Description

Technical Field

[0001] This utility model relates to the field of speaker technology, specifically to a portable speaker with good sound output. Background Technology

[0002] A speaker is a device that converts electrical signals into sound signals and is an extremely important component of an audio system. It uses a power amplifier to amplify the audio signal and then emits the sound from the speaker itself, making the sound louder. As people's living standards improve and entertainment options become more diverse, speakers are a common device for outdoor entertainment. Due to the varying usage scenarios, portable speakers are often required. To improve sound quality, various accessories are added to enhance the speaker's output. However, current speaker accessories are numerous and bulky, making them inconvenient to carry outdoors. For example, Chinese patent application number 202320870757.0, published on October 17, 2023, discloses a portable speaker with supplementary lighting, including a speaker enclosure and a supplementary light. The supplementary light and speaker enclosure are hinged together. The supplementary light emits light, and the speaker enclosure plays audio. The speaker enclosure includes a main body and a top platform, which are vertically connected to the main body and protrude in a direction away from the main body. The supplementary light forms a hollow slot, which is through-hole for the top platform to be embedded in. When stored, the top cabinet has a hollow groove to reduce space occupation and facilitate the carrying and storage of the entire speaker. When in use, since the fill light is fixed to the top cabinet, the user can directly touch the fill light and apply a swinging force to make the fill light swing relative to the speaker body to a certain angle, thereby turning on the fill light and achieving the fill light function. In this way, the operation is simple and quick, greatly facilitating the use of the fill light and enhancing the practicality of the speaker.

[0003] This speaker achieves portability through its foldable structure. However, existing speakers, in order to facilitate portability, usually retain basic sound output functions, reducing the size of the speaker to achieve lightness. This can easily lead to unclear sound quality. In addition, this structure uses a supplementary light on the top cover for supplementary lighting, but it cannot play video while playing audio, thus failing to provide a song selection experience. Furthermore, for song selection, the microphone needs to be carried separately, making the entire system inconvenient to carry. Summary of the Invention

[0004] This utility model provides a portable speaker with good sound output, which can mix sound to improve the clarity of pronunciation, and integrates a display screen and microphone into one unit, making it convenient to carry and use.

[0005] To achieve the above objectives, this utility model provides a portable speaker with good sound output, including a cabinet, an openable outer shell on the top of the cabinet, a display screen on the outer shell, a receiving cavity for accommodating a microphone on the side of the cabinet near the connection point of the outer shell, a mounting groove in the center of the cabinet, a top cover above the mounting groove, a cavity formed between the mounting groove and the top cover, a speaker installed in the cavity, the speaker passing through the top cover, a sound guide channel on one side of the cavity, a sound inlet on the side of the sound guide channel near the cavity, a sound outlet channel on the inner wall of the sound guide channel near the cabinet, a sound outlet corresponding to the sound outlet channel on the top cover, a baffle in the sound guide channel, one end of the baffle connected to the inner wall of the cabinet near the sound inlet, and the other end of the baffle extending to the other end of the cabinet.

[0006] The above design, by incorporating a mounting slot on the top of the cabinet and placing the speaker within it, prevents the overall size of the speaker from becoming excessively large. The top cover on the mounting slot creates a cavity between it and the cabinet. Sound emitted from the front of the speaker is output normally from the top of the cabinet, while sound from the back of the speaker is mixed within the cavity. This mixed sound is then transmitted to the outside of the cabinet via a sound guide channel. A baffle within the sound guide channel obstructs the sound during transmission, altering the transmission path and lengthening the transmission time. This ensures further mixing of the sound within the sound guide channel, resulting in a higher output sound and improved speaker clarity. The cabinet also features an openable outer shell with a display screen. A microphone housing is located on one side of the cabinet, allowing the microphone to be stored there. Closing the outer shell facilitates portability. When the display screen is needed, simply open it and remove the microphone for a song selection experience.

[0007] Furthermore, a second baffle is provided on the side of the sound guide channel near the cabinet. One end of the second baffle is connected to the inner wall of the other end of the cabinet, and the other end of the second baffle extends towards the end of the cabinet near the sound inlet, forming a sound outlet channel between the second baffle and the interior of one side of the cabinet.

[0008] The above settings, by adding a second baffle, make the sound transmission path and transmission time longer, thereby further increasing the sound mixing time and improving clarity.

[0009] Furthermore, one or more mounting posts are provided inside the cavity, and the horn is mounted on the mounting posts by screws.

[0010] The above settings, by setting up mounting posts, make it convenient to install the speaker in different positions in the mounting slot according to actual needs.

[0011] Furthermore, the speaker includes a woofer and a tweeter, with the woofer positioned at the center of the cavity and the tweeter positioned in the cavity below the woofer and perpendicular to it.

[0012] The above settings improve sound clarity by mixing the sounds from the woofer and tweeter within the cavity.

[0013] Furthermore, the outer shell is mounted on the housing via hinges.

[0014] The speaker can be easily covered by the outer casing, making it easy to carry.

[0015] Furthermore, a protrusion is provided on the side of the receiving cavity near the outer wall of the housing, and the protrusion extends to the other side of the receiving cavity, with the handheld part of the microphone being secured between the protrusion and the other side of the receiving cavity.

[0016] The above design, through the protrusion, allows the microphone to be secured, preventing it from shaking during transport.

