Description

Technical Field

[0001] This utility model relates to the field of sofa accessories technology, and in particular to a manual audio control device and furniture having the same. Background Technology

[0002] In modern home life, furniture has gone far beyond providing basic functions; its comfort and functionality have increasingly become core concerns for consumers. As an important carrier for rest, relaxation, socializing, and entertainment within the home, furniture design concepts are constantly evolving. Rapid technological advancements are profoundly impacting the home furnishing sector, and consumers' expectations for furniture are continuously rising. They not only demand that furniture meet basic needs such as sitting, lying down, and storage, but also expect it to integrate intelligent and entertainment functions to significantly enhance the convenience and experience of daily life. This trend of integrating technology is reshaping the definition and value of modern furniture.

[0003] In terms of entertainment, audio systems are an indispensable part. Integrating audio systems into furniture, allowing users to enjoy an immersive audio experience while resting or entertaining, has become a new development trend. However, among many furniture categories, sofas and chairs, as the core rest and entertainment space where family members spend the most time and use the most, require particularly innovative functionality. Existing audio devices integrated into sofas and chairs have shortcomings in design and performance.

[0004] In the design of the installation position and angle of the speakers, many devices do not fully consider the principles of ergonomics. For example, in some devices, the axis of the speaker is installed perpendicular to the mask, and the sound travels directly forward. However, when users use sofas or chairs, their heads are usually in a certain tilted position, which makes it impossible for the sound to travel effectively to the ears. This results in low sound propagation efficiency, and users need to turn up the volume to get a better listening experience. This not only increases energy consumption but may also affect the sound quality. Utility Model Content

[0005] The purpose of this utility model is to disclose a novel hand-controlled device that improves the sound propagation efficiency and sound source perception effect of the audio system by optimizing the structure of the speaker and the mask, and by reasonably setting the control unit.

[0006] To achieve the above objectives, this utility model discloses a manual audio control device, comprising: a housing, the housing including a base portion having a receiving cavity and a face mask fastened to the base portion, the housing being embedded in furniture, and the face mask protruding from the surface of the furniture; an audio module disposed within the receiving cavity, the audio module including a speaker mounted toward the face mask, the speaker being obliquely disposed between the speaker and the face mask; and a control unit disposed on the face mask.

[0007] By adopting the above solution and tilting the speaker and mask, sound can be transmitted to the ear more directly and effectively when the user is sitting or lying on furniture such as sofas or chairs to rest or entertain themselves. This improves the sound transmission efficiency, and the user can obtain a better listening effect without having to turn up the volume. This reduces energy consumption and ensures sound quality. Due to the tilted setting, the speaker can be closer to the mask and the center point is relatively low, achieving maximum volume and avoiding the "muffled" sound caused by the sound not being able to escape.

[0008] Furthermore, the mask surface has a first direction and a second direction that are perpendicular to each other, the horn is flipped and tilted 10°-60° along the first direction of the mask, and / or the horn is flipped and tilted 10°-60° along the second direction of the mask.

[0009] By adopting the above solution, different users have different postures and head tilt angles on the furniture. The tilt angle range of 10°-60° can cover the usage scenarios of most users. When the space of the furniture is relatively compact, a smaller tilt angle such as 10°-20° can ensure the normal operation of the speaker without taking up too much space. When the space is relatively spacious, a larger tilt angle such as 30°-60° can further optimize the sound propagation effect.

[0010] Furthermore, the horn is tilted 20° in a first direction along the mask, and / or the horn is tilted 20° in a second direction along the mask.

[0011] By adopting the above design, the 20° tilt angle, ergonomically designed, effectively directs the sound emitted by the speaker towards the user's ear. When a user is reclining in a relaxed position on a sofa or other furniture, with their head tilted back at a certain angle, the 20° tilt of the speaker allows the sound propagation direction to better match the user's ear position, reducing sound scattering and attenuation during propagation. This ensures that the sound enters the ear directly and clearly, improving sound propagation efficiency. The 20° tilt angle also allows the sound to propagate at a more suitable angle, reducing the number of reflections within the internal space, presenting sound details more clearly, and reducing noise interference.

