Description
() ГОЛОВКА ЭЛЕКТРОДИНАМИЧЕСКОГО ЗВУКОСНИМАТЕЛЯ() HEAD OF ELECTRODYNAMIC SOUNDER
Изобретение относитс к приборостроению и может быть использовано при изготовлении головок электродинамических звукоснимателей. Известна электромагнитна головка звукоснимател , у которой микрс5магниты закреплены на конце иглы 1. Однако эта головка не обеспечивает равномерную частотную характеристику из-за вли ни зависимости намагниченности сердечника от, частоты воспроизведени сигнала. По основному авт, св. ff известна головка звукоснимател эле тродинамического типа, содержаща иглодержатель, на котором закреплены и кромагниты, полюса которых расположены под углом 9о д|зуг к другу и под углом kS по отношению к продол ной оси иглы 2 . Однако эта головка сложна в изготовлении . Цель-изобретени - упрощение конструкции и повышение равномерности частотной характеристики головки звy коснимател . Поставленна цель достигаетс тем, что микромагниты закреплены непосредственно на иглодержателе, расположенном в промежутке между секци ми катушек, при этом точка укреплени иглодержател к корпусу головки расположена между микромагнитами. На фиг. 1 показан иглодержатель, в сборе; на фиг. 2 - катушка, в сборе; на фиг. 3 расположение катушек Головка электродинамического звукоснимател содержит микромагниты 1, закрепленные непосредственно на иглодержателе 2, Иглодержатель 2 укреплен на демпфирующей шайбе 3 и через вставку k св зан с иглой 5. Катушка головки состоит из магнитопровода 6, на котором размещены каркасы секций 7, заполненные обмоткой 8, и прокладок 9 предохран ю1цих обмотку , и иглодержатель.The invention relates to instrumentation and can be used in the manufacture of electrodynamic pickup heads. The electromagnetic pickup head is known, in which microfiber magnets are attached to the end of the needle 1. However, this head does not provide a uniform frequency response due to the influence of the dependence of the magnetization of the core on the frequency of reproduction of the signal. On the main auth, sv. ff is an electrodynamic type pickup head, which contains a needle holder, on which are also installed crimp magnets, the poles of which are located at an angle of 9 ° to each other and at an angle of kS with respect to the longitudinal axis of the needle 2. However, this head is difficult to manufacture. The purpose of the invention is to simplify the design and improve the uniformity of the frequency response of the head of the tinker. The goal is achieved by the fact that the micromagnets are fixed directly on the needle holder located between the coil sections, while the point of reinforcement of the needle holder to the head body is located between the micromagnets. FIG. 1 shows the needle holder assembly; in fig. 2 - coil assembly; in fig. 3 arrangement of the coils The head of the electrodynamic pickup contains micromagnets 1 mounted directly on the needle holder 2, the needle holder 2 is fixed on the damping washer 3 and through the insert k is connected to the needle 5. The coil of the head consists of the magnetic core 6, on which are placed the frames of sections 7 filled with winding 8 , and gaskets 9 protects the winding, and the needle holder.
При работе звукоснимател колебани иглы 5 через вставку передаютс иглодержателю 2 и соответственно микромагнитам 1, которые, двига сь, индуцируют в обмотке 8 ЭДС, знамение которой пропорционально воспроизводимому сигналу.When the pickup is operating, the vibrations of the needle 5 are transmitted through the insert to the needle holder 2 and, accordingly, to the micro-magnets 1, which, when moved, induce an emf in the winding 8, the sign of which is proportional to the reproduced signal.
