Description

Technical Field

[0001] This utility model relates to the field of speaker technology, specifically to a modular speaker that can be freely combined and upgraded. Background Technology

[0002] Traditional speakers (including Bluetooth speakers and multimedia speakers) are typically integrated designs. Multiple functional modules (including tweeters and woofers) are designed as a single unit, making installation complex and inconvenient. Users cannot assemble and disassemble the individual modules to suit their needs. When a speaker malfunctions, the entire unit must be taken to a repair shop. If the speaker modules are large, they are inconvenient to carry and transport, and also difficult for users to inspect and repair themselves. Furthermore, because these speakers cannot be upgraded in terms of sound quality, they fail to meet users' daily needs. Alternatively, as users' demands for sound quality increase, they may find that they cannot upgrade the speaker to suit their needs and preferences, leading to the original speaker becoming unused and requiring them to purchase a new one, resulting in unnecessary waste while improving sound quality. Utility Model Content

[0003] The technical problem this invention aims to solve is to provide a freely combinable and upgradeable modular speaker. This modular speaker not only facilitates user installation but also allows users to adjust it according to their needs and preferences, improving sound quality while reducing unnecessary waste. The technical solution adopted is as follows:

[0004] A modular speaker that can be freely combined and upgraded is characterized in that it includes at least one main speaker and at least one modular speaker, each modular speaker is respectively arranged in an adjacent position to the corresponding main speaker, and the modular speaker is connected to the corresponding main speaker through a detachable connection structure to form an audio connection, and each modular speaker is selected from at least one of a bass modular speaker, a midrange modular speaker, and a tweeter modular speaker.

[0005] In use, customers can choose one or two main unit speakers according to their preferences and usage scenarios, and select appropriate modular speakers (such as bass or tweeter modular speakers) based on their preferences and usage scenarios. The modular speakers are then placed adjacent to at least one main unit speaker (i.e., the modular speakers can be placed in a position that fits against the top, bottom, or side of the main unit speaker), and connected to the main unit speaker through a detachable connection structure to form a whole. At the same time, the audio signal from the main unit speaker is transmitted to the modular speaker through the detachable connection structure (the detachable connection structure can connect the audio interfaces between the main unit speaker and the modular speaker together for transmitting audio signals). Since there is no need to disassemble the equipment or connect cables, it is convenient for users to install themselves. Moreover, after purchasing the main unit speaker, users can freely combine and match modular speakers of different materials and sizes according to their preferences and usage scenarios to create suitable timbre and volume. The frequency response curve will also change with different combination methods, and there is no fixed frequency response curve. This avoids the problem of users leaving speakers idle due to dissatisfaction with the sound quality. In addition, this type of separate speaker adds a tweeter module and / or a woofer module to the main speaker, which makes the high and / or low frequencies more prominent in the frequency response curve, transforming it from a relatively flat frequency response curve to a frequency response curve similar to the "Harman curve" pursued by some HiFi enthusiasts. Adding module speakers on both sides of the main speaker can expand the sound field, which also has a good effect on improving the sound effect of the integrated Bluetooth speaker.

[0006] The speaker unit described above functions basically the same as a regular Bluetooth speaker. It can be a 2.1 channel stereo Bluetooth speaker with a built-in amplifier board. Its three speakers correspond to the left and right full-range and the center bass, respectively, forming a 2.1 stereo sound. It is suitable for simple application scenarios such as playing background music and news broadcasts. After being powered on, it can play music simply by connecting it to a mobile phone or other Bluetooth playback device.

[0007] The aforementioned tweeter module can use tweeters of different materials and styles, such as aluminum ribbon, air-driven, silk dome, and horn tweeter speakers, to highlight their different tonal styles.

[0008] The aforementioned subwoofer module speakers offer a variety of speaker diameter and power options, allowing users to choose according to their preferences and application scenarios. Examples include miniaturized module speakers with dual 3-inch speakers and diaphragms, standard bookshelf module speakers with 6.5-inch speakers, and floorstanding module speakers with 8-inch speakers, to reflect the bass response required for different music styles and room sizes.

[0009] In a preferred embodiment of this utility model, the number of main unit speakers is one; the number of modular speakers is two, namely a tweeter module speaker and a woofer module speaker; the main unit speaker is placed on top of the woofer module speaker, and the bottom of the main unit speaker is connected to the top of the woofer module speaker through a first detachable connection structure to form an audio connection; the tweeter module speaker is placed on top of the main unit speaker, and the bottom of the tweeter module speaker is connected to the top of the main unit speaker through a second detachable connection structure to form an audio connection. When installing the above-mentioned split speakers, the user can first place the main unit speaker on top of the woofer module speaker, and form an audio connection between the bottom of the main unit speaker and the top of the woofer module speaker through the first detachable connection structure, which can transmit the bass audio signal of the main unit speaker to the woofer module speaker; then place the tweeter module speaker on top of the main unit speaker, and form an audio connection between the bottom of the tweeter module speaker and the top of the main unit speaker through the second detachable connection structure, which can transmit the treble audio signal of the main unit speaker to the tweeter module speaker.

[0010] As a further preferred embodiment of this utility model, the first detachable connection structure includes a metal clip and metal feet. The metal clip is disposed on the top of the subwoofer module speaker and constitutes its audio input terminal, while the metal feet are disposed on the bottom of the main speaker and constitute its audio output terminal. When the main speaker is placed on top of the subwoofer module speaker, the metal feet engage with the metal clip. Thus, the main speaker can be fixed to the subwoofer module speaker using the engagement between the metal clip and the metal feet, and an audio connection can be established between the audio output terminal of the main speaker and the audio input terminal of the subwoofer module speaker.

