Technical Field
[0001] The utility model relates to the technical field of electronic equipment, in particular to a sound-enhanced intelligent speaker. Background Art
[0002] A speaker is a device that can convert audio signals into sound. According to the principle of electroacoustics, the lower the frequency, the greater the vibration amplitude required, and a large vibration amplitude must be achieved by a large vibration unit. Therefore, in order to achieve the bass effect of the speaker, the speaker will be large in size, heavy in weight, and take up space, which does not meet the current people's pursuit of high quality of life, wanting to listen to music anytime, anywhere, and enjoy the relaxing and pleasant atmosphere brought by music.
[0003] In order to cater to people's pursuit, speakers have tended to be miniaturized in recent years. At the same time, miniaturized speakers need to use passive diaphragms to enhance the bass effect. However, the bass effect of existing miniaturized speakers is often inconsistent with the sound produced by the speaker, resulting in a very vague bass music effect of the speaker, which brings a very bad experience to users.
[0004] Therefore, the above technical problems need to be solved. Utility Model Content
[0005] In order to overcome the shortcomings of the prior art, the utility model proposes a sound-enhanced smart speaker that can effectively utilize the space in the speaker so that the speaker can achieve a bass effect while ensuring that the bass can accurately express the sound frequency generated by the speaker and thus produce a bass playback effect consistent with the sound frequency.
[0006] In order to solve the above technical problems, the basic technical solution proposed by the utility model is:
[0007] A sound-enhanced smart speaker comprises a speaker, a shell and a second diaphragm, the shell having a accommodating cavity, the accommodating cavity having a mesh cover, the mesh cover covering the opening of the accommodating cavity, the speaker being connected below the mesh cover, the concave portion of the first diaphragm included in the speaker facing the mesh cover; the second diaphragm is arranged in the accommodating cavity and located below the speaker, the concave portion of the second diaphragm facing oppositely to the concave portion of the first diaphragm.
[0008] Furthermore, the second diaphragm is coaxially arranged with the loudspeaker.
[0009] Furthermore, the distance between the highest point of the second diaphragm and the lowest point of the speaker is 5 cm-15 cm.
[0010] Furthermore, the orthographic projection of the second diaphragm can at least cover the orthographic projection of the loudspeaker.
[0011] Furthermore, the vibration direction of the second diaphragm is consistent with the vibration direction of the first diaphragm.
[0012] Furthermore, the second diaphragm is arranged in parallel with the first diaphragm.
[0013] Furthermore, an atmosphere light is arranged below the second diaphragm, and the light of the atmosphere light can be projected into the accommodating cavity through a portion of the second diaphragm.
[0014] Furthermore, a base is detachably connected to the bottom of the shell; a control processor and a battery are installed in the base; and the speaker is connected to the control processor via a power cord and is controlled by the control processor.
[0015] Furthermore, the power line passes through the accommodating cavity and may have a preset shape on the cavity wall of the accommodating cavity.
[0016] Furthermore, the power line located in the accommodating cavity has a second light-emitting portion.
[0017] The beneficial effects of the utility model are:
[0018] The utility model arranges the second diaphragm in the accommodating cavity and below the speaker, and the second diaphragm body presents an arched arc in the direction of the speaker. The direction of the second diaphragm toward the speaker is conducive to shortening the resonance cavity between the second diaphragm and the speaker, so that the second diaphragm can capture the sound wave frequency generated by the speaker in a limited space, so that the second diaphragm can accurately express the sound wave frequency of the speaker and achieve the same frequency as that of the speaker, and can accurately achieve a bass effect with the same frequency as that of the speaker in a limited space.

DETAILED DESCRIPTION
[0027] The following will be combined with the attached Figure 1 To Attachment Figure 6 The technical solutions in the embodiments of the utility model are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0028] It should be noted that if there are directions involved in the embodiments of the present invention, they shall be based on the directions shown in the drawings, such as front and rear. Figure 1 The specific Figure 1 The left side is the front, Figure 1 The right side is the back; at the same time Figure 2 As shown in the figure, the left-right direction is roughly the horizontal direction, and the up-down direction shown in the figure is the vertical direction. If a certain posture changes, the directional indication will also change accordingly.
