Description

Technical Field

[0001] The utility model relates to a speaker, in particular to a speaker with a dual sound system and a bone conduction earphone. Background Art

[0002] The speaker is the most important component in headphones. Currently, the main speakers on the market are bone conduction speakers and air conduction speakers. Bone conduction speakers convert electrical signals into mechanical vibrations of varying frequencies, transmitting sound waves through the skull, bony labyrinth, inner ear lymph, organ of the gyrus, and auditory center. The vibrations of bone conduction speakers are transmitted through transducers, which are typically made of stainless steel. As a result, bone conduction speakers are generally suited to high-frequency mechanical vibrations. Lower frequencies make it difficult for bone conduction speakers to produce clear sound. Furthermore, the vibrations of bone conduction speakers are more impactful on the skin, reducing the user experience. Air conduction speakers convert electrical signals into air vibrations. The resulting audio signal enters the ear through the external auditory canal, vibrates the eardrum, and is detected by the cochlea in the inner ear and transmitted to the auditory center. Air conduction headphones offer superior sound quality and can transmit low-frequency sounds, but they lack waterproofing. Utility Model Content

[0003] The utility model provides a dual-sound system speaker and bone conduction earphones, which are used to simultaneously solve the problems of poor low-frequency sound transmission effect and relatively large impact on the skin of bone conduction earphones, and poor waterproofness of air conduction earphones.

[0007] A second sound-producing system, comprising a vibrating membrane, is disposed within the accommodating space and fixedly connected to an end of the speaker housing away from the user. The second sound-producing system is an air-conduction sound-producing system configured to produce low-frequency sounds, wherein the low-frequency sounds are sounds having a frequency less than a set crossover point.

[0008] The vibration membrane seals the accommodating space into a sealed accommodating space.

[0019] Beneficial effects of the utility model:

[0020] The utility model arranges two sets of dual sound systems in one speaker, namely the first sound system and the second sound system. The first sound system is a bone conduction sound system, and the first sound system is used to emit high-frequency sounds. The second sound system is an air conduction sound system, and the second sound system is used to emit low-frequency sounds. When the frequency of the received signal is not less than the frequency of the set crossover point, the first sound system works to emit sound.

DETAILED DESCRIPTION

[0033] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0034] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0035] In the present invention, unless otherwise specified, directional words such as "up, down, top, bottom" are usually used with reference to the directions shown in the drawings, or with reference to the components themselves in the vertical, perpendicular or gravity direction; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above directional words are not used to limit the present invention.

[0036] See also Figure 1 and Figure 9 As shown, according to one aspect of the present invention, a bone conduction earphone 100 is provided, in which a dual sound system speaker 110 is provided, including:

[0037] Speaker housing 1; an accommodating space is provided in the speaker housing 1, and the accommodating space is provided with an opening at least at one end away from the user.

[0038] The first sound system is arranged in the accommodating space. The first sound system is fixedly connected to the end of the speaker housing 1 close to the user. The first sound system is a bone conduction sound system. The first sound system is used to emit high-frequency sound. The high-frequency sound is a sound with a frequency not less than the set crossover point.

[0039] The second sound system includes a vibration membrane 31. The second sound system is arranged in the accommodating space. The vibration membrane 31 is fixedly connected to the end of the speaker housing 1 away from the user. The second sound system is an air conduction sound system. The second sound system is used to emit low-frequency sound. The low-frequency sound is a sound with a frequency less than the set crossover point.

[0040] The vibration membrane 31 seals the accommodating space, making the accommodating space a closed space, and the speaker has a sealing and waterproof effect.

[0041] The vibration membrane 31 can be set to be circular, oval, square and rectangular, etc. Preferably, the vibration membrane 31 is circular, and the periphery of the vibration membrane 31 is fixedly connected to the end of the speaker housing 1 away from the user. The material of the vibration membrane 31 is a flexible material, preferably silicone.

[0042] The vibration membrane 31 and the speaker housing 1 can be an integrated structure. For example, the vibration membrane 31 and the speaker housing 1 can be injected together to form an integrated structure. The integrated structure has extremely high sealing performance and can fundamentally prevent liquid from flowing into the earphones. Therefore, the earphones can easily reach the highest level of IPX8 waterproof level.

[0043] To save costs and facilitate future replacement, the diaphragm 31 and speaker housing 1 can also be made into a split structure. For example, the periphery of the diaphragm 31 can be fixed to the speaker housing 1, and the two can be fixed together by glue. Alternatively, the periphery of the diaphragm 31 can be nested in a plastic part, which is then clipped onto the speaker housing 1, and a sealing strip is used to seal the plastic part and the speaker housing 1. By using a split structure and adopting certain sealing measures, the headphones can also achieve a higher waterproof level, even the high-level IPX8 waterproof level.

