Description

Technical Field

[0001] The utility model belongs to the field of eye masks, and particularly designs a sound generating unit, a sound generating component and an eye mask. Background Art

[0002] Eye masks are a kind of sleeping product used to cover the eyes to block light and create a dark environment. In today's society, people's pace of life is accelerated, sleep time is short, and sleep quality is poor. Therefore, eye masks, which can create a comfortable sleeping environment, are gradually becoming popular. Moreover, in order to meet people's needs, eye masks with different functions have gradually appeared. For example, eye masks that can heat the eyes to relieve eye fatigue, eye masks that can massage the eyes, eye masks that can play music, and eye masks that can monitor sleep quality.

[0003] At present, eye masks that can play music usually use wired or wireless methods to connect to the sound source, and produce sound through speakers built into the eye masks. In today's music eye masks, speakers are usually divided into two types, namely in-ear and external. Among them, in-ear speakers can be inserted into the ear and have good sound quality; but since such speakers need to be inserted into the ear, they may cause pressure on the ear during sleep, and the comfort level is not high. The external speaker is located next to the ear, which has less pressure on the ear, but the sound quality is not good. Therefore, it is difficult for existing music eye masks to take into account both comfort and sound quality. Utility Model Content

[0046] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0047] In order to ensure wearing comfort, today's music eye masks usually use external speakers. When wearing this kind of eye mask, the speaker is located outside the ear, and the sound quality is poor. Although using a better quality speaker can improve the sound quality to a certain extent, the cost is high.

[0048] The inventors found that the speaker of the above-mentioned eye mask is usually fixed at a position of the eye mask; after the eye mask is worn, the speaker is located in the vicinity of the ear. However, since the existing speakers used in eye masks are usually wide-area propagation, that is, the speaker emits sound in one direction and the sound propagation angle is wide. Therefore, the sound of this speaker is not concentrated, resulting in poor sound quality. Moreover, since the size of each person's head circumference is inconsistent, the position of the speaker in the eye mask cannot be well adapted to the position of the wearer's ear, so that the main sound propagation direction of the speaker does not correspond well to the position of the ear, that is, the sound of the speaker cannot be well propagated to the wearer's ear, thereby affecting the wearer's hearing.

[0049] Embodiment 1

[0050] In order to solve the above problems, the first aspect of the present embodiment discloses a sound generating unit 1, which is applied to an eye mask, such as Figure 1 As shown, it includes a housing 11 and a speaker 12:

[0051] The housing 11 includes:

[0052] The accommodating cavity 111 is used to place the speaker 12;

[0053] A sound guiding cavity 112 is communicated with the accommodating cavity 111, and the sound emitting direction of the speaker 12 is toward the sound guiding cavity 112;

[0054] The sound outlet 113 is communicated with the sound guiding cavity 112 .

[0055] In the sound-emitting unit 1, the sound-guiding cavity 112 connected to the accommodating cavity 111 can be used to propagate the sound emitted by the loudspeaker 12; and the sound emitted by the loudspeaker 12 can be reflected in the sound-guiding cavity 112, so that the sound reverberates, thereby making the sound thicker and improving the sound quality. The sound outlet 113 connected to the sound-guiding cavity 112 can make the sound reflected in the sound-guiding cavity 112 be concentrated and exported through the sound outlet 113, so that the sound can be more concentrated and have stronger directivity, thereby making the sound-emitting unit 1 have better sound effects within its sound propagation angle range.

[0056] In some eye masks using the sound unit 1, the sound emitted by the sound unit 1 in this embodiment has strong directivity. Therefore, in practical applications, it is only necessary to roughly point the sound propagation direction of the sound unit 1 toward the wearer's ear to obtain better sound quality. Moreover, since the sound unit 1 has strong directivity, the sound unit 1 has an optimal propagation angle range. Therefore, in practical applications, it is only necessary to control the position of the sound unit 1 in the eye mask according to the adjustable size of the eye mask and the position of the ear corresponding to the size, so that the eye mask is within the adjustable size range, and the wearer's ear can always be located within the optimal sound propagation angle range of the sound unit 1, so as to obtain a better sound quality experience.

