Description

Technical Field

[0001] This utility model belongs to the field of audio equipment technology, and specifically relates to an adjustable portable speaker. Background Technology

[0002] A speaker is an audio playback system that uses electronic circuitry to convert electrical signals into sound signals, providing people with a rich auditory experience. Portable speakers are miniaturized audio playback devices, widely popular for their portability and ease of carrying, making them particularly suitable for outdoor activities, travel, or everyday home use. A portable speaker refers to an audio device that is small in size, lightweight, and easy to carry. It integrates multiple components such as a sound source, amplifier, and speaker, and can independently play audio signals.

[0003] Announcement No. "CN220570653U" discloses an adjustable portable speaker, comprising a speaker housing, control buttons mounted on the top of the speaker housing, and a connection interface mounted on the side of the speaker housing. A rotating base is fixed to the outer wall of the speaker housing, and a sleeve is rotatably connected to the rotating base. A guide groove is formed inside the sleeve, and a guide slider is placed within the guide groove. A sealing strip is connected to the top of the guide slider via a connecting bracket. By installing a rotatable sleeve on the outside of the speaker housing and a slidable guide slider inside the sleeve, the guide slider can drive the sealing strip to move laterally under the elastic force of a return spring. This allows the sealing strip to be stably locked onto the outside of the connection interface, forming an effective seal. This effectively prevents foreign objects from entering the connection interface of the speaker housing during transportation, ensuring the normal use of the connection interface.

[0004] While the aforementioned utility model can effectively prevent foreign objects from entering the connection interface of the speaker housing during transportation, ensuring that the connection interface can be used normally, the connection cable is prone to falling off the connection interface under prolonged use or accidental pulling. This can lead to audio signal interruption and affect the normal use of the speaker. Moreover, frequent detachment of the connection cable will affect the normal user experience. Users need to constantly check whether the audio cable is securely connected, and may even need to repeatedly plug and unplug the connection cable to ensure a stable connection. Utility Model Content

[0005] In response to the problems mentioned in the background art, the purpose of this utility model is to provide an adjustable portable speaker to solve the problem that the connecting cable is easy to fall off the connection interface under long-term use or accidental pulling, which will cause audio signal interruption and affect the normal use of the speaker. Moreover, the frequent falling off of the connecting cable will affect the normal user experience. Users need to constantly check whether the audio cable is securely connected, and may even need to repeatedly plug and unplug the connecting cable to ensure a stable connection.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] An adjustable portable speaker includes a speaker housing, a connecting groove on the upper part of the speaker housing, a connecting interface installed at the bottom of the connecting groove, anti-derailment components symmetrically installed inside the speaker housing, control buttons installed on the side of the speaker housing, and a channel hole symmetrically opened at one end of the speaker housing. A sound intensifier is threaded to the bottom of the channel hole, a speaker is installed on one side inside the sound intensifier, a mounting frame is fixedly connected inside the channel hole, and a mesh cover is fixedly connected inside the mounting frame.

[0008] The anti-detachment component includes a movable groove, a threaded rod, a clamping block, a rotating disk, a threaded hole, a limiting block, and a limiting post. Movable grooves are provided on both sides of the connecting groove. A clamping block is slidably connected inside the movable groove, and the clamping block is slidably connected to both the movable groove and the connecting groove. A threaded rod is rotatably connected to one end of the clamping block, and a rotating disk is sleeved on the outside of the threaded rod. Limiting posts are fixedly connected to both sides of the rotating disk, and a threaded hole is provided at one end of each limiting post, penetrating the rotating disk. The threaded rod and the threaded hole are threadedly connected. A limiting block is fixedly connected to the end of the threaded rod away from the clamping block. A rotating groove is embedded in the upper part of the speaker housing, communicating with the movable groove. The rotating disk and the rotating groove are rotatably connected, which firmly fixes the connecting cable to the interface, effectively preventing loosening or detachment due to accidental pulling or vibration of the connecting cable. This ensures continuous audio signal transmission and avoids signal interruption or sound quality loss due to loose connections.

[0009] As a preferred technical solution, guide grooves are provided on both sides of the moving groove and the connecting groove, and guide blocks are fixedly connected to both sides of the clamping block. The guide blocks and the guide grooves are slidably connected. The guide grooves provide a clear path and direction for the movement of the clamping block, ensuring that the clamping block remains stable and smooth during the movement.

[0010] As a preferred technical solution, the clamping end of the clamping block is glued with a protective pad. The surface of the protective pad is provided with anti-slip protrusions. The protective pad is made of soft silicone, which can closely fit the surface of the connecting wire and effectively prevent the clamping block from causing scratches, indentations or wear to the wire during the clamping process.

[0011] As a preferred technical solution, the bottom of the speaker housing is symmetrically fixed with assembly blocks. The bottom of the assembly blocks has an assembly groove, and the mounting blocks are movably connected inside the assembly groove. The bottom of the mounting blocks is glued with anti-slip pads. The surface of the anti-slip pads is provided with anti-slip textures. The anti-slip pads are made of soft rubber, which can increase the friction between the speaker housing and the placement surface, prevent the speaker from sliding or tipping over due to vibration or external force during playback, and absorb and reduce the vibration generated when the speaker is working, prevent the vibration from being transmitted to the surrounding environment through the placement surface, reduce noise and interference, and improve sound quality.

[0012] As a preferred technical solution, the bottom of the mounting slot is symmetrically and fixedly connected with magnetic grooves, and one side of the mounting block is symmetrically and fixedly connected with magnetic blocks. The magnetic blocks and magnetic grooves are magnetically connected, which allows for timely replacement of new anti-slip pads, preventing damage to the speaker due to sliding or tipping, thereby extending the overall service life of the speaker. In addition, it allows users to choose the appropriate anti-slip pad material and type according to different placement environments, improving adaptability.

[0013] In summary, the present invention has the following main advantages:

[0014] First, in this utility model, the connector is connected to the connection interface inside the connection groove, and then the rotating disk is rotated. The rotating disk drives the limiting post to rotate. At the same time, the threaded hole and threaded rod inside the rotating disk and the limiting post rotate threadedly, thereby controlling the threaded rod to drive the clamping block to move. When the clamping block moves, the clamping block drives the guide block to slide inside the guide groove. The clamping block clamps and fixes the connecting wire, which can firmly fix the connecting wire to the interface, effectively preventing loosening or falling off due to accidental pulling or vibration of the connecting wire, ensuring continuous transmission of audio signal, and avoiding signal interruption or sound quality loss due to loose connection.

[0015] Secondly, in this utility model, the speaker housing is placed on the placement surface, so that the anti-slip pad at the bottom of the mounting block is in contact with the placement surface. When the anti-slip pad needs to be replaced, the mounting block is pulled out from the inside of the assembly slot. At the same time, the magnetic block and the magnetic groove are disconnected, and the anti-slip pad is replaced. Then, the mounting block is inserted into the assembly slot, and the magnetic block and the magnetic groove are magnetically connected, and the anti-slip pad is replaced. This allows for timely replacement of the anti-slip pad, preventing damage to the speaker due to sliding or tipping, thereby extending the overall service life of the speaker. Moreover, it allows users to choose the appropriate anti-slip pad material and type according to different placement environments, improving adaptability. Attached Figure Description
