[0002] In modern corporate office environments, conference room audio equipment is an essential component. A high-quality conference room audio system can provide clear and smooth audio effects for meetings, thereby improving communication efficiency and decision-making quality. Among the many types of conference room audio equipment, ceiling speakers and column speakers are two common types. Ceiling speakers are audio equipment installed on the ceiling of the conference room. Their main features are their compact and beautiful appearance, which does not take up floor space. Ceiling speakers usually adopt a suspended design and can be directly installed on the ceiling, maintaining a certain distance from the ceiling to avoid sound pollution. In addition, ceiling speakers have a larger coverage area and can provide a uniform audio effect for the entire conference room.
[0003] Existing ceiling speakers can cause distortion when the sound pressure level is increased, resulting in a decrease in the dynamic range of the sound. They also cannot adjust the direction of sound diffusion according to needs. When sounds are emitted simultaneously, they cannot be heard by the listener at the same time, which will cause noise to be generated in the original sound. Therefore, there is an urgent need for a variable built-in horn waveguide speaker to improve the above problems. Summary of the Invention
[0004] The purpose of this invention is to at least address one of the aforementioned technical deficiencies.
[0005] Therefore, one object of the present invention is to provide a variable built-in horn waveguide speaker to solve the problems mentioned in the background art and overcome the shortcomings of the prior art.

[0009] The present invention is further configured such that: the bottom of the pad is provided with a cavity, the support column and the inverted tube are integrated, and the voice coil is movably connected to the outside of the support column.
[0010] The present invention is further configured such that: the fixing mechanism includes a baffle, a retaining ring is provided on one side of the baffle, and a limiting groove and a connecting groove are formed inside the retaining ring.
[0011] By adopting the above technical solution, the fixing mechanism includes a baffle, which facilitates fixing to the interior of the ceiling.
[0012] The invention is further configured such that: the steel mesh is snapped into the inside of the limiting groove, the edge of the horn is snapped into the inside of the connecting groove, the deflector is disposed at the bottom of the horn, and the baffle is snapped into the outside of the retaining ring.
[0013] By adopting the above technical solution, the steel mesh is attached to the inside of the limiting groove, which prevents the steel mesh from falling off.
[0014] The present invention is further configured such that: the transmission mechanism includes a XLR port and a sound channel, a honeycomb ball is provided at the bottom of the sound channel, a connecting post is provided on one side of the honeycomb ball, and a wire harness is provided on one side of the XLR port.

[0017] In summary, the beneficial technical effects of the present invention are as follows:
[0018] 1. This variable built-in horn waveguide speaker, by adding a speaker, emits sound; by adding a horn waveplate, it increases the sound decibel level; by using a passive radiator and a resonant cavity in combination, it expands the low-frequency limit and improves the resonance effect of the sound, making the sound quality fuller; by adding a voice coil, it improves the sound quality. By using the above structure, the dynamic range of the mid-high frequencies is increased and the sound is propagated in a more focused direction. By utilizing the shape of the speaker and adding a horn waveplate and a built-in waveguide to the mid-high frequency generating part of the speaker, the upper limit of sound pressure level is effectively increased, while distortion is reduced, the dynamic range is increased, and the sound is clearer and more powerful.
[0019] 2. This variable built-in horn waveguide speaker uses a built-in waveguide plate to control the direction of sound propagation, and an XLR port to provide high-quality audio signal transmission. The combination of the sound channel and the honeycomb sphere optimizes sound diffusion. By using this structure, the direction of the horn plate and the built-in waveguide plate can be changed, allowing the sound to propagate more concentratedly in the desired direction. This helps control the direction of sound diffusion, reduces the impact of environmental noise, and ensures that the sound can reach a specific area.

