Description

Technical Field

[0001] The utility model relates to the technical field of musical instruments, in particular to a sound pickup device and an integrated electronic kazoo. Background Art

[0002] The kazoo is a very special wind instrument. It drives the resonance of the kazoo diaphragm through the sound emitted by human vocal humming, and further amplifies the sound through the air duct. The kazoo belongs to the aerophone in wind instruments. As long as the performer can hum a song, he can play the kazoo. The electronic kazoo is a new type of kazoo developed in recent years, and the sound pickup device is a very important part in the electronic kazoo.

[0003] The sound pickup assembly includes a pickup and a diaphragm. The pickup is used to collect the sound emitted by the vibration of the diaphragm. According to the different installation positions of the pickup, the sound pickup assembly can be divided into two types: external type and internal type. The external sound pickup assembly refers to installing the pickup on the outside of the kazoo body. Although this installation method is simple, it has the defects of insecure installation and being easily interfered by external sounds; the internal sound pickup assembly refers to installing the pickup inside the kazoo body. Although this installation method can reduce the external sound interference, its installation is more cumbersome, and it is easy to record the user's breathing sound. Moreover, the gas exhaled by the user is relatively humid, and the internal pickup will be affected by water vapor.

[0004] In addition, most of the existing electronic kazoos need to be used with an external speaker or horn. Some electronic kazoos have built-in speakers.

[0034] For the convenience of understanding the present utility model, the present utility model will be described more comprehensively below with reference to the relevant drawings. Those familiar with this technology can easily understand other advantages and effects of the present utility model from the content disclosed in this specification. It should be noted that the structures, ratios, sizes, etc. shown in the drawings of this specification are only used to cooperate with the content disclosed in the specification for those familiar with this technology to understand and read, and are not used to limit the limiting conditions under which the present utility model can be implemented. Therefore, they do not have substantial technical significance. Any modification of the structure, change of the proportional relationship or adjustment of the size, without affecting the effects that the present utility model can produce and the purposes that can be achieved, should still fall within the scope covered by the technical content disclosed in the present utility model. At the same time, the terms such as "upper", "lower", "left", "right" and "middle" cited in this specification are only for the convenience of clear narration, and are not used to limit the scope under which the present utility model can be implemented. The change or adjustment of their relative relationships, without substantial change in the technical content, should also be regarded as the scope under which the present utility model can be implemented.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present utility model belongs. The terms used in the specification of the present utility model herein are only for the purpose of describing specific embodiments, and are not intended to limit the present utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0036] The present utility model provides a sound pickup device 100, as Figure 1 and Figure 2 shown, which includes: a base 110, an outer housing 120, a fixing member 130, a sound pickup 140, and an inner support assembly 150. An installation groove 111 is formed on the base 110, the inner support assembly 150 is received in the installation groove 111, and the outer housing 120 is covered on the inner support assembly 150 and the base 110.

[0037] The bottom of the installation groove 111 is a hollow structure, and a resonance cavity 121 is formed between the outer housing 120 and the base 110 (as Figure 3 shown), the sound pickup 140 is arranged in the resonance cavity 121 through the fixing member 130, the fixing member 130 is connected to the outer housing 120, and the sound pickup 140 is located above the inner support assembly 150.

[0038] Among them, as Figure 4As shown in the figure, the inner support assembly 150 includes a diaphragm 151, an inner threaded member 152 of the membrane sleeve, and an outer threaded member 153 of the membrane sleeve. The diaphragm 151 is clamped between the inner threaded member 152 of the membrane sleeve and the outer threaded member 153 of the membrane sleeve. Preferably, an internal thread is provided inside the inner threaded member 152 of the membrane sleeve, and an external thread is provided on the outer side of the outer threaded member 153 of the membrane sleeve. The internal thread and the external thread are adapted and connected. In this way, rotating the outer threaded member 153 of the membrane sleeve can cause it to rise or fall relative to the inner threaded member 152 of the membrane sleeve, thereby changing the clamping degree of the two on the diaphragm 151 to achieve the purpose of adjusting the tone.

