Description

Technical Field

[0001] The invention relates to a speaker, in particular to a double sound system speaker and a bone conduction earphone. Background Art

[0002] The speaker is the most important part of the headset. The speakers on the market mainly include bone conduction speakers and air conduction speakers. Bone conduction speakers convert electrical signals into mechanical vibrations of different frequencies and transmit sound waves through the human skull, bony labyrinth, inner ear lymph, spiral organ, and auditory center. The vibration of the bone conduction speaker is transmitted through the vibration plate, which is generally made of stainless steel. As a result, the bone conduction speaker is generally suitable for high-frequency mechanical vibrations. If the frequency is relatively low, it is difficult for the bone conduction speaker to produce a clear sound. At the same time, the vibration of the bone conduction speaker has a relatively large impact on the skin, which reduces the user experience. The air conduction speaker converts the electrical signal into air vibration, and the formed audio signal enters the human ear through the external auditory canal. After vibrating the eardrum, the audio signal is detected by the cochlea of ​​the inner ear and transmitted to the auditory center. Air conduction headphones have good sound quality and can transmit low-frequency sounds, but the waterproof effect of air conduction headphones is poor. Summary of the invention

DETAILED DESCRIPTION

[0017] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present 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.

[0018] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0019] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity directions; 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-mentioned directional words are not used to limit the present invention.

[0020] See also Figure 1 and Fig. 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: 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.

[0021] 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, and the first sound system is used to emit high-frequency sound, and the high-frequency sound is a sound with a frequency not less than a set crossover point.

[0022] The second sound system includes a vibration membrane 31, which 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, which is a sound with a frequency less than a set crossover point.

[0023] The vibration membrane 31 seals the accommodation space, making the accommodation space a closed space, and the speaker has a sealing and waterproof effect.

[0024] The vibration membrane 31 can be set to be circular, oval, square, 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.

[0025] 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 injection molded together to form an integrated structure. The integrated structure has extremely high sealing performance and can fundamentally prevent liquid from flowing into the earphone. Therefore, the earphone can easily reach the highest level of IPX8 waterproof level.

[0026] In order to save costs and facilitate future replacement, the vibration membrane 31 and the speaker housing 1 can also be made into a split structure, for example, the periphery of the vibration membrane 31 is fixed to the speaker housing 1, and the two can be fixed together by glue. The periphery of the vibration membrane 31 can also be nested in a plastic part, and then the plastic part is clamped on the speaker housing 1, and the plastic part and the speaker housing 1 are sealed by a sealing strip. Through the split structure and the use of certain sealing measures, the earphones can also achieve a higher waterproof level, even a high-level IPX8 waterproof level.

[0027] A crossover is also provided in the earphone, which is 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.

[0028] For example, the crossover frequency of the crossover can be set to 300Hz, and the 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, and 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, and the first sound system does not work. Of course, the crossover frequency can be set to other values, such as 400Hz or 500Hz, and can be selected according to needs.

[0029] The user can also control the crossover point through the APP applet. The user can download the corresponding APP applet on the mobile terminal, such as downloading it on the mobile phone. After the user purchases a new bone conduction headset 100 with a dual sound system speaker 110, a crossover point has been preset in the bone conduction headset 100. When the user wants to change the value of the crossover point, the user only needs to connect the mobile phone and the headset via Bluetooth and open the APP applet on the mobile phone. The APP applet on the mobile phone will display the current crossover point. The user only needs to enter a desired crossover point and click Confirm, and the new crossover point is set. The user can set the crossover point repeatedly according to his needs, and the crossover point will be updated repeatedly.

[0030] In this embodiment, two sets of dual sound systems are set 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 sound. The second sound system is an air conduction sound system, and the second sound system is used to emit low-frequency sound. When the external input signal is input to the crossover, the crossover compares the frequency of the external input signal with the frequency of the set crossover point. If the frequency of the external input signal is not less than the frequency of the crossover point, the external input signal will be input to the first sound system through the crossover, and the first sound system will transmit the sound signal to the user through bone conduction. If the frequency of the external input signal is less than the frequency of the crossover point, the external input signal will be input to the second sound system through the crossover, and the second sound system will transmit the sound signal to the user through air conduction. Through the two sound systems, the problem that the bone conduction speaker is difficult to clearly emit low-frequency sound is solved, and at the same time, the problem that the vibration of the bone conduction speaker at low frequencies has a relatively large impact on the skin is avoided, thereby improving the user experience.

[0031] The vibration membrane 31 is fixedly and sealedly connected to the end of the accommodating space away from the user, thereby avoiding the problem that the air conduction sound system is prone to leakage in a water environment, thereby affecting the function of the air conduction sound system.

[0032] This embodiment expands the frequency range of the earphone by setting up two sets of dual sound systems, while also having a waterproof function, and has a wider range of usage scenarios.

[0033] In one embodiment, see Figure 2 As shown, a protective portion 11 is provided at one end of the speaker housing 1 away from the user, and the protective portion 11 is provided on the side of the vibration membrane 31 away from the user. The vibration membrane 31 is made of a flexible material, generally a silicone material, or other elastic materials, such as rubber, silicone rubber, etc. Since the vibration membrane 31 is made of a flexible material, the user's hand may touch the vibration membrane 31 during the use of the headset, thereby affecting the sound of the air conduction speaker and affecting the function of the speaker. By providing the protective portion 11 on the side of the vibration membrane 31 away from the user, the user's hand can be prevented from directly contacting the vibration membrane 31, thereby protecting the air conduction speaker.

