Description

Technical Field

[0001] The utility model relates to a wearable audio device, in particular to a bone conduction music lollipop. Background Art

[0002] Lollipops are candies that feature a bamboo or wooden stick inserted into the candy, making it easier for people to hold the candy and savor it. This unique design makes the candy easier to eat and also makes it more fun to eat. Lollipops can come in many shapes, including spheres, hearts, and animals, and the sticks are usually made of bamboo, wood, or plastic. Candies also come in a variety of flavors, including fruit, chocolate, mint, etc., to meet the taste needs of different people.

[0003] Lollipops have various variations and popularity all over the world, and they are not only a favorite snack for children, but also often used for festivals or as gifts. In addition, some specially designed lollipops, such as music lollipops, also combine modern technology, so that people can enjoy the fun of music while tasting delicious food.

[0004] With the existing bone conduction music lollipop, when the user turns on the switch and holds it in his hand, he can clearly hear the music playing, which causes the bone conduction music lollipop to leak sound. Many consumers mistake it for an ordinary audio speaker, which reduces the consumer experience. In addition, if the consumer temporarily takes the lollipop out of his mouth to talk or communicate, the music will continue to play without pausing or stopping. The continuity of the music or the integrity of the playback content is not good, and unnecessary power will be consumed, resulting in power waste. The existing inductive electrode sheet touch device uses the change of the capacitance signal to start, stop or end the audio playback, and the control sensitivity and effect are poor.

[0005] Therefore, in view of the technical problems described above, there is an urgent need for a bone conduction music lollipop with an enhanced structure. Utility Model Content

[0006] In view of this, the technical problem to be solved by the utility model is to overcome the defects of the above-mentioned technology and provide a music lollipop with better bone conduction sound effect and intelligent control. The purpose is to reasonably design the structural characteristics of the bone conduction related parts and a more sensitive intelligently controlled audio sensor unit.

[0007] In order to solve the above technical problems, the technical solution provided by the utility model is a bone conduction music lollipop with an enhanced structure, comprising an upper shell and a lower shell connected by a buckle, wherein the upper shell and the lower shell both comprise a candy portion, a support portion and a handle portion, a bone conduction speaker is arranged in the cavity between the candy portions of the upper and lower shells, a lithium battery, a circuit main board and a control switch are arranged in the cavity of the handle portion of the upper and lower shells, the bone conduction speaker is connected to the circuit main board and the control switch in the handle head through the wires in the cavity of the upper and lower shell support portions, and the characteristics are:

[0008] The candy part of the lower shell has a rough inner surface for absorbing the sound generated by the bone conduction speaker, thereby preventing the sound echo oscillation between the lower shell and the bone conduction speaker from being superimposed or resonating with the sound between the upper shell and the bone conduction speaker; a vibration enhancing structure for enhancing vibration is provided between the candy part of the upper shell and the bone conduction speaker, and the vibration enhancing structure can enhance the vibration between the bone conduction speaker and the upper shell for direct medium conduction, while blocking the path for sound propagation through the air.

[0009] As an improvement, the inner surface of the candy portion of the lower shell has a plurality of circular grooves that snap into place with a plurality of circular protrusions on the bottom of the base of the bone conduction speaker to fix the bone conduction speaker in the lower shell, thereby minimizing adhesion and improving the hygiene and food safety of the lollipop.

[0010] As an improvement, the inner side of the candy portion of the upper shell has a microporous structure for enhancing vibration conduction. The hole structure is similar to the microporous structure on a speaker. When the vibration is transmitted to the microporous structure, it can form an enhanced oscillation, thereby enhancing the vibration penetration through the candy portion of the upper shell and enhancing the vibration transmission effect.

[0011] As an improvement, the thickness of the candy portion of the upper shell is less than the thickness of the candy body of the lower shell, and the vibration is mainly transmitted through the part of the bone conduction speaker facing the candy portion of the upper shell. Reducing the thickness of the candy portion of the upper shell can further enhance the efficiency of vibration transmission. As an improvement, the thickness of the candy portion of the upper shell is 1 / 3 to 2 / 3 of the thickness of the candy body of the lower shell.