[0039] Preferably, as Figure 2 and Figure 4 shown in the figure, an elastic buckle 154 is provided on the inner threaded member 152 of the membrane sleeve, and a buckle seat (not shown in the figure) cooperating with the elastic buckle 154 is provided in the installation groove 111. During installation, the elastic buckle 154 of the inner threaded member 152 of the membrane sleeve can be inserted into the buckle seat to achieve snap connection, thereby fixedly installing the inner threaded member 152 of the membrane sleeve into the installation groove 111. After installation, the inner threaded member 152 of the membrane sleeve cannot move or rotate. Therefore, when adjusting the clamping degree of the diaphragm 151, the user only needs to rotate the outer threaded member 153 of the membrane sleeve to cause the outer threaded member 153 of the membrane sleeve to rise or fall within the inner threaded member 152 of the membrane sleeve.

[0040] The working principle of the sound pickup device 100 of the present utility model is as follows:

[0041] Below the installation groove 111 is the air duct of the electronic kazoo. The breath emitted by the user's humming enters the air duct and causes the diaphragm 151 to resonate. The sound generated by the vibration of the diaphragm 151 will fill the entire resonance cavity 121, and then be collected by the sound pickup 140 in the resonance cavity 121, thereby achieving the purpose of sound pickup.

[0042] It should be noted that the traditional kazoo does not have an additional resonance cavity 121. In the technical solution of the present utility model, the setting of the resonance cavity 121 can make the sound generated by the vibration of the diaphragm 151 clearer and more surround stereo, which helps to improve the sound pickup effect and avoid the interference of other environmental noises on the sound pickup 140.

[0043] The Chinese utility model patent with the publication number of "CN220672204U" and the name of "A new type of sound pickup component for kazoo" in the prior art discloses a sound pickup component for an electronic kazoo, which also has a resonance cavity for installing a sound pickup microphone. However, in the present utility model, the resonance cavity 121 and the air duct are independent of each other, and the resonance cavity 121 and the air duct are separated by the diaphragm 151. Such a setting can make the resonance cavity 121 form a relatively independent and closed space, thereby improving the accuracy of the sound pickup 140 in recording the vibration sound of the diaphragm 151 and avoiding recording the user's breathing sound or other noisy sound sources.

[0044] It can be seen that the sound pickup device 100 of the present utility model has the following advantages compared with the prior art:

[0045] Compared with the external sound pickup components of the prior art, the sound pickup device 100 of the present utility model is provided with a housing 120, and the housing 120 completely wraps the sound pickup 140 and the inner support assembly 150. In this way, the interference of external sounds to the sound pickup 140 and the diaphragm 151 can be greatly reduced, and the installation process is relatively simple. It only needs to sequentially stack the inner support assembly 150, the sound pickup 140 and the fixing member 130, and finally cover the housing 120 on the base 110;

[0046] Compared with the built-in sound pickup components of the prior art (such as the utility model patent with the publication number of "CN220672204U" mentioned above), the sound pickup device 100 of the present utility model is provided with a relatively independent resonance cavity 121. In this way, during use, the breathing sounds and humid gases of the user can be isolated, thereby improving the sound pickup effect, avoiding the recording of noisy sound sources, and also preventing the sound pickup 140 from being affected by water vapor.

[0047] In this embodiment, as Figure 2 shown, the base 110 is provided with a convex column 112, the housing 120 is provided with a through hole 122 and a screw 123, and the screw 123 passes through the through hole 122 and is connected to the convex column 112, so as to realize the installation of the housing 120 on the base 110.

[0048] The present utility model also provides an integrated electronic kazoo 10, as Figure 5 、 Figure 6 and Figure 7 shown, which includes the above-mentioned sound pickup device 100, and further includes: a main body 200, a mouthpiece 300 and an electronic sound generating device 400.

[0049] Among them, the main body 200 includes a main body upper shell 210 and a main body lower shell 220, and the base 110 of the sound pickup device 100 is arranged on the main body upper shell 210. A wind channel 201 (as Figure 7 shown) is formed between the main body upper shell 210 and the main body lower shell 220, and the wind channel 201 is located below the sound pickup device 100.

[0050] The mouthpiece 300 is arranged at the end of the main body 200, and a blowing port 310 communicating with the wind channel 201 is opened on the mouthpiece 300 (as Figure 5 shown). Preferably, the mouthpiece 300 is connected to the main body 200 through a snap structure, and such a setting is beneficial for the user to conveniently replace the mouthpiece 300.