[0057] Moreover, in this embodiment, in order to ensure the sound quality of the speaker 12, a vent hole 118 is further provided in the accommodating cavity 11, and the vent hole 118 is used to connect the accommodating cavity 11 and the external space of the sound-emitting unit.

[0058] The second aspect of the present embodiment further discloses a sound-generating component 2, which is applied to an eye mask, such as Figure 2 As shown, including:

[0059] The sound generating unit 1 described above;

[0060] A resonance chamber 21, wherein the length direction of the resonance chamber 21 extends along the sound propagation direction of the sound generating unit 1;

[0061] The sound outlet holes 22 are connected to the resonance cavity 21 , and a plurality of the sound outlet holes 22 are evenly distributed along the length extension direction of the resonance cavity 21 .

[0062] In the sound-emitting component 2, the resonance cavity 21 is connected to the sound outlet 113 of the sound-emitting unit 1, and the length direction of the resonance cavity 21 is extended along the sound propagation direction of the sound-emitting unit 1, so that the sound propagated by the sound-emitting unit 1 through the sound outlet 113 can enter the resonance cavity 21, so that the sound can be emitted in the resonance cavity 21 and reverberate in the resonance cavity 21, further making the sound thicker, thereby improving the sound quality. The sound outlet 22 is connected to the resonance cavity 21, so that the sound in the resonance cavity 21 can be concentrated and exported through the sound outlet 22. In addition, the sound outlet 113 is evenly distributed along the length extension direction of the resonance cavity 21, so that the sound can be propagated outward through multiple sound outlets 22; and each sound outlet 22 corresponds to a sound propagation angle, and multiple sound outlets 22 evenly distributed along the length extension direction of the resonance cavity 21 can make the sound cover a wider area to adapt to the head circumference of different wearers.

[0063] The third aspect of this embodiment also discloses an eye mask, such as Figure 3 As shown, including:

[0064] Cover body 31;

[0065] The connecting parts 32 are connected to two sides of the cover body 31 and are connected to each other to form a loop so as to be put on the head of a person;

[0066] The sound-generating component 2 described above is arranged on the connecting portion 32 .

[0067] Among them, the cover body 31 covers the eye area when in use to block light. The connecting part 32 has two parts, which are respectively connected to the two sides of the cover body 31, and are connected to each other to fix the cover body 31 to the eye area, so as to achieve wearing. It should be noted that when worn, the cover body 31 is located at the eye area, and the connecting part 32 extends from the two sides of the cover body 31 toward the back of the head, and finally connected together at the back of the head. Such connection makes the cover body 31 and the connecting part 32 form an annular structure, which is very convenient to wear. In some embodiments, the connecting parts 32 can be connected together by Velcro, straps, buckles, etc. In addition, the connecting part 32 can also be set to a structure with adjustable length to adapt to wearers with different head circumferences.

[0068] In this embodiment, the resonance cavity 21 is arranged along the length extension direction of the connecting portion 32. It should be noted that, according to the adjustable size range of the eye mask, the position range of the wearer's ear relative to the eye mask can be obtained. The length of the resonance cavity 21 can be set to correspond to the position range, so that when wearers with different head circumferences wear the eye mask, the wearer's ear can always be located in the area corresponding to the resonance cavity 21, so that a part of the sound outlet hole 22 on the resonance cavity 21 can always correspond to the position of the ear, that is, the wearer's ear can always be located within the sound propagation angle range of the sound-emitting component 2, so as to ensure better sound quality.

[0069] It should be noted that the outer side and inner side of the connecting portion 32 mentioned herein refer to the orientation of the connecting portion 32 when the eye mask is worn. Figure 3 As shown, the mask body 31 in the eye mask and the connecting parts 32 respectively connected to the two sides of the mask body 31 cooperate to form an annular structure for wearing on the head of the user. At this time, relative to any one of the connecting parts 32, the part located in the annular structure is called the inner side of the connecting part 32, and the part outside the annular structure is called the outer side of the connecting part 32.