[0029] The present inventor provides a sound-enhanced smart speaker, which fully utilizes the internal space of the miniaturized speaker while enabling the bass sounding area of the speaker to accurately express the sound produced by the speaker.
[0030] Specific as Figure 1 to Figure 2As shown, a sound-enhanced smart speaker includes a shell 2 and a base 3, wherein the base 3 is located below the shell 2 and is detachably connected to the shell 2. After the base 3 is assembled with the shell 2, the upper surface of the base 3 is placed in the shell 2, and the shell 2 has a receiving cavity 23. The upper surface of the base 3 is communicated with the receiving cavity 23 of the shell 2; in another direction opposite to the upper surface of the base 3, the receiving cavity 23 has an opening 231 leading to the outside, and the opening 231 has a mesh cover 1, and the mesh cover 1 is used to cover the opening 231. A speaker 21 is detachably connected below the mesh cover 1, and the speaker 21 is placed in the receiving cavity 23. The connection between the speaker 21 and the mesh cover 1 and the assembly with the base 3 make the receiving cavity 23 form a closed space.
[0031] When the speaker is playing music, the speaker 21 is controlled by the control processor 32 in the base 3, and under the action of the control processor 32, the first diaphragm 211 on the speaker 21 generates vibrations with the same frequency as the electromagnetic wave, thereby restoring the sound effect of the music. It is precisely because the accommodating cavity 23 is a closed space that the sound of the speaker 21 can be amplified in the accommodating cavity 23 and then transmitted from the mesh cover 1, thereby meeting the user's demand for amplified sound effects of music playback.
[0032] However, as users' demands for various sound effects played by speakers increase, especially for speakers that can provide bass sound effects that can bring stronger auditory impact to users, users' demand for bass speakers is increasing.
[0033] In this regard, Figure 1 to Figure 2 As shown, in the technical solution, a second diaphragm 22 is provided on the upper surface of the base 3 , the second diaphragm 22 is placed in the accommodating cavity 23 , and the base 3 is connected to the accommodating cavity 23 through the second diaphragm 22 .
[0034] Specifically, the second diaphragm 22 is a sound wave capturing membrane that is arched toward the middle part of the speaker 21. The second diaphragm 22 can capture the sound waves generated by the speaker 21 and perform secondary vibration processing on the sound waves to produce a sound with the same frequency as the sound waves and a bass effect. The sound is re-propagated in the accommodating cavity 23 and transmitted out from the mesh holes in the grille 1 to meet the user's demand for the bass effect of the speaker.
[0035] In summary, the speaker includes a speaker 21, a shell 2 and a second diaphragm 22, the shell 2 has a accommodating cavity 23, the accommodating cavity 23 has a mesh cover 1, the mesh cover 1 covers the opening 231 of the accommodating cavity 23, the speaker 21 is connected below the mesh cover 1, the recess 2111 of the first diaphragm 211 included in the speaker 21 faces the mesh cover 1; the second diaphragm 22 is arranged in the accommodating cavity 23 and is located below the speaker 21, and the second recess 221 of the second diaphragm 22 is opposite to the recess 2111 of the first diaphragm 211.
[0036] It should be understood that Figures 1 to 3 As shown, the second recess 221 of the second diaphragm 22 is in the opposite direction to the recess 2111 of the first diaphragm 211, that is, the arching direction of the second diaphragm 22 is opposite to the arching direction of the first diaphragm 211. This design is beneficial for the second diaphragm 22 to capture the sound wave frequency generated by the vibration of the first diaphragm 211. It should be noted that the sound generated by the loudspeaker 21 is generated by the vibration of the first diaphragm 211. Therefore, the second diaphragm 22 and the recessed parts of the first diaphragm 211 are arranged in opposite directions, so that the second diaphragm 22 can more easily and accurately capture the sound vibration sound waves generated by the first diaphragm 211, thereby generating a sound wave frequency consistent with the first diaphragm 211, so that the sound of the loudspeaker 21 can be further restored to a bass effect.