In this embodiment, the speaker 4 emits sound waves, the front baffle 5 fixes the horn waveguide 6, and the horn waveguide 6 increases the sound decibel and changes the direction of the sound waves.
[0030] Reference Figure 2 and Figure 3 The support mechanism 2 includes a pad 13, a support column 15 is provided on the top of the pad 13, a deflector tube 16 is provided on the top of the support column 15, and a voice coil 17 is provided on the outside of the support column 15. In this embodiment, the support column 15 serves to support the speaker 4, the deflector tube 16 serves to enhance the low frequency effect, and the voice coil 17 serves to convert the electrical signal into mechanical vibration.
[0031] Reference Figure 2 and Figure 3 The bottom of the pad 13 is provided with a cavity 14, the support column 15 and the deflector tube 16 are integrated, and the voice coil 17 is movably connected to the outside of the support column 15. In this embodiment, the pad 13 plays the role of fixing the support column 15.
[0032] Reference Figure 2 and Figure 3 The fixing mechanism 11 includes a baffle 18, with a retaining ring 19 on one side of the baffle 18. The retaining ring 19 has a limiting groove 20 and a connecting groove 21 inside. The steel mesh 7 is engaged inside the limiting groove 20, and the edge of the horn 4 is engaged inside the connecting groove 21. The deflector pipe 16 is located at the bottom of the horn 4.

In this embodiment, the baffle 18 facilitates the fixing of the housing 1, the retaining ring 19 provides a limiting function, the limiting groove 20 fixes the mesh 7, and the connecting groove 21 fixes the horn 4.
[0033] Reference Figure 2The transmission mechanism 12 includes a XLR port 22 and a sound channel 23. A honeycomb ball 24 is located at the bottom of the sound channel 23, and a connecting post 25 is located on one side of the honeycomb ball 24. A wire harness 26 is located on one side of the XLR port 22. The XLR port 22 is located inside the housing 1, and the connecting post 25 is engaged with the inside of the sound channel 23.

[0034] The implementation principle of this embodiment is as follows:
[0035] Connect the device to the playback device using a cable that connects to the XLR connector 22. The XLR connector 22 is an audio connector used in professional audio systems to transmit various audio signals. After the audio signal is transmitted to the speaker 4, it is converted into sound waves and emitted, which can be heard by people. When it is necessary to change the direction of sound wave diffusion, the direction of the built-in horn waveguide 6 is changed, and in conjunction with the front baffle 5, the direction of the sound wave can be changed while reducing the influence of environmental noise. At the same time, it ensures that the sound can be transmitted to a specific area, and the efficiency of mid-high frequencies can be increased by more than 3dB. This greatly increases the upper limit of sound pressure level, while reducing distortion and increasing dynamic range, making the sound clearer and more powerful. The passive radiator 8 is a sound-generating element without a driving system. It enhances the low-frequency effect through resonance. In conjunction with the resonant cavity 9 and the honeycomb ball 24, it improves the resonance effect of the sound, reduces the sound wave reflection and standing wave phenomenon inside the speaker, thereby improving the sound quality.
[0036] Compared with the prior art, the present invention has the following advantages:
[0037] By adding a speaker 4, sound is emitted; by adding a horn waveplate, the sound decibel level is increased; by using a passive radiator 8 in conjunction with a resonant cavity 9, the low-frequency limit is extended and the resonance effect of the sound is improved, making the sound quality fuller; by adding a voice coil 17, the sound quality is improved. Using the above structure, the mid-to-high frequency dynamic range is increased, and the sound propagates in a more focused direction. Utilizing the shape of the speaker 4, a horn waveplate and a built-in waveguide are added to the mid-to-high frequency generating section of the speaker 4, effectively increasing the upper limit of sound pressure level, reducing distortion, and increasing the dynamic range, making the sound clearer and more powerful. The built-in waveguide controls the direction of sound propagation. The XLR connector 22 provides high-quality audio signal transmission. The sound channel 23 and the honeycomb dome 24 work together to optimize the sound diffusion effect. By using the above structure, the direction of the horn waveplate and the built-in waveguide can be changed, allowing the sound to propagate in a more focused direction. This helps control the direction of sound diffusion, reduces the impact of environmental noise, and ensures that the sound can reach a specific area.
