Problems solved by technology

However, the frames of traditional loudspeakers are generally light and thin, and the rigidity is not strong, so they are easy to be damaged during assembly and use, and such a frame will easily vibrate slightly when the sound film vibrates, and the frame vibration will generate standing waves. Makes the sound from the speaker noisy, which affects the sound quality of the speaker

Embodiment Construction

[0013] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0014] see Figure 1 to Figure 3 A loudspeaker 10 provided in a preferred embodiment of the present invention includes a frame 100, a yoke 200 arranged in the frame 100, a magnet 300 fixed in the yoke 200, a washer 400 fixed on the magnet 300, and a The sound membrane 500 on the frame 100 and the voice coil 600 fixed on the sound membrane 500 .

[0015] see next Figure 4 , the frame 100 includes a frame 110 and a supporting frame 120 . The frame 110 is in the shape of a racetrack, and includes two straight frames 111 parallel to each other and two arc-shaped frames 112 respectively connecting opposite ends of the two straight frames 111 . The support frame 120 is fixedly connected to the bottom surface of the frame 110 . It includes a fixed body 121, two first extension bodies 122 extended from the fixed body 121 and respectively fixed on the two straigh...

Abstract

The invention provides a loudspeaker. The loudspeaker comprises a framework, a magnetic yoke, a voice diaphragm, a magnet and a voice coil, wherein the magnetic yoke and the voice diaphragm are fixed at the two sides of the framework respectively, the magnet is fixed in the magnetic yoke, and the voice coil is fixed on the voice diaphragm. The framework comprises a frame and a supporting frame, wherein the frame comprises two parallel straight frame bodies and two arc-shaped frame bodies connected with the opposite ends of the two straight frame bodies respectively, the supporting frame comprises a fixing body, two first extending bodies and two second extending bodies, the two first extending bodies are fixed on the two straight frame bodies of the frame respectively, the two second extending bodies are fixed on the two arc-shaped frame bodies of the frame respectively, a through hole is formed in the fixing body, and the magnetic yoke is embedded into the through hole. According to the loudspeaker, the rigidity strength of the frame is improved through the supporting frame, and therefore the overall rigidity strength of the framework is improved. Therefore, when the voice diaphragm vibrates, the framework is not prone to vibration, noise cannot be generated, the quality of sound production is high, and the framework is not prone to damage in the process of assembly and use.

Description

technical field [0001] The invention relates to a loudspeaker. Background technique [0002] At present, with the rapid development of the electroacoustic industry, people have higher and higher requirements for the sound quality of speakers. A traditional loudspeaker generally includes a frame, a sound film arranged on the frame, a voice coil connected with the sound film, and a magnet set in the frame. The magnet drives the voice coil to vibrate up and down, thereby driving the sound film to vibrate to produce sound. However, the frames of traditional loudspeakers are generally light and thin, and the rigidity is not strong, so they are easy to be damaged during assembly and use, and such a frame will easily vibrate slightly when the sound film vibrates, and the frame vibration will generate standing waves. There is noise in the sound emitted by the speaker, thereby affecting the sound quality of the speaker. Contents of the invention [0003] In view of this, it is n...
