Description

Technical Field

[0001] This invention relates to the field of mobile phone case technology, and in particular to a bone conduction mobile phone case and its manufacturing mold and manufacturing method. Background Technology

[0002] With the trend of mobile phones becoming thinner and lighter, mobile phone cases (protective cases), as a sub-segment of the mobile phone industry, have seen a continuous increase in market demand due to their low manufacturing threshold and high plasticity.

[0003] Currently, most phone cases on the market primarily serve to protect the user, increase grip friction, and enhance aesthetics. However, functional phone cases are scarce. One type, bone conduction phone cases, utilizes the principle of sound transmission through bone conduction, eliminating the need for direct transmission through the eardrum. This innovative concept of bone conduction transmits sound directly to the nerves inside the ear via the skull, minimizing the impact on hearing and providing significant assistance to people with hearing impairments. This type of functional phone case is poised to occupy a significant position in the functional phone case market.

[0004] Currently, 360 million people worldwide suffer from deafness or hearing impairment, accounting for 5% of the global population. The development of bone conduction phone cases could meet the mobile phone needs of people with hearing impairments. However, there are currently few mature applications of bone conduction phone cases on the market, and even fewer suppliers can provide supporting mass production solutions. Moreover, most bone conduction phone cases on the market do not meet the required quality standards.

[0005] To address the functional requirements of bone conduction in phone cases, research and development must not only meet the softening and aesthetic standards of phone cases but also provide a structural solution that supports bone conduction functionality. Achieving these technical requirements fully is a critical technical challenge that needs to be addressed in existing bone conduction phone case manufacturing processes.

[0006] In the existing bone conduction phone case manufacturing process, the problem of trapped air in the molding mold is difficult to solve well, resulting in an uneven bone conduction surface of the phone case, which makes it difficult to achieve a good conduction effect and a poor user experience.

[0007] Therefore, there is an urgent need to propose a new technical solution to address the above problems. Summary of the Invention

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0054] The essence of the present invention will be further explained below with reference to the accompanying drawings and embodiments.

[0055] Example 1

[0056] Existing bone conduction phone cases suffer from air trapping issues during the molding process, resulting in uneven conductive surfaces on the surface where the bone conduction transducer contacts the transducer. This leads to poor sound conduction and a poor user experience. Furthermore, bone conduction phones are injection molded from TPU (polyurethane elastomer rubber) granules, which have poor material flowability. The main functional and aesthetic surfaces are located at the product's end, and the structural characteristics require the glue to flow around mold inserts to form a back-bonding process, resulting in encapsulation, air trapping, and glue shortages, affecting both appearance and function. To address these problems, this invention provides a bone conduction phone case with superior conductivity. This case features a smooth conductive surface where the transducer contacts the transducer, allowing for better sound conduction, improving the user experience, and resolving the issue of poor air venting at the contact surface of the transducer in existing bone conduction phone cases.

[0057] Combination Figure 1 The bone conduction phone case provided by this invention includes a phone case body, which comprises a first housing 110 and a second housing 120. The first housing 110 is configured to accommodate the phone body, and the second housing 120 is configured to form an electronic component chamber for processing and playing audio from the phone. Therefore, the bone conduction phone case provided by this invention combines the functions of accommodating a phone and bone conduction.

[0058] In one embodiment, the first housing 110 has a first opening 111 and a first storage cavity 112 communicating with the first opening 111. The mobile phone body is placed in the first storage cavity 112 through the first opening 111, that is, the first storage cavity ensures the function of a traditional mobile phone case.

[0059] In one embodiment, see Figure 2The second housing 120 is disposed on one side of the first housing 110. The second housing 120 has a second opening 121 and a first receiving cavity 123 communicating with the second opening 121. The first receiving cavity 123 forms the electronic component chamber. The opening orientation of the second opening 121 is opposite to the opening orientation of the first opening 111. A bone conduction oscillator is disposed in the first receiving cavity 123, therefore, the bottom of the first receiving cavity forms a bone conduction surface.

[0060] In one embodiment, the bottom plane of the second housing 120 is flush with the first opening 111, and the bottom plane of the second housing 120 is configured to form a bone conduction surface 122 that contacts the human skull. This further illustrates that the flat bone conduction surface structure of the mobile phone case of the present invention facilitates sound conduction. The media sound from the mobile phone is processed by the electronic components in the electronic component chamber and then conducted to the human skull via the bottom plane of the second housing 120, completing the bone conduction process.