[0044] A crossover is also provided in the earphones, which are electrically connected to the first sound system and the second sound system respectively. The crossover point of the crossover can be set. For example, the frequency of the crossover point can be set to any value in the range of 200Hz to 600Hz, preferably between 200Hz and 500Hz, and further preferably between 300Hz and 500Hz.

[0045] For example, the crossover frequency point of the crossover can be set to 300Hz. When an external input signal is input into the crossover, if the external input signal is greater than or equal to 300Hz, the external input signal is input into the first sound system through the crossover, and the first sound system works, while the second sound system does not work. If the external input signal is less than 300Hz, the external input signal is input into the second sound system through the crossover, and the second sound system works, while the first sound system does not work. Of course, the crossover frequency point can be set to other values, such as 400Hz or 500Hz, and can be selected according to needs.

[0046] Users can also control the crossover frequency through an APP mini-program. Users can download the corresponding APP mini-program on a mobile terminal, such as a mobile phone. After a user purchases a new bone conduction headset 100 with a dual sound system speaker 110, a crossover frequency point is preset in the bone conduction headset 100. When the user wants to change the crossover frequency point, the user only needs to connect the phone and headset via Bluetooth and open the APP mini-program on the phone. The APP mini-program on the phone will display the current crossover frequency point. The user only needs to enter the desired crossover frequency point and click Confirm to set the new crossover frequency point. The user can set the crossover frequency point repeatedly as needed, and the crossover frequency point will be updated repeatedly.

[0047] This embodiment incorporates two dual sound systems within a single speaker: a first sound system and a second sound system. The first system is a bone conduction sound system, emitting high-frequency sounds, while the second system is an air conduction sound system, emitting low-frequency sounds. When an external signal is input to a frequency divider, the frequency divider compares the frequency of the external signal with a set crossover frequency. If the external signal's frequency is at least the crossover frequency, the signal is fed through the frequency divider to the first sound system, which transmits the sound signal to the user via bone conduction. If the external signal's frequency is less than the crossover frequency, the signal is fed through the frequency divider to the second sound system, which transmits the sound signal to the user via air conduction. This dual sound system solves the problem of bone conduction speakers struggling to clearly produce low-frequency sounds and avoids the harsh vibrations of bone conduction speakers at low frequencies, thereby improving the user experience.

[0048] By fixing and sealing the vibration membrane 31 to the end of the accommodating space away from the user, the problem of water leakage in a water environment of the air conduction sound system, which affects the function of the air conduction sound system, is avoided.

[0049] This embodiment expands the frequency range of the earphones by setting up two dual sound systems, while also having a waterproof function, and has a wider range of usage scenarios.

[0050] In one embodiment, see Figure 2 As shown, the end of the speaker housing 1 facing away from the user is provided with a protective portion 11. Protective portion 11 is located on the side of the diaphragm 31 facing away from the user. The diaphragm 31 is made of a flexible material, typically silicone, but can also be made of other elastic materials such as rubber or silicone rubber. Because the diaphragm 31 is flexible, the user's hand may come into contact with it while using the headphones, thereby affecting the sound produced by the air conduction speaker and affecting the speaker's function. By providing protective portion 11 on the side of the diaphragm 31 facing away from the user, the user's hand is prevented from directly contacting the diaphragm 31, thereby protecting the air conduction speaker.

[0051] In one embodiment, see Figure 3As shown, the dual-sound system speaker 110 further includes a speaker cover 5, which is fixedly mounted on the end of the speaker housing 1 away from the user and is located on the outside of the diaphragm 31. In order to further protect the diaphragm 31, the speaker cover 5 is provided to cover the diaphragm 31, which can better prevent human hands from touching the diaphragm 31. At the same time, since the diaphragm 31 is a vibrating component and is exposed to the outside for a long time, dust or other dirt will accumulate on the diaphragm 31. Dust or other dirt attached to the diaphragm 31 will cause the vibration frequency of the diaphragm 31 to change, affecting the sound quality. By providing the speaker cover 5, dust and other dirt can be prevented from adhering to the diaphragm 31.

[0052] In order to effectively transmit the sound of the air conduction speaker, a plurality of penetrating sound transmission holes 51 are provided on the speaker cover 5 so that the sound can be effectively transmitted.