[0012] Furthermore, the mask includes a sound-emitting area and a control area spaced apart, the sound-emitting area corresponding to the audio module and the control area corresponding to the control unit.

[0013] By adopting the above scheme, the sound output area is set up to correspond to the speaker module, and the control area is set up to correspond to the control unit. This clear partitioning allows users to quickly distinguish between different functional areas. When operating the control unit, it is less likely to accidentally touch the sound output area, thus avoiding problems such as audio system malfunctions or sound interruptions that may be caused by accidental touches.

[0014] Furthermore, the sound-emitting area includes a plurality of sound-emitting holes, which are strip-shaped and radially distributed along the center of the sound-emitting area.

[0015] By adopting the above solution, sound can propagate at a wider angle. Compared to a sound outlet design concentrated in one direction or a small area, this layout allows sound to cover a larger space. The radial distribution also reduces blind spots in sound propagation. Sound is emitted from strip-shaped sound outlets in different directions, complementing each other and making the sound distribution more even throughout the space. Whether near furniture or at a distance, users can enjoy a better listening experience. At the same time, the more rational layout can disperse stress, reducing the risk of mask damage due to excessive localized stress.

[0016] Furthermore, the control unit includes a knob unit and a button unit, with the button unit located between the knob unit and the sound output area.

[0017] By adopting the above solution, users can quickly distinguish different functional areas during operation. This allows for rapid location of the button units, avoiding misoperations caused by confusion of functional areas and improving operational efficiency and accuracy.

[0018] Furthermore, the mask is also equipped with an LED strip, which is electrically connected to the control unit.

[0019] By adopting the above solution, the color, brightness, and flashing frequency of the light strip can be freely adjusted via the control unit, allowing users to experience the charm of technology. At night, the light strip can serve as an auxiliary lighting tool. It can also be used to indicate the operating status of equipment or provide safety reminders.

[0020] Furthermore, the outer shell is provided with a first snap-fit ​​portion, and the edge of the face mask is provided with a mounting plate facing the outer shell, and the surface of the mounting plate is provided with a second snap-fit ​​portion that snaps into the first snap-fit ​​portion.

[0021] By adopting the above solution, the cooperation between the first and second snap-fit ​​parts can achieve precise positioning. During installation, the interlocking between the snap-fit ​​parts ensures that the mask is accurately installed in the predetermined position on the outer shell, avoiding problems such as mask skewing and uneven gaps caused by installation deviations.

[0022] Furthermore, between the first snap-fit ​​portion and the second snap-fit ​​portion, one is a snap-fit ​​protrusion, and the other is a snap-fit ​​groove that snaps into the snap-fit ​​protrusion.

[0023] By adopting the above-described solution, the engagement of the snap-fit ​​protrusion and the snap-fit ​​groove makes the installation process extremely simple. The operator only needs to align the outer shell or face mask with the snap-fit ​​protrusion with the corresponding component with the snap-fit ​​groove, and then apply a certain amount of pressure to allow the snap-fit ​​protrusion to slide smoothly into the snap-fit ​​groove, thus completing the installation. No complex tools such as screwdrivers and wrenches are required, greatly saving installation time and labor costs. The engagement between the snap-fit ​​protrusion and the snap-fit ​​groove creates a strong mechanical interlocking force, capable of withstanding a certain amount of tensile and shearing forces. This connection method ensures that the outer shell and face mask maintain a stable connection during long-term use, preventing them from easily loosening or falling off.

[0024] A piece of furniture includes a furniture body and a speaker hand control device embedded in the furniture body, wherein the speaker is tilted relative to the mask in a direction toward the user's ear.

[0025] By adopting the above solution, with the speakers facing the user's ears, sound can be transmitted more directly to the user's ears, reducing scattering and attenuation during propagation. Just like pointing a megaphone directly at a target audience, the sound reaches the user's ears more concentratedly, allowing the user to hear sound details more clearly. It also effectively reduces sound reflection and interference within the sofa itself or its surrounding environment, avoiding reverberation and noise. For furniture with multiple speakers, positioning all speakers towards the user's ears can better create a stereo effect.