[0012] As an improvement, the interior of the candy portion of the upper shell has at least one circular reinforcing rib structure with the center as the dot. Alternatively, the interior of the candy portion of the upper shell has a cross-shaped reinforcing rib structure with the center as the dot. As the thickness of the candy portion of the upper shell is reduced, in order to enhance its support, and in combination with the directionality of the vibration and the amplitude of the vibration, a reinforcing rib structure can be provided inside the candy portion of the upper shell, and the protrusion of the reinforcing rib can further block the propagation efficiency of the sound.

[0013] As an improvement, the vibration enhancement structure is a sponge gasket or a metal elastic gasket or a spring structure, which is used to absorb sound waves and conduct the vibration of the bone conduction speaker. The sponge or metal elastic gasket can facilitate vibration transmission and absorb audio.

[0014] As an improvement, the vibration enhancement structure is a spring structure with central symmetry or axisymmetry, so that it can less affect the propagation of vibration.

[0015] As an improvement, the center of the shrapnel structure has a central disc structure that abuts against the bone conduction speaker, and the center of the disc structure has a circular through hole; the disc structure has at least two extended vibration spring arms, and the upper ends of the vibration spring arms are connected to the inner wall of the candy part of the upper shell. The metal shrapnel structure is a metal sheet, such as a copper sheet, an aluminum sheet, an iron sheet, etc.

[0016] As an improvement, the vibration spring arm is in a trumpet-shaped shape with a wider upper end and a narrower lower end; or the vibration spring arm is in a shape with a wider middle and narrower ends.

[0017] As an improvement, the upper end of the vibration spring arm has an opening structure that engages with the reinforcing rib structure, so as to fix the spring structure and conduct vibration.

[0018] As an improvement, the microporous structure takes the center point of the upper shell as the polar axis and satisfies the following distribution conditions:

[0019]

[0020] Among them, f(θ) is the probability density at angle θ, that is, the distribution of micropores at angle θ, θ is the angle range of 0°≤θ≤360° on the circumference with the center point of the shell as the polar axis, and the size of σ standard deviation determines the dispersion degree of distribution, which ranges from 15°≤σ≤90°. The above distribution is conducive to the propagation of vibration.

[0021] As an improvement, the microporous structure for enhancing vibration conduction is at least partially a through-hole structure.

[0022] As an improvement, the width of the reinforcing rib structure ranges from 0.1 cm to 0.5 cm.

[0023] As an improvement, the part of the candy head corresponding to the through-hole structure of the upper shell also has a micro body temperature or infrared sensor, which is electrically connected to the control switch. When in use, the control switch can be turned on first, and the control switch controls the body temperature or infrared sensor to work. When it detects that the lollipop is put into the mouth, it sends a command to play music to the circuit main board to play the music. In addition, when the lollipop is taken out of the mouth, the micro body temperature or infrared sensor sends an instruction to stop / terminate the playing of music to the outside. When the lollipop is in the cavity, the control switch can also be directly controlled to turn off / stop / pause the music playing.

[0024] The advantages of the utility model over the prior art are: the bone conduction music lollipop with an enhanced structure in the utility model uses a vibration enhancement structure that is conducive to vibration conduction, and optimizes the design of the upper shell and the lower shell, so that the effect of bone conduction is enhanced, and at the same time, the path of sound propagation through the air is suppressed, reducing the sound leakage phenomenon of the bone conduction lollipop. Furthermore, a micro body temperature or infrared sensor device is also added to the bone conduction music lollipop device of the utility model to achieve the continuity and integrity of the music playback content, saving resources.

[0025] Based on the above ideal embodiments of the present application, the relevant staff can make various changes and modifications without departing from the technical concept of the present utility model through the above description. The technical scope of the present utility model is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.

In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0038] In addition, the terms "horizontal", "vertical", "overhanging" and the like do not mean that the components must be absolutely horizontal or overhanging, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0039] In the description of the embodiments of the present invention, "multiple" means at least 2.

