Embodiment Construction

[0012] Below in conjunction with embodiment the working principle of the present invention is specifically described: as figure 1 , a new type of underwater speaker includes a top cover 3, a base 7, and a sound membrane 8, the top cover is sealed and fixed on the upper part of the base, the connection part is guaranteed to be watertight, the sound membrane is fixed on the bottom of the base, and the connection between the sound membrane and the base is also guaranteed to be sealed No water leakage, a vibration driver is fixed in the airtight cavity surrounded by the upper cover, the base and the sound film. Contact, the current lead of the vibration driver is drawn out through the sealing hole 11. The vibration driver places the coil 2 fixed on the vibrating shrapnel 6 in the magnetic field gap of the magnetic circuit device. The structure formed inside the shell 5 of the vibration driver is fixed, and the vibrating shrapnel is fixed on the magnetic circuit device. The shape o...

Abstract

The invention discloses an underwater loudspeaker, comprising an upper cover, a base and a sound film; the upper cover is sealed and fixed at the upper part of the base; the sound film is sealed and fixed at the lower part of the base; a vibration driver connected with the base by a thread is arranged in a chamber enclosed by the upper cover, the base and the sound film; the vibration spring of the vibration driver is fixedly connected with a vibration transmission body; the other end of the vibration transmission body is contacted with the sound film; the current lead wire of the vibration driver is led out by a sealing hole. The vibration driver coil vibrates in a magnetic field after getting electricity and drives the vibration spring to vibrate; the vibration is transmitted by a vibration transmission body and leads the sound film contacted with the vibration transmission body to generate vibration and phonate. The underwater loudspeaker has the advantages that the structure is simple, the clearance where the coil is arranged has strong magnetic field, strong vibration of the coil can be generated by extremely small electrified current, the installablity of the audio equipment is greatly improved, therefore, the vibration driver of the structure is convenient for maintenance, the cost is low, the volume is small, the weight is light and the carrying and installation are convenient.

Description

technical field [0001] The invention relates to the field of audio equipment, in particular to an underwater speaker for playing music underwater. Background technique [0002] The audio device is one of the important tools of information technology, and the loudspeaker is an important component of the audio device. Entertainment, sports, culture, publicity and personal life in modern society have higher and higher requirements for speakers, especially in water ballet, synchronized swimming and other sports where many actions are carried out underwater, and only underwater speakers can be used to play music. , All kinds of beautiful movements can be performed under the accompaniment of music. In addition, music can be played underwater or listened to underwater to have a better effect, which requires high-quality underwater speakers with a wide frequency band. [0003] The vibration driver of the traditional underwater speaker is made of large magnetostrictive material or ...