[0026] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The tilted design between the speaker and the speaker grille fully considers ergonomic principles. When users sit or lie on furniture to rest or entertain themselves, their heads are usually in a tilted position. This tilted speaker design allows sound to be transmitted to the ears more directly and effectively, avoiding scattering and attenuation caused by the mismatch between the direction of sound propagation and the position of the user's ears. This improves the efficiency of sound propagation. Because the tilted design of the speaker improves the efficiency of sound propagation, users do not need to turn the volume up too high to obtain a clear listening effect, thereby reducing the energy consumption of the audio system and conforming to the concept of energy conservation and environmental protection. 2. Due to the improved sound propagation efficiency, users can achieve a better listening experience without turning up the volume. Excessive volume not only increases energy consumption but can also affect sound quality and cause distortion. This handheld device, through optimized speaker settings, reduces energy consumption while ensuring sound quality, allowing users to enjoy a clear and pure audio experience. It also reduces auditory fatigue caused by prolonged high-volume listening and improves comfort during extended periods of rest or entertainment. 3. The speaker is closer to the mask and the center point is relatively low. This design allows the sound to propagate more smoothly, avoiding the sound from accumulating inside the furniture and causing a "muffled" sound. This further improves the listening experience. The more direct and effective sound propagation can better create an immersive audio experience. Whether watching movies, listening to music, or playing games, users can feel as if they are in the corresponding scene, enhancing the immersiveness of the entertainment experience. 4. The tilted speaker design can optimize the internal space layout of the hand control device to a certain extent. It does not require additional space to ensure sound propagation, making the structure of the hand control device more compact and easier to embed into furniture, thus saving furniture space.

[0035] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0036] Please refer to Embodiment 1 of this utility model. Figures 1 to 4As shown, a speaker control device is provided, including a housing 1, a speaker module 2, and a control unit 3. The housing 1 is composed of a base portion 11 and a face mask 12 fastened together by a snap-fit ​​structure. The base portion 11 forms a receiving cavity 111 inside, and the side wall of the receiving cavity 111 is provided with a first snap-fit ​​portion 112. The edge of the face mask 12 extends out to form a mounting plate that can cover the circumference of the base portion 11. The mounting plate is provided with a matching second snap-fit ​​portion 123 corresponding to the first snap-fit ​​portion 112. The housing 1 is used to be embedded in furniture, and the face mask 12 is exposed on the surface of the furniture. Optionally, one of the first snap-fit ​​portion 112 and the second snap-fit ​​portion 123 is a snap-fit ​​protrusion, and the other is a snap-fit ​​groove that snaps with the snap-fit ​​protrusion. In this embodiment 1, the first snap-fit ​​portion 112 consists of two snap-fit ​​protrusions, and the second snap-fit ​​portion 123 consists of two rectangular snap-fit ​​grooves. During installation, align the snap-fit ​​protrusion with the snap-fit ​​slot and push and press until a "click" sound is heard to indicate that the assembly is complete.

[0037] It should be noted that in other embodiments, the specific structure and number of the first snap-fit ​​part 112 and the second snap-fit ​​part 123 are not limited, as long as the snap-fit ​​can be completed. In this embodiment 1, the furniture is preferably a sofa chair, but in other embodiments it can also be a bed or other furniture products.

[0038] In some embodiments, the audio module 2 is disposed within the receiving cavity 111. The audio module 2 includes a speaker 21 mounted facing the mask 12, and the speaker 21 is inclined relative to the mask 12. The control unit 3 is disposed on the mask 12. By tilting the speaker 21 relative to the mask 12, when the user is sitting or lying on the furniture to rest or entertain, the sound can be transmitted to the human ear more directly and effectively, improving the sound propagation efficiency. The user can obtain a better listening effect without turning up the volume, which reduces energy consumption and ensures sound quality. Due to the tilted setting, the speaker 21 can be closer to the mask 12, and the center point is relatively low, achieving the maximum volume and avoiding the situation of "muffled" sound due to the sound not being able to escape.