[0040] In the description of the embodiments of the present utility model, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0041] Combination Figure 1 A bone conduction music lollipop with an enhanced structure comprises an upper shell 1 and a lower shell 2 connected by snap fastening, wherein the upper shell 1 and the lower shell 2 respectively comprise 11, an upper shell candy portion, an upper shell support portion 12, and an upper shell handle portion 13; an upper shell switch button 14, a lower shell candy portion 21, a lower shell support portion 22, and a lower shell handle portion 23; a bone conduction speaker 31 is arranged in a cavity between the upper shell candy portion 11 and the lower shell candy portion 21; a lithium battery, a circuit main board 32, and a control switch 33 are arranged in a cavity between the upper shell handle portion 13 and the lower shell handle portion 23; the bone conduction speaker 31 is connected to the circuit main board 32 and the control switch 33 in the upper and lower shell handle portions through wires in the cavities of the upper and lower shell support portions 12 and 22;

[0042] The lower shell candy part 21 has a rough inner surface for absorbing the sound generated by the bone conduction speaker 31, and preventing the sound echo oscillation between the lower shell 2 and the bone conduction speaker 31 from being superimposed or resonated with the sound between the upper shell 1 and the bone conduction speaker 31; a vibration enhancement structure 4 for enhancing vibration is provided between the upper shell candy part 11 and the bone conduction speaker 31, and the vibration enhancement structure 4 can enhance the direct medium conduction of the vibration between the bone conduction speaker 31 and the upper shell 1, and at the same time can block the path of sound propagation through the air. Specifically, due to the provision of a medium for enhancing vibration propagation, when the bone conduction speaker 31 conducts vibration toward the front, that is, the direction of the upper shell candy body 11, the vibration wave can be directly transmitted to the inner wall of the upper shell candy part 11 through the vibration enhancement structure 4, and further directly transmitted to the candy body wrapped outside by the inner wall of the upper shell candy part 11. When the teeth bite the candy body or the supporting parts of the upper and lower shells, the vibration of the bone conduction speaker 31 is directly vibrated and propagated, thereby improving the path of direct medium propagation. At the same time, due to the existence of the vibration enhancement structure 4, the direct sound leakage generated by the bone conduction speaker 31 is blocked or cut by the medium, and the leakage sound is absorbed into the medium and converted into vibration conduction, thereby strengthening the vibration conduction and preventing people from hearing the leakage sound when they have not bitten the candy body.

[0043] It should be noted that the vibration enhancement structure 4 is preferably a metal spring.

[0044] In some optional embodiments, such as Figure 2-3 As shown, the inner surface of the candy portion 21 of the lower shell body has four circular grooves 211 for snapping, which snap into four circular protrusions 311 on the bottom of the base of the bone conduction speaker 31, so as to fix the bone conduction speaker 31 in the candy portion 21 of the lower shell body, thereby minimizing adhesion and improving the hygiene and food safety of the lollipop.

[0045] In some optional embodiments, such as Figure 4-5 As shown, the inner side of the candy portion 11 of the upper shell has a microporous structure 111 for enhancing vibration conduction; the microporous structure 111 for enhancing vibration conduction is at least partially a through-hole structure.

[0046] In some optional embodiments, the upper shell candy portion 11 has a cross-shaped reinforcing rib structure 112 with the center as the circle point, or the upper shell candy portion has at least one circular reinforcing rib structure 113 with the center as the circle point.

[0047] In some optional embodiments, the width of the reinforcing rib structure is 0.1 cm, 0.13 cm, 0.18 cm, 0.2 cm, 0.23 cm, 0.25 cm, 0.28 cm, 0.3 cm, 0.32 cm, 0.35 cm, 0.38 cm, 0.4 cm, 0.43 cm, 0.45 cm, 0.48 cm, or 0.5 cm.

