Abstract
The utility model relates to a bone-conduction microphone, which comprises a piezoelectric ceramic (5) and an external wire (7), wherein the anode and the cathode of the piezoelectric ceramic (5) are respectively connected with the anode and the cathode of the external wire (7). The bone-conduction microphone further comprises a sealed metal casing, and the piezoelectric ceramic (5) is fixedly arranged in the metal casing. The piezoelectric ceramic of the bone-conduction microphone is fixedly arranged in the metal casing, and the rigidity of the metal casing is better, which can effectively inhibit 'air conduction' and increase 'bone conduction' and sensibility, and improves the voice transmitting quality.
Description
Technical field
The utility model relates to Communication Equipment, is specifically related to transmitter, particularly the osteoacusis transmitter.
Background technology
At present, known osteoacusis transmitter is that piezoelectric ceramic forms by Plastic Package, and " piezoelectric effect " by piezoelectric ceramic collects user's skull vibration that vocal cords drive when speaking, and the vibration signal that collects converted to the signal of telecommunication again and realizes conversation.There is following defective in present osteoacusis transmitter: 1, in the vibration signal of gathering skull, other noise in the environment is also collected by piezoelectric ceramic by aerial vibration, and just " conductance " is transaudient, influences sending speech quality; 2, because the osteoacusis transmitter wants cube less, there is not buffering to pick up to vibration signal, cause the scope that frequency is picked up wide, also can influence sending speech quality.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of conduction transmitter is provided, and the sending speech quality of this osteoacusis transmitter is good.
The utility model solves the problems of the technologies described above the technical scheme that is adopted:
A kind of osteoacusis transmitter, it comprises piezoelectric ceramic, external wire, the positive and negative electrode of piezoelectric ceramic is connected with the positive and negative electrode of external wire respectively; The osteoacusis transmitter also comprises the metal shell of sealing, and piezoelectric ceramic is fixedly installed in the metal shell.
In the such scheme, metal shell is made up of spill loam cake and spill base, and loam cake is relative with the spill mouth of base, and loam cake is buckled in the base, forms hollow cylinder.
In the such scheme, also be provided with connecting circuit plate, enamelled wire in the metal shell; The negative pole of piezoelectric ceramic is connected by the negative pole of metal shell with the connecting circuit plate, and the positive pole of piezoelectric ceramic is connected by the positive pole of enamelled wire with the connecting circuit plate; The positive and negative electrode of external wire is connected with the positive and negative electrode of connecting circuit plate respectively.
In the such scheme, also be provided with ring washer in the metal shell, the connecting circuit plate is arranged on the base bottom, and ring washer is pressed on the connecting circuit plate, and the spill mouth of loam cake is pressed on the ring washer; The negative pole of piezoelectric ceramic is pressed between loam cake and the ring washer.
In the such scheme, the bottom of base stretches out.
The utility model osteoacusis transmitter, its piezoelectric ceramic is fixedly installed in the metal shell, and the metal shell rigidity is better, can effectively suppress " conductance " and can increase " bone conduction " and sensitivity, has improved the sending speech quality of osteoacusis transmitter.
The utility model also has the following advantages:
1, metal shell is a hollow cylinder, and it is made up of spill loam cake and spill base, and its assembling is simple, good sealing effect.
2, also be provided with the connecting circuit plate in the metal shell, external wire is connected with piezoelectric ceramic by the connecting circuit plate, helps the connection of external wire.
3, also be provided with ring washer in the metal shell, the negative pole of piezoelectric ceramic is pressed between loam cake and the ring washer, thereby be fixed in the metal shell piezoelectric ceramic is unsettled, can play cushioning effect to vibration signal, control the scope of picking up of frequency, made the vibration signal that picks up of the more accurate sensitivity of piezoelectric ceramic energy.
4, the bottom of base stretches out, and has increased the contact area of osteoacusis transmitter and human body, helps the osteoacusis transmitter and picks up vibration signal.