[0039] In this embodiment 1, the mask 12 features a partitioned surface design, dividing it into two spaced-apart left and right sections: a sound-emitting area 121 and a control area 122. The sound-emitting area 121 corresponds to the audio module 2, and the control area 122 corresponds to the control unit 3. This clear partitioning allows users to quickly distinguish between different functional areas. When operating the control unit 3, it is less likely to accidentally touch the sound-emitting area 121, thus avoiding potential audio system malfunctions or sound interruptions due to accidental touches. The sound-emitting area 121 includes several sound holes 1211, which are strip-shaped and radially distributed along the center of the sound-emitting area 121, allowing sound to propagate at a wider angle. Compared to a design where the sound holes 1211 are concentrated in one direction or a small area, this layout allows sound to cover a larger space. The radial distribution also reduces blind spots in sound propagation. Sound is emitted from strip-shaped sound outlets 1211 in different directions, complementing each other and making the sound distribution more even throughout the space. Whether near furniture or at a distance, users can enjoy a better auditory experience. At the same time, the more reasonable layout can disperse stress and reduce the risk of damage to the mask 12 due to excessive local stress.

[0040] In some embodiments, the control unit 3 includes a knob unit 5, a button unit 4, and a circuit board 31. The button unit 4 is located between the knob unit 5 and the sound output area 121, allowing the user to quickly distinguish different functional areas during operation. The button unit 4 can be quickly located, avoiding misoperation due to confusion of functional areas during operation, thus improving operational efficiency and accuracy. In this embodiment 1, the mask 12 is also designed with an LED strip 6. The position of the LED strip 6 includes, but is not limited to, surrounding the edge of the mask 12, the edge of the knob unit 5, or the edge of the sound output area 121. This embodiment does not make specific limitations. The LED strip 6 is electrically connected to the control unit 3, and the control unit 3 can freely adjust the color, brightness, and flashing frequency of the LED strip 6. This intelligent operation allows users to experience the charm of technology. When used at night, the LED strip 6 can serve as an auxiliary lighting tool. The LED strip 6 can also be used to indicate the operating status of the device or provide safety reminders. The button unit 4 includes a sound / vibration switch button 41, a light button 42, a TV audio source receiver button 43, and a power interface 44. The TV audio source receiver button 43 allows playback of TV audio via 5.8G reception on the speaker controller. The light button 42 controls the ambient light's on / off state and switches between different flash frequencies, supporting RGB color adjustment and breathing effects. The sound / vibration switch button 41 toggles whether sound is played. The knob unit 5 includes a knob ring 51 and a touch panel 52. Buttons for controlling the seat are located below the touch panel 52, and indicator patterns are displayed on the side of the touch panel 52 facing the user. Optionally, the indicator pattern corresponds to the function of the button. Alternatively, the indicator pattern can be replaced with English and / or Chinese characters corresponding to the button switch function. In this embodiment, the user can directly press the corresponding touch panel 52 according to the indicator pattern, causing the touch panel 52 to press down the button corresponding to the button unit 4, enabling the button to sense the press operation and transmit the operation signal to the circuit board 31. The knob ring 51 is sleeved on the outer periphery of the touch panel 52 and is electrically connected to the circuit board 31. The knob ring 51, sleeved on the outer periphery of the touch panel 52, forms a compact spatial layout, optimizing space design and significantly improving overall space utilization. The signal generated when the user rotates the knob ring 51 is transmitted to the circuit board 31 to control the triggering of the corresponding function.