[0070] Embodiment 2

[0071] This embodiment discloses a sound unit 1, a sound component 2 and an eye mask. This embodiment is a further improvement based on the first embodiment, and the improvement is that the angle between the sound emission direction of the speaker 12 and the sound propagation direction of the sound outlet 113 is greater than 60° but less than 120°.

[0072] Through such an arrangement, on the one hand, the sound emitted by the speaker 12 needs to be reflected in the sound guiding cavity 112 and then output from the sound outlet 113. After the sound is reflected in the sound guiding cavity 112, the sound can reverberate, thereby making the sound thicker; on the other hand, the thickness of the shell 11 can be reduced to make the shell 11 flatter, thereby adapting to the flat shape of the connecting portion 32 of the eye mask and improving the wearing comfort of the eye mask.

[0073] It can be seen from the first embodiment that the sound unit 1 can be directly applied to the eye mask, that is, the sound unit 1 is built into the connecting portion 32 of the eye mask. When the eye mask is worn on the wearer's head, the sound propagation direction of the sound unit 1, that is, the sound propagation direction of the sound outlet 113, is roughly directed to the wearer's ear.

[0074] From the top perspective of the wearer, the head of the wearer is roughly oval. Therefore, when the eye mask is worn, the sound propagation direction of the sound-emitting unit 1 inside the eye mask is not directly pointed to the direction of the wearer's ears, but may be offset to a certain extent. Therefore, after the above design, the sound propagation direction of the sound outlet 113 can be offset toward the inner side of the connecting portion 32 to point to the position of the wearer's ears.

[0075] Therefore, in some more preferred embodiments, the angle between the sound emission direction of the speaker 12 and the sound propagation direction of the sound outlet 113 is greater than 60° and less than 80°, or the angle between the sound emission direction of the speaker 12 and the sound propagation direction of the sound outlet 113 is greater than 100° and less than 120°. After the above design, the sound propagation direction of the sound outlet 113 can be offset toward the inner side of the connecting portion 32 to point to the position of the wearer's ear, thereby obtaining a better sound experience.

[0076] In order to further improve the sound reflection effect of the sound guide cavity 112, as Figure 1 and Figure 4 As shown, in some preferred embodiments, a reflective wall 114 is provided in the sound guiding cavity 112 , and the reflective wall 114 intersects with the sound propagation direction of the speaker 12 to reflect the sound to the direction of the sound outlet 113 .

[0077] Specifically, in some embodiments, Figure 1 As shown, the reflective wall 114 is one of the inner walls of the sound guiding cavity 112 .

[0078] Furthermore, in order to improve the sound reflection effect and enable the reflection wall 114 to reflect most of the sound and make it pass out from the sound outlet 113 at a specific angle, the angle between the reflection wall 114 and the sound propagation direction of the speaker 12 is between 30° and 60°.

[0079] In other embodiments, Figure 4 As shown, the reflective wall 114 is independently provided from the inner wall of the sound guiding cavity 112. In some preferred embodiments, in order to improve the reverberation effect of the sound in the sound guiding cavity 112, a sound leakage hole 115 is provided on the surface of the reflective wall 114, and the sound leakage hole 115 is used to allow part of the sound waves to pass through.

[0080] In some embodiments, Figure 1 and Figure 5 As shown, the housing 11 further includes:

[0081] A sound absorbing cavity 116, which is communicated with the accommodating cavity 111 and isolated from the external space, and the sound absorbing cavity 116 is filled with sound absorbing material;

[0082] The sound outlet 113 is provided with a partition 117 , and an extending direction of the partition 117 is parallel to a sound propagation direction of the sound outlet 113 .

