Description

Technical Field

[0001] This utility model relates to the field of speaker technology, and more particularly to a combination speaker, which is a combination speaker formed by a dynamic baffle speaker and a phase guide speaker. Background Technology

[0002] A stereo system consists of an audio input device, a signal amplifier (power amplifier), and speakers, forming a complete system. After years of market expansion within the industry, it is now widely used in home theater systems, background music systems, multimedia audio systems, and public address systems. While there are many types of stereo systems, this has led to significant homogenization, limited sound quality, and a disconnect between physical acoustic structure and electronic tuning, making it impossible to simultaneously achieve the subtlety of a concert hall, the power of a dance hall, or the spaciousness of a stadium. Summary of the Invention

[0003] In view of the defects in the above-mentioned technology, this utility model proposes a combined audio system.

[0004] A stereo system, comprising:

[0005] At least one dynamic baffle speaker;

[0006] At least one phase-guided speaker;

[0007] Audio power amplifier;

[0008] A speaker switcher, whose input is connected to the output of an audio power amplifier, whose first output is connected to a dynamic baffle speaker, and whose second output is connected to a phase-guided speaker.

[0009] The control signal emitted by the speaker switcher enables switching between three operating modes:

[0010] First mode: Only the dynamic baffle speaker is connected to simulate the sound effect of a concert hall;

[0011] Second mode: Only the phase-guided speaker is turned on to simulate the sound effect of a nightclub;

[0012] Third mode: Simultaneously connect the dynamic baffle speaker and the phase guide speaker to simulate the sound effect of a stadium.

[0013] Preferably, it also includes a speaker switching remote control, which is wirelessly connected to the speaker switcher. The speaker switcher responds to the control signal of the speaker switching remote control to switch between the three working modes.

[0014] Preferably, the number of dynamic baffle speakers and phase-guided speakers is the same, and they are arranged in a stacked or side-by-side layout in physical space.

[0015] Preferably, the dynamic baffle speaker includes:

[0016] loudspeaker unit;

[0017] The speaker enclosure frame that secures the speaker unit;

[0018] A dynamic baffle is located in front of the speaker unit;

[0019] The suspension system connects the dynamic baffle and the speaker frame, enabling the dynamic baffle to vibrate and shift.

[0020] A mechanical coupling element connects the edge of the speaker unit cone to the central area of ​​the dynamic baffle, transmitting vibrational energy to the dynamic baffle.

[0021] Preferably, the suspension system includes:

[0022] Multiple suspension springs connect the outer periphery of the dynamic baffle to the inner wall of the speaker frame;

[0023] A support sponge, located on the back of the outer periphery of the dynamic baffle and facing the speaker frame, is used to provide support and restraint between the dynamic baffle and the speaker frame.

[0024] Preferably, the speaker switcher includes: a first output path and a second output path;

[0025] When the first control signal is received, the first output terminal path is closed, and the second output terminal path is opened at the same time.

[0026] When the second control signal is received, the first output terminal path is disconnected, and the second output terminal path is closed at the same time.

[0027] When the third control signal is received, the first output terminal path and the second output terminal path are closed simultaneously.

[0028] Technical Effects: Employing a combination of dynamic baffle and phase-guided speakers, controlled by a speaker switcher, this system can simulate three sound effects: concert hall, dance hall, and stadium. In concert hall mode, the dynamic baffle speaker operates independently, with controlled vibrations enhancing sound wave diffusion, and its suspension system suppressing resonance distortion. In dance hall mode, the phase-guided speaker operates independently, enhancing low frequencies and achieving a high peak sound pressure level to meet the demands of high-intensity rhythms. In stadium mode, dual speakers work in tandem, with the dynamic baffle speaker widening the sound field and the phase-guided speaker reinforcing low frequencies, resulting in significantly improved sound uniformity.

Detailed Implementation

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Please see Figure 1 , Figure 2 and Figure 4 The combined audio system of this embodiment includes: two dynamic baffle speakers 1, two phase-guided speakers 2, an audio power amplifier 3, a speaker switcher 4, and a speaker switching remote control 5.

[0037] The number of dynamic baffle speakers 1 and phase-guided speakers 2 are the same, and they are arranged in a vertically stacked or horizontally side by side in physical space. Preferably, the two dynamic baffle speakers 1 and the two phase-guided speakers 2 are stacked vertically, and the two dynamic baffle speakers 1 are respectively arranged on the top of the two phase-guided speakers 2.

