Abstract

The utility model discloses a fixed-line telephone which comprises a telephone body, a telephone receiver and a conversation control circuit; the telephone receiver is connected with the telephone body through a cable or a wireless device; the conversation control circuit is the series loop of a telephone battery, a telephone connection circuit and a hall device; the hall device is arranged on the position of a circuit board inside the telephone corresponding to a receiver in the telephone receiver. When the telephone receiver is placed on the telephone body, the electromagnetic field in the receiver enables the hall device to disconnect, so as to disconnect the conversation control circuit; when the telephone receiver is taken up, the hall device is connected, so as to connect the conversation control circuit. The technical proposal in the utility model is adopted to realize the put-through and hang-up functions of the fixed-line telephone; meanwhile, the shape and weight of the telephone receiver can be adjusted according to the model style of the telephone, so the telephone cost is reduced and fixed-line telephone is convenient and reliable in use.

Description

A kind of fixed telephone

Technical field

The utility model relates to a kind of telephone device, relates in particular to a kind of fixed telephone with independent receiver.

Background technology

It all is to adopt the hook switch mode basically that present common on the market fixed telephone is hung up mode: the hook switch mode is to adopt general dpdt double-pole double-throw (DPDT) or six pin biserial PCB terminals, as shown in Figure 1, on telephone set, place take-up button 102 of Position Design of receiver, when receiver is placed on assigned position, take-up button 102 is depressed, take-up button 102 pressing hook switch mechanisms 101 cause hook switch mechanism 101 and internal circuit to disconnect, thereby telephone set are hung up.When receiver is picked up, hook switch mechanism 101 stressed reducing, it can utilize the spring of self inside that take-up button 102 is lifted, and connects internal circuit, thereby realizes the connection of telephone set.

Adopt the telephone set of hook switch mode to have following defective: 1, very high to the quality requirement of hook switch, in case the elastic force of hook switch is bigger than normal, perhaps displacement can not reach requirement, and this kind mode will lose efficacy.2, relatively stricter for the height dimension required precision of take-up button, may or use wearing and tearing to cause hook switch not press tightly or lost efficacy because of mismachining tolerance in actual applications.3, must reach the purpose that hook switch and internal circuit are disconnected owing to depress the power of hook switch by the take-up button, require receiver must reach constant weight, otherwise can't hang up the telephone, this just need increase materials such as counterweight in handle, cause the increase of telephone set manufacturing cost.

The utility model content

The technical problem that the purpose of this utility model solves is, a kind of fixed telephone is provided, the hook switch mode that overcomes existing control telephone set break-make to mechanical part make require high, and the defective of hook switch mechanism inefficacy easy to wear.

The technical solution adopted in the utility model is, described fixed telephone, comprise telephone body, receiver and conversation control circuit, described receiver is connected by cable or wireless device with described telephone body, described conversation control circuit is the loop that is composed in series by telephone set battery, closing of the circuit circuit, hall device, on the circuit board of telephone set inside with receiver in the corresponding position of receiver be provided with described hall device.When receiver was placed on the telephone set main frame, the electromagnetic field in the receiver disconnected hall device, thereby disconnected the conversation control circuit, and when picking up a receiver, hall device is connected, thereby connected the conversation control circuit.

Adopt technique scheme, the utility model has following advantage at least:

The action of a magnetic field that fixed telephone described in the utility model utilizes receiver to produce is controlled in the machinery that hall device replaces between take-up button and the hook switch mechanism, when the connection that realizes fixed telephone and hanging up function, the profile of receiver and weight also can be adjusted according to the telephone set shaping style fully, reduced the cost of telephone set, simplified the structure.In addition,,, just can realize that phone hangs up, the phenomenon not hung up of plain old telephone can not occur through regular meeting's appearance as long as receiver is placed on assigned position because hall device is the displacement that utilizes magnetic force to produce, easy to use and reliable.In order to make better the having an effect of hall device, only need to adjust the distance of telephone set internal circuit board and telephone set host housing, can adjust the height of hall device easily.

Embodiment

For further setting forth the utility model is to reach technological means and the effect that predetermined purpose is taked, below in conjunction with accompanying drawing and preferred embodiment, to the fixed telephone that the utility model proposes describe in detail as after.

In the concrete embodiment of the present utility model, the final assembly figure of fixed telephone as shown in Figure 2.Described fixed telephone comprises telephone body 201, receiver 202 conversation control circuits, the internal structure of described fixed telephone as shown in Figure 3, the receiver of placing on the telephone body 201 301 is one of parts of receiver 202 inside, be in order to describe receiver 202 and normally to be placed on the telephone set main frame herein, receiver 301 residing positions.On the telephone set internal circuit board under the receiver, a hall device is set, hall device can be a Hall switch 302 here, this Hall switch 302 is subjected to the effect in receiver 301 magnetic fields can make action.Can adopt flexible connection between Hall switch 302 and the circuit board.

As shown in Figure 4, the conversation control circuit is the loop that is composed in series by telephone set battery, closing of the circuit circuit, Hall switch 302, when receiver is placed on the telephone set main frame, electromagnetic field in the receiver 301 disconnects Hall switch 302, thereby disconnect the conversation control circuit, when picking up a receiver, Hall switch is not subjected to receiver 301 electromagnetic field effects to be returned to on-state, thereby connects the conversation control circuit.

The action of a magnetic field that fixed telephone described in the utility model utilizes receiver to produce is realized the connection of fixed telephone and is hung up function in hall device, has reduced the cost of telephone set, simplifies the structure.In addition,,, just can realize that phone hangs up, plain old telephone can not occur, be easy to use reliably through the phenomenon of not hanging up that regular meeting occurs as long as receiver is placed on assigned position because hall device is the displacement that utilizes magnetic force to produce.

In order to make better the having an effect of hall device, only need to adjust the distance of telephone set internal circuit board and telephone set host housing, can adjust the height of hall device easily.Placing on the fixed telephone main body under the position of receiver can complete closed, also perforate as required, and such design helps preventing dust, insect protected.

Explanation by embodiment, can be to reach technological means and the effect that predetermined purpose takes to be able to more deeply and concrete understanding to the utility model, yet appended diagram only provide with reference to the usefulness of explanation, be not to be used for the utility model is limited.
