Description

Technical Field

[0001] The invention relates to audio, in particular to a personal wearable audio backpack with dynamic body sensation in a disco, karaoke or music hall. Background Art

[0002] Music is transmitted to people's ears and bodies through sound waves, so that people can feel the beautiful melody and shock of music. Soft music can achieve the ideal auditory effect through auditory perception, while strong music can not achieve the ideal effect only through auditory perception. It is more necessary to combine the actual feeling of body vibration and pressure to achieve the ideal effect. Sound is transmitted through air, and air is a substance with a very high compression ratio. It takes several times the kinetic energy to make the body feel pressure through air as a medium. Therefore, several or dozens of large-sized subwoofers are placed in concerts, theaters, concert halls, KTVs, and bars to create a sound pressure area so that people in it can feel the vibration and pressure from the body.

[0003] However, concerts, theaters, music halls and other places are all specific business places, which make it impossible for people to enjoy this powerful dynamic music anytime and anywhere. In the related art, various outdoor speakers are disclosed. In order to create a stronger sound effect, these speakers usually use high-power amplifiers to amplify the signal. Therefore, they are large in size and not easy to carry. At the same time, the vibration output of these devices is also directly transmitted into the air, and in an open environment, the body vibration cannot be felt. Summary of the invention

[0031] The personal wearable karaoke music hall dynamic somatosensory audio backpack according to the embodiment of the present invention is described in detail below with reference to the accompanying drawings.

[0032] Reference Figures 1 to 9 As shown, the personal wearable karaoke music hall dynamic body-sensing audio backpack provided according to an embodiment of the present invention includes a wearable bag body 10a (10b) and an audio host 20.

[0033] The wearable bag 10a (10b) can be various types of bags, such as backpacks, waist bags, etc., and the size of the wearable bag 10a (10b) can be set as needed. For example, it can be a commuter bag with a large storage space that can accommodate some personal work or daily necessities, or it can be a sports bag with a small storage space that can only accommodate some necessities required for sports. Exemplarily, the sports bag can have a shoulder strap 102b and a waist belt 101b, and the shoulder strap 102b is configured as a detachable structure. When used outdoors, the shoulder strap 102b and the waist belt 101b can be used for wearing at the same time. When used in scenes such as indoors, the shoulder strap 102b can be removed and the waist belt 101b can be directly used for wearing, which is flexible and convenient to use.

[0034] The wearable bag body 10a (10b) is provided with an audio storage cavity P10, and the audio storage cavity P10 is used to install and fix the audio host 20, so as to ensure that the audio host 20 can be stably loaded on the wearable bag body 10a (10b). The wearable bag body 10a (10b) has a somatosensory surface S10 that contacts the human body when worn, and the somatosensory surface S10 includes a somatosensory area S101, that is, when the wearable bag body 10a (10b) is worn on the user, the somatosensory surface S10 can contact the human body, for example, when the wearable bag body 10a (10b) is a backpack, when the backpack is carried on the back of the user, the somatosensory area S101 can contact the back of the user. The audio host 20 is accommodated in the audio storage cavity P10, and the audio host 20 includes a casing and a vibration speaker 202. The casing is adapted to the shape and size of the storage cavity to ensure that the audio host 20 is firmly installed and avoids shaking when it is installed in the audio storage cavity P10. The vibration speaker 202 is arranged on the casing and contacts the somatosensory area S101, so as to transmit the vibration effect to the human body through the somatosensory area S101 during work. Since the vibration speaker 202 is located in the somatosensory area S101, and during use, the somatosensory area S101 contacts the user, therefore, the vibration of the vibration speaker 202 can be directly transmitted to the user through the somatosensory area S101, and the user can directly feel the vibration effect with the music. The somatosensory area S101 is the area corresponding to the vibration speaker 202, therefore, the somatosensory area S101 is the vibration center of the somatosensory surface S10.

