Description

Technical Field

[0001] This invention is classified under the field of audio player engineering, namely multimedia systems, and is applicable to audio file reproduction. Background Technology

[0002] The device proposed in this invention is comparable to a portable multimedia acoustic wireless system, such as the JBL Charge-4 speaker.

[0003] The manufacturer claims that the main function is:

[0004] - A wireless receiver that transmits signals using the Bluetooth signal streaming protocol, which allows audio signals to be played from an external device that is capable of audio playback and equipped with a Bluetooth protocol data transmitter.

[0005] - 20 hours of wireless playback capability, using a USB-rechargeable battery.

[0006] Regarding the JBL Charge-4 speaker:

[0007] - The internal battery needs to be charged. The device takes 4 hours to fully charge after the battery is depleted.

[0008] - It does not have a built-in audio player;

[0009] - It does not have a built-in memory card reader;

[0010] - It does not have a built-in self-sustaining power supply, which allows the device to be used without any external power or connection to an external power source.

[0011] This is the main and most obvious drawback of the product being compared to this invention.

[0012] The lack of a mechanically driven DC generator is the main difference between the benchmark product and the technical solution of this invention. This DC generator allows the use of the device without (periodic or continuous) charging.

[0013] The audio channel switching is set via a mechanical switch and sent to the audio file playback device via the device's microcontroller.

[0014] Another comparable product of the present invention is a playback device comprising a housing, a component for reading and writing optical discs, a processor for digital signal processing, a storage device, an editing tool for data stored in the memory, a display, and an audio output structure. The difference between this comparable product and the prototype of the present invention lies in the USB data interface for accessories, including a serially connected connector, a port, and an additional digital signal processor. The USB connector is designed to enable the connection of accessories, primarily storage devices. The additional digital signal processor is designed to convert and save multimedia data in the accessory storage device through editing (Russian Utility Model Patent No. 112787, Publication Date: January 20, 2012).

[0015] A significant drawback of this comparable product is its undisclosed operating principle: it requires the power grid, dry cell batteries, or rechargeable batteries. Therefore, it lacks versatility.

[0016] The distinguishing technical features of this invention are the ability to always mechanically generate electrical energy, which is essential for audio signal reproduction, and the ability to switch audio channels by applying mechanical action on the playback device.

[0017] The prototype of this invention is a portable microphone with a main housing and a clip. The main housing contains a battery for the portable microphone. Therefore, the portable sound module can be powered independently. The clip is attached to the main housing and configured to snap into an external object. Thus, the portable sound module can be attached to an external object (US Patent No. US20110075877A1, Publication Date: June 14, 2010).

[0018] A significant drawback of this prototype is the existence of batteries designed with limited self-sustaining operating time, requiring subsequent charging. The battery's lifespan is also limited.

[0019] The purpose of this invention is to eliminate the shortcomings of comparable products and prototypes.

[0020] The technical advantage of this invention is that it expands its functionality and versatility:

[0021] - Capable of operating without a long-term power source, such as a battery;

[0022] - Capable of playing audio files located in built-in or removable drives;

[0023] - It can connect to external audio sources to mix and reproduce signals and external source signals (e.g., connect a microphone via the device's standard connector and transmit a signal to the device's speaker via an amplifier, and the signal from the microphone can be mixed with the signal reproduced by the device, i.e., the so-called "karaoke" function).

[0024] - It can charge the battery of an external device from the built-in generator via a universal connection port, such as a USB port, etc.

[0025] - It can connect to power accessories via a common connection port, such as USB, etc.

[0026] - It can switch channels on disconnected units, in other words, pre-installed channels without the need for a start-up device.

[0027] Interactivity and user engagement: Because of the complete immersion in the process, users are given the opportunity to feel like musicians, just like performing an instrument. Summary of the Invention

[0028] A mechanical multimedia audio player is characterized by having a housing that houses an interconnected mechanically driven generator, a curved handle rigidly connected to the generator shaft, a voltage limiter, a power converter, a charging port, a memory card reader, an amplifier, an audio speaker, a display, a control board, a microcontroller, a switch board, an audio player, and a mixer.

[0029] The enclosure serves as both a functional enclosure for the speaker system and a frame and protective housing for the device's electronic components.

[0030] The end features a curved handle for the generator drive, an audio signal input section, and connectors for external accessories;

[0031] The upper part features a control panel, information display, memory card reader slot, and audio file switching button;

[0032] The audio speakers are located at the front, and each audio speaker is covered with a protective acoustic material mesh;

[0033] The generator drive's bending handle is configured to transmit human muscle force to the generator core, thereby transferring mechanical energy to generate electrical energy. The electrical energy then passes through a voltage limiter into a capacitor to supply power to the device's circuitry.

