear earphone heads need to entirely cover the ears, which will also cause a certain degree of blockage to the ears' acquisition of surrounding environmental sounds. Summary of the Invention

[0003] An object of the present invention is to overcome the above-mentioned deficiencies of the prior art and provide an earphone head, which aims to solve the problem that the earphone head causes a certain degree of blockage to the ears' acquisition of surrounding environmental sounds during use.

[0004] The present invention is implemented as follows:

[0005] An earphone head, comprising:

[0006] A sound wave generating device for generating sound waves;

[0007] An earphone structure housing, worn on the cheek and located on the periphery of the ear. The earphone structure housing is provided with a receiving cavity and a sound outlet hole. The receiving cavity houses the sound wave generating device, and the sound outlet hole communicates the receiving cavity to the outside and is opened in a direction pointing to the ear.

[0008] Optionally, the earphone structure housing can constrain the sound energy transmission direction of the sound waves generated by the sound wave generating device and transmitted through the sound outlet hole to the opening direction of the sound outlet hole.

[0009] Optionally, the sound wave generating device divides the receiving cavity into a full-frequency cavity and a low-frequency cavity. The full-frequency cavity communicates with the sound outlet hole, and the sound outlet surface of the sound wave generating device faces the full-frequency cavity;

[0010] The earphone structure housing is further provided with a bass hole, which is arranged at an interval from the sound outlet hole and communicates the receiving cavity to the outside and is opened in a direction pointing to the ear.

[0011] Optionally, a sound guiding tube structure is formed in the receiving cavity of the earphone structure housing. The sound guiding tube structure is provided with a sound guiding channel. One channel opening of the sound guiding channel communicates with the low-frequency cavity, and the other channel opening communicates with the bass hole.

[0012] Optionally, the sound wave generating device has a flat structure, and one flat side is the sound outlet surface;

[0013] The sound-emitting surface of the acoustic wave generating device faces the cheek.

[0014] Optionally, the sound-emitting hole is a strip-shaped hole, and the length direction is parallel to the sound-emitting surface of the acoustic wave generating device.

[0015] Optionally, the housing of the headphone structure is made of a hard material, and a sticker film made of a soft material is connected to the side surface facing the cheek.

[0016] Optionally, the middle area of the sticker film is spaced from the housing of the headphone structure, while the edge area is connected to the housing of the headphone structure.

[0017] Optionally, a first sound pickup hole communicating with the accommodation cavity is formed on the side surface of the housing of the headphone structure facing away from the cheek. The headphone head further includes a first acoustic wave pickup device, which is located in the accommodation cavity, is disposed opposite to the first sound pickup hole, and is used to pick up the acoustic waves outside the housing of the headphone structure from the first sound pickup hole;

[0019] The present invention further provides a head-mounted headphone, which is characterized in that it includes the headphone head as described above.

[0020] During the specific use process, the headphone head is worn on the cheek and is located on the periphery of the ear. First, the headphone head will not block the ear during use, avoiding blocking the ear from obtaining the surrounding environmental sounds. Second, since the housing of the headphone structure is provided with a sound-emitting hole, the acoustic waves generated by the acoustic wave generating device can be transmitted out from the sound-emitting hole, enabling the ear adjacent to the sound-emitting hole to receive the acoustic waves generated by the acoustic wave generating device, thereby realizing the basic function of the headphone head to play audio.

[0021] As can be seen from the above, based on the structural design of this invention, the headphone head will not block the ear during use, avoiding blocking the ear from obtaining the surrounding environmental sounds.

[0031] Detailed implementation manners

[0032] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the following further details the present invention in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0033] An embodiment of the present invention provides a headphone head.

[0034] Please refer to Figures 1 to 5 , the headphone head includes a sound wave generating device 100 and a headphone structure housing 200.

[0035] The sound wave generating device 100 is used to generate sound waves, and the sound waves are transmitted through the air. Specifically, a speaker is usually adopted, and the air is vibrated by vibrating the diaphragm.