[0035] In actual use, the user wears the wearable bag body 10a (10b) on himself. Taking a backpack as an example, the backpack is worn on the back of the user, and the somatosensory surface S10 is in contact with the back of the user. When music is playing, the vibration speaker 202 will generate corresponding vibrations according to the rhythm and intensity of the music. These vibrations are not dissipated into the air, but are directly transmitted to the user's body through the close contact between the housing and the somatosensory area S101. This direct vibration conduction method allows even low-power vibration output to bring significant somatosensory effects. At the same time, since a stable mechanical coupling is established between the vibration source (vibration speaker 202) and the human body, the transmission efficiency of the vibration energy is greatly improved, avoiding the loss of vibration energy when it is transmitted through the air in traditional audio equipment.

[0036] Through this structural design, the audio backpack of this embodiment successfully miniaturizes the shocking music effect that can only be experienced in large venues into a portable personal device. Users can enjoy a complete music experience with both beautiful melodies and strong vibrations anytime and anywhere. Especially in scenes such as outdoor and travel, this portable design shows unique advantages.

[0037] It should be noted that the related art discloses some audio bags, which are only for the convenience of carrying audio and combine audio with backpacks, without considering the purpose of vibration. The speakers are usually located on the side away from the human body, and the sound is directly diffused into the surrounding air, which cannot produce human body vibration.

[0038] According to the personal wearable karaoke music hall dynamic somatosensory audio backpack provided by the embodiment of the present invention, the vibration speaker 202 is directly in contact with the somatosensory area S101 of the wearable bag body 10a (10b), and the somatosensory area S101 is closely fitted to the human body, thereby establishing a direct transmission path from the vibration source to the human body, achieving efficient transmission of vibration energy, so that even a small portable device can bring a shocking somatosensory effect similar to that of a large venue. This not only solves the problem that traditional audio equipment is bulky and inconvenient to carry, but more importantly, it breaks through the limitation that an ideal vibration feeling cannot be obtained in an open outdoor environment. Through this portable design, users can enjoy the dual feelings of hearing and vibration brought by powerful music anytime and anywhere, truly realizing a personalized immersive music experience.

[0039] Reference Figure 1 and Figure 2 As shown, in one embodiment of the present invention, the somatosensory surface S10 also includes a heat dissipation area S102, and the heat dissipation area S102 is provided with mesh holes. For example, the heat dissipation area S102 can be made of mesh cloth, and the mesh holes on the mesh cloth are conducive to improving the heat dissipation and ventilation effect. The audio host 20 also includes a heat dissipation fan 203, and the heat dissipation fan 203 is arranged in the housing. The housing has a heat dissipation surface S20 opposite to the heat dissipation area S102, and the heat dissipation surface S20 is provided with an air outlet H20a and a heat dissipation dispersion structure.

[0040] The air outlet H20a is connected to the air outlet side of the heat dissipation fan 203, ensuring that the airflow generated by the heat dissipation fan 203 can be smoothly discharged from the housing through the air outlet H20a. The heat dissipation dispersion structure is configured to disperse the hot air blown out of the air outlet H20a to the heat dissipation surface S20, so as to blow the hot air out from the heat dissipation area S102 through the heat dissipation surface S20.

[0041] The main function of the heat dissipation structure is to reasonably disperse the hot air blown out from the air outlet H20a. This dispersion design prevents the hot air from being concentrated in the area corresponding to the air outlet H20a, but can be evenly distributed on the entire heat dissipation surface S20. After the hot air passes through the heat dissipation dispersion structure, it will be evenly blown out from the mesh of the heat dissipation area S102 of the somatosensory surface S10 through the heat dissipation surface S20.

[0042] In this embodiment, the mesh design of the heat dissipation area S102 of the somatosensory surface S10, combined with the heat dissipation fan 203 and the heat dissipation dispersion structure in the housing, achieves efficient and uniform heat dissipation effect. It can not only effectively reduce the operating temperature of the equipment and improve the reliability and service life of the audio host 20, but also avoid local overheating and discomfort to the user through uniform heat dispersion, thereby improving the user experience.