[0034] The microcontroller is designed to have the ability to read parameters based on the control program: the start / stop and speed of the generator driver, the start of the audio file playback device when the driver starts to rotate, the stop of playback when the driver stops rotating, the increase of playback volume when the driver's rotation speed increases and the decrease of playback volume when the driver's rotation speed decreases.

[0035] The device is designed to read information from a memory card installed in a memory card reader slot;

[0036] The channel number used for playback is set by a switch on the control panel and sent to the audio player via a microcontroller;

[0037] The display shows the channel sequence number played on the memory card, the speed of the generator driver, and the intensity of the generated electrical energy;

[0038] Therefore, the microcontroller controls the reading of data and transmits the information to the display.

[0039] The outer shell is rectangular in shape and is made of wood, plastic, metal, or a combination of these materials, with decorative elements.

[0040] The curved handle is located on the right or left side of the housing.

[0041] In this case, the device has a shoulder strap mounted on the housing. Attached Figure Description

[0062] A mechanical multimedia audio player (device) is characterized by having a housing that houses interconnected: a mechanically driven generator, a curved handle (crank) rigidly connected to the generator shaft, a voltage limiter, a power converter, a charging port, a memory card reader, an amplifier, an audio speaker, a display, a control board, a microcontroller, a switch board, an audio player, and a mixer.

[0063] The enclosure serves as both a functional shell for the speaker system and a framework and protective housing for the device's electronic components.

[0064] The end features: a curved handle for the generator drive, a wire input for audio signals, and a connector for connecting external accessories.

[0065] A power converter changes the voltage level of a constant current source. A general-purpose output voltage level converter is used to stabilize the voltage level in a circuit, increasing the voltage to a desired level when the initial voltage is low and decreasing the voltage to a desired level when the initial voltage is high.

[0066] The charging port is a serial standard connector used to supply electrical power to accessory devices.

[0067] The upper part features a control panel, information display, memory card reader slot, and a switch for audio files.

[0068] The audio speaker (microphone) located at the front is covered with a protective mesh made of acoustic material, which can be, for example, perforated metal mesh, perforated wood mesh, perforated plastic mesh, or a thin film fabric with sufficient sound penetration.

[0069] The generator drive's bending handle is configured to transmit human muscle force to the generator core, thereby enabling the transfer of mechanical energy to generate electrical energy. The received electrical energy passes through a voltage limiter into a capacitor and is then supplied to the device's circuitry.

[0070] The microcontroller reads parameters based on the control program: the start / stop and speed of the generator driver. The audio file playback device starts when the driver starts rotating and stops when the driver stops rotating. The playback volume increases when the driver's rotation speed increases and decreases when the driver's rotation speed decreases.

[0071] A switchboard is a component that controls the supply of electrical energy to each module of a device in the correct sequence required for proper operation.

[0072] An audio player is a standard module of an electronic device designed to play audio files and read information from a memory card installed in a memory card reader slot.

[0073] A mixer is an electronic device designed to mix audio signals from two channels and has the ability to adjust the signal level on each channel.

[0074] The channel number used for playback is set by a switch on the control panel and sent to the audio file playback device via a microcontroller.

[0075] The display shows the channel number on the memory card, the speed of the generator driver, and the intensity of the current generated by the generator. The microcontroller provides the ability to read data and transmit information to the display.

[0076] The shell has a rectangular shape and is made of wood, plastic, metal or a combination of these materials, with decorative elements such as corners, inserts and edging.

[0077] The curved handle is located on the right or left side of the housing.

[0078] The device has a shoulder strap that is mounted on the housing.

[0079] The operating principle of a mechanical multimedia audio player is as follows.

[0080] Memory cards, such as MicroSD cards, are installed in a memory card reader slot located inside the device housing.

[0081] The channel number to be played is set via the control panel switch.

[0082] The device's microcontroller reads parameters: the generator driver's start / stop and speed, and starts the audio file playback device when the driver starts rotating.

[0083] When the user increases the rotational speed of the bending handle of the generator driver, the volume of the reproduced sound will increase.

[0084] When the user reduces the speed of the bending handle of the generator driver, the volume of the reproduced sound will decrease.

[0085] When the user stops the rotation of the generator drive's bending handle via the microcontroller, the playback function automatically stops based on the control program.

[0086] When the user resumes rotation of the generator drive's bend handle, the audio file playback function automatically restarts from where it last stopped.

[0087] Use the control panel switches to change the channel number to be played.

[0088] Analysis and experiments on the samples confirm that the present invention can achieve the following technical effects: it expands functionality and versatility, interactivity and user engagement.

[0089] The technical solution proposed in this invention meets the "novelty" requirement because the overall compositional features cannot be known from the prior art in the background section of the specification.

[0090] It also meets the "creativity" requirement because, based on the current state of the technology, it is not obvious to a person skilled in the art.

[0091] It also has industrial applicability, as sample experiments have confirmed its feasibility in the field of this technology.