[0083] Among them, Figure 1 As shown, the sound absorbing cavity 116 is connected with the accommodating cavity 111, and the speaker 12 is located in the accommodating cavity 111, and the sound guiding cavity 112 is isolated from the sound absorbing cavity 116, wherein the sound guiding cavity 112 is located in the sound emitting direction of the speaker 12, and the sound absorbing cavity 116 is located in the opposite direction of the sound emitting direction of the speaker 12; that is, the sound absorbing cavity 116 forms the inner cavity of the sound generating unit. The sound absorbing cavity 116 is filled with an absorbing material, and the filled sound absorbing material can absorb the sound waves in the opposite direction of the speaker, prevent the sound waves from being reflected and refracted, and disturb the normal sound waves; so as to eliminate the vibration of the shell 11 as much as possible, thereby obtaining the best bass performance. It can be understood that in this embodiment, the sound absorbing cavity 116 can be a part of the accommodating cavity 111, that is, the remaining space in the accommodating cavity 111 after the speaker 12 is placed is the sound absorbing cavity 116.

[0084] In addition, if Figure 5 As shown, the partition 117 arranged at the sound outlet 113 serves to perform directional processing on the sound waves emitted by the loudspeaker 12 so as to further improve the directivity of the sound of the sound producing unit.

[0085] Embodiment 3

[0086] This embodiment discloses a sound unit 1, a sound component 2 and an eye mask. This embodiment is a further improvement made based on the first or second embodiment. Figure 2 As shown, the improvements are:

[0087] The sound outlet 22 is located at one side of the resonance cavity 21 along the length extension direction of the resonance cavity 21;

[0088] An inner wall of the resonance cavity 21 opposite to the sound outlet hole 22 intersects with the sound propagation direction of the sound emitting unit 1 so as to reflect the sound in the direction of the sound outlet hole 22 .

[0089] Specifically, in the present embodiment, the sound outlet hole 22 is located on the side of the resonance cavity 21 close to the inner side of the connection portion 32 to propagate the sound to the ear. In the present embodiment, after the directional sound emitted by the sound-emitting unit 1 enters the resonance cavity 21, it will be reflected in the resonance cavity 21 and propagated through the sound outlet hole 22. The inner wall of the resonance cavity 21 opposite to the sound outlet hole 22 intersects with the sound propagation direction of the sound-emitting unit 1. This setting can control the emission direction of the sound in the resonance cavity 21 so that the sound can accurately reflect the direction of the sound outlet hole 22. In essence, the role of the inner wall of the resonance cavity 21 opposite to the sound outlet hole 22 is similar to that of the above-mentioned reflection wall 114, and its purpose is to control the propagation direction of the sound through the above-mentioned setting.

[0090] In addition, in order to further improve the sound reflection effect, in some preferred embodiments, the resonance chamber 21 has a smooth inner wall.

[0091] In addition, in some embodiments, Figure 2 As shown, the sound-generating component 2 also includes:

[0092] A housing 23, wherein the housing 23 forms the resonance cavity 21;

[0093] The sound unit 1 is detachably installed in the housing 23 .

[0094] In this embodiment, a resonance cavity 21 is formed in the housing 23, and the sound unit 1 is detachably mounted in the housing 23. By such a configuration, the sound unit 1 is detachably mounted on the housing 23, so that the sound unit 1 can be adjusted to have a housing 23 with resonance cavities 21 of different specifications as needed, that is, one sound unit 1 can be adapted to housings 23 of various specifications, which is conducive to reducing costs; and when the sound unit 1 fails, it can be repaired by replacing the sound unit 1, and the repair cost is low.

[0095] In addition, the sound unit 1 is designed to be detachable, and the housing 23 and the sound unit 1 are separated into two relatively independent components. During production, the difficulty of production can be relatively reduced, thereby improving efficiency and reducing production costs.

[0096] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the embodiments of the utility model rather than to limit them. Although the embodiments of the utility model are described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the embodiments of the utility model can still be modified or replaced by equivalents, and these modifications or equivalent replacements cannot cause the modified technical solutions to deviate from the scope of the technical solutions of the embodiments of the utility model.
