Abstract
The utility model relates to a microphone, which comprises a casing and a sound pickup, wherein the housing is provided with a concave cavity; the sound pickup is fixed inside the concave cavity. An elastic film is arranged right above the pickup, and is fixed outside the concave cavity to seal the concave cavity. A cavity is formed between the sound pickup and the elastic film. While in use, different from the traditional microphone which adopts the air as a sound conducting medium, the microphone is attached to the skin which vibrates while a user speaks and the sound is conducted to the microphone through the human body skin which serves as the sound conducting medium. When the skin vibrates to drive the elastic film to vibrate, the sound is collected by the cavity and the sound inside the cavity is pressed by the vibrating elastic film, so that the sound of the sound pickup is enhanced with the principle same as a stethoscope which is used by a doctor and the effect of communication is clearer. The sealed microphone is attached to the skin to isolate the noise transmitted by the air, so that the effect of sound picking is not affected by the surrounding environment. Sealing the concave cavity, the elastic film also performs the function of water resistance. Being protected, the sound pickup has longer service life, more durability and more stable performance.
Description
Technical field
The utility model relates to a kind of microphone.
Background technology
On the market microphone miscellaneous is arranged now, supra-aural, head hoop formula, hand-hold type etc. are arranged, these microphones all are to be fixed on by different way near near user's mouth, it only is the media of conduction sound with the air, can't completely cut off the noise of the surrounding environment of coming, have a strong impact on communication effect by air transmitted.The consumer thirsts for having a kind of surrounding environment influence, microphone that pickup effect is good of not being subjected to.
The utility model content
The purpose of this utility model is, the microphone that a kind of pickup effect is good and noise immunity is strong is provided.
The purpose of this utility model is achieved through the following technical solutions:
A kind of microphone includes shell, pick-up, and described microphone is provided with the pickup intensifier;
Described pickup intensifier is made up of elastic membrane and cavity;
Described shell is provided with cavity, and described pick-up is located in the described cavity, and described film is located at described cavity outer end, forms described cavity between described film and the described pick-up;
Described cavity internal chamber wall is provided with boss, and described pick-up is fixed on the described boss, and is connected with external equipment to pass the lead that described shell stretches into described cavity;
Described elastic membrane is the PE film, and described cavity ecto-entad narrows down gradually;
Described microphone also is provided with a lid, describedly is covered on described cavity outer end and pushes down described elastic membrane;
Described lid is to be provided with openwork part, and described lid is shape (also other shapes that engage with shell) ringwise.
The beneficial effects of the utility model have: microphone case is provided with cavity, and pick-up is fixed in the cavity, is provided with one deck elastic membrane directly over the pick-up, and elastic membrane is fixed on cavity outer end (being the shell outside), and cavity is sealed up.Like this, form cavity between pick-up and the elastic membrane.When using this microphone, microphone is attached to speak with the user and produces on the skin that shakes (as: lower jaw, throat, chest).Utilize human body skin to pass to microphone for the sound conduction media, different with the conventional microphone that only is the sound conduction media with the air.Drive the elastic membrane vibrations when skin shakes, sound is collected by cavity, and the elastic membrane of vibrations is pressurizeed to the sound in the cavity, and the sound that arrives pick-up is strengthened, and principle is the same with the stethoscope (non-electronic type stethoscope) that the doctor uses, and it is more clear to converse.The microphone of sealing is attached to and has intercepted the noise that is transmitted by air on the skin, and pickup effect is not subjected to surrounding environment influence, and noise immunity is strong.Elastic membrane has sealed cavity, also can play waterproof action, and pick-up is protected, and the life-span is longer, durable, and performance is more stable.
Description of drawings
Fig. 1 is the structural representation of a kind of microphone described in the utility model.
Embodiment
The utility model will be further described to reach specific embodiment now in conjunction with the accompanying drawings.
As shown in Figure 1, a kind of microphone described in the utility model includes shell 1, pick-up 2, be provided with a cavity 11 in the shell 1, chamber wall near cavity 11 inner bottom surfaces is provided with boss 12, pick-up 2 bottoms are pressed on the boss 12 and available glue clings, but also electricity consumption high-frequency electrical or ultrasonic welding method are fixed, and pick-up 2 is fixed in the cavity 11.Pick-up 2 is connected with external equipment (as bluetooth earphone, mobile phone) with the leads 3 that pass shell 1 side through hole and stretch in the cavity 11.Be provided with one deck elastic membrane 4 directly over the pick-up 2 (as the PE film, be Polyethene, polyethylene film), elastic membrane 4 can be fixed on cavity 11 outer ends (being shell 1 outside) by high-frequency electrical or ultrasonic welding method, cavity 11 is sealed up, and cavity 11 outer ends are provided with the inclined-plane to pick-up 4, like this, form the ecto-entad cavity 5 that narrows down gradually between pick-up 2 and the elastic membrane 4, its collection effect is better.When using this microphone, microphone is attached to speak with the user and produces on the skin that shakes (as: lower jaw, throat, chest), and elastic membrane 4 contacts with skin.Utilize human body skin to pass to microphone for the sound conduction media, different with the conventional microphone that only is the sound conduction media with the air.When shaking, skin drives elastic membrane 4 vibrations, sound arrives cavity 5 through elastic membrane 4 and is collected, sound in 4 pairs of cavitys of elastic membrane 5 of vibrations pressurizes, the sound that arrives pick-up 2 is strengthened, principle is the same with the stethoscope (non-electronic type stethoscope) that the doctor uses, and it is more clear to converse.The sealing microphone be attached to intercepted on the skin by air transmit noise, pickup effect is not subjected to surrounding environment influence, noise immunity is strong.Elastic membrane 4 has sealed cavity 5, also can play waterproof action, and pick-up 2 is protected, and the life-span is longer, durable, and performance is more stable.Microphone also is provided with the lid 6 of a center hollow out, shape ringwise, and covering 6 set openwork parts can be the same big with cavity 11 outer end openings, and elastic membrane 4 is fully contacted with skin.Lid 6 can also be other shapes that can engage with shell 1.Lid 6 can be bonded at shell 1 outside and push down elastic membrane 4 with glue, and also available high-frequency electrical or ultrasonic welding method are fixed, and elastic membrane 4 is more fixing, and microphone is more attractive in appearance.