[0036] The earphone structure housing 200 is worn on the cheek and is located around the ear. Specifically, it is usually in front of the ear. Of course, it can also be in the front lower part of the ear. In this way, the ear will not be blocked during use, avoiding blocking the ear from obtaining surrounding environmental sounds. The earphone structure housing 200 is provided with a receiving cavity 201 and a sound outlet hole 202. The receiving cavity 201 houses the sound wave generating device 100, and the sound outlet hole 202 connects the receiving cavity 201 to the outside and is opened in a direction pointing to the ear. Among them, due to the certain blockage of the sound wave transmission by the physical structure of the earphone structure housing 200 itself, based on the structure of the earphone structure housing 200, the sound waves generated by the sound wave generating device 100 can be transmitted out through the sound outlet hole 202.

[0037] During the specific use process, the earphone head is worn on the cheek and is located around the ear. First of all, the earphone head will not block the ear during use, avoiding blocking the ear from obtaining surrounding environmental sounds. Secondly, since the earphone structure housing 200 is provided with a sound outlet hole 202, the sound waves generated by the sound wave generating device 100 can be transmitted out through the sound outlet hole 202, enabling the ear near the sound outlet hole 202 to receive the sound waves generated by the sound wave generating device 100, thus realizing the basic function of the earphone head to play audio.

[0038] As can be seen from the above, based on the structural design of this invention, the earphone head will not block the ear during use, avoiding blocking the ear from obtaining surrounding environmental sounds. In this way, in some special use scenarios, such as driving, running outdoors, etc., potential dangers can be effectively reduced.

[0039] It should be noted here that the earphone head shown in the attached drawing is suitable for the left ear. When this earphone head needs to be suitable for the right ear, only adaptive adjustment is required.

[0040] It should be noted here that in the present invention, the earphone structure housing 200 is composed of a first outer shell 210 and a second outer shell 220 that are buckled and matched with each other.

[0041] In the embodiment of the present invention, the earphone structure housing 200 can constrain the sound energy transmission direction of the sound waves generated by the sound wave generating device 100 and transmitted through the sound outlet hole 202 to the opening direction of the sound outlet hole 202. Based on this structural design, during the specific use process, it can prevent others around the user from hearing the sound waves generated by the sound wave generating device 100.

[0042] It should be noted here that to realize that the earphone structure housing 200 constrains the sound energy transmission direction of the sound waves to the opening direction of the sound outlet hole 202, it is also necessary to cooperate with the control of the generation frequency of the sound wave generating device 100. Specifically, to realize sound wave constraint, it is necessary to perform frequency modulation on the sound wave generating device 100 and design the earphone structure housing 200. In the specific implementation process, those skilled in the art can achieve it through multiple experimental simulations.

[0043] See also Figure 3 In the embodiment of the present invention, the sound wave generating device 100 divides the accommodating cavity into a full-frequency cavity 2011 and a low-frequency cavity 2012. The full-frequency cavity 2011 is connected to the sound outlet 202, and the sound outlet surface of the sound wave generating device 100 faces the full-frequency cavity 2011; the earphone structure shell 200 also has a bass hole 203, which is spaced apart from the sound outlet 202, and the accommodating cavity 201 is connected to the outside and is opened in a direction pointing to the ear. The sound wave generating device 100 will generate some low-frequency sound waves on the side opposite to the sound outlet surface. The low-frequency sound waves generated by the sound wave generating device 100 will be transmitted from the bass hole 203, and will also directly reach the ear through the bass hole 203. In this way, the user can obtain more low-frequency sound waves, thereby improving the sound effect.

[0044] Furthermore, in the embodiment of the present invention, the earphone structure housing 200 is provided with a sound guide tube structure 230 in the accommodating cavity 201. The sound guide tube structure 230 is provided with a sound guide channel, one channel opening of the sound guide channel is connected to the low frequency cavity 2012, and the other channel opening is connected to the bass hole 203. The sound guide tube structure 230 is conducive to improving the low frequency lower limit of the earphone head, which is conducive to further improving the sound effect.

[0045] See also Figure 5 In the embodiment of the present invention, the sound wave generating device 100 is a flat structure, and a flat side surface is a sound outlet surface; the sound outlet surface of the sound wave generating device 100 faces the cheek. Based on this structural design, it is helpful to reduce the thickness of the earphone head in the direction away from the cheek.