[0053] In one embodiment, see Figure 1 As shown, the first sound-emitting system includes a panel 21, a vibration-transmitting plate 26, a fixing member 27, a coil bracket 23, a first coil 22, a first magnet 24 and a first magnetic conductive plate 25. The center of the vibration-transmitting plate 26 is fixedly connected to the panel 21 through the fixing member 27, and the periphery of the vibration-transmitting plate 26 is fixedly connected to the inner wall of the through hole in the middle of the coil bracket 23. The first coil 22 is fixedly arranged on the coil bracket 23, and the first coil 22 is located between the first magnet 24 and the wall of the speaker housing 1.

[0054] The panel 21 and the speaker housing 1 can be an integral part or two independent parts. When the panel 21 and the speaker housing 1 are two independent parts, the panel 21 and the speaker housing 1 are fixed and sealed. Figure 5 As shown, the sealing of the accommodating space is ensured, so that the speaker has a higher waterproof level.

[0055] The second sound-generating system further includes a second coil 32 , a second magnet 34 and a second magnetic conductive plate 35 . The second coil 32 is fixedly connected to the vibration membrane 31 . The second coil 32 is located between the second magnet 34 and the wall of the speaker housing 1 .

[0056] The dual-sound system speaker 110 also includes a magnet fixing plate 4, which is arranged in the accommodating space. The magnet fixing plate 4 is fixedly connected to the inner wall of the accommodating space in the speaker housing 1. The first magnet 24 and the second magnet 34 are respectively fixed on both sides of the magnet fixing plate 4. The first magnetic conductive plate 25 is fixed on the first magnet 24, and the second magnetic conductive plate 35 is fixed on the second magnet 34.

[0057] By fixing the first magnet 24 and the second magnet 34 on the magnet fixing plates 4 respectively, the number of magnet fixing plates 4 can be reduced, and the volume of the speaker can be reduced at the same time.

[0058] See also Figures 2 to 5 As shown, the first magnet 24 and the second magnet 34 are formed into a single unit. This integration further reduces the size of the speaker and simplifies assembly. The magnet fixing plate 4 is secured to the slots provided on the unitary magnet, further simplifying the assembly process.

[0059] In one embodiment, the area of the vibration membrane 31 has different sensitivities to sound. Generally speaking, a vibration membrane 31 with a larger area pushes a larger volume of air. In terms of sound effects, a vibration membrane 31 with a larger area produces better sound effects for low-frequency signals. Therefore, increasing the area of the vibration membrane 31 can improve the low-frequency effect.

[0060] In order to achieve higher sound quality, the area of the vibration membrane 31 is enlarged while the thickness of the vibration membrane 31 is increased, which can further ensure the bass effect.

[0061] In one embodiment, a counterweight 33 is provided on the side of the diaphragm 31 away from the user. Providing the counterweight 33 on the diaphragm 31 can reduce the vibration frequency of the diaphragm 31, making the bass effect of the air conduction speaker more obvious.

[0062] The counterweight 33 and the vibration membrane 31 can be integrally provided and made of the same material, such as silicone material.

[0063] The counterweight 33 and the vibration membrane 31 can be split. The vibration membrane 31 is made of silicone material, and the counterweight 33 is made of a different material. The material of the counterweight 33 can be metal, plastic, silicone, etc. The user can choose a suitable counterweight 33 according to the bass effect he wants to achieve. The heavier the counterweight 33, the more obvious the bass effect.

[0064] The contact area between the counterweight 33 and the vibration membrane 31 also affects the sound quality. The larger the contact area between the counterweight 33 and the vibration membrane 31, the better the sound quality of the air conduction speaker.

[0065] In one embodiment, see Figures 6-8 As shown, the circular speaker housing 1 includes an upper speaker housing 13 and a lower speaker housing 12 , and the outer diameters of the lower speaker housing 12 and the upper speaker housing 13 are the same.

[0066] A circular first space 29 is coaxially arranged in the lower speaker housing 12, and one end of the first space 29 is open. A first groove 121 with one end open is provided on the side wall of the lower speaker housing 12. The opening direction of the first groove 121 is the same as the opening direction of the first space 29. A first inner wall 20 is formed between the first groove 121 and the first space 29. The height of the first inner wall 20 is less than the height of the side walls at other positions of the lower speaker housing 12.

[0067] The circular first coil 22 is coaxially fixed at the bottom of the first groove 121. The first magnetizing component 28 is circular and has a diameter larger than the first coil 22. The first magnetizing component 28 is fixedly connected to the inner side of the first inner wall 20. The spacing between the first magnetizing component 28 and the first coil 22 is uniform.

[0068] A circular second space 37 is coaxially arranged in the upper shell 13 of the speaker. A second groove 131 with one end open is provided on the side wall of the first end of the upper shell 13 of the speaker. A second inner wall 30 is formed between the second groove 131 and the second space 37. The height of the second inner wall 30 is less than the height of the side walls at other positions of the upper shell 13 of the speaker.