[0038] The speaker switcher 4 has its input terminal connected to the output terminal of the audio power amplifier 3, its first output terminal connected to the dynamic baffle speaker 1, and its second output terminal connected to the phase-guided speaker 2.

[0039] The control signal emitted by speaker switcher 4 enables switching between the following three operating modes:

[0040] First mode: Only connect dynamic baffle speaker 1 to simulate concert hall sound effects.

[0041] Second mode: Only the phase-guided speaker 2 is connected to simulate the sound effect of a nightclub.

[0042] Third mode: Simultaneously connect dynamic baffle speaker 1 and phase guide speaker 2 to simulate the sound effect of a stadium.

[0043] The speaker switching remote control 5 is wirelessly connected to the speaker switcher 4. The speaker switcher 4 responds to the control signals from the speaker switching remote control 5, enabling switching between the three operating modes mentioned above. The speaker switching remote control 5 includes three mode selection buttons: concert hall button 51, dance hall button 52, and gymnasium button 53. Selecting the activation mode selection button sends control signals for three different modes to the speaker switcher 4, such as concert hall control signal, dance hall control signal, and gymnasium control signal.

[0044] The speaker switcher 4 includes: a first output path 41 and a second output path 42. During operation,

[0045] 1. When the speaker switcher 4 receives the first control signal (concert hall control signal), it closes the first output terminal path 41 and simultaneously disconnects the second output terminal path 42, connecting only the dynamic baffle speaker 1 to simulate the sound effect of a concert hall.

[0046] 2. When the speaker switcher 4 receives the second control signal (karaoke control signal), it disconnects the first output terminal path 41 and simultaneously closes the second output terminal path 42, connecting only the phase-guided speaker 2 to simulate the sound effect of a karaoke hall.

[0047] 3. When the speaker switcher 4 receives the third control signal (gymnasium control signal), it simultaneously closes the first output terminal path 41 and the second output terminal path 42, and simultaneously connects the dynamic baffle speaker 1 and the phase guide speaker 2, which can simulate the sound effect of a gymnasium.

[0048] It should be noted that the speaker switching remote control 5 can switch between the three working modes using the function keys on its control panel (concert hall button, dance hall button, and stadium button), or it can switch between the three working modes using the three mode selection buttons on the speaker switching remote control 5.

[0049] like Figure 3As shown, the dynamic baffle speaker 1 of this embodiment mainly consists of a speaker unit 11, a speaker frame 12, a dynamic baffle 13, a suspension system 14, and a mechanical coupling component 15. The speaker unit 11 is fixed to the speaker frame, the dynamic baffle 13 is located in front of the speaker unit 11, the suspension system 14 connects the dynamic baffle 13 and the speaker frame 12, enabling the dynamic baffle 13 to vibrate during operation, and the mechanical coupling component 15 (or centering support) connects the edge of the speaker unit 11's cone to the central region of the dynamic baffle 13, transferring the vibration energy of the speaker unit 11 to the dynamic baffle 13.

[0050] The suspension system 14 of the dynamic baffle speaker 1 includes multiple suspension springs 13a and supporting foam 14b. The suspension springs 13a are connected between the outer periphery of the dynamic baffle 13 and the inner wall of the speaker frame 12. Multiple supporting foams 14b are present, each elongated strip located on the back of the outer periphery of the dynamic baffle 13 and facing the speaker frame 12, providing support and restraint between the dynamic baffle 13 and the speaker frame 12. The dynamic baffle 13 is made of aluminum sheet and is rectangular. Two suspension springs 14a are positioned between the shorter sides of the rectangle and the speaker frame 12, and three suspension springs 14a are positioned between the longer sides of the rectangle and the speaker frame 12, ensuring balanced force distribution on the dynamic baffle 13.

[0051] like Figure 4 As shown, it should be noted that the phase-guided speaker 2 in this embodiment is a conventional phase-guided speaker, and the audio power amplifier 3, speaker switcher 4 and speaker switching remote control 5 are all conventional devices. Therefore, their specific structures will not be described in detail in this utility model.

[0052] This invention achieves three types of sound field effects through the coordinated operation of physical acoustic structure reconstruction and electronic switching control. The sound source signal is output, the power is amplified, and the switcher distributes the signal to the target speaker combination to produce sound, thus completing the spatial sound field reconstruction.

[0053] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
