Description
Technical Field
The utility model belongs to the technical field of the speaker, specifically relate to a from waterproof speaker of pressure release.
Background
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. The variety of speakers is wide. The audio frequency electric energy makes the cone or diaphragm vibrate and generate resonance with the surrounding air to make sound through electromagnetic, piezoelectric or electrostatic effect.
The back sound chamber of traditional speaker has two kinds, one kind is for taking the back sound chamber of letting out the atmospheric pressure hole, one kind is airtight type back sound chamber, the speaker of taking the back sound chamber of losing the atmospheric pressure hole produces the heat at the during operation, back sound chamber air begins the heat to rise, produce air pressure, the pressure value lasts the increase, when the loss of qi pressure hole discharge of back sound chamber is not enough, expanding gas begins to oppress the speaker vibrating diaphragm, it is unbalanced to cause the vibrating diaphragm vibration, produce sound and the timbre phenomenon, it is more obvious that above-mentioned phenomenon appears in the speaker of airtight type back sound chamber.
SUMMERY OF THE UTILITY MODEL
The utility model mainly solves the technical problem existing in the prior art and provides a self-pressure-relief waterproof loudspeaker.
The above technical problem of the present invention can be solved by the following technical solutions: the utility model provides a from waterproof speaker of pressure release, includes the casing, the inside of casing is provided with back sound chamber and preceding sound chamber, back sound chamber has been seted up for airtight type or bottom and has let out the atmospheric pressure hole, the inside fixed mounting of casing has the speaker support, the downside fixed mounting of speaker support has the speaker magnetic circuit, the outside of speaker magnetic circuit is provided with speaker coil, speaker coil is provided with the speaker vibrating diaphragm with the upside of support, the upside of speaker vibrating diaphragm sets up the vocal membrane, the speaker vibrating diaphragm has seted up from the pressure release hole with the surface of vocal membrane.
Preferably, a waterproof and breathable film is arranged on the upper side of the sound-generating film.
Preferably, the sound-generating film is made of a rigid light and thin sheet material.
The utility model discloses beneficial effect who has:
1. the utility model discloses a set up from the pressure release hole on vibrating diaphragm and sound generating diaphragm surface, from the attached waterproof ventilated membrane in pressure release hole surface, when the machine lasts intensifies or intensifies rapidly, back sound intracavity air inflation, the pressure increase, back sound intracavity pressure release hole loss of qi volume appears inadequately, carry out automatic pressure release from the pressure release hole that the sound generating diaphragm surface of speaker special design was seted up, eliminate the gas pressure because of machine work heat production, protection speaker vibration system's normal balance, do not change the original electroacoustic characteristic of speaker.