[0037] Also like Figure 1 As shown, in a preferred embodiment, further, the second diaphragm 22 is coaxially arranged with the speaker 21 .
[0038] It should be understood that since the speaker 21 and the second diaphragm 22 are in the same accommodating cavity 23, the interior of the accommodating cavity 23 is a vertical cylindrical hollow body, and the vibration frequency generated by the speaker 21, that is, the sound wave, collides with the cavity wall 232 of the accommodating cavity 23, and the sound wave rotates downward inside the accommodating cavity 23 until it touches the second diaphragm 22, and is absorbed by the second diaphragm 22 and converted into vibration kinetic energy, so the second diaphragm 22 can generate a vibration frequency consistent with the first diaphragm 211. Setting the second diaphragm 22 coaxially with the speaker 21 is conducive to the second diaphragm 22 fully absorbing and capturing the sound waves of the speaker 21, so as to fully restore the sound frequency.
[0039] Also like Figure 6 As shown, in another preferred embodiment, further, the height H between the highest point of the second diaphragm 22 and the lowest point of the speaker 21 is 5 cm-15 cm.
[0040] It should be understood that since the intensity of sound wave transmission is getting weaker and weaker, as the sound wave comes out from the end of the speaker 21, its propagation will become more and more diffuse and the intensity will become weaker and weaker. Therefore, setting the length of the highest point of the second diaphragm 22 to the lowest point of the speaker 21 between 5cm and 15cm is beneficial for the second diaphragm 22 to capture and absorb the sound wave, so as to accurately restore the sound of the speaker.
[0041] Also like Figure 1 As shown, in another preferred embodiment, further, the orthographic projection of the second diaphragm 22 can at least cover the orthographic projection of the speaker 21 .
[0042] It should be understood that during the transmission process, sound waves gradually diffuse outward from the concentration at the sound source, and the spiral area of sound wave transmission becomes larger and larger. Therefore, the orthographic projection area of the second diaphragm 22 can at least cover the orthographic projection area of the speaker 21, that is, the area of the second diaphragm 22 is larger than the area of the speaker 21. This design method allows the second diaphragm 22 to have sufficient area to absorb sound waves, thereby fully absorbing the sound waves in the accommodating cavity 23 to restore the bass sound effect consistent with the speaker 21.
[0043] Also like Figure 1 As shown, in another preferred embodiment, further, the vibration direction of the second diaphragm 22 is consistent with the vibration direction of the first diaphragm 211 .
[0044] It should be understood that this design method makes the sound waves in the accommodating cavity 23 propagate in a regular and orderly manner, so that after the sound waves come out of the speaker 21, they can propagate regularly in the direction of the second diaphragm 22. The second diaphragm 22 captures the sound waves and is affected by the transmission direction of the sound waves. The second diaphragm 22 maintains the same vibration direction as the first diaphragm 211. In addition to effectively enhancing the volume effect of the sound, this method can also make the sound quality effect clearer, bringing users a comfortable auditory enjoyment.
[0045] Also like Figure 1 As shown, in another preferred embodiment, further, the second diaphragm 22 and the first diaphragm 211 are arranged in parallel.
[0046] It should be understood that since the sound waves are transmitted in a positive downward direction after coming out of the speaker 21, the second diaphragm 22 is set in a parallel state with the first diaphragm 211. In this speaker, the surface of the second diaphragm 22 can contact the sound waves with the largest area, so that the second diaphragm 22 can absorb more sound waves to more accurately restore the sound effect of the speaker 21, thereby producing a precise bass effect.
[0047] Furthermore, an atmosphere light 31 is disposed below the second diaphragm 22 , and light from the atmosphere light 31 can be projected into the accommodating cavity 23 through a portion of the second diaphragm 22 .
[0048] When in use, the atmosphere light 31, under the control of the control processor 32, produces a lighting effect consistent with the sound effect of the speaker 21. The atmosphere light 31 can produce corresponding color changes according to the speed or volume of the sound to increase the user's interest in listening to music.