[0041] In this embodiment 1, for more specific details, please refer to... Figure 5As shown, the circuit system of the hand-controlled device is built around the motherboard MCU and the audio MCU control unit 3, realizing functions such as power conversion, audio processing, device control, and interaction. First, an external 29V voltage is input, one path directly into the first-stage DC-DC converter circuit, which converts the voltage to provide an appropriate voltage for the power interface 44, which uses a mobile phone fast charging C port. This 29V input also provides basic power input for the subsequent motherboard MCU power supply link and other related modules. In addition, two independent 29V / 2A power supplies are configured. One path serves as the direct power source for the motor 33, ensuring stable high-power operation of the motor 33; the other path is input to the second-stage DC-DC converter circuit, which converts the voltage to power the audio MCU and related audio processing modules. The DC-DC converter circuit precisely adjusts the output voltage and current according to the voltage and power requirements of different modules such as the motherboard MCU, audio MCU, and mobile phone fast charging C port, realizing reasonable power distribution and avoiding module damage or performance abnormalities caused by voltage mismatch, ensuring that each module operates stably under rated electrical parameters. The motherboard MCU receives power from the DC-DC converter and serves as the system's basic control hub. On one hand, it outputs control signals to drive LEDs, enabling functions such as on / off switching, brightness adjustment, and color changing, based on system operating status (e.g., power-on, standby, audio playback mode) or user-defined settings. On the other hand, the motherboard MCU establishes a data exchange channel via a 485 communication interface, transmitting control commands and status feedback information to the audio MCU and other potential peripheral modules. Simultaneously, it outputs drive signals to the motor drive 32 module. After amplification and conditioning by the motor drive 32 circuit, it precisely controls the motor 33's start, stop, speed adjustment, and direction switching, meeting the mechanical movement requirements of the furniture armrests. The audio MCU receives control commands from the 485 communication and power from the DC-DC converter, serving as the control core of the audio subsystem. It integrates Bluetooth communication functionality, allowing wireless connection with external Bluetooth devices (such as mobile phones and tablets) to receive audio data streams. Furthermore, the audio MCU connects to the vibrator, HDMI interface, and LED strip 6 control circuit, enabling multi-dimensional processing and expanded applications of audio signals. The audio MCU receives or processes the audio signal and outputs it to the power amplifier circuit. The power amplifier circuit amplifies the audio signal and drives the speaker 21 to produce sound, restoring the audio content. The vibrator can generate vibration feedback in sync with the audio rhythm, enhancing the immersive audio experience. The HDMI interface is used to transmit high-definition audio and video signals (if multimedia functions are expanded), expanding the application scenarios of the audio system. The light strip 6 can synchronize the light and audio rhythms according to the frequency, amplitude and other parameters of the audio signal, creating an interactive effect of visual-auditory linkage.

[0042] After the system starts up, the power supply module completes the voltage conversion and distribution of each circuit. The main board MCU initializes and synchronizes the status of modules such as the audio MCU through 485 communication. According to the preset program or user operation command, it controls the LED lighting mode and drives the motor 33 to operate. At the same time, the audio MCU receives audio signals through Bluetooth, etc., and outputs sound through the power amplifier and speaker 21. The vibrator and light strip 6 work together to create an interactive atmosphere. When a device is connected, the mobile phone fast charging C port charges it according to the set parameters. Under the collaborative control of the main board MCU and the audio MCU, each module realizes the organic integration of power supply, control, audio processing, interactive feedback and other functions, ensuring the stable and efficient operation of the handrail audio circuit system.

[0043] In some embodiments, to facilitate the rotation of the knob ring 51, protrusions or grooves are provided on the surface of the knob ring 51 to increase rotational friction.

[0044] In some embodiments, a mounting bracket 113 for assembling a speaker 21 is provided within the receiving cavity 111. The edge of the mounting bracket 113 is fixed to the edge of the speaker 21, and the fixing method includes, but is not limited to, adhesive fixing, screw fixing, or snap-fit ​​fixing. The edge of the mounting bracket 113 is also inclined so that the speaker 21 can be tilted relative to the mask 12 after assembly, and the tilt angle is controlled to be 10°-60°. Since different users have different postures and head tilt angles on furniture, the tilt angle range of 10°-60° can cover most users' usage scenarios. When the space in the base part 11 of the furniture is relatively compact, a smaller tilt angle, such as 10°-20°, can ensure the normal operation of the speaker 21 without occupying too much space. When the space is relatively ample, a larger tilt angle, such as 30°-60°, can further optimize the sound propagation effect. In this embodiment 1, the tilt angle between the speaker 21 and the mask 12 is 20°. The 20° tilt angle is ergonomically designed to better direct the sound emitted by the speaker 21 towards the user's ear. When a user reclines in a relaxed position on the furniture with their head tilted back at a certain angle, the 20° tilted speaker 21 allows the sound propagation direction to better match the user's ear position, reducing sound scattering and attenuation during propagation. This ensures that the sound enters the ear directly and clearly, improving sound propagation efficiency. The 20° tilt angle allows the sound to propagate at a more suitable angle, reducing the number of reflections within the interior space, presenting sound details more clearly, and reducing noise interference.

