Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] It should be noted that the terms "first", "second", etc. in the present invention are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present disclosure described herein can be implemented in an order other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure.

[0026] See also Figures 1 to 7 In an embodiment of the utility model, a tweeter with a built-in horn comprises a speaker housing 1; a woofer 2, a tweeter 3 and a horn 4 are arranged inside the speaker housing 1; a sound inlet end of the horn 4 faces a sound outlet of the tweeter 3, and a sound outlet end of the horn 4 extends to the outside of the speaker housing 1; and a sound channel 5 with an L-shaped cross section is arranged inside the speaker housing 1; and the sound inlet end of the sound channel 5 faces the woofer 2, and the sound outlet end of the sound channel 5 is connected to the outside.

[0027] Specifically, the speaker housing 1 provides support and protection for the tweeter 3, the woofer 2 and the horn 4; they are arranged inside the housing to form an integrated acoustic system; the woofer 2 is responsible for producing low-frequency sounds; the tweeter 3 is responsible for producing mid-high to high-frequency sounds; the horn 4 can increase the projection and diffusion effects of the sound produced by the tweeter 3; the sound inlet end of the horn 4 is aligned with the sound outlet of the tweeter 3, while the sound outlet end extends to the outside of the speaker housing 1, more effectively guiding the sound into the surrounding environment; the L-shaped sound channel 5 is used to process the bass sound, its sound inlet end is aligned with the woofer 2, and the sound outlet end is connected to the outside, which can improve the bass effect and enhance the diffusion of the bass to a certain extent;

[0028] Furthermore, a first mounting piece 6 and a second mounting piece 7 are respectively formed at two ends of the tweeter 3; the first mounting piece 6 is extended upward, and the second mounting piece 7 is extended downward.

[0029] Specifically, the first mounting plates 6 are a part for mounting the tweeter 3; they are extended upward to provide some additional support or fixation so that the tweeter 3 can be firmly mounted at the corresponding position inside the speaker housing 1; the second mounting plates 7 are similar to the first mounting plates 6, but they are extended downward to provide additional support or fixation to ensure that the tweeter 3 remains stable in the mounting position inside the speaker housing 1.

[0030] Furthermore, the horn 4 has a sound amplification channel 8 inside, and the width of the sound amplification channel 8 gradually increases from the sound input end of the horn 4 to the sound output end of the horn 4 .

[0031] Specifically, the sound amplification channel 8 is intended to improve the projection and diffusion effects of sound; the sound will be focused and amplified when passing through the horn 4, and the sound amplification channel 8 can further enhance this effect; the sound can be guided from the tweeter 3 to the sound output end of the horn 4, while expanding the range and coverage area of ​​the sound; the channel width gradually increases from the sound input end to the sound output end of the horn 4, which can produce a gradual acoustic effect; when the sound passes through the sound amplification channel 8, as the channel width increases, the pressure and speed of the sound will gradually increase, thereby producing a more focused and powerful sound; the sound can better fill the entire space and provide more uniform and coherent acoustic coverage.

[0032] Furthermore, the speaker housing 1 includes an upper cover 9 and a lower cover 10 corresponding to the upper cover 9; the groove of the sound channel 5 is formed on the lower cover 10; and a duct sheet 11 is provided to seal and cover the groove of the sound channel 5; and the cross-section of the duct sheet 11 is also L-shaped.

The slot of the sound channel 5 is formed on the lower cover 10. The air duct sheet 11 is designed to be sealed and covered with the slot of the sound channel 5, which can ensure that the sound in the sound channel 5 will not leak or be disturbed by the outside world, and prevent dust or debris from entering the sound channel 5, thereby maintaining stable and clear sound quality. The design of the air duct sheet 11 is similar to that of the sound channel 5, and the cross-section is also L-shaped, which helps to provide better acoustic effects and ensure the sealing and matching between the air duct sheet 11 and the sound channel 5. Setting the air duct sheet 11 to be L-shaped can increase the path length of the sound propagation in the pipe. For low-frequency sounds, a longer sound path can lead to an enhancement of the bass frequency because low-frequency sounds are more easily propagated along a longer path.

[0034] Furthermore, a plurality of mounting brackets 12 with a C-shaped cross section are provided at both ends of the loudspeaker housing 1 ; and a rubber sleeve 13 for protection is installed on each of the mounting brackets 12 .

[0035] Specifically, a mounting bracket 12 having a C-shaped cross-section is located at both ends of the speaker housing 1, and there are several of them to provide multiple installation options and better stability; the C-shaped design makes installation more convenient because it can accommodate various types of installation accessories or fixtures; the rubber sleeve 13 installed on the mounting bracket 12 plays a protective role to prevent the speaker housing 1 from being damaged or scratched during installation; the rubber material has good cushioning and shock absorption properties, which can effectively reduce the impact of external impact on the speaker housing 1, while protecting the surrounding surface from scratches or wear; the speaker will vibrate when working, and the rubber sleeve 13 can act as a buffer to reduce the vibration transmitted to the bracket or housing, thereby maintaining the clarity and accuracy of the audio.

[0036] Furthermore, a cable 14 electrically connected to the tweeter 3 and the woofer 2 is provided, and the other end of the cable 14 extends to the outside of the speaker housing 1 .

[0037] Specifically, the cable 14 is used to connect the tweeter 3 and the woofer 2 to other audio devices outside the speaker housing 1; in this way, the speaker can receive electrical signals from the audio device and convert them into sound output; one end of the cable 14 is connected to the tweeter 3 and the woofer 2, and the other end extends to the outside of the speaker housing 1, so that the user can easily connect the speaker to an external audio device, such as an audio amplifier, an audio receiver or other audio sources.

[0038] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