[0017] Furthermore, a mounting surface is provided at the top of the protrusion, and a mounting hole is provided on the mounting surface. The fixed end of the hinge is connected to the mounting hole by a screw, and the movable end of the hinge is connected to the outer shell.

[0018] The above configuration, by providing a mounting surface on the protrusion, allows for the installation of the hinge, saving space, and also allows the protrusion to limit the movement of the microphone. Attached Figure Description

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0024] Example 1.

[0025] like Figure 1-4As shown, a portable speaker with good sound output includes a cabinet 1. A mounting groove 11 is provided at the center of the cabinet 1, and a top cover 12 is provided above the mounting groove 11. A cavity 13 is formed between the mounting groove 11 and the top cover 12. A speaker 2 is installed within the cavity 13. The speaker 2 includes a woofer 21 and a tweeter 22. The woofer 21 is located at the center of the cavity 13, and the tweeter 22 is located below the woofer 21 within the cavity 13 and is perpendicular to the woofer 21. By mixing the sounds from the woofer 21 and the tweeter 22 within the cavity 13, the clarity of the sound output is improved. The speaker 2 is installed through the top cover 12. A sound guide channel 3 is provided on one side of the cavity 13. A sound inlet 31 is provided on the side of the sound guide channel 3 near the cavity 13. A sound outlet channel 32 is formed on the inner wall of the sound guide channel 3 near the cabinet 1. A sound outlet 30 corresponding to the sound outlet channel 32 is provided on the top cover 12. A baffle 33 is provided in the sound guide channel 3. One end of the baffle 33 is connected to the inner wall of the cabinet 1 near the sound inlet 31, and the other end of the baffle 33 extends to the other end of the cabinet 1.

[0026] like Figure 2 As shown, one or more mounting posts 14 are provided within the cavity 13, and the horn 2 is mounted on the mounting posts 14 by screws (not shown in the figure). By providing mounting posts 14, it is convenient to install the horn 2 in different positions of the mounting slot 11 according to actual needs.

[0027] like Figure 1 As shown, a shell 4 is also provided on the housing 1, and the shell 4 is installed on the housing 1 by a hinge 41. The shell 4 is designed to cover the speaker 2, thus making it easy to carry.

[0028] A display 42 is provided on the outer casing 4. The display 42 is placed on the outer casing 4 so that it is easy to carry and does not affect its use.

[0029] A receiving cavity 15 for accommodating a microphone 151 is provided on the side of the housing 1 near the connection point with the outer shell 4. The receiving cavity 15 facilitates the storage of the microphone.

[0030] like Figure 4 As shown, a protrusion 16 is provided on the side of the receiving cavity 15 near the outer wall of the housing 1. The protrusion 16 extends to the other side of the receiving cavity 15, and the handheld part of the microphone 151 is secured between the protrusion 16 and the other side of the receiving cavity 15. The protrusion 16 secures the handheld part of the microphone 151, preventing the microphone 151 from shaking during carrying and transportation.

[0031] like Figure 1 and Figure 4As shown, a mounting surface 17 is provided at the top of the protrusion 16, and a mounting hole 18 is provided on the mounting surface 17. The fixed end of the hinge 41 is connected to the mounting hole 18 by a screw (not shown in the figure), and the movable end of the hinge 41 is connected to the outer shell 4. By providing a mounting surface 17 on the protrusion 16, the hinge 41 can be installed, saving space, and the protrusion 16 can limit the position of the microphone 151.

[0032] The working principle of this utility model is as follows: By setting a mounting groove 11 on the upper part of the enclosure 1 and placing the speaker 2 in the mounting groove 11, the overall size of the speaker enclosure 1 is not too large. Since a top cover 12 is set on the mounting groove 11, a cavity 13 is formed between the top cover 12 and the mounting groove 11. Therefore, the sound emitted from the front of the speaker 2 is normally output from the top of the speaker enclosure 1, while the sound emitted from the back of the speaker 2 is mixed in the cavity 13. The mixed sound is then transmitted to the outside of the speaker enclosure 1 through the sound guide channel 3. Because a baffle 33 is set in the sound guide channel 3, the sound is blocked by the baffle 33 during transmission within the sound guide channel 3. By changing the transmission path, the transmission time and path of the sound are lengthened, which ensures that the sound can be further mixed within the sound guide channel 3, thereby increasing the output sound and improving the clarity of the speaker 1. At the same time, an openable shell 4 is provided on the cabinet 1, and a display screen 42 is provided on the shell 4. A microphone 151 receiving cavity 15 is provided on one side of the cabinet 1, so that the microphone 151 can be housed on one side of the cabinet 1. The shell 4 can be closed for easy carrying. When the display screen 42 is needed, the display screen 42 can be opened and the microphone can be taken out to achieve the song selection experience.

[0033] Example 2.

[0034] In this embodiment, as Figure 3 As shown, the other structures are the same as in Embodiment 1, except that a second baffle 34 is provided on the side of the sound guide channel 3 near the enclosure 1. One end of the second baffle 34 is connected to the inner wall of the other end of the enclosure 1, and the other end of the second baffle 34 extends towards the end of the enclosure 1 near the sound inlet 31, forming a sound outlet channel 32 between the second baffle 34 and the interior of one side of the enclosure 1. By adding the second baffle 34, the sound transmission path and transmission time are made longer, thereby further increasing the sound mixing time and improving clarity.
