Abstract

The utility model discloses a Chinese class hearing aid for students attending lectures, which is characterized by being formed by a pen-type casing (1), a pen cap (5), a circuit board (2), a hanger (3) and a bone conduction head (4). The circuit board (2) is mounted inside the pen-type casing (1), a battery is mounted inside the pen cap (5), a press power switch (6) is arranged at the top end of the pen cap (5), the hanger (3) is fixed on one side of the pen cap (5), and the bone conduction head (4) is connected onto the circuit board (2) through a conductor (7). The hearing aid has simple structure and convenient use, and by adopting the bone conduction means to enhance hearing, a user can hear normal lecturing voices of a teacher through air conduction, and also the normal lecturing voices of a teacher can be amplified through the bone conduction means so as to enhance hearing and favor students' attendance effect. The hearing aid can be widely used for Chinese teaching.

Description

The student pays attention to the class the Chinese course hearing hearing aids of usefulness
Technical field
The utility model relates to a kind ofly assists the not good enough student of hearing to listen the student of Chinese course to pay attention to the class the Chinese course hearing hearing aids of usefulness.
Background technology
In Chinese language is given lessons, have many classmates bad because of the not good enough achievement of hearing, the reason that hearing is not good enough has multiple, comprises student's self reason, the vocabulary of grasping as student itself very little, the knowledge of grammar lacks, mood is too irritable, reaction speed is slow, energy dispersion etc., certainly a little less than the sense of hearing that also has.External cause is also arranged, as the interference of external environment.For the more weak problem of the sense of hearing that has physiological reason to cause, the employing earplug hearing aid that has, but earplug stops earhole simultaneously, earplug is audition by air transmitted, and a class earplug is because the time is longer, feel under the weather, and the effect of increase hearing is also not ideal enough.At present, also be not exclusively used in the report that improves student's hearing devices.
Summary of the invention
The purpose of this utility model is to provide a kind of earhole that neither stops up, and the hearing aid effect is arranged again, and simple in structure, easy to use, be exclusively used in the Chinese course hearing hearing aids that student that the not good enough student of hearing listens to the teacher pays attention to the class usefulness.
For reaching above purpose, the technical scheme that the utility model adopted is: this student pays attention to the class the Chinese course hearing hearing aids of usefulness, it is characterized in that it is made of pen type housing, the cap for brush, circuit board, hook, bone conduction head, circuit board is contained in the pen type housing, and fixing, battery is housed in the cap for brush, be provided with the push type mains switch on cap for brush top, hook is fixed on a side of the cap for brush, and the bone conduction head is connected on the circuit board by lead.
The utility model is also implemented by following measure: the electric elements on the described circuit board comprise that triode BG1, BG2, BG3, BG4, microphone M, diode D and electrochemical capacitor C1, C2, C3, C4, C5 and resistance R 1, R2, R3, R4, R5, R6, volume potentiometer W form, and wherein triode BG1, BG2, BG3 are three grades of direct manifold type feedback amplifiers; Be provided with diode D in the base loop of triode BG4, can play temperature compensation function, also play certain automatic volume control action; Triode BG1, BG2, BG3 can adopt 3AX23, and BG4 can adopt 3AX81; Diode D can adopt germanium tube; Electrochemical capacitor C1, C2 adopt tantalum electric capacity, are beneficial to dwindling of volume; The bone conduction head G that described bone conduction head adopts market to sell.
The beneficial effects of the utility model are: simple in structure, easy to use, owing to adopt the bone conduction mode to increase hearing, so, can hear teacher's normal teaching voice by air transmitted, can enlarge by the normal teaching voice of bone conduction mode again teacher, increase hearing, help increasing student's the effect of listening to the teacher.

Embodiment
Make the utility model with reference to Fig. 1,2.This student pays attention to the class the Chinese course hearing hearing aids of usefulness, it is characterized in that it is made of pen type housing 1, the cap for brush 5, circuit board 2, hook 3, bone conduction head 4, circuit board 2 is contained in the pen type housing 1, and it is fixing, in the cap for brush 5, battery is housed, be provided with push type mains switch 6 on the cap for brush 5 tops, hook 3 is fixed on a side of the cap for brush 5, and bone conduction head 4 is connected on the circuit board 2 by lead 7.When using the utility model, pen type housing 1 can be contained in the coat pocket, hang over coat pocket along last, bone conduction head 4 is close to behind the ear gets final product on the mastoid process with linking up with 3.
Electric elements on the described circuit board 2 comprise that triode BG1, BG2, BG3, BG4, microphone M, diode D and electrochemical capacitor C1, C2, C3, C4, C5 and resistance R 1, R2, R3, R4, R5, R6, volume potentiometer W form, wherein triode BG1, BG2, BG3 are three grades of direct manifold type feedback amplifiers, gain is high, working stability, same bandwidth, distortion is little; Be provided with diode D in the base loop of triode BG4, can play temperature compensation function, also play certain automatic volume control action; Triode BG1, BG2, BG3 can adopt 3AX23, and BG4 can adopt 3AX81; Diode D can adopt germanium tube; Electrochemical capacitor C1, C2 adopt tantalum electric capacity, are beneficial to dwindling of volume.The bone conduction head G that described bone conduction head adopts market to sell.