[0069] A third groove 38 is provided at the other end of the speaker upper housing 13. The third groove 38 and the second space 37 form a concentric circle. The edges of the diaphragm 31 are glued to the bottom of the third groove 38, leaving the center of the diaphragm 31 suspended in the air. This ensures that the diaphragm 31 does not interfere with the speaker upper housing 13 when vibrating. In this embodiment, the counterweight 33 is integrally formed with the diaphragm 31 and is made of silicone.

[0070] The circular second coil 32 is coaxially fixed on the inner side of the vibration membrane 31. The second magnetizing component 36 is circular and has a diameter larger than the second coil 32. The second magnetizing component 36 is fixedly connected to the inner side of the second inner wall 30. The spacing between the second magnetizing component 36 and the second coil 32 is uniform.

[0071] The first and second magnetizers 28 and 36 increase the intensity of the magnetic flux. They can be magnets or other materials that increase the magnetic flux, such as iron-silicon alloys or iron-aluminum alloys. Increasing the intensity of the magnetic flux increases the vibration amplitude of the coil and magnets, thereby boosting the volume.

[0072] The first end of the speaker upper shell 13 and the open end of the speaker lower shell 12 are fixedly connected. The two can be connected by glue or by snap connection. If snap connection is adopted, a sealing strip is provided between the speaker upper shell 13 and the speaker lower shell 12 to increase the sealing. When the speaker upper shell 13 and the speaker lower shell 12 are assembled together, the first space 29 and the second space 37 are connected and form the accommodating space in the speaker housing 1.

[0073] When the speaker lower shell 12 and the speaker upper shell 13 are glued together, and when the magnet fixing plate 4 is fixed with glue, the first groove 121 and the second groove 131 serve to collect excess glue. The excess glue is collected by the first groove 121 and the second groove 131 to prevent it from entering the first space 29 or the second space 37, affecting the movement of the coil and the magnet, and resulting in poor sound quality.

[0074] When the speaker upper shell 13 and the speaker lower shell 12 are assembled together, the axis of the first coil 22 and the axis of the second coil 32 are coaxial, there is a certain space between the first coil 22 and the second coil 32, and the magnet fixing plate 4 is arranged between the first coil 22 and the second coil 32.

[0075] The first magnet 24 and the second magnet 34 are an integral magnet. The first magnetic conductive plate 25 is fixedly set on one side of the integral magnet (on the first magnet 24), and the second magnetic conductive plate 35 is fixedly set on the other side of the integral magnet (on the second magnet 34). A slot is set in the middle position of the integral magnet, and the magnet fixing plate 4 is clamped with the slot. A fixing slot is set between the upper shell 13 of the speaker and the lower shell 12 of the speaker, and the magnet fixing plate 4 is fixedly connected to the fixing slot by glue.

[0076] The diameter of the integral magnet is smaller than the diameter of the first coil 22 and the second coil 32. After the integral magnet is assembled into the dual-sound system speaker, the integral magnet and the first coil 22 and the second coil 32 are coaxial, the first magnetic conductive plate 25 and a portion of the first magnet 24 are located in the first coil 22, and the second magnetic conductive plate 35 and a portion of the second magnet 34 are located in the second magnet 34.

[0077] A cable hole 14 is provided between the upper speaker housing 13 and the lower speaker housing 12. The conductive wires for the first and second sound systems pass through this hole to connect to an external circuit board or battery. When the dual-sound system speaker is assembled into the bone conduction earphone 100, the cable hole 14 is covered and sealed by other components, ensuring a sealed enclosure. This prevents water from leaking into the dual-sound system speaker, ensuring a high level of waterproofing.

[0078] In this embodiment, by directly and securely connecting the first coil 22 to the bottom of the first groove 121 and the second coil 32 to the inner side of the diaphragm 31, the height of the dual-sound system speaker 110 can be minimized. This also reduces the energy loss during vibration transmission and increases the volume.

[0079] In this embodiment, the first magnetizing member 28 and the second magnetizing member 36 are provided to further increase the intensity of the magnetic flux, thereby increasing the vibration amplitude of the coil and the magnet, and further increasing the volume.

[0080] In all the above embodiments, the three-dimensional shape of the dual-sound system speaker 110 can be circular, square, rectangular, elliptical, or other shapes. As long as the technical solution of the present invention can be implemented, it falls within the scope of protection of the present invention.

[0081] A bone conduction earphone 100, see Figure 9 As shown, a dual sound system speaker 110 according to one of the above embodiments is provided in the bone conduction earphone 100 .