[0045] It should be noted that in this embodiment 1, the mask 12 has a first direction along its length and a second direction along its width. The first direction is perpendicular to the second direction. When selecting the folding angle of the speaker 21, it can be folded along the first direction, folded along the second direction, or folded first in the first direction and then folded in the second direction. Each folding angle is between 10° and 60°, preferably 20°. This angle ensures that the sound flow is not excessively blocked and is directed towards the ear, providing a better user experience. In other embodiments, the first and second directions include, but are not limited to, the length and width directions, and can be any two perpendicular directions of the mask 12. Similarly, the edge inclination of the mounting bracket 113 is consistent with the inclination direction of the mask 12.

[0046] This utility model also relates to a piece of furniture, including a furniture body and a speaker control device embedded in the furniture body. After assembly, the speaker cover 12 is flush with the furniture surface. The speaker 21 is tilted relative to the speaker cover 12 towards the user's ear. In this embodiment 1, the furniture is specifically a sofa body with a seating area for the user to sit or lie in. The speaker 21 is tilted relative to the speaker cover 12 towards the seating area, facing the user's ear within the seating area. The speaker 21 facing the seating area and towards the user's ear allows sound to travel more directly to the user's ear, reducing sound scattering and attenuation during propagation. It's like pointing a loudspeaker directly at a target audience; the sound reaches the user's ear more concentratedly, allowing the user to hear the details more clearly. It also effectively reduces sound reflection and interference within the sofa body or its surrounding environment, avoiding reverberation and noise. For sofas with multiple speakers 21, the speakers 21 facing the seating area can better create a stereo effect.

[0047] When in use, the user rotates the knob unit 5 to activate the audio module 2. The sound is emitted through the speaker 21, projected directionally through a 20° tilt angle, and diffused through the radial sound outlet 1211 to reach the user's ears in the seating area. At the same time, the brightness of the light strip 6 changes dynamically with the volume, which can form an audio-visual linkage feedback. Meanwhile, the audio source button 43 can connect to the TV signal with one click, realizing the effect of TV sound effect access.

[0048] In some embodiments, the furniture may also be a bed, in which case the speaker control is embedded in the headboard and tilted towards the pillow to better direct sound to the listener's ears. Of course, in other embodiments, the furniture can be anything else, as long as the speaker control is oriented towards the listener's ears.

[0049] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The tilted arrangement between the speaker 21 and the mask 12 fully considers ergonomic principles. When users sit or lie on furniture to rest or entertain themselves, their heads are usually in a certain tilted position. This tilted arrangement of the speaker 21 allows sound to be transmitted to the ears more directly and effectively, avoiding scattering and attenuation caused by the mismatch between the direction of sound propagation and the position of the user's ears, thus improving the sound propagation efficiency. Because the tilted arrangement of the speaker 21 improves the sound propagation efficiency, users do not need to turn the volume up too high to obtain a clear listening effect, thereby reducing the energy consumption of the audio system and conforming to the concept of energy conservation and environmental protection. 2. Due to the improved sound propagation efficiency, users can achieve a better listening experience without turning up the volume. Excessive volume not only increases energy consumption but can also affect sound quality and cause distortion. This handheld device, by optimizing the speaker 21 settings, reduces energy consumption while ensuring sound quality, allowing users to enjoy a clear and pure audio experience. It also reduces auditory fatigue caused by prolonged high-volume listening and improves comfort during extended periods of rest or entertainment using the furniture. 3. The speaker 21 is closer to the mask 12 and the center point is relatively low. This design allows the sound to propagate more smoothly, avoiding the sound from accumulating inside the furniture and becoming "muffled". This further improves the listening experience. The more direct and effective sound propagation can better create an immersive audio experience. Whether watching movies, listening to music or playing games, users can feel as if they are in the corresponding scene, enhancing the immersiveness of the entertainment experience. 4. The tilted design of speaker 21 can optimize the internal space layout of the hand control device to a certain extent. It does not require additional space to ensure the sound propagation effect, making the structure of the hand control device more compact and easier to embed into furniture, thus saving space inside the furniture.