[0043] It is understandable that the heat dissipation dispersion structure may be in the form of guide plates, heat dissipation fins or grilles, etc. These structures can not only guide the airflow direction, but also increase the heat exchange area, thereby further improving the heat dissipation efficiency.

[0044] Preferably, the vibration speaker 202 is located at the center of the heat dissipation surface S20 on the casing, and correspondingly, the heat dissipation area S102 is located around the body sensing area S101.

[0045] Reference Figure 4 and Figure 6 As shown, in one embodiment of the present invention, the heat dissipation structure includes a plurality of shunt grooves H20b arranged at intervals, and the shunt grooves H20b extend along a predetermined direction on the heat dissipation surface S20. For example, the shunt grooves H20b are arranged on the heat dissipation surface S20 at a predetermined interval to form a regular parallel structure or a concentric circle structure.

[0046] In actual application, when the cooling fan 203 is working, hot air is first ejected from the air outlet H20a, and then immediately dispersed and guided by the orderly arranged diversion grooves H20b to form multiple uniform airflows, thereby allowing the entire cooling surface S20 to participate in the cooling process.

[0047] In this embodiment, a plurality of shunt grooves H20b arranged at intervals are provided to achieve uniform dispersion and orderly conduction of heat. This structural design not only improves the heat dissipation efficiency, but also reduces the airflow velocity, reduces airflow noise, achieves low-noise operation, and ensures structural strength. In other words, the regular arrangement and directional extension of the shunt grooves H20b enable the entire heat dissipation surface S20 to more fully conduct heat, thereby ensuring that the device maintains a stable operating temperature and a good user experience during long-term use.

[0048] Reference Figure 4 and Figure 6 As shown, in one embodiment of the present invention, the heat dissipation surface S20 is provided with a plurality of partition bars 2013 , the plurality of partition bars 2013 are arranged at intervals, and the diversion groove H20b is defined between two adjacent partition bars 2013 .

[0049] In this embodiment, spacers 2013 are arranged at intervals on the heat dissipation surface S20, and the spacers 2013 are used to separate and form diverter grooves H20b. This design of using the spacers 2013 to form the diverter grooves H20b, on the one hand, maintains the airflow dispersion and guiding function of the diverter grooves H20b, and on the other hand, the spacers 2013 significantly increase the heat dissipation area of ​​the entire heat dissipation surface S20, further improving the heat dissipation effect. On another hand, the spacers 2013 can also enhance the structural strength of the casing.

[0050] Preferably, each of the partition bars 2013 is provided with a plurality of openings H20c, and the plurality of openings H20c are sequentially arranged at intervals along the extension direction of the partition bars 2013 to connect the adjacent diverter slots H20b. When the hot air is ejected from the air outlet H20a of the heat dissipation fan 203, it will first flow along the main direction of the diverter slots H20b, and at the same time diffuse laterally through the openings H20c on the partition bars 2013. This three-dimensional airflow diffusion method significantly improves the uniformity of heat dispersion. The presence of the openings H20c can also balance the pressure difference between the diverter slots H20b, avoiding the occurrence of local airflow dead zones or excessive concentration.

[0051] It is understandable that the housing can be configured in various shapes. For example, the housing is rectangular, and the partition bar 2013 extends along the length direction and / or width direction of the housing. Or the housing is circular, and the partition bar 2013 extends along the circumference of the housing. In this way, the partition bars 2013 arranged in the above manner can form parallel or concentric shunt grooves H20b, thereby achieving regular dispersed heat conduction.

[0052] Reference Figure 4 As shown, in one embodiment of the present invention, there are two cooling fans 203 , and the two cooling fans 203 are respectively arranged on both sides of the vibration speaker 202 .

