Description

Technical Field

[0001] The utility model relates to the technical field of speakers, in particular to a new type of anti-collision speaker. Background Art

[0002] A speaker is a type of loudspeaker, which is a transducer that converts an electrical signal into sound. A speaker is composed of an electromagnet, a coil, and a speaker diaphragm, which converts the current frequency into sound. According to the physical principle, when an electric current passes through the coil, an electromagnetic field is generated, and the direction of the magnetic field follows the right-hand rule.

[0003] After retrieval, a Chinese utility model patent with the patent application number CN202221136053.2 discloses a new type of speaker, including a chassis and a voice coil. A round iron is fixed on the chassis. Inside the round iron, a main magnet and a washer are sequentially fixed from bottom to top. There are gaps between the round iron and the main magnet and the washer. The voice coil is in a toroidal structure and is arranged in the aforementioned gap. A diaphragm is also fixed above the voice coil. Through holes Ⅰ penetrating the chassis are symmetrically arranged on both sides of the upper end of the chassis. Through holes Ⅱ penetrating the chassis are arranged on the chassis between the through holes Ⅰ and the voice coil. When the speaker emits sound, air flow can be discharged through the through holes Ⅰ to blow the ear canal, which can effectively reduce the fatigue of the ear canal and enhance the hearing experience.

[0004] Another example is a Chinese utility model patent with the patent application number CN202223433366.7, which discloses a new type of electric horn, including a housing. A coil bobbin is arranged inside the housing. An enameled wire is sleeved outside the coil bobbin. A static iron core is arranged on the coil bobbin. A moving iron core is arranged on the static iron core. A lower plate and an upper plate are installed inside the housing through screws. The lower plate contacts the upper plate. Contacts are arranged on both the upper plate and the lower plate. An insulating plate is arranged on the lower plate. A plug-in component is arranged on the housing. An armature is arranged on the moving iron core. By designing the combined use of an adjusting screw and a spring, by rotating the screw, the screw can perform a threaded movement and drive the spring to move. The spring presses the upper plate to move the upper plate, which can conveniently adjust the distance between the upper plate and the lower plate, achieve the purpose of adjusting the distance between the two contacts, and can adjust the trigger stroke of the electric horn, improving the use effect of the electric horn.

[0005] Although the existing above-mentioned speakers can meet the basic usage requirements, their anti-collision function is not good enough, the structural strength is relatively low, and when they fall and are shocked during the installation and use process, it is easy to damage the internal parts, resulting in a short service life and inconvenient for the normal use of the speakers.
