Description

High-frequency loudspeaker capable of effectively preventing water

[ technical field ] A method for producing a semiconductor device

The utility model relates to a speaker technical field especially relates to an effective waterproof tweeter.

[ background of the invention ]

The loudspeaker is a transducer for converting an electric signal into an acoustic signal, and the quality of the loudspeaker has great influence on the sound quality. The loudspeaker is the weakest component in the audio equipment, and is the most important component for the audio effect. Loudspeakers are of a wide variety and vary widely in price. The audio frequency electric energy makes the drum paper or the diaphragm vibrate and generate resonance (resonance) with the surrounding air through the electromagnetic, piezoelectric or electrostatic effect to produce sound.

However, the loudspeaker is installed outdoors and is easily wetted by rainwater, so that water accumulated inside the loudspeaker and even components are rusted and damaged, and the service life of the loudspeaker is shortened.

The utility model discloses it is not enough to solve prior art and research and propose.

[ Utility model ] content

The utility model aims at overcoming above-mentioned prior art's shortcoming, providing a can effective waterproof tweeter, can prevent effectively that water from entering into inside the speaker.

The utility model discloses can realize through following technical scheme:

the utility model discloses a high-frequency loudspeaker capable of effectively preventing water, which comprises a basin frame, a rear cover and a voice coil, wherein the basin frame is internally provided with a horn, the bottom of the horn is fixed on the rear cover through a lower horn, the outer periphery of the lower horn is fixed with inner T iron, the outer periphery of the inner T iron is sequentially fixed with outer T iron, a magnet and a washer from bottom to top, the outer T iron is fixed on the basin frame, the washer is fixed at the bottom of the basin frame, gaps are arranged between the inner T iron and the magnet as well as between the washer, the voice coil is in a ring body structure, the voice coil is fixed in the gaps through elastic waves, the elastic waves are fixed in the basin frame, drum paper is fixed on the voice coil, the upper end face of the drum paper is fixed in the basin frame, the drum paper is fixed in the gap between the upper horn and the basin frame, a sound film is fixed between the drum paper and the upper horn, a mesh cloth is fixed in the upper horn, and an iron net is further fixed on the upper horn above the mesh cloth. When the voice coil passes through the audio current, the voice coil performs motion of cutting a magnetic force field in a permanent magnetic field generated by the magnet, so that the voice coil vibrates up and down, drum paper bonded and connected with the voice coil vibrates, air is pushed to vibrate, sound is generated, and sound waves (music which can be heard by people) are transmitted; the principle of energy conversion is as follows: electric energy, magnetic energy and acoustic energy; and drive the common vibrations of sound membrane through the drum paper, further can improve sound signal, and through bugle and last bugle combined action down, enlarge sound signal, it reaches 90% to add the one deck sound transmission rate in the inside of last bugle simultaneously, waterproof dustproof performance can reach the screen cloth of IP65 level, in order to reach waterproof purpose, simultaneously in order to increase the structural rigidity of screen cloth, an iron net comes the separation rivers impact in front of the screen cloth, the sound of the better reduction high pitch of ability, avoid water to enter into inside the speaker.

Preferably, the horn is horn-shaped.

Compared with the prior art, the utility model has the advantages that:

1. the sound transmission rate reaches 90% in the inside one deck of horn, and waterproof dustproof performance can reach IP65 level's screen cloth, can prevent effectively that water from entering into inside the speaker.

2. An iron net is added in front of the net cloth to block water flow impact, so that the structural rigidity of the net cloth is further increased, and the service life of the device can be effectively prolonged.

3. The sound film is driven to vibrate together through the drum paper, and the sound signal can be effectively improved.

4. The sound intensity is enlarged through the combined action of the lower horn and the upper horn.