[0053] There are two air outlets H20a, and the two air outlets H20a correspond to the two cooling fans 203 one by one. Each air outlet H20a is communicated with the air outlet side of the corresponding cooling fan 203.

[0054] In actual operation, the two cooling fans 203 can work synchronously to form a synergistic cooling effect. Since the cooling fans 203 are located on both sides of the vibration speaker 202, this layout can effectively cover the heat distribution area generated by the electrical components inside the housing when they are working. When the heat is discharged through the two independent air outlets H20a, the hot air flow will be further guided and dispersed by the diverter slot H20b structure on the heat dissipation surface S20, and finally discharged evenly through the mesh of the heat dissipation area S102.

[0055] This design of symmetrically arranged dual fans achieves comprehensive heat dissipation coverage inside the casing and improves the overall heat dissipation efficiency. In addition, it helps to maintain the balance of temperature distribution inside the device and avoids local overheating. Furthermore, the dual-fan design increases the reliability of the entire audio host 20. Even if a single cooling fan 203 fails, the other cooling fan 203 can still maintain basic heat dissipation functions, thereby improving the reliability and safety of the audio host 20.

[0056] Reference Figures 3 to 6 As shown, in one embodiment of the present invention, a through hole H20d is provided on the housing, and a vibration seat 2012 in contact with the body sensing area S101 is provided in the through hole H20d.

[0057] The four sides of the vibration seat 2012 are connected to the inner wall of the through hole H20d through elastic strips 2012a. There are multiple elastic strips 2012a, and the multiple elastic strips 2012a are spaced apart in the circumferential direction of the vibration seat 2012. The vibration speaker 202 is located in the housing and fixed on the vibration seat 2012.

[0058] In this embodiment, a through hole H20d is provided on the housing, a vibration seat 2012 is provided in the through hole H20d, and a plurality of elastic strips 2012a are provided at intervals in the circumferential direction of the vibration seat 2012, and these elastic strips 2012a flexibly connect the vibration seat 2012 to the inner wall of the through hole H20d. This arrangement of the elastic strips 2012a at intervals ensures that the vibration seat 2012 can obtain a balanced supporting force in all directions while maintaining sufficient freedom of movement.

[0059] The vibration speaker 202 is fixedly mounted on the vibration base 2012. The vibration generated by the vibration speaker 202 is first transmitted to the vibration base 2012, and then transmitted to the body sensing area S101 through the vibration base 2012. The existence of the elastic strip 2012a plays a key regulatory role in the vibration transmission process. First, the elastic strip 2012a allows the vibration base 2012 to vibrate freely within a certain range, ensuring the effective transmission of vibration energy and enhancing the vibration body sense; secondly, the elastic strip 2012a can absorb and buffer some unnecessary vibrations to avoid the generation of messy vibrations; thirdly, the uniform distribution of multiple elastic strips 2012a ensures the directionality and uniformity of vibration transmission.

[0060] Through the design of the elastically supported vibration seat 2012, precise control and directional transmission of vibration are achieved while ensuring effective transmission of vibration; the setting of the elastic strip 2012a not only protects the equipment from excessive vibration, but also improves the comfort of the vibration experience; the overall structure is simple and reliable, easy to assemble and maintain, and has a good service life and stability.

[0061] Reference Figure 4 As shown, in one embodiment of the present invention, the elastic strip 2012a is formed into an arc shape concentric with the through hole H20d, one end of the elastic strip 2012a is bent outward and connected to the inner wall of the through hole H20d, and the other end of the elastic strip 2012a is bent inward and connected to the outer wall of the vibration seat 2012.