[0051] An accommodation chamber 202 (as Figure 7 shown) is also formed between the main body upper shell 210 and the main body lower shell 220, and the electronic sound generating device 400 is arranged in the accommodation chamber 202. AsFigure 7 and Figure 8 As shown in Figure 8 , the electronic sound - generating device 400 includes: a PCB board 410, a battery 420, and a speaker 430. Both the battery 420 and the speaker 430 are electrically connected to the PCB board 410, and the PCB board 410 is electrically connected to the microphone 140 of the sound - pickup device 100.

[0052] The working principle of the integrated electronic kazoo 10 of the present utility model is as follows. Refer to Figure 7 and Figure 8 :

[0053] During performance, the user's mouth faces the air - blowing port 310 of the mouthpiece 300 and emits humming sounds according to the rhythm. The sound travels in the air duct 201. The sound wave formed by the sound is transmitted through the air duct to the diaphragm 151 of the sound - pickup device 100. The diaphragm 151 vibrates to emit sounds with different amplitudes. Subsequently, the microphone 140 collects the sound emitted by the diaphragm 151, converts it into an electrical signal, and sends it to the PCB board 410. Then, after being processed by the PCB board 410, it is emitted through the speaker 430. The speaker 430 can increase the loudness of the sound playback, making the sound propagation range wider.

[0054] In addition, the PCB board 410 can be provided with a wireless communication module, and then connected to communication devices such as mobile phones through Bluetooth or other means, and play the music in the mobile phone through the speaker 430, so as to achieve an accompaniment effect and enhance the music effect. Preferably, an earphone jack (not shown in the figure) electrically connected to the PCB board 410 can also be provided on the main body 200. The user can connect the integrated electronic kazoo 10 to other power - amplifier devices through this earphone jack to achieve the music external - playing effect.

[0055] Compared with the prior art, the integrated electronic kazoo 10 of the present utility model integrates the electronic sound - generating device 400 in the accommodation chamber 202. And, by using the height difference to stagger the speaker 430 and the air duct 201 from each other, high - degree integration is achieved, making full use of the space inside the main body 200, thereby reducing the overall volume of the electronic kazoo and achieving convenient carrying.

[0056] Preferably, a switch button 230, a volume - adjustment button 240, and a charging interface 250 are provided on the side wall of the main body 200, and the switch button 230, the volume - adjustment button 240, and the charging interface 250 are all electrically connected to the PCB board 410. During performance, the user can select whether to enable the speaker 430 through the switch button 230 and change the power - amplification level of the speaker 430 through the volume - adjustment button 240, thereby changing the loudness of the sound playback.

[0057] Preferably, as Figure 6 and Figure 9As shown, honeycomb through-holes 211 are formed in the main body upper shell 210, and the speaker 430 is disposed inside the main body 200 and faces the honeycomb through-holes 211.

[0058] Furthermore, in actual use, it is found that the exhaled gas of the user often contains saliva. To avoid the accumulation of saliva inside the main body 200, in this embodiment, as Figure 7 and Figure 9 shown, a drain port 221 is formed in the main body lower shell 220, and the drain port 221 is communicated with the air duct 201. During the playing process, the saliva will be discharged from the drain port 221 along with the air flow, thus avoiding accumulation.

[0059] Preferably, as Figure 7 and Figure 9 shown, a separation plate 222 is provided between the main body upper shell 210 and the main body lower shell 220. The separation plate 222 is located above the drain port 221, and the separation plate 222 is used to isolate the speaker 430 from the air duct 201. Since the exhaled gas of the user is relatively humid, the separation plate 222 is provided to separate the speaker 430 from the air duct 201. In this way, the speaker 430 will not be affected by the humid gas. At the same time, the water vapor in the gas will condense into water droplets and drip near the drain port 221, and then be discharged from the drain port 221 along with the air flow.

[0060] In one of the embodiments, as Figure 8 and Figure 9 shown, a light bar 212 is further provided on the surface of the main body upper shell 210, and the light bar 212 is electrically connected to the PCB board 410. During the playing, the light bar 212 can flash or change color according to the intensity and rhythm of the music, thereby improving the visual effect.

[0061] In summary, a sound pickup device 100 and an integrated electronic kazoo 10 of the present invention can improve the accuracy of the sound recorded by the sound pickup 140 and avoid recording other noisy sound sources; at the same time, reduce the overall volume and achieve convenient carrying.

[0062] The above embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