[0046] Furthermore, the sound outlet hole 202 is a strip-shaped hole, and the length direction is parallel to the sound outlet surface of the sound wave generating device 100. In this way, under the condition of the same sound output volume, it is helpful to further reduce the thickness of the earphone head.

[0047] Specifically, in a specific implementation, the length of the sound outlet surface in the length direction of the sound outlet hole 202 is equal to the length of the sound outlet hole 202 , and the sound outlet surface is arranged opposite to the sound outlet hole 202 .

[0048] See also Figure 3, in the embodiment of the present invention, the headphone structure housing 200 is made of a hard material. For example, if the headphone structure housing 200 is made of a soft material, then when the headphone structure housing 200 is subjected to an external force, it will undergo elastic deformation and cause extrusion to the sound wave generating device 100 inside the headphone structure housing 200. However, being made of a hard material, it can not deform when subjected to an external force, such as polypropylene, etc.; The headphone structure housing 200 is connected to the side facing the cheek with a face mask 240 made of a soft material. In this way, when the headphone is worn on the cheek, the face mask 240 will directly contact the cheek. Among them, since the face mask 240 is made of a soft material, this can improve the comfort when wearing the headphone.

[0049] Furthermore, the middle area of the face mask 240 is spaced from the headphone structure housing 200, while the edge area is connected to the headphone structure housing 200. Among them, since the middle area of the face mask 240 is spaced from the headphone structure housing 200, this space provides deformation space for the face mask 240. In this way, when wearing the headphone, it can better adapt to the user's cheek, thereby improving the comfort of use.

[0050] Please refer to Figures 1 to 5 , in the embodiment of the present invention, a distance sensor 300 is provided on the side of the headphone facing the cheek. The distance sensor 300 is used to detect whether the headphone is worn on the cheek and activate the headphone when it detects that the headphone is worn on the cheek. Through the detection of the distance sensor 300, the headphone is activated when it detects that the headphone is worn on the cheek, and the headphone is turned off when it detects that the headphone is not worn on the cheek. In this way, it can save the power consumption of the headphone. When this headphone is applied to a wireless headphone, it can greatly increase the battery life of the wireless headphone.

[0051] Please refer to Figures 1 to 5 , in the embodiment of the present invention, a first sound pickup hole 204 communicating with the accommodation cavity 201 is opened on the side of the headphone structure housing 200 facing away from the cheek. The headphone further includes a first sound wave pickup device 400. The first sound wave pickup device 400 is located in the accommodation cavity 201, blocks the first sound pickup hole 204, and is used to pick up the sound wave outside the headphone structure housing 200 from the first sound pickup hole 204. A second sound pickup hole 205 communicating with the accommodation cavity 201 is opened on the side of the headphone structure housing 200 facing away from the sound outlet hole 202. The headphone further includes a second sound wave pickup device 500. The second sound wave pickup device 500 is located in the accommodation cavity 201, blocks the second sound pickup hole 205, and is used to pick up the sound wave outside the headphone structure housing 200 from the second sound pickup hole 205.

[0052] In the actual use process, due to the different positions of the first sound wave pickup device 400 and the second sound wave pickup device 500, the picked-up sound waves are also different. Specifically, according to the situations of the first sound wave pickup device 400 and the second sound wave pickup device 500 picking up sound waves, it is convenient for the earphone head to distinguish which is the environment and which is not, so that the earphone head can be used for calls.

[0053] Please refer to Figure 3 , in the embodiment of the present invention, dust-proof nets 600 are provided at the sound outlet holes 202 and the bass holes 203. Through the dust-proof nets 600, it is possible to prevent external objects from entering the accommodation cavity 201 through the sound outlet holes 202 and the bass holes 203.

[0054] Please refer to Figure 6 , the present invention also proposes a head-mounted earphone. The head-mounted earphone includes an earphone head. The specific structure of the earphone head refers to the above-mentioned embodiment. Since the head-mounted earphone adopts all the technical solutions of the above-mentioned all embodiments, it also has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be elaborated here one by one.

[0055] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements or improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