[0062] In this embodiment, the elastic strip 2012a is designed to be a concentric arc shape. The arc-shaped elastic strip 2012a allows a smaller distance between the vibration seat 2012 and the hole wall of the through hole H20d. Under this premise, the elastic strip 2012a has a sufficient length, so that the vibration seat 2012 has sufficient vibration freedom. That is, while ensuring the compactness of the overall structure, the vibration freedom of the vibration seat 2012 is also guaranteed. When the vibration base 2012 is subjected to the vibration force of the vibration speaker 202, the arc-shaped elastic strip 2012a can distribute the stress more evenly over the entire structure to avoid stress concentration. At the same time, the arc-shaped elastic strip 2012a provides sufficient deformation space, so that the elastic strip 2012a can maintain good elastic response characteristics under different vibration frequencies and amplitudes. This design not only ensures the effect of vibration transmission, but also makes the vibration transmission process smoother and more controllable.

[0063] Reference Figure 3 and Figure 5 , Figure 6 As shown, in one embodiment of the present invention, the housing includes a back housing 201a and a front housing 201b, the back housing 201a is connected to the front housing 201b, and the heat dissipation surface S20 is located on the back housing 201a.

[0064] The cooling fan 203 is a side air outlet structure, and an air guide cover 2011 is provided on the back shell 201a. The air guide cover 2011 connects the air outlet side of the cooling fan 203 with the air outlet H20a, and the air guide cover 2011 has an inclined guide surface S21, and the inclined guide surface S21 extends obliquely between the air outlet side of the cooling fan 203 and the air outlet H20a.

[0065] The heat dissipation fan 203 in this embodiment adopts a side air outlet structure, which not only makes the structure more compact, but also takes into account the fact that the wind is more fully guided to each diversion slot H20b of the heat dissipation surface S20. In order to better guide the airflow, an air guide cover 2011 is provided on the back shell 201a. The function of the air guide cover 2011 is to establish a closed airflow channel, connecting the air outlet side of the heat dissipation fan 203 with the air outlet H20a.

[0066] More importantly, the air guide cover 2011 has an inclined guide surface S21, which forms an inclined extending guide area between the air outlet side of the cooling fan 203 and the air outlet H20a. When the airflow passes through the guide area, the direction of the airflow can be changed, so that the airflow blown out laterally by the cooling fan 203 is inclined to flow toward the heat dissipation surface S20. Compared with the vertical air outlet structure, it can effectively reduce the turbulence of the airflow during the turning process, reduce the airflow resistance and energy loss, and the airflow can flow more smoothly from the air outlet side of the fan to the air outlet H20a, and then flow from the air outlet H20a into each diversion groove H20b, thereby significantly improving the efficiency of the airflow flowing into each diversion groove H20b, and the airflow dispersion is more sufficient.

[0067] In actual operation, when the heat dissipation fan 203 is working, the hot air is first blown out from the side of the fan, and then smoothly turns along the inclined guide surface S21 under the guidance of the wind guide cover 2011. In this process, the inclined guide surface S21 not only changes the direction of the airflow, but also plays a role in pre-dispersing the airflow. When the airflow is finally discharged from the air outlet H20a, a relatively uniform airflow distribution has been formed, providing a good airflow foundation for the subsequent heat dissipation dispersion structure.

[0068] In other words, through the combination of the cooling fan 203 with the side air outlet structure and the air guide cover 2011, efficient guidance and smooth turning of the airflow are achieved, effectively reducing airflow loss and noise, and improving the overall heat dissipation efficiency. The gradual design of the inclined guide surface S21 not only optimizes the airflow path, but also provides a good airflow foundation for subsequent heat dissipation, making the entire heat dissipation process more coordinated and efficient.

[0069] Reference Figure 3 and Figure 5 As shown, in one embodiment of the present invention, the housing is provided with an air inlet H20e opposite to the cooling fan 203, and the wearable bag body 10a (10b) is provided with an air inlet hole H10a opposite to the air inlet H20e.

[0070] By setting corresponding air inlets H20e and air inlet holes H10a on the casing and the wearable bag body 10a (10b), a channel connected to the external environment is formed, through which air can be directly inhaled from the external environment, ensuring that the cooling fan 203 obtains a sufficient and stable air intake source, thereby not only improving the heat dissipation efficiency, but also improving the reliability of the device in the actual use environment.