[0061] In one embodiment, the first housing 110 further includes a second storage cavity 113, which communicates with the first storage cavity 112. The second storage cavity 113 is a recess formed by downward indentation from the bottom of the first storage cavity 112. The second storage cavity 113 is configured to accommodate an integrated circuit board. When the mobile phone body is accommodated in the first storage cavity 112, the integrated circuit board is embedded in the second storage cavity 113 and is disposed opposite to the mobile phone body. That is, the mobile phone case of the present invention is thicker than a regular mobile phone case because an integrated circuit board needs to be placed under the cavity accommodating the mobile phone to realize the transmission of sound from the mobile phone media.

[0062] In one embodiment, see Figure 2 The second storage cavity 113 has a first through hole 114 and a second through hole 115 on its side wall. The second storage cavity 113 is connected to the first receiving cavity 123 through the first through hole 114, and the first through hole 114 allows wires to pass through.

[0063] In one embodiment, an energy storage device is provided on the integrated circuit board, and the second through-hole 115 is disposed opposite to the charging port of the energy storage device. A charging device is electrically connected to the charging port of the energy storage device through the second through-hole 115. (See also...) Figure 2 , Figure 2 The second through hole 115 is embedded and formed by a through hole mold insert.

[0064] In one embodiment, see Figure 1 , 3A second housing 120 is disposed on the surface of the first housing 110 opposite to the first opening 111. One end of the second housing 120 is flush with one end of the first housing 110, and the other end extends outward relative to the end of the first housing 110 to form an end face flush with the first opening 111. The end face is an extended surface formed by the second housing 120 relative to the first housing 110, and the extended surface forms the bone conduction surface 122. The extended surface, together with the side wall of the second housing 120 and the side wall of the first housing 110, forms the first receiving cavity 123. The first receiving cavity 123 includes a plurality of sub-cavities. The first receiving cavity 123 contains electronic components and / or bone conduction oscillators for processing mobile phone media sound.

[0065] In one embodiment, the first receiving cavity 123 may include three sub-cavities, namely a first sub-cavity, a second sub-cavity, and a third sub-cavity, which are arranged side by side and spaced apart. The bottom of each sub-cavity is flat, and a bone conduction vibrator is installed in the second sub-cavity. The second housing 120 also has a second receiving cavity 124, which is spaced apart from the first receiving cavity 123 and is located in the middle of the first housing 110. The bottom of the second receiving cavity 124 is provided with an adhesive inlet 125, which is connected to an external device.

[0066] This invention provides a bone conduction phone case. The second shell of the phone case is configured to form an electronic component chamber, and the bottom plane of the second shell forms a bone conduction surface that contacts the human skull. The sound from the phone's media is processed by the electronic components in the electronic component chamber and then conducted to the human skull through the bottom plane of the second shell. Therefore, the phone case provided by this invention can not only process the sound from the phone's media, but also transmit the processed sound directly to the human skull through the bone conduction surface, thereby reducing sound loss.

[0067] Furthermore, in the mobile phone case provided by the present invention, one end of the second shell is flush with one end of the first shell, and the other end extends outward relative to the end of the first shell to form an end face flush with the first opening. The end face is the extended surface formed by the second shell relative to the first shell, and the extended surface forms the bone conduction surface. Therefore, the bone conduction surface of the mobile phone case of the present invention is actually extended relative to the mobile phone screen and disposed next to the earpiece. Thus, the bone conduction surface can directly contact the human skull.

[0068] Example 2

[0069] Based on the bone conduction phone case provided above, this invention provides a mold for manufacturing a bone conduction phone case, which includes a venting mold core insert 200. See also... Figure 4 ,5 The exhaust mold insert 200 includes an exhaust block 210, on which a plurality of exhaust plates 220 are provided. The plurality of exhaust plates 220 are arranged in a row at intervals on the surface of the exhaust block 210. An exhaust groove 230 is formed between two adjacent exhaust plates 220. An exhaust channel 240 is provided on one side of a row of exhaust plates 220. The exhaust channel 240 is arranged along the length direction of the row of exhaust plates 220. The length direction of the exhaust channel 240 is perpendicular to the length direction of the exhaust groove 230. The exhaust groove 230 communicates with the exhaust channel 240. The exhaust mold insert 200 is configured to cooperate with the molding die of the bone conduction mobile phone shell 100 to realize the conduction and discharge of gas in the molding die.