[0011] As a further preferred embodiment of this utility model, the metal buckle and metal feet are made of copper.

[0012] The aforementioned first detachable connection structure can also adopt a plug and socket connection structure.

[0013] As a further preferred embodiment of this utility model, the second detachable connection structure includes a spring pin and a socket. The socket is located on the top of the main speaker and constitutes its audio output terminal, while the spring pin is located on the bottom of the tweeter module and constitutes its audio input terminal. When the tweeter module is placed on top of the main speaker, the spring pin and the socket engage. Thus, the main speaker can be fixed on top of the subwoofer module using the engagement between the spring pin and the socket, and an audio connection can be established between the audio output terminal of the main speaker and the audio input terminal of the tweeter module.

[0014] As a further preferred embodiment of this invention, the socket has a built-in magnet. Therefore, after the tweeter module speaker is placed on top of the main speaker, the magnetic force generated by the magnet on the spring pins allows the spring pins to automatically align with the socket, making the installation of the tweeter module speaker more convenient.

[0015] Because the bass module speaker generates significant vibrations, as a further preferred embodiment of this invention, the two sides of the main speaker and the two sides of the bass module speaker are connected by interlocking connectors to reduce these vibrations. This makes the connection between the main speaker and the bass module speaker more stable, resulting in less vibration.

[0016] As a further preferred embodiment of this utility model, the interlocking connector includes an upper locking component and a lower locking component that cooperate with each other; the upper locking component includes an upper support base, an upper slider, an upper adjusting handle, an upper clamping block, and an upper arc-shaped plug-in strip. The upper support base is fixed to the lower side wall of the main speaker. The lower part of the upper support base is provided with an upper arc-shaped opening, and the upper part of the upper support base is provided with an upper guide slide that communicates with the upper arc-shaped opening. The two ends of the upper guide slide are open at the two ends of the bottom surface of the upper support base. The lower end of the upper adjusting handle is provided with an upper slider, which is located in the upper guide slide and slides in cooperation with the upper guide slide. The upper clamping block is located in the upper arc-shaped opening and connected to the upper slider; the upper arc-shaped plug-in strip is located in the upper guide slide and connected to the upper slider; the lower locking component includes a lower support base, a lower slider, a lower adjusting handle, and a lower clamping block. The lower support base is fixed to the upper side wall of the subwoofer module speaker. The upper part of the lower support base has a lower arc-shaped opening, and the lower part of the lower support base has a lower guide slide communicating with the lower arc-shaped opening. The two ends of the lower guide slide open onto the top surface of the lower support base. The upper end of the lower adjustment handle has a lower slider, which is located in and slides within the lower guide slide. The lower arc-shaped connector is located in the lower guide slide and connected to the lower slider. The lower clamping block is located in the lower arc-shaped opening and connected to the lower slider. The upper arc-shaped connector can extend from the first opening of the upper guide slide and connect with the first opening of the lower guide slide. The lower arc-shaped connector can extend from the second opening of the lower guide slide and connect with the second opening of the upper guide slide. When the main speaker is placed on top of the subwoofer module, the upper arc-shaped opening of the upper support base and the lower arc-shaped opening of the lower support base face each other and together form an annular cavity. The upper and lower clamping blocks are positioned side by side within this annular cavity. When it is necessary to connect the two sides of the main speaker to the two sides of the subwoofer module via two interlocking connectors, the upper adjustment handle of the locking assembly can be moved to drive the upper slider to slide along the upper guide slide, causing the upper arc-shaped insertion strip to extend from the first end opening of the upper guide slide and engage with the first end opening of the lower guide slide. At the same time, the upper clamping block rotates a certain angle (e.g., 90 degrees) within the upper arc-shaped opening. The lower locking assembly can be adjusted by moving the lower adjustment handle, causing the lower slider to slide along the lower guide slide. This allows the lower arc-shaped connector to extend from the second end opening of the lower guide slide and engage with the second end opening of the upper guide slide. Simultaneously, the lower clamping block rotates a certain angle (e.g., 90 degrees) within the lower arc-shaped opening. This allows the interlocking upper and lower locking assemblies to be connected together. The upper and lower clamping blocks of the two interlocking connectors together clamp the upper part of the subwoofer module speaker and the lower part of the main speaker, making the connection between the main speaker and the subwoofer module speaker more stable and reducing vibration.

[0017] In another preferred embodiment of this utility model, there are two main speaker units, namely a first main speaker and a second main speaker; there is one modular speaker, which is located adjacent to the first main speaker and connected to the first main speaker via a detachable connection structure to form an audio connection. The detachable connection structure can be the same as the first or second detachable connection structure. The first and second main speaker units can be 2.1-channel stereo Bluetooth speakers, which can be paired to form a 2.0 stereo two-way speaker system. The first main speaker, when paired with the modular speaker, can enhance its volume or sound quality. In practical use, when a consumer purchases two main speaker units, they can be used together or independently. The two main speaker units can connect to different Bluetooth devices in the same or different locations to play different content, or they can be paired to form a 2.0 stereo system. In paired mode, double-clicking the pairing button disconnects the pairing mode and returns to standalone use.

[0018] Compared with the prior art, this utility model has the following advantages:

[0019] This type of split speaker adds a modular speaker to the main speaker unit. The modular speaker is placed next to the main speaker and connected to it via a detachable connection structure to form a whole. The audio signal from the main speaker is transmitted to the modular speaker through this detachable connection structure. Since there is no need to disassemble the device or connect cables, it is convenient for users to install themselves. It also allows users to adjust it according to their own needs and preferences, improving sound quality while reducing unnecessary waste, and making the high and low frequencies of the emitted frequency response curve more prominent.