[0071] Reference Figure 5As shown, in one embodiment of the present invention, the audio body further includes an amplifier board 204 and a battery 205 disposed in the housing, the housing is provided with a heat dissipation port H20f opposite to the amplifier board 204 and the battery 205, and the wearable package 10a (10b) is provided with a heat dissipation hole H10b opposite to the heat dissipation port H20f. Preferably, the air inlet hole H10a is located at the bottom of the wearable package 10a (10b), and the heat dissipation hole H10b is located on both sides of the wearable package 10a (10b).

[0072] As components of the audio host 20, the power amplifier board 204 and the battery 205 generate considerable heat during operation. Therefore, a heat dissipation port H20f corresponding to the power amplifier board 204 and the battery 205 is provided on the housing, and at the same time, a heat dissipation hole H10b is provided at a corresponding position on the wearable bag 10a (10b), forming a heat dissipation channel with the heat dissipation port H20f on the housing, which is conducive to the heat dissipation of the power amplifier board 204 and the battery 205.

[0073] In addition, the air inlet H10a is arranged at the bottom of the wearable bag body 10a (10b), while the heat dissipation holes H10b are distributed on both sides of the wearable bag body 10a (10b). This layout design makes full use of the natural convection principle of hot air rising. When the device is working, the cooler air enters from the air inlet H10a at the bottom, is heated after passing through the internal electronic components, and the hot air then naturally rises and is discharged from the heat dissipation holes H10b on both sides.

[0074] Through the above-mentioned heat dissipation design, not only the operating temperature of the internal components can be effectively reduced, but also the entire audio host 20 can be ensured to maintain a stable working state during long-term use, providing users with a stable and long-lasting use experience.

[0075] In one embodiment of the present invention, the power amplifier board 204 has a speaker power amplifier circuit, a wired headset 31 power amplifier circuit and a wireless audio transmission control circuit. The speaker power amplifier circuit is used to amplify the audio signal and output it through the vibration speaker 202. The wired headset 31 power amplifier circuit is used to amplify the audio signal and output it to the wired headset 31 through the headset interface H20g. The wireless audio transmission control circuit is used to amplify the audio signal and send it to the wireless headset 30 wirelessly.

[0076] That is to say, the power amplifier board 204 has a variety of audio output modes, which fully meets the diverse needs of users in different scenarios. First, the power amplifier board 204 is equipped with a speaker power amplifier circuit, which amplifies the audio signal and then transmits it to the vibration speaker 202 for output, so as to achieve audio external playback. Secondly, the power amplifier board 204 is equipped with a wired headset 31 power amplifier circuit. The wired headset 31 power amplifier circuit is connected to the standard headphone interface H20g for driving the wired headset 31. The headphone interface H20g is provided on the housing, and is used to connect the wired headset 31 to the headphone interface H20g, so as to achieve audio playback through the wired headset 31. Thirdly, the power amplifier board 204 also integrates a wireless audio transmission control circuit. The wireless audio transmission control circuit can digitally process and encode the audio signal, and then transmit it to the paired wireless headset 30 by wireless mode, so that the audio playback of the wireless headset 30 can be achieved.

[0077] This embodiment realizes the diversification of audio output modes, which can not only meet the needs of personal private listening, but also provide a shocking music experience. For example, when the user needs to enjoy a private music experience, the wired or wireless headset 30 mode can be selected; when a shocking music experience is needed, the speaker amplifier circuit can be enabled to experience the immersive effect brought by the vibration speaker 202.

[0078] Exemplarily, the housing is also provided with a charging interface H20h for charging the audio host 20, and a charging interface H20i for powering an external device. In this way, the battery 205 can be charged using the charging interface H20h, and the external device can be charged using the charging interface H20i, that is, the audio host 20 can be used as a mobile power supply.