[0048] In some optional embodiments, the microporous structure takes the center point of the upper shell as the polar axis and satisfies the following distribution conditions:

[0049]

[0050] Among them, f(θ) is the probability density at angle θ, that is, the distribution of micropores at angle θ, θ is the angle on the circumference with the center point of the shell as the polar axis, which can be selected as 0°, 20°, 30°, 45°, 50°, 60°, 90°, 100°, 120°, 130°, 150°, 1600°, 180°, 210°, 250°, 270°, 280°, 300°, 320°, 360°, and the size of the standard deviation of σ determines the degree of dispersion of the distribution, and the value can be 15°, 20°, 25°, 30°, 40°, 45°, 60°, 70°, 80°, 90°. The above formula can make the microporous structure appear as follows Figure 4As shown, they are distributed in the four quadrant regions of the disc, thus avoiding the part of the strengthening structure. Further, when the vibration enhancement structure is a structure that can be engaged with the cross-shaped reinforcing rib, a reasonable distribution can also be avoided.

[0051] In some alternative embodiments, such as Figure 6 As shown, the thickness h1 of the candy part 11 of the upper shell is less than the thickness h2 of the candy body 21 of the lower shell, that is, h1 < h2. Preferably, the thickness h1 of the candy part 11 of the upper shell is 1 / 3 to 2 / 3 of the thickness h2 of the candy body of the lower shell.

[0052] In some alternative embodiments, the vibration enhancement structure 4 is a sponge gasket or an elastic gasket or a spring structure, which is used to absorb sound waves and conduct the vibration of the bone conduction speaker.

[0053] In some alternative embodiments, such as Figure 7-8 As shown, from the side view and the top view, it can be seen that the vibration enhancement structure 4 is a metal shrapnel structure 4 with central symmetry or axial symmetry. The center of the shrapnel structure 4 has a central disc structure center 42 that abuts against the bone conduction speaker 31, and the disc structure center has a circular through hole; the disc structure 42 has four protruding vibration elastic arms, and the upper ends of the vibration elastic arms are connected to the inner wall of the candy part of the upper shell; the upper ends of the vibration elastic arms are wide and the lower ends are narrow, like a flared opening. In some alternative embodiments, the upper ends of the vibration elastic arms have an opening structure 41 that can be engaged with the reinforcing rib structure 112.

[0054] In some alternative embodiments, the inner wall of the candy part 11 of the upper shell of the aforementioned bone conduction music lollipop with a strengthening structure further has a micro body temperature or infrared sensor 5, which is connected to the control switch 33 and the circuit main board 32; the micro body temperature or infrared sensor is close to the through hole structure part, which is convenient for accurate body temperature or infrared sensing. Such as Fig. 9As shown, the circuit main board 32 includes a sensing circuit 321 and a playing circuit 322 which are electrically connected in sequence. One end of the sensing circuit is connected to the body temperature or infrared sensor 5, and the other end is electrically connected to the control switch 33. The output end of the playing circuit 322 is electrically connected to the bone conduction speaker 31; the battery is connected to the circuit main board 32 to form a power supply circuit. When in use, the user will first turn on the control switch 33, and the control switch 33 will first control the sensing circuit 321 to work, so that the body temperature or infrared sensor 5 performs detection. When it detects that the lollipop is put into the mouth, that is, the temperature rises or the infrared signal is sensed. The body temperature or infrared sensor 5 sends a sensing signal to the sensing circuit 321, and the sensing circuit 321 sends a music playing instruction to the playing circuit 322 and the control switch 33 at the same time. When the playing circuit receives feedback from the two signals, it plays the music, and the music signal is transmitted to the bone conduction speaker 31 through the playing circuit. When the lollipop is taken out of the mouth, the micro temperature or infrared sensor 5 sends a command to stop / terminate the playing of music to the playing circuit and the control switch 33 at the same time. After receiving the command to stop / terminate the playing of music from the sensing circuit 321, the control switch 33 also sends a command to stop / terminate the playing of music to the playing circuit 322. After the playing circuit 322 receives the two commands to stop / terminate the playing of music, it stops / terminates the playing of music. In addition, when the lollipop is in the mouth, when the control switch is pressed, the control switch 33 can also send a command to stop / terminate the playing of music to the sensing circuit 321 and the playing circuit 322. After receiving the termination command, the sensing circuit 321 also sends a command to stop / terminate the playing of music to the playing circuit 322. After the playing circuit 322 receives the two commands to stop / terminate the playing of music, it stops / terminates the playing of music.