[0049] It should be noted that part of the material of the second diaphragm 22 is light-transmissive. Figure 3 As shown, the light-transmitting portion B, therefore, the light color change of the atmosphere lamp 31 can be projected from this part of the light-transmitting material to illuminate the accommodating cavity 23. The accommodating cavity 23 is made of transparent material, which is convenient for the user to observe the light change effect brought by the atmosphere lamp 31 through the accommodating cavity 23.
[0050] In another embodiment, the second diaphragm 22 may also be designed to be shaped like a snow mountain or a cone, so as to enrich the aesthetics of the speaker.
[0051] Furthermore, as described above, a base 3 is detachably connected to the bottom of the housing 2 ; in addition to being equipped with the above-mentioned atmosphere light 31 , the base 3 is also equipped with a control processor 32 and a battery 33 .
[0052] It can be understood that the atmosphere light 31 and the battery 33 are both controlled by the control processor 32. The battery 33 has a charging and discharging function, can store electrical energy for the sound playback of the speaker, and can also be used as a power source to charge external devices according to user needs.
[0053] In addition, Figure 5 As shown, a switch button 34 is also provided on the side or bottom of the base 3. The switch button 34 includes a volume adjustment button, a power switch button and a play pause button. The switch button 34 is electrically connected to the control processor 32. The user operates the switch button 34 to obtain the corresponding usage status of the speaker.
[0054] It should be noted that the speaker 21 is also controlled by the control processor 32, as shown in the following example. Figure 4 As shown, the speaker 21 is connected to the control processor 32 via a power line 4 and is controlled by the control processor 32 .
[0055] Furthermore, the power line 4 passes through the accommodating cavity 23 and may have a preset shape on the cavity wall 232 of the accommodating cavity 23 ; further, the power line 4 located in the accommodating cavity 23 has a second light-emitting portion 41 .
[0056] It should be noted that the second light emitting portion 41 may be disposed on the insulating layer of the power cord 4 . In some embodiments, some LED lamp components may be arranged on the insulating layer so that the power cord 4 produces a light emitting effect.
[0057] In some other embodiments, the insulating layer of the power line 4 is made of a luminescent material, which can also make the power line 4 produce a luminescent effect.
[0058] It should be noted that the power cord 4 can be fixed on the cavity wall 232 by gluing.
[0059] When the power cord 4 is coiled on the inner wall 232 of the accommodating cavity 23 in a certain pre-designed shape, since the accommodating cavity 23 is made of a transparent material, the user can observe various shapes of the power cord 4 with a luminous effect on the accommodating cavity 23 while enjoying the music. In addition to bringing auditory enjoyment to the user, this speaker can also bring visual enjoyment.
[0060] It should be noted that the detachable connection method described in this article can be not only the snap assembly connection, but also other detachable methods such as threaded connection.
[0061] In summary, the technical solution provides a sound-enhanced smart speaker, which is provided with a second diaphragm 22 inside. The second diaphragm 22 can capture the sound waves of the speaker 21 to produce a matching vibration frequency, and the protrusions of the second diaphragm 22 and the first diaphragm 211 in the speaker 21 are set relative to each other, thereby increasing the bass function of the speaker, and the second diaphragm 22 does not need to rely on external force to vibrate. It is made of some sound-sensitive materials and can effectively capture sound propagating in the air.
[0062] A sound-enhanced smart speaker of the present technical solution not only has a bass music playing effect, but also can be accompanied by an atmosphere light 31 that changes with the playing of the music, and the power cord 4 also has various shapes and patterns on the cavity wall 232 of the accommodating cavity 23, such as star patterns, circles, etc., so that the user's hearing and vision can be enjoyed at the same time.
[0063] According to the disclosure and teaching of the above description, the technical personnel in the field to which the utility model belongs can also change and modify the above implementation. Therefore, the utility model is not limited to the specific implementation methods disclosed and described above, and some modifications and changes to the utility model should also fall within the scope of protection of the claims of the utility model. In addition, although some specific terms are used in this specification, these terms are only for the convenience of description and do not constitute any limitation to the utility model.