[0034] In one embodiment, see Figure 3As shown, the dual sound system speaker 110 also includes a speaker cover 5, which is fixedly arranged at the end of the speaker housing 1 away from the user and is located on the outside of the vibration membrane 31. In order to further protect the vibration membrane 31, the speaker cover 5 is arranged to cover the vibration membrane 31, which can better prevent the vibration membrane 31 from being touched by human hands. At the same time, since the vibration membrane 31 is a vibrating part and is exposed to the outside for a long time, dust or other dirt will accumulate on the vibration membrane 31. The dust or other dirt attached to the vibration membrane 31 will change the vibration frequency of the vibration membrane 31 and affect the sound quality. By setting the speaker cover 5, dust and other dirt can be prevented from being attached to the vibration membrane 31.

[0035] 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.

[0036] 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.

[0037] 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 fixedly and sealedly connected. Figure 5 As shown, the sealing of the accommodating space is ensured, so that the speaker has a higher waterproof level.

[0038] 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 .

[0039] 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 fixedly arranged on the first magnet 24, and the second magnetic conductive plate 35 is fixedly arranged on the second magnet 34.

[0040] By fixing the first magnet 24 and the second magnet 34 on the magnet fixing plate 4 respectively, the number of the magnet fixing plates 4 can be reduced, and the volume of the speaker can be reduced at the same time.

[0041] See also Figures 2 to 5 As shown, the first magnet 24 and the second magnet 34 are an integral magnet. The first magnet 24 and the second magnet 34 are an integral magnet, which can further reduce the volume of the speaker and simplify the assembly steps. The magnet fixing plate 4 is connected to the slot by providing a slot on the integral magnet, which can further simplify the assembly process.

[0042] 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.

[0043] In order to achieve higher sound quality, the area of ​​the vibration membrane 31 is enlarged and the thickness of the vibration membrane 31 is increased, which can further ensure the bass effect.

[0044] 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, and the bass effect of the air conduction speaker is more obvious.

[0045] The counterweight 33 and the vibration membrane 31 can be integrally provided and made of the same material, such as silicone material.

[0046] 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.

[0047] The contact area between the counterweight block 33 and the vibration membrane 31 also affects the sound quality. The larger the contact area between the counterweight block 33 and the vibration membrane 31, the better the sound quality of the air conduction speaker.

[0048] In one embodiment, see Figures 6 to 8 As shown, the circular speaker housing 1 comprises 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.

[0049] A circular first space 29 is coaxially arranged in the lower speaker shell 12, and one end of the first space 29 is open. A first groove 121 with one end open is arranged on the side wall of the lower speaker shell 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, and the height of the first inner wall 20 is less than the height of the side walls at other positions of the lower speaker shell 12.

[0050] The circular first coil 22 is coaxially fixedly arranged 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, and the spacing between the first magnetizing component 28 and the first coil 22 is uniform.

[0051] A circular second space 37 is coaxially arranged in the speaker upper shell 13, and a second groove 131 with an open end is arranged on the side wall of the first end of the speaker upper shell 13. A second inner wall 30 is formed between the second groove 131 and the second space 37, and the height of the second inner wall 30 is less than the height of the side walls at other positions of the speaker upper shell 13.

[0052] The other end of the speaker upper shell 13 is provided with a third groove 38, and the third groove 38 and the second space 37 are concentric circles. The edges of the vibration membrane 31 are fixed to the bottom of the third groove 38 by glue, and the middle of the vibration membrane 31 is suspended in the air. When the vibration membrane 31 vibrates, it will not interfere with the speaker upper shell 13. The counterweight block 33 and the vibration membrane 31 in this embodiment are integrally arranged, and the material is silicone.

[0053] 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.

[0054] The function of the first magnetizing component 28 and the second magnetizing component 36 is to increase the intensity of the magnetic flux. The first magnetizing component 28 and the second magnetizing component 36 can be magnets, or iron-silicon alloys and iron-aluminum alloys that increase the magnetic flux. By increasing the intensity of the magnetic flux, the vibration amplitude of the coil and the magnet can be increased, thereby increasing the volume.

[0055] 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-fit. If the snap-fit ​​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 constitute the accommodating space in the speaker housing 1.

[0056] 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.

[0057] 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.

[0058] The first magnet 24 and the second magnet 34 are an integral magnet, the first magnetic conductive plate 25 is fixedly arranged on one side of the integral magnet (on the first magnet 24), and the second magnetic conductive plate 35 is fixedly arranged on the other side of the integral magnet (on the second magnet 34). A slot is arranged in the middle of the integral magnet, and the magnet fixing plate 4 is engaged with the slot. A fixing slot is arranged between the speaker upper shell 13 and the speaker lower shell 12, and the magnet fixing plate 4 is fixedly connected with the fixing slot by glue.

[0059] 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.

[0060] A wire hole 14 is provided between the upper shell 13 and the lower shell 12 of the speaker. The conductive wires of the first sound system and the second sound system pass through the wire hole 14 and are electrically connected to an external circuit board or battery. When the dual sound system speaker is assembled on the bone conduction earphone 100, the wire hole 14 will be covered and sealed by other parts to ensure that the accommodating space is a closed space. The dual sound system speaker will not leak water and has a high waterproof level.

[0061] In this embodiment, the height of the dual sound system speaker 110 can be reduced to the maximum extent by directly and fixedly connecting the first coil 22 to the bottom of the first groove 121 and directly and fixedly connecting the second coil 32 to the inner side of the vibration membrane 31. At the same time, the energy loss during the vibration transmission process is reduced, and the volume is increased.

[0062] In this embodiment, the intensity of the magnetic flux is further increased by providing the first magnetizing member 28 and the second magnetizing member 36, so that the vibration amplitude of the coil and the magnet can be increased, and the volume can be further increased.

[0063] 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 belongs to the protection scope of the present invention.