[0070] See Figure 5 The venting mold insert is provided with a venting block, which includes several venting plates. A venting groove is formed between the sides of every two adjacent venting plates. A venting channel is provided at the lower end of each venting plate. Each channel is connected to form an integrally connected venting channel. The integrally connected venting channel is connected to an venting pipe to discharge trapped air in the mold.

[0071] In one embodiment, the venting insert 200 is a long column structure, and one end of the venting insert 200 has a protrusion that forms the venting block 210. The shape and size of the venting block 210 match the shape and size of the first receiving cavity 123 on the molding die used to form the bone conduction surface 122.

[0072] In one embodiment, the first receiving cavity 123 of the molding die 300 for the bone conduction phone case includes three sub-cavities, and the end of the venting core insert 200 that matches the molding die includes three venting blocks 210, one of the venting blocks 210 being received in one of the sub-cavities, and the three venting blocks 210 being arranged adjacently at intervals.

[0073] In one embodiment, see Figure 5 The three exhaust blocks 210 are respectively a first exhaust block 211, a second exhaust block 212, and a third exhaust block 213. The second exhaust block 212 is disposed between the first exhaust block 211 and the third exhaust block 213, and the cross-sectional area of ​​the second exhaust block 212 is larger than that of the first exhaust block 211 and the third exhaust block 213. The sub-chamber corresponding to the second exhaust block 212 is configured to accommodate electronic components and / or bone conduction transducers for processing mobile phone media sound. The bottom of the sub-chamber is disposed opposite to the bone conduction surface 122 of the bone conduction mobile phone housing 100.

[0074] In one embodiment, see Figure 6 The surface of the first exhaust block 211 210 is provided with a plurality of exhaust plates 220. The plurality of exhaust plates 220 are arranged in a row on the surface of the first exhaust block 211 210. The width of the exhaust groove 230 formed between two adjacent exhaust plates 220 is 0.035mm. The exhaust channel 240 on the first exhaust block 211 210 is connected to the exhaust groove 230.

[0075] In one embodiment, see Figure 6 The surface of the second exhaust block 212 210 is provided with a plurality of exhaust plates 220, and the plurality of exhaust plates 220 are arranged in a row on the surface of the second exhaust block 212 210. The width of the exhaust groove 230 formed between two adjacent exhaust plates 220 is 0.015mm, and the exhaust through groove 240 on the second exhaust block 212 210 is connected to the exhaust groove 230.

[0076] It is worth mentioning that on the exhaust block corresponding to the second sub-chamber, the sides of every two adjacent exhaust plates form an exhaust groove with a width of 0.015mm to ensure that the gap between each plate is not too large and will cause flash in the product. The exhaust groove between the exhaust plates on the exhaust blocks corresponding to the first and third sub-chambers has a width of 0.035mm. This area has no functional or aesthetic requirements, so the exhaust should be made as large as possible to ensure smooth exhaust.

[0077] In one embodiment, see Figure 7 The venting plate 220 has a fixed end 221, which extends from the surface of the venting block 210 toward the other end of the venting mold core insert 200, so that the fixed end 221 is fixedly connected to the venting mold core insert 200. The fixed end 221 includes a mounting platform 222, and the end of the venting mold core insert 200 connected to the fixed end 221 has a mounting hole 250. The mounting platform 222 of the venting plate 220 extends from the surface of the venting block 210 toward the mounting hole 250, so that the mounting platform 222 is engaged in the mounting hole 250. That is, the venting plate is fixed to the mold core insert by the mounting platform, and the end is fixed to the mold core, which facilitates installation and fixation.

[0078] In another embodiment, see continue to see Figure 7 A fixed base is provided on the exhaust mold insert 200 connected to the fixed end 221. The mounting platform 222 of the exhaust plate 220 extends from the surface of the exhaust block 210 toward the fixed base. The mounting platform 222 of the exhaust plate 220 is fixed on the fixed base by a pin 260.

[0079] The mold for manufacturing a bone conduction phone case provided by this invention includes a venting insert. The insert assists in venting during phone case molding, expelling trapped air from the mold to ensure a smooth molding surface and achieve good sound conduction. The second shell of the phone case produced by this mold has one end flush with one end of the first shell, and the other end extends outward relative to the end of the first shell to form an end face flush with the first opening. This end face is the extended surface formed by the second shell relative to the first shell, and it forms the bone conduction surface. Therefore, the bone conduction surface of the phone case of this invention is actually extended relative to the phone screen and positioned next to the earpiece, allowing the bone conduction surface to directly contact the human skull.
